Yamato introduces next-day delivery on genuine spare parts

Yamato Scale Dataweigh UK has launched a standard next-day delivery service on genuine spare parts for its ranges of multihead weighers and checkweighers.

Genuine Yamato spare parts are superior in quality to non-genuine parts. They enable engineers to service and repair automatic weighing machines to high standards of quality and reliability.

“There is an increasing market for 'pirate' or non-genuine parts for weighing machines, multihead weighers and checkweighers used in processing plants of all kinds,” said Andrea Spencer, commercial operations manager at Yamato Scale Dataweigh UK.

2017 04 26 085230Yamato is offering next-day delivery on all its genuine spare parts from stock.

“Under-pressure plant managers often opt for cheaper pirate parts but there are very good reasons why this practice should be avoided as an example of false economy.

“We are now reinforcing the benefits of genuine parts by providing standard next-day delivery on Yamato spares from stock at no extra cost to the customer. This will help our customers to save money by reducing downtime caused by parts failure and scheduled maintenance.”

If a pirate part is being installed there is no guarantee that the component, which may have minute differences to genuine parts, will run effectively. Failure of the pirate part may involve consequential damage to connected components resulting in wider damage and associated costs.

Getting genuine spare parts more quickly will help solve this problem. Keeping an inventory of genuine spare parts guarantees security, quality, performance and longevity.

Yamato’s Paul Ingall said: “When choosing between original parts or corresponding copy products you need to assess both the costs of the parts and the risks associated with their use.

“These costs are not only those related to the individual part but also include the labour for the interruption to service and the machine downtime which can be caused by premature failure. Getting parts within a day of needing them will help to cut downtime and costs.”

Yokogawa releases enhanced version of ProSafe®-RS Safety Instrumented System

Yokogawa Electric Corporation announces that it will release an enhanced version of the ProSafe®-RS safety instrumented system on April 26. This latest release, R4.03.00, includes an improved engineering function for configuring fire and gas systems (FGS) and new operation faceplates for the FGS operation and monitoring screens. These enhancements make it easier to adopt and use ProSafe-RS in FGS applications.

Development Background

In the oil, natural gas, petrochemical, chemical, and other energy and basic materials industries, various safety measures must be taken to prevent accidents and protect the environment. This includes the use of a safety instrumented system, which can secure plant safety by functioning as an emergency shutdown system (ESD) that detects abnormal conditions and safely initiates emergency shutdowns, and by functioning as an FGS.

2017 04 20 112040

Yokogawa’s ProSafe-RS safety instrumented system can be integrated with the CENTUM VP integrated production control system and is widely used mainly in ESD applications all over the world. Based on an April 2017 Yokogawa survey, ProSafe-RS is one of the top selling safety instrumented systems on the market today. Since releasing this system in 2005, Yokogawa has continued to strengthen its functions to satisfy a variety of customer needs. In response to the rising need for FGS solutions, this latest release includes features that make it easier to adopt and use this system in such applications. And by adding a new input/output (I/O) module and enabling the use of an alternate control network topology, we are giving our customers a greater range of choices in their ESD and FGS applications. Cybersecurity has also been strengthened.


  1. Easier adoption and use in FGS applications

Software components (function blocks) that define the operations and functions to be performed when smoke, heat, and/or gas is detected, an essential aspect of any FGS application, have been added to the ProSafe-RS engineering functions. Standard FGS faceplates have been added for the integrated display of smoke, heat, and gas detector information such as gas concentration level and device status. In addition, the I/O module has a new function that can reset the detector that sends smoke and heat detection signals to the ProSafe-RS system. This eliminates the need for a reset circuit to restore communications after an abnormality is detected, thus reducing both the size of the hardware and its initial cost. With these enhancements, the ProSafe-RS is easier to adopt and use in FGS applications.

  1. New I/O module

Yokogawa provides an N-IO (Network-IO) I/O device with channels that can be configured by software to handle either analog or digital signals. As most safety instrumented systems rely mainly on digital I/O signals, the company has added a new I/O module to its lineup that is used for only the input or output of digital signals. This new module reduces the total cost of ownership for users.

  1. Ring network topology

For the Vnet/IP® real-time control bus, ProSafe-RS has relied on the star network topology, in which all devices are connected to a central hub. Vnet/IP is a control network developed by Yokogawa that features high reliability and quick response. Vnet/IP complies with the IEC61784-2 international standard. The new ProSafe-RS is also compatible with the ring topology, in which devices are connected to each other in the shape of a ring. This feature affords our customers greater flexibility when configuring their systems.

  1. Improved cybersecurity

As a result of enhancements made to the ProSafe-RS engineering station’s software security functions and changes to the Windows® security settings, users can now set their systems to a higher security level. This latest ProSafe-RS release also supports a Windows function that enables the centralised management of security settings. With this feature, users can apply the same security settings to multiple monitoring and operation PCs, thus greatly improving plant security.

Major Target Markets and Applications

For use in emergency shutdown systems (ESD), burner management systems (BMS), and fire and gas systems (FGS) in process industries such as oil, natural gas, petrochemicals, chemicals, pharmaceuticals, electric power, and iron and steel

About ProSafe-RS

Released in February 2005, the ProSafe-RS safety instrumented system helps prevent accidents by detecting abnormal conditions in plant operations and initiating emergency actions such as a plant shutdown. An independent certification body has certified that ProSafe-RS conforms to the IEC61508 international safety standard and can be used in SIL3applications. Established by the IEC, a safety integrity level (SIL) indicates the relative level of risk provided by a safety function. SILs 1 through 4 are defined by IEC 61508. At SIL3, the risk factor for a plant where safety measures are not in place is in a range between 1/1,000 and 1/10,000. At SIL4, the risk factor is in a range between 1/10,000 and 1/100,000. Unlike conventional safety instrumented systems and distributed control systems, which are regarded as having different roles and functions and operate separately, the operation of ProSafe-RS and the CENTUM integrated control system can be fully integrated. ProSafe-RS is highly regarded by users and has been installed in more than 2,100 projects worldwide (as of April 2017).

How Water Jet Sweden T-model manage to counteract the laws of physics.

Waterjet technology is unique cutting method using natural elements like water, sand and pressure. No heat or chemical substances are being added and no poisonous fumes are created. Natural elements, yes, but these forces must be controlled and is a tough environment for man-made machines. How to build a long-life, high performance waterjet machine starts with some basic design principles. We went into the production hall of world leading waterjet manufacturer Water Jet Sweden to check behind the curtains building the entry level T-model machine.

Heavy-duty steel frame.

To cut heavy materials with a more than 0.1 mm accuracy consistently year after year demands a heavy duty machine design that can manage weight and withstand vibrations over time. The weight of the steel frame ensures machine stability. If you select wrong material or too weak sections on the frame design it can cost a lot in performance. You can easily see the difference if you lift off the cover panels of a waterjet cutting machine.  The massive steel beams of the T-model are designed to consistently withstand vibrations and delicately operate heavy cutting tools and accessories for many years. 

2017 04 19 094045A production hall of Water Jet Sweding in Ronneby building a new batch of T-model entry level waterjet cutting machines.

Complete protection of Moving Parts

Water jet cutting is environmentally friendly cutting method, but it is a tough environment for high tech machines. Many parts are sensitive to the wear of abrasive and water and easy maintenance is key to performance and lifetime.  On the T-model the motion systems are enclosed with full covered bellow protection. This keeps mechanical and electrical parts clean from the abrasive and water while processing and the machine is very easy to clean. Protection of sensitive parts and easy cleaning will secure machine performance, simplify maintenance and significantly prolong machine lifetime. 

Powerful, waterjet optimized, motion system

The motion system of a water jet cutting table must withstand torsion powers, often several hundred kilograms, and at the same time have a smooth movement to keep accuracy and tolerances at tenths of a millimeter. The ballscrew for the X and Y axis is one example for how the T-model motion system is specially designed for water jet cutting. The powerful ballscrew of 32 mm in diameter makes the T-model waterjet machine able manage higher rotation speed. This minimize the risk of wobbling and torsion and secure uptime and lifetime performance. 

Generally, the ballscrew of a Water Jet Sweden machines has quite a low pitch (20 mm/turn). This will give a smooth movement with high resolution and accuracy when cutting. The pitch affect maximum speed, but a maximum cutting speed of 10 000 mm/min (X and Y axis) is more than enough for water jet cutting.  Maximum travel speed (15 000 mm/min I Y and 15 000 mm/min in X) is a more academic figure since travel time normally is a very small part of total processing time.

Choice of motion system guide rails are also important. You must have a stable and straight X and Y axis movement to get consistent cutting quality. Otherwise it is almost impossible to keep accuracy and tolerance measures while cutting. But that’s what a wide and stable guide rail gives you.  For small extra cost the wide guide rails improve machine performance and prolong machine lifetime. The T-model has two wide guide rails on the Y-axis where the main is 90 mm and support 35 mm. The X-axis beam has a stable 70 mm guide rail to make the Z-unit travel steadily. Our broad guide rails resist torsion, unnecessary tension and gives a consistent cutting quality, hour after hour, year after year. 

These are a few examples of mechanical design that enables the five-year performance warranty. Machines built by waterjet specialist in Ronneby, Sweden, devoted to performance.

High performance seal option now available on an extended range of SKF Explorer deep groove ball bearings

Applications requiring larger bearing sizes can now benefit from longer maintenance intervals and greater resistance to contamination.

Gothenburg, Sweden, 13 March 2017: SKF is making its high performance RSH seal design available on a larger range of SKF Explorer deep groove ball bearings. The tried and tested RSH seal uses a highly optimised dual-lip configuration to provide additional protection in demanding environments. For users, the result is bearings that last longer, especially in wet, contaminated or dusty operating conditions, and that need to be replaced less frequently.

A secondary lip on the seal withstands high pressure cleaning and offers increased resistance to the ingress of dust and other contaminants, while the seal’s internal geometry has been optimised for smooth running and improved grease retention.

2017 04 05 085358

The seal is made from acrylo-nitrile-butadiene rubber (NBR), which is resistant to mineral oil based lubricants, petroleum products and animal or vegetable fats. It has an operating temperature range of –40 to +100 °C and up to +120 °C for brief periods.

Previously only available on bearings with an bore diameter of 25mm or less, the RSH seal has now been further developed and tested for use in bearings up to 60mm in bore diameter.

Users can specify SKF Explorer deep groove ball bearings with the new RSH seal installed on one or both sides, depending on the requirements of the end application. The new bearing variants are already being introduced, and the full range will be available worldwide by July 2017. The extended RSH offering joins a growing list of options and improvements in the SKF Explorer range. These include numerous different shield and seal configurations and a choice of cage materials and lubricants.

SKF Explorer was originally developed to take advantage of research into high purity steels with improved fatigue resistance, allowing the development of bearings with a longer rated life and lower friction.

Stocking up on specialist bearings

Bearing supplier introduces marine grade 316 stainless steel bearings

Specialist supplier of miniature bearings, SMB Bearings, has introduced a new range of 316 grade stainless steel ball bearings to its catalogue. The 316 bearing variety has been specially selected for customers with applications operating in harsh environments, which the bearings can withstand thanks to their marine grade stainless steel construction. The bearings will find a home in food processing, chemical manufacture and pharmaceutical production as well as marine and other liquid process applications.

The 316 bearing range can withstand temperatures of up to 500 degrees centigrade (if supplied without cages) and is highly resistant to seawater, salt spray and chemicals. The key difference between 316 stainless steel bearings and other stainless steel bearings is the addition of molybdenum to the metal – an alloy which drastically enhances the corrosion resistance of the bearing.

The full SMB bearings range includes miniature and instrument bearings, plastic bearings, ceramic bearings, stainless steel bearings, thin section bearings and low noise electric motor bearings.

2017 04 05 071041

SMB Bearings supplies 316 stainless steel bearings with polyethylene, PEEK or PTFE cages – all of which provide excellent corrosion resistance to water, salt water and most chemicals. When used in either a PEEK or PTFE cage, the bearings can sustain temperatures of up to 260 degrees centigrade. What is more, bearings from this range can be used in cryogenic applications down to an impressive -250°C, depending on the cage material.

Bearings made with 316 stainless steel are ideal for marine applications that operate above the waterline, but can also be effective when the bearing is temporarily submerged, providing it is regularly washed down with clean water.

316 stainless steel relies on the presence of oxygen to regenerate the passive film on the surface of the steel and, as a result, 316 stainless steel is a less suitable option if the bearing is permanently submerged. For example, in a low oxygen marine environment, when there is no flow of water, the bearing steel may be prone to pitting corrosion.

While the 316 range is ideal for use in harsh environments, bearings manufactured from this material semi-precision and are only suitable for relatively light loads. The more commonly used 440 grade bearings are more ideal for high load and high precision applications – however, 440 grade bearings will suffer from corrosion in the harsh environments in which 316 grade stainless steel could survive.

In addition to its advantages for marine applications, SMB’s range of 316 stainless steel bearings are also suitable for use in the food and beverage industry. In fact, SMB Bearings can provide a relubrication service to replace the standard lubricant supplied with 316 stainless steel bearings with a food grade lubricant.

More information about SMB Bearings’ 316 stainless steel bearing range and its bespoke relubrication service can be found on the company’s website. Alternatively, if you would like to speak to one of the technical experts at SMB Bearings, you can contact the company’s base in Oxfordshire on +44 (0) 1993 842 555.

About SMB Bearings: SMB Bearings originally specialised in miniature bearings, thin-section bearings and stainless steel bearings. By natural progression, the company expanded the range to include other corrosion resistant bearings such as plastic bearings, 316 stainless bearings and ceramic bearings.

Remaining a specialist business, SMB Bearings provide a high level of product knowledge, providing bearing and lubrication solutions to existing or potential customers, whether individuals or large corporations. SMB Bearings does not just sell bearings, but helps to solve your problems.
