July/August 2019 www.pwemag.co.uk Plant & Works Engineering | 33 The JHB Split Bearing As previously mentioned, Bowman recently launched its brand-new range of cylindrical split roller bearings through its Midlands based subsidiary John Handley Bearings subsidiary. The bearing and its components caused quite a splash in the industry when its was first launched at the end of 2018. The entire split bearing has been designed around the bearing cage and the numbers are quite breath-taking; the patent- pending bearing cage, Rollertrain®, has an increased radial capacity of up to 70% and an increased axial capacity of up to 1000% of any other split bearing in the world. The dramatic capacity increases allow the JHB Split Bearing to replace three series of split bearings with a single series which covers almost all existing requirements. The rolling elements within current split bearings are unable to properly accommodate axial and radial loads independently; they only allow for a radial load with a significantly downgraded axial load capacity. The JHB Split Bearing is able to accommodate both loads independently and in so doing enables for the first time the calculation of an axial L10 life. This is a capability that was previously impossible and offers a new dimension of flexibility and design freedom. The bearing offers improvements and added value across the board compared to any other split bearing and genuinely has the potential to Additive Manufacturing Bowman Additive Production (Bowman AP) is the 3D printing division of Bowman International. With the latest HP Multi Jet Fusion technology and engineering grade PA11 material, Bowman AP aims to allow businesses to realize their manufacturing potential through using 3D printing as a production process using a pioneering composite material techniques. Traditionally, additive manufacturing was seen as being too slow and expensive for serious production. However, through the utilisation of the new HP MJF 4200 additive manufacturing system, Bowman AP are now able produce commercial production quantities of parts quickly and accurately with no expensive tooling and with the capability to alter designs to suit individual customer’s needs. Fully tracked delivery gives customers the peace of mind that parts are built to agreed specifications, traceable to source and delivered on time. Some recent examples of production 3D printing are the Rollertrain Bearing Cage and Sealtrain Triple Labyrinth Seals within the JHB Split Bearing. More than a manufacturer Bowman International have been supplying industry with quality parts and services for over four decades and continue to be one of the UK’s leading and most trusted bearings companies. what sets Bowman apart from other manufacturers and distributors are its range of complementary services which include; Comprehensive inhouse testing and inspection services Rapid production of special sizes and one-offs Stock holding facilities Just in time scheduling Design consultancy If you would like to find out more about Bowman’s range of products or to talk about your specific project or application contact them on info@bowman.co.uk or call directly on 01235 462500.

These bearings have been the undisputed market leader in sintered self- lubricating bearings for well over 90 years. Oilite has a rich history dating back to the 1930’s when they were first developed by Chrysler and have since been used in everything from the iconic Supermarine Spitfire aircraft to the latest Formula One racing cars. Today, the Oilite bearing is used in electric motors, aviation cargo systems, escalators, elevators, industrial meters, stage lighting, thermal imaging cameras, medical imaging equipment. The list is almost endless. It continues to set the standard for all other self-lubricating sintered bearings and is still the most popular self-lubricating bearing in the UK. severely disrupt the market by offering design engineers a more flexible, durable and cost-effective alternative to the original split bearings currently available. The Future of Split Bearings is Here: Radial capacity – 70% higher than any other split bearing Axial capacity – 1000% higher than any other split bearing
