PLANT MAINTENANCE, TEST + MEASUREMENT

Industry specialist to help BI grow the agricultural market

We do not compromise on quality, in recognition of the fact that downtime due to component failure is costly,” Trevelyan explains. Some of the leading brands supplied by BI here are KML, FAG, and Koyo bearings, Opti and Continental V-belts, Bauer electric mo- tors, Motodrive worm gearboxes, TR inline gearboxes, Dodge gear- boxes, ABES seals in various sizes, Rocol specialised lubricants, and Kobo chains. BI-branded products include PTO shafts and chain. A range of special sprockets and pulleys is also available, in addition to Citronol hand cleaners and degreasers, and Loctite adhesives and sealants. Tool ranges on offer include Jonnesway hand tools and Makita pow- er tools. Trevelyan highlights that BI has a good relationship with the farming community, largely through industry initiatives such as its longstanding association with Grain SA’s NAMPO Harvest Day in Bothaville in the Free State. “BI is proud to be a part of NAMPO, and will continue to do so. NAMPO gives us a unique opportunity to interact with our cus- tomers, Original Equipment Manufacturers (OEMs), and end users from all over South Africa, to share technical insight, and to show- case our specific products for this market sector.” Enquiries: Email rosst@bearings.co.za LED Stroboscope for front-line troubleshooting Comtest , Fluke’s local representative, has on offer the Fluke 820-2 LED Stroboscope, which they claim is more than just an investigative/ observational tool for measure rotational speed of machinery without physical contact. It’s also a rugged, ergonomically-designed, diagnostic tool which allows for clear observation of machinery in motion for diag- nosing parasitic oscillation, slippage, or unwanted distortions. The 820- 2 LED Stroboscope can effectively be used for frontline troubleshoot- ing, process or product research and development. Cyclic motion can be slowed or stopped visually in order to note performance, observe dynamic motion, measure speed, or photograph/video the action, for many diverse applications in a vast range of industries. The Fluke 820-2 LED Stroboscope features: • High intensity 7-LED array –4 800 Lux @ 6 000 FPM/30 cm • High efficiency LED solid-state light source with uniform flash char- acteristics allow for higher flash rates –30 – 300 000 FPM (flashes per minute) • Digital pulse width modulation for exceptionally sharp images at high speeds • Rugged, durable design utilises solid-state LEDs with no filaments, gases, hollow cavities, or glass – (one metre drop) • Quartz-accuracy control system provides high accuracy-0,02 % (±1 digit) • Multi-line LCD display

Food production security is of utmost importance, especially given how harsh and dynamic an environment the South African agricul- tural industry operates in at present. Leading supplier Bearings International (BI) continues to record good growth in this sector, thanks to its wide range of applicable products. Therefore the company has appointed an industry specialist to look after this market in particular. “We believe that, with additional focus, we can add further value. With this in mind, we will con- tinue with development here in order for us to be able to meet the specific needs of this market sector,” BI Business Unit Head

Ross Trevelyan comments. The com- pany has aligned itself with leading global suppliers. “All the products we offer underscore our promise of hav- ing the right product at the right price for every application in the agricultural industry.
