W O R K S H O P Schaeffler industry manager for raw materials, Mike White, “The new sealed version of our high performance 241/1250 bearing is expected to offer significantly longer operating life, while substantially reducing the cost of preventative maintenance to the end user. Schaeffler is committed to helping our mining partners produce more while consuming fewer resources. We are very proud to be the first bearing manufacturer to offer this design improvement to the mining industry.” The importance of maintenance and monitoring High quality bearings are a worthwhile investment because they will operate reliably for longer. In order to optimise the performance and operating life of such a valuable investment, proper maintenance and monitoring is essential. In some cases, it can as much as double the operating life of the bearing. 46 September 2017 One method is to install monitoring technology such as Schaeffler’s FAG SmartQB (incorporating SmartCheck technology) ready-touse monitoring solution for electric motors, pumps, and fans. It is easy to install and does not require any specific knowledge about vibration diagnosis, including for common installations such as vibratory, grinding and rolling processes. Another innovative new method is to use the bearing as the monitoring device. Schaeffler has recently introduced to Australasia its new and radically advanced VarioSense roller bearings that report on their own condition and load through built-in sensor clusters. Schaeffler’s new FAG VarioSense bearings are configurable sensor bearings for monitoring machines, processes, bearing condition and load across diverse industries where downtime is costly and maintenance is expensive. To complement advanced bearing technologies and monitoring solutions, a maintenance programme tailored to each individual application is ideal. In addition to checking that the bearing is operating properly and without contaminants, this should include relubrication to ensure the bearing does not suffer any premature damage. Bearing contamination INTERLOCKING PRONAL PLATFORM LIFTING BAGS RAISE THE BAR Interlocking stackable Pronal heavy lift cushions are being introduced by Air Springs Supply for heavy horizontal raising and rescue tasks across major sectors, including automotive, construction, electrical, infrastructure, materials handling, resources, transport and government utilities. The CPF 10 bar (145psi) platform lifting bags – with individual starting thicknesses of just 25mm and individual lifting capacities up to 84.6 tons – can be stacked in threes for extremely stable lifts up to 510mm. Their flat, interlocking tops and bottoms make them a most forgiving and effortless lifting solution in compromised and difficult stabilisation situations including in softer, irregular and remote areas, says James Maslin, national sales and marketing manager for Air Springs Supply, distributor for Pronal products. Areas in which the CPFs excel include: • Lifting of pressure vessel, electrical machinery and fabricated steel components, including manufacturing, energy utility and infrastructure environments • Emergency removal of heavy weights (slabs, beams) from trapped people and objects, including construction and resources developments • Machine height adjustment in multiple industrial and materials handling environments • Raising of vehicles and mobile machinery, including recovery operations in civil and industrial environments • Maintenance services Available in individual lifting capacities of 31.4 to 84.6 tons, the five models of CPF bags weigh from just 11 to 26kg, adding to their safe ease of handling and positioning in awkward and emergency situations. “These robust, smooth and powerful lifters – built to the same Pronal global standards trusted by military, civil, aviation and maritime authorities – are the ideal product to lift heavy horizontal objects effortlessly,” says Mr Maslin. The cushions’ flat, interlocking tops and bottoms enable them to be safely and easily stacked in threes, offering a most forgiving and safe solution in stabilisation situations. A secure lifting column is created by the weight of the object being lifted and the surface of the lifting bag. Made from several layers of elastomer, they are vulcanised under vacuum in an autoclave for dependable long-life performance, says Mr Maslin. CPF lifting bags offer constant lifting power during the entire lift, a safety factor of 3 (bursting pressure V working pressure), High burst pressure, can operate in conjunction with conventional control systems, have maximum stacking in threes and include accessories such as Deadman controllers, inflation hoses, adaptors, shut-off unit and pressure regulator.
