X-Life quality sealed bearings ward off dust, dirt, and downtime

Bearings on mining equipment rely on three barriers of protection against the ingress of contaminants that are present on mine sites: the housing, the housing seal, and the grease, according to Motion Australia’s in-house bearings expert, Tony Tormey.  In his role as Category Manager for Industrial Bearings, Tony has developed a kind of sixth sense for the subtle differences in bearing performance when they need to contend with dusty and dirty applications such as coal and ore mining operations, aggregate quarries, or mills where raw materials run on conveyors around the clock.  “On heavy industrial applications such as mining and quarrying conveyors, it’s very easy for dust and dirt to penetrate a bearing housing,” explains Tony. “Sometimes when the bearing is being installed, dust in the surrounding air may make contact with the parts as the bearing is being driven up the shaft. Over time, if contaminants continue to build up, the bearing life will start to run down.” “In this instance, any presence of moisture from washdowns or damp environmental conditions will quickly transform dust into sludge further hindering the performance of the bearing,” he continues. “Eventually the bearing will require replacement. And in the worse-case, halt production altogether.” “For this reason, it is extremely important to use advancements in bearings technology to the advantage of our customers that are working with harsh mining equipment,” Tony adds.  On that note, Schaeffler has been on the leading edge of bearings technology since their inception more than 120 years ago. During this time, Motion Australia and Schaeffler have enjoyed a distribution partnership since 1983—when Motion first began stocking Schaeffler bearings products and supplying them to Australian customers.  Tony has been working with Schaeffler’s bearings experts for so long that their team feels like close colleagues, he says. One of Tony’s liaisons, John Tawadros, Head of Distribution Sales at Schaeffler, concurs with this sentiment, explaining how the companies have found the partnership to be mutually beneficial over the years.  “When we find a good joint solutions-based partnership as we have with Motion Australia, it’s all about our combined capabilities,” says John. “As a bearing manufacturer and technology company, Schaeffler’s product expertise and engineering know-how supports Motion, our distribution partner, to develop joint strategies for presenting these solutions to customers.”

Bearing solutions for the world’s largest machines

Mining is an industry that is synonymous with giant machines. From bucket wheel reclaimers measuring tens of metres in diameter to kilometres-long conveyor lines carrying raw and processed material along, it is easy to feel like a lilliputian walking around a mining operation. To consider all those massive machineries rely on the humble bearings for rolling along puts the critical role of bearings into a fresh perspective. Over the decades, Schaeffler has built a reputation as manufacturer of large size industrial bearings, including being the first company to introduce split spherical roller bearings. Schaeffler’s FAG and INA large size bearings are mounted on various mining equipment across the world, from conveyor belt and pulleys to vibrating screens, vertical mills, roller presses and high-pressure grinding rollers (HPGRs).  In Australia, Schaeffler large size bearings are available through CBC’s national supply network. This, as Schaeffler Australia Engineering Manager Andreas Pieper elaborates, places Schaeffler in a unique position in terms of supply availability and responsiveness. Read More

How a ‘plug and play’ solution provides high-scale condition monitoring at minimal cost for miners

Condition monitoring has been a costly undertaking, and one that has required considerable time and resources to set up, especially in mine sites which are often remote and vast in scope. Moreover, condition monitoring requires specific expertise to interpret data so that it can be of actionable benefit to maintenance or reliability crews. This whitepaper addresses the challenges that mining operations face together with expert insights into a new condition monitoring solution called OPTIME. Additionally, it shows the benefits that have been realized from OPTIME through real case study examples.

Split bearings offer in situ replacement

Changing out a bearing stuck in between other components on a shaft can be quite challenging under normal conditions. But if this happens to be an emergency breakdown on a mine site, the task of replacing the bearing quickly is enough to give any site technician a headache.

Keeping those ball mills turning

When it comes to the mechanical components of ball mills – which are essential to any hard rock mining operation – the focus is often on the trunnion bearings. But it’s actually the pinion bearings, which are responsible for turning the ball mill around, that work the hardest.
