It can take as little as 30 minutes to replace a split roller bearing and even less time to inspect it; whereas solid bearings routinely take many hours, and sometimes days to replace and are notoriously difficult to inspect while in place. Yet overwhelmingly solid bearings comprise the major segment of rolling bearings in use in extraction industries today. Adrian Menzies, Sales Director of Revolvo Ltd., explains why the lowest cost bearing solution for the OEM is usually the most expensive for the quarry end-user.
Solid roller bearings are difficult to fit & to replace, and usually impossible to visually inspect whilst in service - relying instead on complex and expensive vibration monitoring systems for critical units. But, with the smaller sizes in particular, they are relatively inexpensive to purchase so few companies compare the overall lifetime costs with those of alternatives - such as split roller bearings (SRBs). In an industry that is driven by cost down pressures rectifying this situation could potentially lead to large savings in maintenance and plant downtime.
Companies are increasingly embracing the fact that to achieve performance gains they must first achieve improved production efficiencies. To achieve these longer term efficiencies it may be more cost effective to specify components that initially cost a little more, but will reduce maintenance and repair costs during their service life, therefore offering the customer a lower
