Contaminated environments in Quarrying & Mining Industries

NSK Bearings help reduce downtime from the effects of contaminated lubrication

Rolling bearings are key components in ensuring continuity of production in all areas of quarrying and extraction industries. In the dusty, grit and moisture- laden atmospheres encountered in quarries, bearings can fail prematurely due to contaminated lubricant. Where this problem is prevalent, no amount of maintenance will solve it. Instead, the solution lies with new bearing materials technology, in the shape of NSK’s Hi-TF and Super-TF bearing steels.

NSK bearings manufactured from Hi-TF and Super-TF steels are an answer to the problem of premature bearing failures resulting not only from contaminated, but also from insufficient lubricant. In comparison with bearings made of ordinary carburized steel, Hi-TF offers up to 7-times the life with contaminated lubricant, and up to 1.5 times the life with clean lubricant. Super-TF material improves on these figures by offering up to 10- times the life with contaminated lubrication and up to twice the life where the lubricant is clean. Where the problem is related to insufficient lubrication, the life of Super TF is still impressive at around 5.5 times (4.7 for Hi-TF) that of ordinary carburised steel.  

For advice on bearings manufactured from Hi-TF and Super TF steels, and all other NSK solutions for quarrying, please contact us. Our bearing substitution programme, backed up by training, and underpinned by with a wealth of technical expertise, delivers optimum bearing solutions for our customers, ensuring that they get the most from their plant and machinery
