Prestressing of compression springs

Prestressing of compression springs

Most people who work with springs will be aware of the concept of prestressing, or at least the idea of a spring becoming shorter the first time it is used. However, the underlying mechanisms of why this occurs and the benefits beyond stabilising the dimensions of the spring are probably less well known…

The top five challenges of relubricating bearings

The top five challenges of relubricating bearings

A car owner's worst nightmare is accidentally filling their tank with diesel when their car runs on petrol. A fuel mix-up can be very damaging and costly, not to mention embarrassing. The same can be applied to being selective when designing machinery, particularly when choosing your bearings. Here, Chris Johnson, Managing Director of SMB Bearings, explains the top five challenges of relubricating bearings.

When to use a thin section bearing to boost performance?

It would be difficult to imagine how the modern industrial age would have developed without…bearings. Every kind of machine that requires motion makes use of bearings in some way, to smooth its path and reduce friction.
