The ball rail systems BSHP and ball screw assemblies BASA from Bosch Rexroth now achieve lubrication intervals that are up to four times longer. In more and more applications, they can even be used maintenance-free over the entire service life of a component. As a result, low-maintenance or maintenance-free linear motion technology minimizes operating costs and also protects the environment because less lubricant is required.

The results of the most recent tests show that the lubrication intervals for Rexroth’s ball rail systems BSHP are twice as long as they were before. The runner blocks can cover up to 20,000 km before the first relubrication, the same distance as from Germany to New Zealand.

Bosch Rexroth’s latest generation of ball screw assemblies BASA achieves up to 200 million revolutions with the basic factory lubrication. In this case, the intervals are as much as four times higher. The balls on the screw cover a distance of around 12,800 km
