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 - the same distance as from Germany to Hawaii.
The fact that the time span until relubrication is now longer for both product groups is due not only to the constant improvements to production processes, but also to Bosch Rexroth s innovative design. Thanks to their patented entry zone, the BSHP runner blocks achieve optimum precision, friction forces and friction force fluctuations. The ball screw assemblies BASA are designed to achieve particularly high
