Rexroth creates a new star

Rexroth Star has launched the Generation 2000 Ball Rail System, said to show high load capacity, longer service life and extended service intervals.

A key development has been the intensive surface finishing of the ball track surface, to Ra values of around 0.1. This, claims Rexroth, has resulted in a 30% increase in dynamic load capacity or an extension of service life by a factor of 2.2.

The lubrication system has been improved so that for some operations no lubrication is needed at all, during the service life of the runner block.

Maintenance intervals have been extended by the lubricant being precisely applied to wet the surface area of each ball, by use of optimised seals and by a capacious lubricant reservoir.

Lubrication retention is said to be assisted by the optional ball retainer.The ball retainer is designed to achieve uniform load distribution together with very smooth running and low noise.
