Rexroth Delivers High-Precision Ball Rail System

The High-Precision Ball Rail linear guide system from Bosch Rexroth Corporation takes the science of linear motion forward by reducing rolling, pitching and yawing deviations in linear guideways due to ball recirculation. The result is smooth motion with virtually no deviation in the X, Y or Z direction. The system is suitable for high-end machining, measuring and scanning devices requiring ultra-precise movement. The super-high precision performance is achieved via technological enhancements to the bearing raceway geometry to minimize ball pulsations and reduce the influence of guideway bolts on the running smoothness of the runner block. Rexroth now includes High-precision Ball Rail technology as a standard in SP and UP accuracies as well as the completely new XP accuracy class. The blocks can be run on standard Rexroth rails, or for additional accuracy and smoothness, on special high-precision rails. The High-precision Ball Rail System is available in preloaded sizes 15-45, with or without ball chain technology. Single piece rail lengths up to six meters are available.
