Precision rails with ball assemblies for industrial applications

Benefits

High precision and accuracy in motion
Space saving design
Smoothest running performance

Features

Precision available in small sizes
Lowest friction with no ball recirculation
Anti-creeping system ACSM option

Ewellix LWRB ball assemblies offer the lowest friction for precision rail guides where lighter loads are in motion. The ball design with ball retaining cages has the smallest built in dimensions and is optional available with Anti-Creeping System ACSM to avoid cage creeping during motion.
