The 1666-214-20 is a star runner block bearing designed for use on the X axis, featuring two mounting holes. It is part of the STAR Ball Rail® systems, which are engineered for applications requiring compact and precise linear motion, such as machine tools and industrial robots. The system includes a highly precise ball runner block that can be mounted from above on the ball rail, making it suitable for restricted space environments in both longitudinal and transverse directions. This bearing is compatible with steel ball rails of size 25, offering moderate preload (2%) and standard accuracy class, and is ideal for high-precision linear movement in various industrial applications.
