The Rexroth R166519420 is a high-performance, high-precision ball linear guide (BSHP series), officially designated KWD-015-FKS-C0-N-1. The R166519420 is a short-flange, standard-height ball linear guide slider, primarily used in high-precision automation and machine tool equipment with limited longitudinal installation space.
Key Features of the R166519420 Ball Linear Guide:
Space Optimization: Its short design is specifically tailored for automation structures with limited longitudinal installation space.
High Precision and Stability: Utilizing Bosch Rexroth's patented ball inlet area design, it improves smooth operation and significantly reduces friction fluctuations under external loads.
Two-Way Installation: The flange slider supports bolt fixing from either top or bottom, offering extremely high installation flexibility.
Excellent Interchangeability: Rexroth sliders and guideways are interchangeable, facilitating subsequent maintenance and parts replacement.
