R166581422 Ball Runner Block Carbon Steel KWD-020-FKS-C1-N-1

Rexroth R166581422 is a high-performance, high-precision ball slide (BSHP series), officially designated as KWD-020-FKS-C1-N-1. The R166581422 is a short-flange, standard-height linear guide ball slide, primarily used in high-precision automated and machine tool equipment where longitudinal installation space is limited.

Key features of the R166581422 (FKS) ball slide block:

Flange-short (FKS) construction: The slide block has a flange, providing good mounting rigidity and a small footprint, suitable for compact equipment designs.

Four-row ball circulation design: Utilizing a four-row ball contact design, it can achieve medium load capacity in radial, reverse radial, and lateral directions.

High-precision guidance: Smooth operation with high positioning accuracy and repeatability.

Equipped with sealing and lubrication system: Standard end face seal and optimized internal lubrication channels effectively prevent contaminant ingress and extend service life

Ball chain design: Low noise and smooth movement, suitable for automated equipment and precision machinery applications.
