The Bosch Rexroth R162172320 is a high-precision Ball Runner Block from the SNH series, designed for linear guide rail systems. Constructed from carbon steel, this runner block offers exceptional rigidity and a high load-bearing capacity, making it suitable for demanding applications in machine tools, industrial automation, and heavy-duty handling systems. Its flanged, normal length, high height design ensures robust and stable mounting. The C2 heavy preload class provides increased stiffness and resistance to deflection, while the H accuracy class guarantees precise and repeatable movement. This component is engineered for long service life and smooth, low-friction operation under significant dynamic and static loads.
