REXROTH R162373820 KWD-030-SLS-C3-X-1 Carbon Steel Ball Runner Block

The R162373820 ball slider is a high-precision, high-rigidity ball slider from Bosch Rexroth's SLS series, model code KWD-030-FLS-C3-X-1. It is commonly used in linear motion systems with stringent requirements for positioning accuracy and load capacity. The narrow, long ball slider R162373820 features a high preload (C3) and extra precision (XP) design, with a CS steel body, providing high rigidity and high load capacity.
Key features of Rexroth SLS steel sliders:
① Utilizes a four-row ball bearing circulation structure, providing equal load capacity in four directions. It can simultaneously withstand radial, reverse, and lateral loads, offering excellent overall rigidity and load-bearing performance.
② The narrow, elongated design of the SLS slider effectively saves lateral installation space while ensuring high load capacity, making it suitable for compact equipment layouts.
③ The rolling friction structure ensures smooth operation and a low coefficient of friction, supporting high-speed (up to approximately 5 m/s) and high-acceleration conditions.
④ Ball bearing sliders can be equipped with a ball chain design, significantly reducing noise and wear, and improving service life and stability.
⑤ Factory pre-lubricated and supports long-term lubrication solutions, requiring minimal maintenance under optimal operating conditions.
⑥ Offers multiple preload and precision grades to flexibly match different application requirements in terms of rigidity, precision, and lifespan.
