R162371820 SLS Ball Runner Block REXROTH Long Slider Linear Block

The Bosch Rexroth KWD-030-SLS-C1-X-1 (R162371820) is a 30mm ultra-thin (SLS) carbon steel ball bearing housing designed for high-precision linear motion. Featuring standard height, long length, higher precision (XP), and low preload (C1), it is ideal for heavy-duty applications requiring smooth motion.

SLS sliders refer to ball sliders with SLS (Slimline, Long, Standard-height) structural features. They belong to high-precision, high-speed guide rail systems and are characterized by their narrow width, long length, and standard height, making them widely applicable in mechanical applications where lateral space is limited.

The core features of the R162371820 high-precision slider are:

It employs a four-row ball bearing structure, achieving equal load capacity in four directions, providing strong load-bearing capacity and the ability to withstand torque loads;

The SLS narrow and extended design maintains high rigidity and high load-bearing performance even in space-constrained conditions;

It supports both long-term lubrication and initial pre-lubrication designs, enabling years of low-maintenance operation;

The standard sealing structure provides excellent dustproof and contamination resistance;

The slider and guide rail are interchangeable within the same precision class, facilitating maintenance and replacement.
