The Bosch Rexroth R162379320 is a high-performance ball rail slider, with the full model code KWD-030-SLS-C0-H-1. The R162379320 SLS narrow ball slider belongs to Rexroth's Ball Rail Systems, is made of carbon steel (CS), and is designed for compact spaces and high-load requirements.
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 R162379320 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.
