The REXROTH R162372820 slider is a high-precision ball slider (size 30) for Bosch Rexroth ball guide systems, belonging to the SLS narrow carbon steel series. KWD-030-SLS-C2-X-1 is the complete code for the parameters of the R162372820 slider. 30 represents the size specification, SLS indicates a narrow, long slider structure (high rigidity, saving lateral space), C2 indicates a medium preload level, and X indicates a higher precision level.
Key Technical Features of SLS Ball Slider:
High Precision and High Speed: Designed for high-precision applications and capable of achieving very high linear speeds.
Narrow Design: Specifically designed for applications with limited lateral space, saving space.
Long Life and Low Friction: Utilizes an advanced sealing and lubrication system, significantly reducing friction fluctuations, making it particularly suitable for high-speed applications.
Multiple Materials: Available in carbon steel (CS) for general environments or corrosion-resistant steel (NR) for special applications.
Application Scenarios
Rexroth SLS sliders are commonly used in fields requiring high-speed, high-precision linear motion, such as automated machinery, machine tools, semiconductor manufacturing equipment, and packaging machinery.
