The Bosch Rexroth R162423820 is an SLH type (narrow, long, tall) ball slide in a ball guide system. This R1624 ball slide is commonly used in applications where lateral space is limited and high rigidity is required.
KWD-025-SLH-C3-X-1 is the complete code for the parameters of the R162423820 slide. 25 represents the size specification, SLH indicates that the slide is a narrow, long, tall slide structure (high rigidity, saving lateral space), C3 indicates height preload, and X indicates the extra precision accuracy class.
Rexroth R162423820 Ball Slider Key Performance Advantages
High Rigidity Design: The R162423820 SLH slider's elongated structure provides a larger contact area, and its height enhances vertical rigidity, making it suitable for high torque and complex loads.
Precision Motion Performance: Patented inlet zone geometry improves motion accuracy to 6 times that of ordinary designs, significantly reducing frictional oscillations.
Low Friction Characteristics: The ball circulation system achieves slip-free linear displacement, with a low coefficient of friction, smooth motion, and low energy consumption.
Modular Design: Facilitates on-site assembly, subsequent maintenance, and equipment upgrades.
Due to its high load-bearing capacity, high rigidity, and narrow dimensions, the R162422220 is widely used in the following precision manufacturing fields:
Precision feed axes of CNC machine tools and metal processing centers
Industrial robots and automated robotic arms
Semiconductor manufacturing and lithium battery assembly lines
Precision medical testing equipment and heavy-duty precision multi-axis positioning platforms
