R162431220 is a high-precision ball bearing slider from Bosch Rexroth (Germany). It belongs to the 35mm narrow, extended, high-rigidity linear guide slider series, primarily used in automated equipment and precision machine tools where lateral space is limited but rigidity and load-bearing capacity are extremely important.
Key Features of the SLH Type Carbon Steel Ball Slider R162431220 :
Ultra-High Load Capacity and Rigidity: Utilizing an extended design, it features more load-bearing balls than standard sliders, resulting in significantly higher rigidity than standard sliders like the SLS.
Slimline Design: Employing a slimline design specifically for mechanical structures with limited lateral installation space but extremely high load-bearing requirements.
Extremely Smooth Operation: Thanks to Rexroth's proprietary inlet zone geometry, it significantly reduces frictional vibrations under external loads, improving running accuracy by up to 6 times compared to conventional designs.
High-Quality Carbon Steel Body: The R162431220 slider body is made of high-strength carbon steel, offering excellent wear resistance and impact resistance, suitable for harsh industrial processing environments.
C1 Light Preload Configuration: The C1 preload configuration makes it primarily suitable for conventional precision drivelines, offering advantages such as minimal running resistance and high cost-effectiveness.
R162431220 is commonly used in industrial applications with stringent requirements for both space and rigidity:
Machine tools and machining centers
High-precision automated production lines, robotic arms and linear modules
Semiconductor manufacturing equipment and precision measuring instruments
