Model R162441320 corresponds to the Rexroth KWD-045-SLH-C1-H-1 ball slide block. The KWD-045-SLH-C1-H-1 ball slide block belongs to the SLH series and is a standard steel slide block with a narrow, long, and high center of gravity design, suitable for applications with limited space but requiring high rigidity. Its specification is 45, and it is a high-precision (accuracy class H) ball slide block with light preload (preload class C1).
The main features of the Bosch Rexroth R162441320 steel ball bearing slider can be summarized as follows:
High load capacity: Utilizing a four-row ball bearing design, it boasts strong radial and reverse load capacity, suitable for heavy-duty applications;
High rigidity and stability: The elongated slider structure enhances torsional and vibration resistance, resulting in more stable operation;
High precision: Provides stable guiding accuracy, suitable for precision linear motion systems;
Long life and reliability: Optimized lubrication and raceway design extend service life and reduce maintenance frequency;
High versatility and interchangeability: Compatible with Rexroth guide rail systems of the same specifications, facilitating equipment upgrades and replacements.
Due to its high load-bearing capacity, high rigidity, and narrow dimensions, the R162441320 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
