The REXROTH R162349322 ball block belongs to the SLS series (narrow, long, standard height) high-load-bearing steel ball block from Bosch Rexroth, Germany. Its core advantage lies in its ability to withstand extremely high loads and torques in operating environments with limited lateral space, while maintaining the same ultra-high rated load in all four main force directions.
KWD-045-SLS-C0-H-1 is the complete code for all parameters of the R162349322 slider. 35 represents the size specification, SLS indicates that the slider is a narrow and long slider structure (high rigidity, saving lateral space), C0 indicates no preload, and H indicates high precision level.
Key Advantages of the R162349322 Slider:
High Torque Capacity: The extended SLS design provides a larger contact area, significantly improving resistance to torsional torque.
Low Noise Operation: Equipped with a ball chain (end code 22), the balls do not collide during circulation, resulting in quieter and smoother operation.
High Interchangeability: Rexroth sliders and guides can be combined arbitrarily within the same accuracy class, making maintenance and replacement very convenient.
Multi-directional Load Capacity: Offers the same rated load capacity in all four main load directions.
Due to its high rigidity, high precision, and high load-bearing capacity, R162349322 ball bearing slides are mainly used in the following industrial automation and machinery manufacturing industries:
1. CNC machine tools and metal processing industry
2. Laser technology and advanced manufacturing
3. Semiconductor, electronics, and microelectronics industry
4. Industrial robots and automated production lines
5. Precision measuring and testing instruments
6. Woodworking and plastics processing machinery
