The REXROTH R162342822 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-035-SLS-C2-X-1 is the complete code for all parameters of the R162342822 slider. 35 represents the size specification, SLS indicates that the slider is a narrow and long slider structure (high rigidity, saving lateral space), C2 indicates medium preload, and X indicates a higher precision level.
Key features of the REXROTH SLS R1623 ball slide include:
Narrow design, saving installation space: The SLS slide has a narrow lateral width, suitable for applications with limited internal space, while maintaining a longer slide length to increase load-bearing capacity.
Four-row ball design, equal load in four directions: Utilizing a four-row ball design with a 45° contact angle, it can withstand the same rated load in all four main directions (up, down, left, and right), providing high rigidity and balanced force distribution.
High precision and high repeatability: Available in N/H/P/XP precision grades to meet the needs of precision equipment, high-speed motion platforms, CNC applications, etc.
Interchangeable guide rails and slides: Within the same precision grade, slides and guide rails can be freely combined, facilitating maintenance and simplifying spare parts management.
Due to its high rigidity, high precision, and high load-bearing capacity, R162342822 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
