The Bosch Rexroth R162341820 is a size 45 SLS type steel standard ball bearing slider. The slider has a total width of 86mm, a total length of 174.1mm, and a total height of 60mm, and is compatible with size 45 guide rails. The R162341820 narrow, long, standard-height slider is suitable for linear motion applications where space is limited but high loads must be supported.
KWD-045-SLS-C0-N-1 is the complete code for all parameters of the R162341820 slider. 20 represents the size specification, SLS indicates that the slider is a narrow and long slider structure (high rigidity, saving lateral space), C1 indicates a light preload level, and X indicates an ultra-precision level.
The core features of the REXROTH SLS R162341820 long standard height ball bearing slider are as follows:
Compact Design: Ultra-thin and long structure, highly adaptable to scenarios with limited lateral installation space.
Omnidirectional Equal Load: Consistent load-bearing capacity in all four main load directions, excellent high torque capacity and torsional rigidity.
High Precision and Interchangeability: X precision class; sliders and guides within the same precision class can be arbitrarily combined, offering unlimited interchangeability.
Low Noise and Smooth Operation: Low operating noise, excellent rolling characteristics, built-in standard seal, pre-filled lithium-based grease, and convenient maintenance.
Due to its high rigidity, high precision, and high load-bearing capacity, R162349422 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
