The Bosch Rexroth R162421220 is an SLH type (narrow, extended, tall) carbon steel ball slide block, belonging to the Rexroth ball guide system. This model features high rigidity, high torque capacity, and extremely high running accuracy.
Features of the Bosch Rexroth R162421220 ball slide block:
High-precision operation: Utilizing an H-class high-precision design, it runs smoothly, meeting the requirements for precise positioning and high repeatability.
High-rigidity structure: It possesses high rigidity in all force directions, allowing for single-slide load bearing in some applications.
Smooth operation: Optimized ball circulation and guide structure ensure smoother and more stable slide movement.
Long-life lubrication: Pre-lubricated at the factory, allowing for years of continuous lubrication and reducing maintenance frequency.
High interchangeability: It can be freely combined with Rexroth SNS/SNO series guideways, facilitating installation and replacement.
Suitable for confined spaces: The SLH narrow, long slider structure is suitable for horizontally installed equipment with limited space.
