FAQ

What type of lubrication is recommended for the R162282320 runner block?

Bosch Rexroth recommends using a lithium-based grease of consistency class NLGI 2, such as Rexroth Dynalub 510 or an equivalent, for optimal performance and longevity.

How do I properly install this runner block onto a Rexroth guide rail without losing the ball bearings?

The runner block is supplied with a plastic mounting arbor that keeps the balls in place. Slide the block directly from this arbor onto the cleaned and lightly oiled guide rail to ensure no balls are lost during installation.

What is the difference between preload class C2 (High Preload) and other classes like C0 or C1?

Preload class C2 indicates a high preload, which eliminates clearance in the bearing system for maximum rigidity and accuracy. This is crucial for applications like machine tools. C1 (light preload) and C0 (no preload) are used where lower friction is more important than absolute rigidity.
