FAQ

What size guide rail is compatible with the R044281201 runner block?

This is a size 15 runner block and must be used with a corresponding Bosch Rexroth size 15 miniature guide rail (e.g., R0445 series).

C1 indicates a standard preload, which is approximately 2% of the dynamic load capacity (C). This provides a good balance between rigidity and low friction for general-purpose applications.

No. While Rexroth runner blocks are shipped with a corrosion preventative, they require initial lubrication with a suitable grease or oil before being put into service to ensure correct performance and service life.
