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). What does the preload class ‘C1’ signify for this component?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. Can this runner block be used without initial lubrication?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. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
