Bosch Rexroth KWC-055-FNS-C1-N-2 Ball Runner Block Linear Guide

The Bosch Rexroth R165151410 KWC-055-FNS-C1-N-2 ball runner block is a flange-mounted, size 55 carrier for Rexroth SNS ball guide rails, designed for maximum speeds and maximum rigidity in all load directions. It features a carbon steel (CS) body, a low preload class (C1) with normal accuracy (N), and a weight of about 5.010 kg; its overall dimensions are 159.0 mm in length, 140 mm in width, and 57 mm in height (70 mm with the guide rail), with lubrication preserved but without initial lubrication. The block includes two central mounting holes to improve lift-off and side-loading rigidity, and attachments can be mounted from above or below via an end-face fastening thread; it is interchangeable with all SNS rail variants, enabling flexible system CONFIGURATION for high-rigidity applications. In addition, a 45-degree lubrication nipple arrangement is provided to support maintenance, and the assembly offers a dynamic load capacity of approximately 109 kN for demanding linear guidance.
