The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-FNS-C1-X-1 (R165181820) is a state-of-the-art ball runner block designed for precision linear movement and high load capacity. This runner block features size 20 with an FNS format, indicating a flanged width, normal length, and standard height. It's constructed from unalloyed steel CS for durability and has a low preload class C, denoting minimal pre-tension on the ball bearings for smooth motion. Its accuracy class XP represents extra precision, ensuring superior travel accuracy for sensitive applications. Notably absent is the ball chain; instead, this model comes with initial lubrication and preservation using Roller bearing grease Dynalub to ensure long-term performance without immediate maintenance. The runner block body is of a standard version with straight lube connections that are loosely attached for ease of maintenance. The B.RUNNER BLOCK CS demonstrates excellent dynamic characteristics with reduced frictional oscillations and low friction force levels, especially under external loads. Its patented entry zone significantly improves travel accuracy by up to six times compared to conventional designs. The device allows attachments to be mounted from both above and below, providing flexibility in system design. It also features integrated all-around sealing and high torque load capacity. This model is highly versatile due to its interchangeable nature with guide rails of every accuracy level and its ability to meet high rigidity requirements even when using just one runner block per rail. Additional features include optional integrated inductive measuring systems and factory pre-lubrication for out-of-the-box operation. The B.RUNNER BLOCK CS is suitable for use on all SN/SNO ball guide rails by Bosch Rexroth, offering the potential for long-term lubrication over several years without compromising performance. This runner block can withstand high load ratings in all four main directions of loading due to its robust construction and design optimizations which improve rigidity under various loading conditions.
