The Bosch Rexroth B.RUNNER BLOCK CS KWD-030-FNS-C1-U-1 (R165171920) is a high-performance ball runner block designed for linear motion applications requiring superior precision and rigidity. This model features an ultra-precision accuracy class UP and a low preload class C, ensuring smooth motion with minimal frictional resistance. The runner block body is constructed from unalloyed steel CS, providing durability and strength for demanding applications. This particular runner block is part of the FNS series, which denotes a flange width, normal length, and standard height configuration. It does not include a ball chain but comes with initial lubrication and preservation for immediate use. The roller bearing grease Dynalub enhances the longevity of the component. The design incorporates straight lube connections that are loosely attached for ease of maintenance. With its overall length specified in the product information, the B.RUNNER BLOCK CS KWD-030-FNS-C1-U-1 offers interchangeability with guide rails across various accuracy levels, expanding its versatility across different setups. It is engineered to meet high rigidity requirements while delivering excellent dynamic characteristics such as reduced frictional oscillations even under external load conditions. Additional features include an integrated all-around sealing system to protect against contaminants, high torque load capacity, and multiple mounting options for attachments from above or below. The two additional mounting screw holes at the center enhance rigidity under liftoff and side loading conditions. For systems requiring precise measurement, an optional integrated inductive measuring system can be added. This ball runner block is pre-lubricated at the factory to enable long-term lubrication over several years without frequent maintenance. Capable of handling high load ratings in all four main directions of loading, it ensures maximum system rigidity due to its preloaded O-arrangement design. Suitable for use on all SN/SNO ball guide rails, this model stands out as a reliable component for sophisticated linear motion systems where precision and performance are critical.
