The Bosch Rexroth B.RUNNER BLOCK CR KWD-020-BNS-C0-H-1 (R16715937Y) is a high-precision ball runner block designed for linear motion applications requiring corrosion resistance and high load capacity. This model features a Resist CR coating for enhanced durability and a size that is wide, normal in length, and standard in height. The body of the runner block is constructed from unalloyed steel CS with a matte-silver, hard chrome-plated finish. With an accuracy class of H for high precision and a preload class C indicating preload-free operation, this ball runner block ensures smooth motion without excessive play. It includes a ball chain to facilitate quiet and optimal travel behavior, as well as initial lubrication and preservation for maintenance-free operation upon delivery. Notably, the B.RUNNER BLOCK CR has an overall length of . mm and is capable of handling high torsional moments on rails. It offers excellent dynamic characteristics with the same high load ratings in all four main directions, contributing to its versatility across various applications. The product also features optimized entry-zone geometry for reduced elastic deflection variation and can be used on all BNS ball guide rails. The design includes end-face fastening threads for attachments above or below the block, two additional mounting screw holes at the center for improved rigidity under lift-off and side loading conditions, and a straight lube connection loosely attached. This runner block boasts very high torsional moment load capacity along with significant resistance to torsion, making it ideal as an individual guide in demanding environments. It operates within an ambient temperature range from min ... max °C (for short durations) and has been prelubricated at the factory to ensure optimal performance from day one.
