The Bosch Rexroth B.RUNNER BLOCK CR KWD-020-CNS-C0-H-1 (R16725937Z) is a highly precise ball runner block designed for linear motion applications requiring high accuracy and corrosion resistance. This runner block features a Resist CR coating, which provides exceptional durability in corrosive environments. It is built to accommodate high torsional moments on rails with limited lateral space and offers the same high load ratings in all four main load directions. Its dynamic characteristics are enhanced by an optimized entry-zone geometry and a large number of balls, which reduce variation in elastic deflection. The B.RUNNER BLOCK CR is made from unalloyed steel CS with a matte-silver finish that is hard chrome plated, ensuring long-term reliability and performance. It comes preload-free (Preload class C) and boasts a high level of accuracy (Accuracy class H), but does not include a ball chain. The product is supplied with initial lubrication and preservation, using roller bearing grease Dynalub for smooth operation right out of the box. With dimensions tailored for compact width (CNS), normal length, and standard height, the runner block body has an overall length of . mm. It can be combined with any BNS ball guide rails to achieve maximum system rigidity through preloaded O-arrangement configurations. For attachments, there are options for mounting from above and end-face fastening threads without attachment elements on the left or right front reference edges. This runner block also includes two additional mounting screw holes at the center to improve rigidity under liftoff and side loading conditions. It operates within an ambient temperature range from min ... max °C for short periods while maintaining its dynamic load capacity C as per DIN ISO standards. The B.RUNNER BLOCK CR KWD-020-CNS-C0-H-1 is an ideal solution for applications demanding high precision linear guidance with excellent resistance to torsion and corrosion.
