The Bosch Rexroth B.RUNNER BLOCK CS KWD-020-BNS-C1-H-1 (R16715132Y) is a high-precision ball runner block designed for linear motion applications requiring high accuracy and low noise operation. This runner block belongs to the BNS size category, with a wide format, normal length, and standard height. It is constructed from unalloyed steel CS, ensuring robustness and longevity under various operating conditions. With a preload class of C, it offers low preload which facilitates smooth movement and reduced system strain. The accuracy class H indicates that this runner block operates with high precision. A notable feature of this model is the inclusion of a ball chain that contributes to its quiet and smooth travel behavior. This ball runner block is pre-lubricated with Dynalub grease for initial use and has provisions for long-term lubrication over several years. It has been designed without attachment elements on either front reference edge but includes a straight lube connection that is loosely attached. The overall length of the runner block is specified by the manufacturer. One of the key advantages of the B.RUNNER BLOCK CS KWD-020-BNS-C1-H-1 is its interchangeability with guide rails across various accuracies, offering versatility in application use. It boasts excellent dynamic characteristics suitable for situations involving high torsional moments on rails. Additionally, it can withstand high load ratings in all four main loading directions. The design also features integrated all-around sealing to protect against contaminants and ensure reliable operation in diverse environments. Its optimized entry-zone geometry along with a significant number of balls reduces elastic deflection variations, maximizing system rigidity due to its preloaded O-arrangement. Attachments can be mounted from above or below thanks to end-face fastening threads and lube connections with metal threads on all sides are provided for easy maintenance. The ball runner block's quiet operation is attributed to its well-designed ball return and guideway system which also allows for very high torsional moment load capacity and torsion resistance, making it an ideal choice as an individual guide in precision applications.
