The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FKS-C1-N-1 (R166521421) is a ball runner block designed for precision and performance in linear motion applications. This component features a size 25 flange, a short length, and standard height format FKS, with the runner block body constructed from unalloyed steel CS. It is engineered to provide low preload with a preload class C and offers standard accuracy with an accuracy class N. The runner block is not equipped with a ball chain but comes with initial lubrication and preservation using Roller bearing grease Dynalub. It allows for attachments to be mounted from both above and below without the need for an attachment element at either front reference edge. The straight lube connection is provided loosely attached, facilitating easy maintenance. With an overall length of the runner block specified in the product details, this component boasts interchangeability features, allowing it to be combined with guide rails of every accuracy level. The design significantly reduces frictional oscillations and maintains a low friction force level, especially under external load conditions. This Bosch Rexroth runner block is self-aligning to compensate for any misalignments and ensures maximum precision due to its patented entry zone that increases travel accuracy by up to six times. The unit supports long-term lubrication over several years and includes lube fittings with metal threads on all sides for convenience. High torque load capacity, various preload classes, high rigidity in all load directions allowing use of just one runner block per rail, and high load ratings in all four main loading directions are some of its prominent features. Additionally, it offers maximum system rigidity thanks to its preloaded O-arrangement and has optional integrated measuring systems available. The dynamic characteristics of this product are excellent, making it suitable for use on all SN/SNO ball guide rails by Bosch Rexroth. With its integrated all-around sealing system and various seal options available such as standard seal SS, low-friction seal LS, double-lip seal DS, front seal, FKM seal, and cover plate wiper – this ball runner block ensures durability even in challenging environments.
