The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FNS-C2-X-1 (R165122820) is a high-precision ball runner block designed for linear motion applications requiring extreme accuracy and rigidity. This runner block features a size 25 flange width, normal length, and standard height with an overall length of . mm. The body is constructed from unalloyed steel CS and comes with medium preload (class C) and extra precision accuracy (class XP), ensuring superior performance in demanding situations. The product does not include a ball chain but arrives with initial lubrication and preservation, utilizing the Roller bearing grease Dynalub for reduced maintenance needs. It boasts a straight lube connection that is loosely attached, allowing for easy maintenance access. Notably, the runner block can be combined with guide rails of every accuracy level, making it versatile for various applications. Its design features include an endface fastening thread for attachments and integrated all-around sealing to protect against contaminants. The runner block can accommodate high torque loads and offers different preload classes to suit specific application requirements. It has been engineered to provide high rigidity in all loading directions, which enables the use of just one runner block per rail in certain cases. Additional enhancements include improved rigidity under lift-off and side loading conditions thanks to two extra mounting screw holes at the center of the block. For maximum system rigidity, it employs a preloaded O-arrangement. The B.RUNNER BLOCK CS KWD-025-FNS-C2-X-1 is also compatible with an optional integrated, inductive measuring system for wear-free operation. This ball runner block is prelubricated at the factory and can be used on all SN/SNO ball guide rails by Bosch Rexroth. Its design assures long-term lubrication over several years without needing frequent maintenance. It can withstand high load ratings in all main directions of loading and operates within a permissible ambient temperature range from min ... max °C (admissible for short time). The dynamic load capacity C and dynamic torsional moment load capacity Mt are determined based on DIN ISO standards. In summary, this Bosch Rexroth ball runner block is engineered for applications where maximum precision, rigidity, and long service life are essential. Its robust construction and advanced sealing options ensure reliable operation even in harsh environments or when exposed to contaminants such as dirt or metal particles.
