The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FNS-C3-X-1 (R165123820) is a high-precision ball runner block designed for linear motion applications requiring exceptional rigidity and accuracy. This component is part of the Ball Rail Systems product group, offering excellent dynamic characteristics and significantly reduced frictional oscillations. It features a size 25 steel CS runner block body with a flanged width, normal length, and standard height without a ball chain. The B.RUNNER BLOCK CS is distinguished by its high preload class C and extra precision accuracy class XP. The runner block body comes with initial lubrication using Roller bearing grease Dynalub, ensuring long-term performance without the need for frequent maintenance. It allows for attachments to be mounted from both above and below, providing flexibility in system design. The product includes lube fittings with metal threads on all sides, an end-face fastening thread for attachments, and integrated all-around sealing to protect against contaminants. One of the key capabilities of this runner block is its high torque load capacity coupled with different preload classes to suit various application needs. The design also boasts improved rigidity under lift-off and side loading conditions due to additional mounting screw holes at the center of the block. For systems requiring maximum rigidity, the preloaded O-arrangement ensures optimal performance. An optional feature available with this model is an integrated, inductive, and wear-free measuring system for precise tracking of movement. The B.RUNNER BLOCK CS can be used on all SNS/SNO ball guide rails offered by Bosch Rexroth and supports long-term lubrication over several years without degradation. The R165123820 model's dimensions include an overall length of the runner block at . mm and a height of . mm when combined with a guide rail. Its dynamic load capacity C and static longitudinal moment load capacity ML are based on industry standards per DIN ISO 14728-1. Designed to handle maximum accelerations and permissible ambient temperatures ranging from min ... max °C (for short periods), this ball runner block is suitable for various demanding linear motion applications where precision and durability are paramount.
