The Bosch Rexroth B.RUNNER BLOCK CS KWD-045-FNS-C1-N-2 (R165141424) is a high-performance ball runner block designed for linear guidance and motion. This product is part of Bosch Rexroth's Ball Rail Systems, which are engineered to provide precise and smooth linear movement in a variety of applications. The design features four rows of balls with point contact, ensuring minimal friction in all loading directions, which enhances the system's efficiency and reduces heat generation compared to other systems with higher friction coefficients. Constructed according to DIN standards, the R165141424 offers a robust selection of materials and is designed to accommodate various attachments from above or below. It includes lube fittings with metal threads on all sides, end-face fastening threads for attachments, and integrated all-around sealing. This model boasts high torque capacity and different preload classes, contributing to its high rigidity in all load directions which allows for applications using just one runner block per rail. Furthermore, the ball chain and seals are meticulously designed for durability; standard universal seals (SS), low-friction seals (LS), double-lip seals (DS), front seals, FKM seals, and cover plate wipers are available to protect against contaminants like dirt, chips, coolants, or cutting fluids. These components are interchangeable during servicing, enhancing the longevity and maintenance ease of the ball runner block. The B.RUNNER BLOCK CS KWD-045-FNS-C1-N-2 also offers improved rigidity under liftoff and side loading conditions due to additional mounting screw holes at the center of the block. Maximum system rigidity is achieved through a pretensioned O-arrangement. An optional integrated inductive measuring system provides wear-free operation for precise applications. Pre-lubricated at the factory for immediate use on all SN/SNO Ball Guide Rails, this model enables long-term lubrication over several years without requiring frequent maintenance. It maintains high load ratings in all four main loading directions ensuring reliable performance across a wide range of industrial applications.
