The Bosch Rexroth B.RUNNER BLOCK CS KWE-025-FLS-C0-N-1 (R205B29420) is a high-performance linear motion component designed for precision and rigidity in various applications. This BSCL ball runner block has a size designation of 025 and features a flanged, long, standard height (FLS) format. Constructed from unalloyed steel CS, the runner block body ensures durability and consistent performance. The B.RUNNER BLOCK CS boasts an accuracy class N, indicating standard precision levels suitable for a wide range of uses. It comes with initial lubrication and preservation for immediate use and reduced maintenance requirements. Notably, this model is supplied without preload clearance (preload class C), which means it is designed to operate with minimal axial play, enhancing system accuracy. With an overall length of . mm, this runner block can be used interchangeably with guide rails of every accuracy class within its series. Its design caters to high rigidity demands and can handle very high load capacities, making it ideal for applications requiring robust linear guidance systems. The product's dynamic load capacity C , dynamic longitudinal moment load capacity ML , maximum permissible linear speed vmax , and static load rating C are indicative of its capability to handle demanding operational conditions. It also operates efficiently within a permissible ambient temperature range of min ... max °C. Additional features include the absence of a ball chain as standard, further simplifying the design. The Bosch Rexroth B.RUNNER BLOCK CS KWE-025-FLS-C0-N-1 is compatible with size T profiled rail systems for mounting from above or below, ensuring versatility in installation options. Overall, this runner block unit is engineered to provide reliable linear motion solutions in applications where precision movement and high-load capacity are essential. Its construction quality and performance specifications make it a valuable component in sophisticated mechanical systems.
