The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-SNH-C0-N-1 (R162129420) is a ball runner block designed for high precision and rigidity in linear motion applications. This runner block is part of the Ball Rail Systems product group, suitable for various industrial applications requiring accurate and smooth linear movement. With a slimline width, normal length, and high height format (SNH), it is particularly well-suited for restricted spaces in the transverse direction while maintaining high rigidity requirements. The B.RUNNER BLOCK CS KWD-025-SNH-C0-N-1 features an unalloyed steel CS body with a standard accuracy class N and is preload-free (preload class C). It comes without a ball chain, ensuring ease of installation and maintenance. The unit has been initially lubricated and preserved to ensure long-term performance with minimal maintenance needs. Featuring a straight lube connection that is loosely attached, this runner block has an overall length of . mm. It showcases interchangeability within each accuracy class across all Bosch Rexroth Ball Rail Systems, allowing for flexibility in system design. The patented entry zone design significantly enhances travel accuracy—up to six times—especially under external load conditions. This model boasts a high dynamic load capacity (C) and can accommodate maximum permissible linear speeds (vmax). It also supports different preload classes, offering excellent dynamic characteristics suitable for diverse operational demands. The friction coefficient ranges from . to ., contributing to reduced frictional oscillations and low friction force levels. For durability and protection against contaminants, various seal options are available such as the standard seal SS, low-friction seal LS, double-lip seal DS, front seal, FKM seal for extreme environments, and cover plate wiper for coarse dirt or chips. These seals enhance the service life of the runner block by shielding it from dirt, chips, coolants, or cutting fluids. Overall, the Bosch Rexroth B.RUNNER BLOCK CS KWD-025-SNH-C0-N-1 offers high rigidity across all load directions allowing for single runner block applications per rail if needed. Its design ensures smooth operation with excellent dynamic properties while remaining interchangeable with other components within its class for versatile application use.
