The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-SLH-C1-N-1 (R162421420) is a ball runner block designed for precision linear movement and rigidity in various applications. This model is part of the Ball Rail Systems product group and features a slimline, long, high (SLH) format, making it suitable for situations with limited space in the transverse direction but high rigidity requirements. The runner block body is constructed from carbon steel CS, ensuring durability and strength. This runner block boasts a low preload class C and standard accuracy class N. It comes without a ball chain but includes initial lubrication and preservation for reduced maintenance needs. The roller bearing grease Dynalub enhances performance and longevity. With an overall length of . mm, this model is designed without attachment elements on the left or right front reference edges and includes a straight lube connection that's loosely attached. One of the key features of this product is its high rigidity in all load directions, which allows for the use of just one runner block per rail in certain applications. It also offers high torque load capacity and limitless interchangeability within each accuracy class across all Ball Rail Systems and Ball Runner Block versions. The patented entry zone significantly improves travel accuracy. The B.RUNNER BLOCK CS KWD-025-SLH-C1-N-1 is prelubricated at the factory for convenience and supports long-term lubrication over several years. It has been engineered for smooth, quiet operation with an optimized ball return and guidance system. Additionally, it can accommodate various preload classes to meet specific application needs. Dynamic characteristics are excellent due to the four rows of balls providing point contact in all loading directions, minimizing friction even under external loads. Seals such as standard seal SS, low-friction seal LS, double-lip seal DS, front seal, FKM seal, and cover plate wiper are available to protect against contaminants that could reduce service life. Overall, this Bosch Rexroth ball runner block is well-suited for applications requiring maximum precision, minimal friction oscillations, high rigidity, torque capacity, and longevity in challenging environments.
