The Bosch Rexroth B.RUNNER BLOCK CS KWD-030-SNH-C1-H-1 (R162171322) is a high-precision ball runner block designed for linear motion applications requiring compact size, high rigidity, and accuracy. This runner block is part of the Ball Rail Systems product family and is characterized by a slimline width, normal length, and high height format (SNH). It is constructed from unalloyed steel CS with an accuracy class of H for high precision and a low preload class C. The runner block features a ball chain to ensure quiet and smooth operation with low noise levels and optimal travel behavior. This model comes prelubricated from the factory with roller bearing grease Dynalub, which allows for long-term lubrication spanning several years. The dynamic load capacity C and static longitudinal moment load capacity ML are determined as per DIN ISO standards. Designed with interchangeability in mind, this runner block can be combined with guide rails of varying accuracies without compatibility issues. The B.RUNNER BLOCK CS KWD-030-SNH-C1-H-1 boasts excellent dynamic characteristics such as reduced frictional oscillations and low friction force levels, especially under external loads. Its design facilitates applications that require only one runner block per rail due to its high rigidity in all load directions. Additionally, it has a high torque load capacity which makes it suitable for various demanding applications. Sealing options like 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 like dirt, chips, or coolants that can reduce service life. These seals help maintain the integrity of the ball runner block in diverse operating environments. The product's overall design focuses on achieving minimal friction while ensuring durability and performance consistency over time.
