The Bosch Rexroth B.RUNNER BLOCK NR KWD-020-SNS-C0-H-1 (R201189330) is a high-precision ball runner block designed for linear motion applications requiring corrosion resistance and accuracy. This runner block is part of the Ball Rail Systems and features a slimline width (SNS format), normal length, and standard height. The body of the runner block is made from corrosion-resistant steel in accordance with DIN EN standards, ensuring durability and longevity even in harsh environments. With an accuracy class of H (high) and a preload class of C (preload-free), this model offers smooth motion without any preload-induced friction. It lacks a ball chain, which simplifies the design while maintaining performance. Initial lubrication and preservation have been applied to the runner block to reduce maintenance needs, with long-term lubrication potential extending over several years. The B.RUNNER BLOCK NR KWD-020-SNS-C0-H-1 has dynamic load capacities that are based on a 100 km travel as per DIN ISO standards, providing reliable performance under various load conditions. Its design allows for interchangeability with guide rails of every accuracy level, facilitating flexibility in assembly and replacement. In terms of sealing, this model comes with standard seals that effectively prevent contaminants from entering the block's interior, thus preserving its service life. Additionally, it features a straight lube connection loosely attached for ease of maintenance. This ball runner block is particularly suitable for applications where space is limited in the transverse direction but where maximum precision is required. Its excellent dynamic characteristics make it capable of handling high torque loads efficiently while maintaining low frictional oscillations even under external loads. It can be used on all SNS/SNO ball guide rails provided by Bosch Rexroth and supports high load ratings in all four main loading directions. This model does not come with attachment elements on either front reference edge but allows attachments to be mounted from above if needed.
