The Bosch Rexroth B.RUNNER BLOCK NR KWD-030-FLS-C0-H-1 (R200279332) is a high-precision ball runner block designed for linear motion applications requiring corrosion resistance, high rigidity, and low friction. This model is part of the FLS series and features a flange width, long length, and standard height. The runner block body is constructed from corrosion-resistant steel in accordance with DIN standards, ensuring durability and longevity in harsh environments. With a preload class of C0, this runner block offers preload-free motion for applications where smooth movement is essential. It falls under accuracy class H for highly accurate positioning requirements. The inclusion of a ball chain minimizes noise levels and enhances travel behavior, while the initial factory lubrication ensures long-term performance with minimal maintenance. This model boasts an overall length of 90 mm and can be used interchangeably with all SN/SNO ball guide rails within each accuracy class, providing flexibility for various design configurations. It has been engineered to meet the most demanding rigidity specifications and to sustain high torque loads effectively. Additionally, the B.RUNNER BLOCK NR KWD-030-FLS-C0-H-1 accommodates attachments from both above and below the runner block. The patented entry zone increases travel accuracy significantly—up to six times—making it suitable for precision-critical applications. Its dynamic characteristics are enhanced by its ability to withstand liftoff and side loading conditions due to two extra mounting screw holes at its center. This Bosch Rexroth ball runner block is a reliable component that delivers excellent dynamic load capacity, static load rating, as well as dynamic and static torsional moment load capacities. It supports maximum accelerations and permissible linear speeds within specified temperature ranges (-10°C to +100°C), making it an adaptable choice for various industrial applications where precision linear movement is crucial.
