The Bosch Rexroth B.RUNNER BLOCK NR KWD-020-SLS-C0-H-1 (R201289333) is a high-precision ball runner block designed for linear motion applications requiring corrosion resistance and high accuracy. This runner block is part of the Ball Rail Systems product line, specifically crafted to provide smooth and precise movement in a variety of applications. It features a slimline width, long length, and standard height format (SLS), with an overall length of 63 mm. The body of the runner block is made from corrosion-resistant steel conforming to DIN EN standards, ensuring durability and longevity even in harsh environments. It comes with a ball chain that reduces noise levels and enhances travel behavior, contributing to its excellent dynamic characteristics. The B.RUNNER BLOCK NR KWD-020-SLS-C0-H-1 is prelubricated at the factory with roller bearing grease Dynalub 510 for immediate use and offers long-term lubrication capabilities. With an accuracy class H (high) and preload class C (preload-free), this runner block delivers high precision without preload clearance. Its design allows for self-aligning to compensate for misalignments, ensuring reliable operation. The dynamic load capacity is specified by Bosch Rexroth standards based on a 100 km travel as per DIN ISO norms. This model also boasts high load ratings in all four main loading directions, including a static load rating C0 and dynamic torsional moment load capacity Mt. Attachments on the runner block can be mounted from above, providing flexibility in assembly. Compatible with all SN/SNO ball guide rails, the B.RUNNER BLOCK NR KWD-020-SLS-C0-H-1 can handle maximum accelerations and velocities as specified by Bosch Rexroth's comprehensive guidelines. Additionally, various 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 like dirt or metal particles and exposure to coolants or cutting fluids. These seals contribute significantly to maintaining the service life of the runner block under different environmental conditions.
