The Bosch Rexroth B.RUNNER BLOCK NR KWD-020-SLS-C0-H-1 (R201289330) is a high-precision ball runner block designed for linear motion applications requiring corrosion resistance and high accuracy. This model is part of the Ball Rail Systems product line, characterized by its slimline width, long length, and standard height format. The runner block body is crafted from corrosion-resistant steel in accordance with DIN standards, ensuring durability and longevity in challenging environments. With a preload class C, this runner block operates without preload clearance, contributing to its smooth motion. It falls under accuracy class H for highly accurate applications. Notably, it does not include a ball chain and comes with initial lubrication and preservation for immediate use upon installation. This model employs roller bearing grease Dynalub 510 for reliable performance. The B.RUNNER BLOCK NR features a straight lube connection that is loosely attached and an overall length of 104 mm. It offers interchangeability with guide rails across various accuracies, enhancing versatility in use. The patented entry zone increases travel accuracy by up to six times, while the design minimizes frictional oscillations and maintains low friction levels even under external load. This product can sustain long-term lubrication over several years and boasts excellent dynamic characteristics suitable for all SN/SNO ball guide rails. It has a high torque load capacity with consistent load ratings in all four main loading directions. For applications requiring specialized sealing against contaminants such as dirt, chips, or coolants, the B.RUNNER BLOCK NR accommodates various seal types including standard SS seals for effective protection and low friction operation. Additional seal options like LS (low-friction), DS (double-lip), FKM seals, front seals, and cover plate wipers are available as accessories for customization based on environmental conditions. In summary, the Bosch Rexroth B.RUNNER BLOCK NR KWD-020-SLS-C0-H-1 (R201289330) offers engineers a highly precise and corrosion-resistant solution for advanced linear motion systems where space is restricted in the transverse direction. Its robust design allows it to handle demanding applications while maintaining accuracy and efficiency over extended periods of operation.
