The Bosch Rexroth B.RUNNER BLOCK NR KWD-035-FKS-C1-H-1 (R200031330) is a highly precise and corrosion-resistant ball runner block designed for linear motion applications. This component is made from Resist NR, a material that ensures durability and resistance to corrosive elements, complying with DIN EN standards. The runner block features a flanged width, short length, and standard height, making it suitable for applications with limited space in the longitudinal direction. It offers low preload (Preload class C) and high accuracy (Accuracy class H), without the inclusion of a ball chain to facilitate smooth movement. The block is initially lubricated and preserved to enhance its longevity and performance. With an overall length of . mm, this runner block supports interchangeability with guide rails across various accuracy classes. The B.RUNNER BLOCK NR KWD-035-FKS-C1-H-1 boasts excellent dynamic characteristics such as reduced frictional oscillations and low friction force levels, even under external load conditions. It is capable of long-term lubrication over several years without the need for maintenance. The patented entry zone increases travel accuracy significantly—up to six times—making it ideal for precision-demanding tasks. This model can be used with all SN/SNO ball guide rails by Bosch Rexroth, carrying high load ratings in all four main loading directions. It comes pre-lubricated from the factory for immediate use and has a permissible ambient temperature range from min ... max °C for short durations. In terms of load capacities, the dynamic load capacity C and dynamic torsional moment load capacity Mt are determined based on a 100 km travel as per DIN ISO standards; however, it is often only 50 km that are actually stipulated. For comparison purposes, values can be multiplied by .6. The B.RUNNER BLOCK NR KWD-035-FKS-C1-H-1 also features various sealing options like the standard seal SS for universal protection or specialized seals such as LS (low-friction seal), DS (double-lip seal), front seals, FKM seals, and cover plate wipers available as accessories for different environmental conditions or servicing needs. Attachments on the runner block can be mounted from above or below to accommodate various mounting configurations.
