The Bosch Rexroth B.RUNN. BLOCK NRII KWD-035-FNS-C0-H-0 (R200139305) is a high-precision, corrosion-resistant ball runner block designed for use in demanding linear motion applications. The runner block body and all steel components are constructed from corrosion-resistant steel according to DIN EN standards, ensuring durability and long-term performance even in harsh environments. This model features a size 35 flange width, normal length, and standard height, with an overall length of the runner block being 90 mm. With a preload class C0 indicating that it is preload-free and an accuracy class H for high precision, this ball runner block is engineered to deliver exceptional accuracy without any initial lubrication or preservation. It lacks a ball chain and attachment elements on both left and right front reference edges, facilitating straightforward installation. The B.RUNN. BLOCK NRII boasts excellent dynamic characteristics due to its patented entry zone that increases travel accuracy up to six times. This feature also allows for the use of this runner block with all SNS ball guide rails across five common sizes. The optimized entry zone geometry coupled with a high number of balls reduces variation in elastic deflection, contributing to the unit's impressive dynamic load capacity and static torsional moment load capacity. Designed for applications requiring high rigidity, this model can maintain long-term lubrication over several years and offers maximum precision. The lube fittings come with metal threads on all sides for convenience. Moreover, it has the same high load ratings in all four main directions of loading. This Bosch Rexroth ball runner block is versatile enough to be used in a variety of settings requiring precise linear movement such as automation systems, machine tooling, and packaging equipment. Its robust design ensures reliable performance under substantial loads while maintaining smooth motion control.
