The Bosch Rexroth B.RUNNER BLOCK CS KWC-020-FNN-C1-H-2 (R169381311) is a high-precision ball runner block designed for linear motion applications requiring restricted upward space and maximum precision. This runner block features an FNN format, indicating a flange width, normal length, and low height profile. The body of the runner block is made from unalloyed steel CS, ensuring durability and strength. This model comes with a low preload (preload class C) and high accuracy class H, which contributes to its precise movement capabilities. Notably, it does not include a ball chain and is preserved without initial lubrication for flexibility in application-specific lubrication strategies. The angular lube nipples are loosely attached, allowing for easy maintenance. The B.RUNNER BLOCK CS has an overall length of . mm and offers interchangeability with guide rails of varying accuracies. Its patented entry zone increases travel accuracy by up to six times while reducing frictional oscillations and maintaining a low friction force level even under external loads. Long-term lubrication is possible over several years due to its design. Moreover, the runner block can handle high torque loads and offers optional features such as an integrated, inductive measuring system for wear-free operation. It supports attachments from both above and below the block for versatile mounting options. The integrated all-around sealing ensures protection against contaminants while maintaining ease of movement. With optimized entry zone geometry and a high number of balls, the runner block minimizes variation in elastic deflection. It can be used with all SN/SNO ball guide rails from Bosch Rexroth's product range. In summary, this Bosch Rexroth runner block is engineered for applications demanding high precision, low friction movements with reliable long-term performance.
