The Bosch Rexroth B.RUNNER BLOCK CS KWC-025-FNN-C1-H-2 (R169321310) is a highly precise ball runner block designed for linear motion applications requiring maximum precision and rigidity. This runner block is part of the Ball Rail Systems product group and features a size designation that corresponds to its specific dimensions. It comes in an FNN format, indicating a flange width, normal length, and low height design, suitable for applications with restricted upward space. Constructed from unalloyed steel CS, the runner block body ensures durability and performance. The preload class C indicates a low preload configuration which contributes to the smoothness of movement, while the accuracy class H denotes high precision. Notably, this model does not include a ball chain and arrives preserved but without initial lubrication. The product is designed with angular lube nipples loosely attached for ease of maintenance and offers an end-face fastening thread for various attachments. Its integrated all-around sealing provides protection against contaminants, thereby extending service life. The Bosch Rexroth B.RUNNER BLOCK CS supports high torque loads and can be used with all SN/SNO ball guide rails. Moreover, this model boasts an optimized entry zone geometry combined with a high number of balls to minimize variation in elastic deflection. This feature significantly reduces frictional oscillations and maintains a low friction force level even under external load conditions. Long-term lubrication over several years is possible due to its design. For those requiring an advanced measuring system, this runner block can be optionally equipped with an integrated, inductive, wear-free measuring system. Attachments can be mounted from both above and below the runner block for flexibility in installation. In summary, the Bosch Rexroth B.RUNNER BLOCK CS KWC-025-FNN-C1-H-2 (R169321310) represents a versatile solution for linear motion systems demanding high accuracy and reliability under varied operating conditions.
