The Bosch Rexroth B.RUNNER BLOCK CS KWC-020-FNN-C1-H-2 (R169381310) is a high precision ball runner block designed for linear motion applications that require restricted upward space and maximum precision. This runner block is part of the Ball Rail System and features the FNN format, indicating a flange width, normal length, and low height. It is made from unalloyed steel CS and offers a low preload (Preload class C) with high accuracy (Accuracy class H). Notably, it comes without a ball chain. The B.RUNNER BLOCK CS KWC-020-FNN-C1-H-2 has been preserved but does not include initial lubrication or attachment elements on either the left or right front reference edges. It is equipped with angular lube nipples loosely attached for ease of maintenance. The body of the runner block adheres to standard specifications with an overall length specified by the product details. This model is characterized by its ability to combine interchangeably with guide rails across all accuracy levels, enhancing its versatility in use. Its patented entry zone contributes to a significant increase in travel accuracy—up to six times—while also reducing frictional oscillations and maintaining a low friction force level, especially under external loads. Long-term lubrication capabilities are possible over several years due to its design, which includes lube fittings with metal threads on all sides. The ball runner block also boasts an integrated all-around sealing system for protection against contaminants, ensuring durability and consistent performance. High torque load capacity and optional integrated measuring systems are available for precise motion control requirements. The optimized geometry of the entry zone alongside a substantial number of balls reduces variation in elastic deflection. The B.RUNNER BLOCK CS KWC-020-FNN-C1-H-2 can be utilized with all SN/SNO ball guide rails, providing flexibility in mounting attachments from both above and below the block. In terms of environmental adaptability, this model can operate within a wide temperature range while maintaining dynamic load capacity and moment load capacity as per DIN ISO standards. Its design ensures self-alignment to compensate for any misalignments during operation without requiring additional self-alignment mechanisms.
