The Bosch Rexroth B.RUNNER BLOCK NR KWD-025-FNS-C0-H-1 (R200129332) is a high-precision, corrosion-resistant ball runner block designed for linear motion applications. This runner block is part of the Ball Rail Systems product group and is notable for its Resist NR material, which offers robustness against corrosive elements. It comes in size 25 with FNS format, indicating a flange width, normal length, and standard height. The runner block body adheres to DIN EN standards for corrosion resistance. This model features a high accuracy class H and is preload-free (preload class C0), ensuring smooth motion without initial tension. It includes a ball chain that contributes to reduced noise levels and optimal travel behavior. The overall length of the runner block is specified at 63 mm. The B.RUNNER BLOCK NR KWD-025-FNS-C0-H-1 boasts excellent dynamic characteristics suitable for various applications requiring significant rigidity, low frictional oscillations, and precision under external load conditions. Its design allows for long-term lubrication over several years without frequent maintenance, facilitated by the initial factory lubrication using Roller bearing grease Dynalub 510. Additionally, this model supports high torque load capacity and improved rigidity due to additional mounting screw holes at the center of the block for liftoff and side loading conditions. The ball runner block maintains high load ratings in all four main directions of loading. It's also designed with interchangeability in mind; it can be combined with any guide rails within the same accuracy range without compatibility issues. Attachments can be mounted from both above and below the runner block, providing flexibility in assembly. In terms of environmental adaptability, this ball runner block can operate within an ambient temperature range from -10°C to +100°C but consult Bosch Rexroth for use at negative temperatures. Lastly, this product comes equipped with standard seals (SS) that prevent contaminants from entering the internal mechanism while minimizing friction and maintaining an effective sealing performance.
