The Bosch Rexroth B.RUNNER BLOCK CS KWC-020-FNN-C0-N-2 (R169389410) is a high-precision ball runner block designed for linear motion applications requiring compactness and accuracy. The runner block body, crafted from unalloyed steel CS, ensures durability and robustness. It is part of the FNN series, characterized by a flange width, normal length, and low height profile. The B.RUNNER BLOCK CS comes with a standard accuracy class N and is preload-free (preload class C), making it suitable for applications where no preloading is required. This model does not include a ball chain and arrives preserved but without initial lubrication. It features angular lube nipples that are loosely attached for easy maintenance and long-term lubrication capabilities potentially spanning several years. The runner block body's standard version has an overall length that allows for interchangeability with guide rails of every accuracy level. The B.RUNNER BLOCK CS KWC-020-FNN-C0-N-2 is engineered to deliver maximum precision with its patented entry zone, which can increase travel accuracy by up to six times while significantly reducing frictional oscillations. The design also offers low friction levels, particularly under external loads. Its integrated all-around sealing provides protection against contaminants, contributing to its high torque load capacity. Additionally, the unit supports end-face fastening threads for various attachments and can be used on all SN/SNO ball guide rails. Its optimized entry zone geometry combined with a high number of balls reduces the variation in elastic deflection, enhancing performance reliability. With its self-aligning capability to compensate for misalignments and without the need for a ball chain as standard, this runner block maintains a low friction coefficient between 0.01 and 0.02. It can withstand dynamic load capacities as specified by DIN ISO norms and allows attachments from both above and below the runner block body. In summary, the Bosch Rexroth B.RUNNER BLOCK CS KWC-020-FNN-C0-N-2 is an adaptable component suited for various applications where space is restricted upwards but precision movement is essential.
