The Bosch Rexroth B.RUNNER BLOCK CR KWC-065-FNS-C0-H-2 (R165169360) is a high-precision ball runner block designed for linear motion applications where rigidity and load capacity are critical. This component is part of the Ball Rail Systems product group and is specifically crafted to provide maximum rigidity in all load directions, which makes it suitable for heavy-duty machine construction. The ball runner block boasts an improved rigidity under liftoff and side loading conditions, thanks to two additional mounting screw holes at its center. Constructed with a steel body that has a Resist CR coating, the runner block is hard chrome plated with a matte silver finish, offering corrosion resistance and durability. It comes prelubricated from the factory, allowing for long-term lubrication over several years without the need for immediate maintenance. The optimized entry-zone geometry and a high number of balls ensure minimal variation in elastic deflection, contributing to its quiet and smooth operation. This particular model has a size E profile with a flanged format (FNS), normal length, and standard height. It does not include a ball chain or attachment elements on either reference edge but comes with angular lube nipples loosely attached for ease of maintenance. The dynamic load capacity C and static torsional moment load capacity Mt are determined based on DIN ISO standards ensuring reliability in performance. The Bosch Rexroth B.RUNNER BLOCK CR KWC-065-FNS-C0-H-2 (R165169360) also features self-aligning capabilities to compensate for misalignments during installation or operation. Its seals are designed to prevent ingress of contaminants such as dirt or cutting fluids, thereby extending the service life of the component. With its high accuracy class H and preload class C indicating preload-free condition, this model is tailored for applications demanding high precision without clearance in movement.
