The Bosch Rexroth B.RUNNER BLOCK AL (R163121420) is a high-precision aluminum ball runner block designed for use in linear motion applications where reduced weight and high accuracy are required. This runner block is part of the Ball Rail Systems and features an FNS format, indicating a flange width, normal length, and standard height. It has been engineered with a body made of aluminum to ensure a lightweight yet durable design. The B.RUNNER BLOCK AL comes with a low preload (preload class C) and standard accuracy (accuracy class N), without a ball chain, offering straightforward installation and maintenance. It has been pre-lubricated with Roller bearing grease Dynalub to facilitate immediate operation and long-term lubrication potential over several years. This model boasts an optimized entry zone geometry and an increased number of balls to reduce variation in elastic deflection, enhancing travel accuracy significantly—up to six times according to patented technology. The runner block's compatibility with all SNS ball guide rails allows for limitless interchangeability within each accuracy class, ensuring flexibility across various applications. Key features include improved rigidity under liftoff and side loading conditions due to additional mounting screw holes at the center, as well as predrilled holes for pinned fitting which aid in achieving greater parallelism and height offsets of mounting bases. The unit's smooth operation is attributed to its well-designed ball return system and guideway. The B.RUNNER BLOCK AL can handle maximum permissible torsional moments (Mt max) effectively while operating within a permissible ambient temperature range specified in the detailed product specifications. Its dynamic load capacity (C) is determined based on travel per DIN ISO standards, ensuring reliable performance under dynamic conditions. In summary, the Bosch Rexroth B.RUNNER BLOCK AL is tailored for lightweight design applications requiring maximum precision, interchangeability across rail systems, and efficient long-term lubrication management—all contributing to its suitability for various industrial robot and general machine building tasks.
