The Bosch Rexroth B.RUNNER BLOCK AL (R163289420) is a high-precision aluminum ball runner block designed for various industrial applications that require compact, lightweight, and robust linear motion solutions. This runner block is part of Bosch Rexroth's Ball Rail Systems and is notable for its slimline width, normal length, and standard height format within the SNS size range. The body of the runner block is constructed from aluminum, offering a significant weight reduction compared to steel versions without compromising on precision or load capacity. With an accuracy class N (normal) and preload class C (preload-free), this model ensures smooth motion without pre-tensioning, which is ideal for applications that necessitate minimal friction and wear. It features an optimized entry zone geometry and a high number of balls to reduce variation in elastic deflection, enhancing travel accuracy. The B.RUNNER BLOCK AL does not include a ball chain but comes with initial lubrication and preservation for reduced maintenance requirements. This particular model has been engineered for dynamic performance with excellent dynamic characteristics suitable for high-speed applications. It allows for maximum permissible torsional moments and longitudinal load moments specific to its size category. Furthermore, the unit has predrilled holes for pinned fitting, facilitating precise mounting and alignment while enabling greater parallelism and height offsets of mounting bases. The Bosch Rexroth B.RUNNER BLOCK AL is designed with interchangeable compatibility in mind; it can be used with all SNS ball guide rails within each accuracy class. This feature provides flexibility in system design and simplifies inventory management. Long-term lubrication capabilities extend the maintenance intervals significantly, contributing to reduced downtime. In terms of sealing options, this model accommodates various seal types including standard seals (SS) for general protection against contaminants like dirt and chips as well as specialized seals like low-friction seals (LS), double-lip seals (DS), front seals, FKM seals, and cover plate wipers that cater to more demanding environmental conditions or specific application requirements. Overall, the Bosch Rexroth B.RUNNER BLOCK AL offers an ideal solution for those seeking a reliable linear guide system with excellent load capacity, precision movement capabilities, low weight advantages of aluminum construction, and versatile sealing options suitable across different industry applications.
