The Bosch Rexroth B.RUNNER BLOCK SS KWD-020-SKS-C1-H-1 (R166281320) is a high-precision ball runner block designed for linear motion applications requiring self-alignment capabilities and smooth operation. This model is part of the SKS series, which features a slimline width, short length, and standard height, making it suitable for compact installations where space-saving is crucial. The runner block body is constructed from carbon steel CS, ensuring durability and robustness in various operational conditions. With a preload class C indicating low preload and an accuracy class H for high accuracy, this runner block is engineered to deliver precise movement with minimal friction. It does not include a ball chain but comes with initial lubrication and preservation to reduce maintenance needs. The roller bearing grease used is Dynalub 510. This product's self-adjusting feature allows it to compensate for alignment errors up to specified degrees across multiple levels, ensuring consistent performance even when there are deviations in mounting bases. It boasts high load ratings in all four main loading directions due to its design that includes lube fittings with metal threads on all sides. Its optimal return design ensures smooth ball pickup and entry during operation. The B.RUNNER BLOCK SS KWD-020-SKS-C1-H-1 can be used interchangeably with all SNS ball guide rails within the same accuracy class due to its universal compatibility. This interchangeability extends the potential applications of this runner block across various industries requiring linear motion solutions. Furthermore, the Bosch Rexroth ball rail system emphasizes reduced friction through its four rows of balls point contact design. Standard seals (SS) are included to prevent contaminants from entering the system, maintaining its service life while also offering options for low-friction seals (LS), double-lip seals (DS), front seals, FKM seals, and cover plate wipers as additional accessories for different environmental requirements. In summary, the Bosch Rexroth B.RUNNER BLOCK SS KWD-020-SKS-C1-H-1 offers superior self-aligning capabilities with high accuracy and low preload for smooth operation in linear motion applications while providing versatility through its interchangeable components with other profiled rail systems within its class.
