The Bosch Rexroth B.RUNNER BLOCK CS KWD-030-FLS-C0-N-1 (R165379420) is a high-precision ball runner block designed for linear motion applications requiring optimal rigidity and dynamic characteristics. This model features a steel CS runner block body, standard width flange, long length, and standard height, ensuring durability and compatibility with various setups. It is characterized by a preload class C, indicating it is preload-free, and an accuracy class N for standard precision. The R165379420 does not include a ball chain but comes with initial lubrication and preservation for reduced maintenance efforts. The straight lube connection is loosely attached for easy access. Designed without attachment elements on the front reference edges, this model promotes ease of installation and flexibility in design. Its overall length and height are tailored to meet the demands of size E profiled rail systems. Notably, the B.RUNNER BLOCK CS KWD-030-FLS-C0-N-1 boasts interchangeability features allowing it to be combined with guide rails of every accuracy level. The patented entry zone significantly enhances travel accuracy by up to six times. It supports long-term lubrication over several years thanks to its lube fittings with metal threads on all sides. This model ensures high torque load capacity across various preload classes and exhibits high rigidity in all load directions, which enables use with a single runner block per rail in certain applications. The additional mounting screw holes at the center increase rigidity under liftoff and side-loading conditions. For those seeking an integrated measuring system, an optional inductive and wear-free option is available. The R165379420 can be mounted from both above and below on attachments and is compatible with all SN/SNO ball guide rails while maintaining high load ratings in all four main loading directions. Pre-lubricated at the factory, this ball runner block stands out for its excellent dynamic load capacity, static torsional moment load capacity, maximum permissible linear speed vmax, low friction coefficient, and robust sealing options including standard SS seals suitable for most environments; LS low-friction seal; DS double-lip seal; front seal; FKM seal; cover plate wiper—all interchangeable during servicing—to protect against contaminants that could affect performance or longevity.
