The Bosch Rexroth B.RUNNER BLOCK HS KWD-015-FNS-C2-P-1 (R200112290) is a high-speed ball runner block designed for precision and durability in linear motion applications. This runner block features a size FNS format, which indicates a flange width, standard height, and normal length. The body of the runner block is constructed from carbon steel CS, ensuring robustness and longevity. It has been classified under preload class C, which signifies a medium preload to balance rigidity with smooth motion. With an accuracy class P, this model guarantees precision in operation. Notably, it does not include a ball chain but comes with initial lubrication and preservation to facilitate immediate use upon installation. The roller bearing grease used is Dynalub, known for its quality in maintaining smooth movement over time. The Bosch Rexroth B.RUNNER BLOCK HS is designed without attachment elements at the left front reference edge and right front reference edge but includes a straight lube connection that is loosely attached for easy maintenance. The overall length of the runner block facilitates compatibility with various guide rails as they can be combined with each other across every accuracy level. This model excels in areas requiring maximum speeds and offers improved rigidity under liftoff and side loading conditions due to two additional mounting screw holes centrally located on the ball runner block. Its O-arrangement preloading contributes to maximum system rigidity while also featuring electrically insulating properties due to the inclusion of ceramic balls. Other notable capabilities include high torque load capacity, smooth and quiet operation due to an optimally designed ball return system, endface fastening threads for versatile attachment options, patented entry zones that significantly increase travel accuracy, long-term lubrication potential spanning several years without needing replenishment, and high load ratings consistent in all four main loading directions. The product is available in eight common sizes to suit various application requirements.
