The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FNS-C3-U-1 (R16512392Z) is a ball runner block designed for ultra precision linear motion applications. This high-performance component features a size 25 flange width, normal length, and standard height, constructed from robust unalloyed steel CS. The runner block is distinguished by its high preload (class C) and ultra precision accuracy (class UP), ensuring maximum precision and rigidity for demanding tasks. It does not include a ball chain but comes with initial lubrication and preservation for immediate use. This runner block is equipped with roller bearing grease Dynalub, enhancing its durability and performance. It boasts an overall length of . mm and offers interchangeability with guide rails of every accuracy, making it versatile for various configurations. The product is engineered to provide excellent dynamic characteristics, significantly reduced frictional oscillations, and a low friction force level, especially under external loads. Notable features include the patented entry zone that improves travel accuracy by up to six times, attachments that can be mounted from above or below, metal-threaded lube fittings on all sides, end-face fastening threads for all attachments, integrated all-around sealing, and high torque load capacity. The B.RUNNER BLOCK CS KWD-025-FNS-C3-U-1 offers different preload classes to suit specific application needs and ensures high rigidity in all load directions which allows for the use of just one runner block per rail. Additional enhancements to rigidity under lift-off and side-loading conditions are provided by two extra mounting screw holes at the center of the runner block. Maximum system rigidity is achieved through the preloaded O-arrangement. An optional integrated inductive measuring system adds to its functionality without causing wear. The runner block has been pre-lubricated at the factory for long-term maintenance-free operation and can be used on all SN/SNO ball guide rails. It maintains consistent high load ratings in all four primary loading directions due to its robust design. The permissible ambient temperature range extends from min ... max °C, accommodating various operating environments.
