The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FNS-C2-N-1 (R165122420) is a high-precision ball runner block designed for linear motion applications. It features a flanged width, normal length, and standard height, which is identified by its FNS format. The runner block body is constructed from unalloyed steel CS and designed to provide medium preload as indicated by its preload class C. With an accuracy class N for normal precision, this component ensures consistent performance. This runner block comes without a ball chain but includes initial lubrication and preservation for immediate use. It utilizes roller bearing grease Dynalub to maintain smooth operation. The absence of attachment elements on both the left and right front reference edges allows for versatile installation options. The overall length of the runner block is specified in the product details, and it can be interchangeably combined with guide rails of every accuracy level to meet various application requirements. This model has been tested to perform reliably within an ambient temperature range as noted in the specifications, with allowances made for short-term exposure outside this range upon consultation. Dynamic load capacities and load moments are based on a 100,000 m travel per DIN ISO standards, ensuring durability and longevity under movement. The product also boasts a maximum permissible linear speed (vmax) and can accommodate misalignments without self-alignment capability. The B.RUNNER BLOCK CS KWD-025-FNS-C2-N-1 is part of the size B profiled rail systems with an average preload (class C) and comes equipped with standard seals (SS). Its dynamic longitudinal moment load capacity ML and static torsional moment load capacity Mt are detailed in the product specifications. Designed specifically as part of Bosch Rexroth's ball rail system offerings, this runner block supports smooth linear guidance while handling significant loads efficiently. Its weight and nominal size are provided for accurate planning in system integration.
