The Bosch Rexroth B.RUNNER BLOCK AL KWD-015-FNS-C0-H-1 (R163119320) is a high-precision aluminum ball runner block designed for linear motion applications where reduced weight and high accuracy are critical. This ball runner block belongs to the FNS format, signifying its flanged width, normal length, and standard height dimensions. Crafted from lightweight aluminum, it offers significant weight savings over traditional steel versions without sacrificing performance. The R163119320 model features a high accuracy class H and is preload-free (preload class C), ensuring smooth motion without any initial tension in the system. It does not include a ball chain but comes pre-lubricated with Roller bearing grease Dynalub for immediate use and long-term lubrication capabilities. The product is also equipped with straight lube connections that are loosely attached. This runner block boasts an optimized entry zone geometry coupled with a high number of balls to minimize variations in elastic deflection, contributing to its exceptional travel accuracy—up to six times improved compared to conventional designs. Its compact and lightweight design allows for lower gravity impact on systems, making it suitable for dynamic applications that benefit from reduced inertia. Moreover, the Bosch Rexroth R163119320 runner block features additional mounting screw holes at its center, enhancing rigidity under various loading conditions. It provides flexibility in assembly as attachments can be mounted from both above and below. The unit's design also facilitates limitless interchangeability within each accuracy class across all SNS ball guide rails. In summary, the Bosch Rexroth B.RUNNER BLOCK AL KWD-015-FNS-C0-H-1 (R163119320) offers maximum precision and interchangeability for diverse industrial applications while maintaining a lightweight profile suitable for innovative machine designs requiring exacting linear motion control.
