The Bosch Rexroth R.RUNNER BLOCK CS RWA-125-FNS-C2-H-2 (R186132310) is a high-precision roller runner block designed for linear motion applications requiring extreme load capacity and rigidity. This runner block features a size 125, FNS format which denotes a flanged width, normal length, and standard height. It is constructed from unalloyed steel CS, ensuring durability and strength. The preload class C indicates a medium preload while the accuracy class H signifies high precision. The RWA-125-FNS-C2-H-2 does not come with a roller chain and requires no initial lubrication. It is preserved for longevity and does not include attachment elements on either the left or right front reference edges. The lube connection is straight and loosely attached. With an overall length specified by the manufacturer, this runner block offers interchangeability with guide rails of varying accuracies. This heavy-duty roller runner block excels in heavy machine construction environments due to its exceptional load capacity. It provides maximum rigidity in all load directions and features additional mounting screw holes at the center for improved stability under liftoff and side loading conditions. High torque load capacity is another key feature of this model. The uniform Roller Guide Rails across all variants ensure limitless interchangeability and numerous combination options. Attachments can be mounted both above and below the runner block, enhancing versatility. Innovative channel design allows for minimal lubrication quantities while ensuring smooth operation. The optimized design of return pathways and guideways delivers quiet running with minimal elastic deflection variation due to its optimized entry zone geometry and the high number of rollers employed. Aluminum end caps are available for sizes 25+ or plastic for smaller sizes, while integrated front seals come standard to improve sealing across all running tracks. This product's capabilities are further underscored by its compatibility with various profiled rail systems (sizes A, B, E, H, K, N, S, T), each offering specific advantages in terms of static or dynamic load capacities, torsional moment capacities, friction coefficients, permissible ambient temperatures, acceleration limits, preload forces, linear speeds, sealing options (like Doublelip seal DS), material compositions (carbon steel), tolerance profiles as well as weight considerations for comprehensive application suitability according to DIN ISO standards.
