The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-FNS-C3-U-1 (R165123922) is a high-precision ball runner block designed for linear motion applications requiring ultra precision and high rigidity. This runner block is part of the CS series and features a size 25 profile with a flange width, normal length, and standard height. It is crafted from unalloyed steel CS, ensuring durability and strength for demanding tasks. The runner block boasts a high preload class C, indicating that it provides a higher degree of rigidity and can support higher loads with reduced deflection. The accuracy class UP (Ultra Precision) of this model ensures maximum travel accuracy, which is further enhanced by the patented entry zone that can increase travel accuracy by up to six times. The ball chain design contributes to low noise levels and optimal travel behavior. Additionally, the ball runner block comes prelubricated with Roller bearing grease Dynalub for maintenance-free operation over extended periods. This model does not include attachment elements on either front reference edge but offers straight lube connection loosely attached for easy maintenance. It also features all-around sealing to protect against contaminants and metal thread lube fittings accessible from all sides. The B.RUNNER BLOCK CS KWD-025-FNS-C3-U-1 can be used with all SN/SNO ball guide rails, providing flexibility in application. With its ability to withstand high torque loads and accommodate different preload classes, this Bosch Rexroth runner block is suitable for applications where precise movement and load support are critical. Its optimized geometry minimizes variations in elastic deflection, enhancing system rigidity even under liftoff or side loading conditions. The dynamic load capacity C and static torsional moment load capacity Mt ensure reliable performance across various operational conditions within the permissible ambient temperature range of -10°C to +100°C (short-term operation).
