The Bosch Rexroth B.RUNNER BLOCK NR KWD-030-FLS-C0-H-1 (R200279330) is a high-precision ball runner block designed for linear motion applications requiring corrosion resistance, high rigidity, and precision. This model is part of the FLS series, featuring a flanged, long, and standard height format with a runner block body made of corrosion-resistant steel compliant with DIN EN standards. It offers preload-free operation (preload class C) and falls under the high accuracy class H. The B.RUNNER BLOCK NR KWD-030-FLS-C0-H-1 is notable for its lack of a ball chain and comes with initial lubrication and preservation for long-term maintenance-free operation. The roller bearing grease used is Dynalub 520. The runner block has an overall length of 90 mm and can be combined with guide rails to meet the most demanding rigidity requirements while ensuring maximum precision. This product features an innovative patented entry zone that significantly enhances travel accuracy by up to six times compared to standard systems. It is capable of enduring high torque loads and maintains improved rigidity under lift-off and side loading conditions due to two additional mounting screw holes at its center. The runner block boasts excellent dynamic characteristics, making it suitable for all SN/SNO ball guide rails. Furthermore, the B.RUNNER BLOCK NR KWD-030-FLS-C0-H-1 supports limitless interchangeability within each accuracy class across all ball rail systems offered by Rexroth. This ensures flexibility in design and replacement options for various industrial applications. The unit's static load rating, dynamic load capacity, permissible ambient temperature range, friction coefficients, and dynamic torsional moment load capacity are all specified according to DIN ISO standards to ensure reliability and performance in diverse operating conditions.
