The Bosch Rexroth B.RUNNER BLOCK CS KWD-025-CNS-C1-H-1 (R16722132Z) is a high-precision ball runner block designed for linear motion applications requiring compact size, high accuracy, and low preload. This runner block is part of the Ball Rail Systems product group and is characterized by its compact width (CNS format), standard height, and normal length. It features a steel CS body with a high accuracy class H and low preload class C, ensuring smooth and precise movements. The B.RUNNER BLOCK CS KWD-025-CNS-C1-H-1 does not include a ball chain but comes with initial lubrication and preservation, using Roller bearing grease Dynalub for long-term performance. The runner block has an overall length specified in the product details and supports high torsional moments on guide rails where lateral space is limited. It offers excellent dynamic characteristics, including a very high torsional moment load capacity and resistance to torsion. Designed to accommodate high load ratings in all four main loading directions, this runner block ensures long-term lubrication over several years without the need for frequent maintenance. It includes integrated all-around sealing for protection against contaminants and two additional mounting screw holes at the center to improve rigidity under lift-off and side loading conditions. This model can be used with all BNS ball guide rails, providing flexibility in application use. It also boasts a wide range of accessories, end-face fastening threads for attachments, optimized entry-zone geometry, a high number of balls for reduced elastic deflection variation, and maximum system rigidity due to its pre-tensioned O-arrangement. The product's design allows for easy attachment from above and is self-aligning to compensate for misalignments without the need for self-alignment features. The friction coefficient is minimized due to the four-row ball design with point contact in all loading directions. This model is also equipped with double-lip seals (DS) as standard for increased exposure protection against media. In summary, the Bosch Rexroth B.RUNNER BLOCK CS KWD-025-CNS-C1-H-1 (R16722132Z) offers superior performance in precision linear motion applications where space is at a premium yet demands for accuracy are uncompromised.
