The Bosch Rexroth B.RUNN. BLOCK NRII KWD-015-SNS-C0-N-0 (R201119406) is a high-precision, corrosion-resistant ball runner block designed for linear motion applications requiring slimline width and standard height configurations. This model, part of the SNS size series, is characterized by its Resist NRII material which provides exceptional durability in challenging environments. The runner block body and all steel components are manufactured from corrosion-resistant steel in accordance with DIN standards. The B.RUNN. BLOCK NRII comes preload-free (preload class C) and boasts a standard accuracy class (N), ensuring reliable performance without the need for initial adjustment. It features a ball chain that promotes smooth travel behavior and reduces noise levels during operation. The lack of preservation and initial lubrication allows users to apply their preferred lubrication method, tailored to specific application requirements. With an overall length of 92 mm, this runner block supports interchangeable use with guide rails across various accuracy levels, enhancing its versatility. Its design accommodates restricted spaces in the transverse direction and enables long-term lubrication over extended periods. The patented entry zone significantly improves travel accuracy—by up to six times—especially under external loads. The Bosch Rexroth B.RUNN. BLOCK NRII is equipped with lube fittings that have metal threads on all sides for easy maintenance and offers attachments that can be mounted from above the block. It delivers consistent high load ratings in all four main loading directions and includes an integrated reservoir for oil lubrication to promote optimal performance over time. This product also features an integrated all-around sealing system to protect against contaminants, while its optimized entry zone geometry coupled with a high number of balls minimizes variation in elastic deflection, providing excellent dynamic characteristics suitable for various industrial applications where precision and durability are paramount.
