The Bosch Rexroth B.RUNN. BLOCK NRII KWD-035-SNS-C0-N-0 (R201139404) is a high-quality ball runner block designed for precision linear movement in various applications. This model is crafted from Resist NRII, a corrosion-resistant material that ensures durability and consistent performance under challenging conditions. The runner block features a slimline width, standard height, and normal length (SNS format), with an overall length of 70.2 mm. It is engineered to offer standard accuracy class N and is preload-free with preload class C, meaning there are no pre-tensioning forces on the ball bearings, allowing for smooth movement. This ball runner block does not include a ball chain or any initial lubrication or preservation, giving users the flexibility to apply their preferred lubricants according to their specific application needs. The product also lacks attachment elements on both left and right front reference edges, offering a straightforward design that can be easily integrated into various systems. One of the standout features of this Bosch Rexroth ball runner block is its optimized entry-zone geometry combined with a high number of balls, which significantly reduces variation in elastic deflection and enhances travel accuracy – up to six times better compared to conventional designs. The dynamic characteristics are excellent due to these design optimizations. For maintenance purposes, the runner block boasts an integrated all-around sealing system that protects against contaminants such as dirt and coolants, thus extending the service life of the component. It has been designed for interchangeability with all SNS guide rails across every accuracy level. Additionally, it supports long-term lubrication for several years without the need for frequent maintenance. The B.RUNN. BLOCK NRII KWD-035-SNS-C0-N-0 is suitable for use where space is restricted in the transverse direction and can withstand ambient temperatures ranging from -10°C up to 100°C for short periods. With its robust construction and versatile design, this product delivers reliable performance in diverse industrial applications while maintaining low friction levels even under external loads.
