The Bosch Rexroth B.RUNN. BLOCK NRII KWD-025-SNS-C1-N-0 (R201121404) is a high-precision ball runner block designed for linear motion applications requiring corrosion resistance and precision. This model is part of the Resist NRII series, made with corrosion-resistant steel conforming to DIN EN standards, ensuring durability and reliability in harsh environments. The B.RUNN. BLOCK NRII features a slimline width (SNS format), standard height, and an overall length of 84 mm. It is characterized by low preload (preload class C) and standard accuracy class N. The runner block body is engineered to provide excellent dynamic characteristics with its optimized entry-zone geometry and a high number of balls, which minimize variation in elastic deflection under load. The dynamic load capacity C is determined based on a 100,000 m travel as per DIN ISO standards, while the static longitudinal moment load capacity ML and dynamic torsional moment load capacity Mt offer robust performance metrics for various applications. This model does not include a ball chain or initial lubrication, allowing for customization according to specific application requirements. The product also boasts an integrated all-around sealing system that protects against contaminants, thus extending the service life of the runner block. Designed for long-term lubrication over several years, this ball runner block can accommodate attachments from above and features lube fittings with metal threads on all sides for ease of maintenance. It can withstand ambient temperatures ranging from -10°C to +100°C (admissible for short time) and offers low frictional oscillations with a friction coefficient between 0.01 to 0.02. With its ability to handle high load ratings in all four main loading directions and compatibility with all SNS ball guide rails available in five common sizes, the Bosch Rexroth B.RUNN. BLOCK NRII KWD-025-SNS-C1-N-0 is suitable for applications where space is limited in the transverse direction and where clean room conditions or exposure to water-based media are prevalent.
