The Bosch Rexroth MINI R.BLOCK NRII (R044229401) is a miniature ball runner block designed for precision and ease of use in various linear motion applications. This product belongs to the SNS format, which denotes a slimline width, normal length, and standard height. The runner block body is constructed from corrosion-resistant steel, ensuring durability and longevity in challenging environments. This model features a preload class C, indicating that it is preload-free, and an accuracy class N for standard accuracy requirements. It does not include a ball chain but comes with initial lubrication while lacking preservation measures. The roller bearing grease used is Dynalub 510, known for its high performance. The MINI R.BLOCK NRII has relubrication openings to facilitate maintenance and ensure smooth operation over time. Its overall length is specified to accommodate the corresponding guide rails effectively. Notably, this runner block boasts interchangeability with guide rails across various accuracy classes (P, H, and N), enhancing its versatility. This model has been engineered without attachment elements on both the left and right front reference edges. It also features ball retention capabilities that simplify the replacement process when necessary. The dynamic load capacity of this component adheres to DIN standards, ensuring reliable performance under specified conditions. The Bosch Rexroth MINI R.BLOCK NRII's profiled rail systems come in different sizes (A, B, E, H, S, T), each tailored to specific application needs. It accommodates a maximum permissible linear speed of up to 5 m/s; however, at such speeds, service life may be impacted due to increased wear on plastic parts. This miniature ball runner block operates within an ambient temperature range of -10°C to +100°C and can withstand short-term deviations from these limits as specified in the product footnotes. With its low-friction seal design and absence of self-alignment features, the MINI R.BLOCK NRII ensures smooth operation while maintaining static and dynamic load capacities as calculated per relevant standards.
