The Bosch Rexroth MINI R.BLOCK NRII MWA-015-BNS-C0-N-0 (R044359441) is a precision-engineered miniature ball runner block designed for use in profiled rail systems. This model, belonging to the BNS format, features a width that is wide, with standard height and normal length, ensuring compatibility with various applications requiring compact motion guidance systems. The runner block body is crafted from corrosion-resistant steel, providing durability and longevity even in challenging environments. With an accuracy class N indicating standard precision and a preload class C signifying it is preload-free, this runner block offers smooth and quiet operation without the need for initial preload adjustments. The absence of a ball chain simplifies the design while still allowing for easy ball replacement due to its ball retention capabilities. It also lacks initial lubrication and preservation, offering flexibility in maintenance according to application-specific requirements. This model does not include attachment elements at the left or right front reference edges but comes with an integrated lube nipple for simplified relubrication processes. Its overall length measures . mm, and it boasts interchangeability with guide rails across all accuracy classes (P, H, and N), enhancing its versatility. The runner block can withstand dynamic load capacities as calculated according to DIN standards and operates effectively within a permissible ambient temperature range of -20°C to +80°C. Furthermore, this MINI R.BLOCK NRII is self-aligning to compensate for potential misalignments during installation or operation. It features a low-friction seal designed specifically for miniature applications while maintaining impressive static and dynamic load capacities. Its compact size does not compromise on performance; it can achieve speeds up to 5 m/s though service life may be limited by increased wear on plastic components at such speeds. In summary, the Bosch Rexroth MINI R.BLOCK NRII MWA-015-BNS-C0-N-0 is suitable for users seeking high-quality motion guidance in compact spaces where corrosion resistance and interchangeability are necessary without the need for preloading or complex maintenance routines.
