The Bosch Rexroth MINI R.BLOCK NRII MWA-012-SNS-C1-H-3 (R044221301) is a high-precision miniature ball runner block designed for linear motion applications requiring compact, highly accurate components. This product features a slimline width, normal length, and standard height (SNS format), with the runner block body constructed from corrosion-resistant steel. The low preload class C and high accuracy class H ensure smooth and precise movement. The MINI R.BLOCK NRII is devoid of a ball chain, but it includes initial lubrication without preservation, utilizing Roller bearing grease Dynalub for reduced maintenance. It does not come with attachment elements on either front reference edge but offers relubrication openings for easy maintenance. The overall length of the runner block is meticulously crafted to accommodate various applications. This model boasts interchangeability with guide rails across all accuracy classes (P, H, and N), providing flexibility in system design. Its dynamic load capacity and static load rating are calculated according to DIN standards, ensuring reliable performance under specified conditions. The runner block can handle a maximum permissible linear speed of up to 5 m/s, although this is limited by increased wear on plastic parts over time. Designed for self-aligning to compensate for misalignments without the need for self-alignment capability, the MINI R.BLOCK NRII also has impressive static and dynamic torsional moment load capacities. It operates within an ambient temperature range of -10°C to +100°C and can endure short-term exposure beyond these limits. This product belongs to the miniature ball rail system category within Bosch Rexroth's product offerings and stands out for its quiet operation due to an optimally designed ball return system. Its compact size does not compromise its ability to withstand significant loads while maintaining high precision in linear movements.
