The Bosch Rexroth MINI R.BLOCK NRII (R044451201) is a high-precision, miniature ball runner block designed for linear motion applications requiring compact and corrosion-resistant components. This model boasts an SLS format, which stands for slimline width, long length, and standard height, ensuring a sleek profile that can fit into tight spaces while providing reliable guidance. Constructed with corrosion-inert steel, the runner block body is durable and suitable for various environments. It features a low preload class C and precision accuracy class P, indicating that the component is preloaded to a lower degree for reduced rigidity and friction, while maintaining precise movement within the system. The absence of a ball chain simplifies the design and eases replacement processes. The MINI R.BLOCK NRII comes with initial lubrication but without preservation, utilizing Roller bearing grease Dynalub for smooth operation. It has an integrated lube nipple for easy maintenance and relubrication. The runner block's overall length measures at . mm, making it compact yet capable of handling dynamic loads efficiently. This model does not include attachment elements on either front reference edge but offers interchangeability with guide rails of different accuracy classes (P, H, and N). Its design facilitates smooth and quiet operation through an optimally designed ball return system. The permissible ambient temperature range extends from min ... to max ... °C for short durations without compromising performance. Dynamic load capacity C and static load ratings are calculated according to DIN standards, ensuring reliable operation under specified loads. With its self-aligning capability, the MINI R.BLOCK NRII can compensate for misalignments in the application without requiring additional self-alignment features. Designed primarily as part of size A profiled rail systems but compatible with various sizes (N, E, K), this miniature ball runner block is suited for high-speed applications up to a maximum permissible linear speed vmax. Its robust construction allows it to withstand both static and dynamic torsional moment loads effectively. In summary, the Bosch Rexroth MINI R.BLOCK NRII (R044451201) is a versatile and precise miniature ball runner block ideal for applications demanding compactness, precision movement, corrosion resistance, and durability in challenging environments.
