The Bosch Rexroth MINI R.BLOCK NRII (R044259401) is a high-quality miniature ball runner block designed for precision linear motion applications. This model, belonging to the Miniature ball rail system product group, is engineered with a focus on reliability and performance. The runner block body is constructed from corrosion-resistant steel, ensuring durability and long service life even in challenging environments. The MINI R.BLOCK NRII features a slimline width (SNS format), standard length, and height, making it suitable for applications where space is at a premium. The preload class C indicates that the runner block is preload-free, while the accuracy class N denotes standard precision levels. This model does not include a ball chain but comes with initial lubrication and without preservation for immediate use. With an integrated lube nipple and a roller bearing grease called Dynalub, this runner block maintains smooth and quiet operation. It boasts an overall length of 15 mm and is designed without attachment elements on both left and right front reference edges. Notably, it offers interchangeability with guide rails across all accuracy classes P, H, and N. The MINI R.BLOCK NRII has a dynamic load capacity calculated according to DIN standards, ensuring robust performance under various load conditions. It supports maximum accelerations while maintaining low-friction movement due to its optimally designed ball return system. For maintenance convenience, it features a relubrication hole. This runner block can operate within an ambient temperature range of -10°C to +100°C for short periods without compromising its function or integrity. Furthermore, the static torsional moment load capacity Mt is calculated based on dynamic load capacity values derived from C0. In summary, the Bosch Rexroth MINI R.BLOCK NRII (R044259401) offers precise linear guidance in compact spaces with easy maintenance and interchangeability options suitable for diverse applications requiring miniature profiled rail systems.
