The Bosch Rexroth B.RUNN. BLOCK NRII KWD-020-SLS-C1-H-0 (R201281306) is a ball runner block designed for precision and durability in linear motion applications. This component is part of the Ball Rail Systems product line, offering high accuracy with its H-class rating and low preload in class C. The B.RUNN. BLOCK NRII features a slimline width (SLS format), long length, and standard height, making it suitable for spaces with limited transverse room. Constructed from corrosion-resistant steel as per DIN EN standards, this runner block ensures longevity even in harsh environments. It includes a ball chain mechanism that contributes to its quiet operation and smooth travel behavior. The optimized entry zone geometry and the high number of balls reduce elastic deflection variation, enhancing travel accuracy by up to six times. This model does not come with initial lubrication or preservation but is designed for long-term lubrication that can last several years, thanks to its minimum quantity lubrication system with an oil reservoir. It offers versatility as it can be used with all SNS Ball Guide Rails and comes in five common sizes. The B.RUNN. BLOCK NRII boasts high load ratings in all four main loading directions, supporting dynamic load capacities effectively as per DIN ISO standards. Its design also allows for self-aligning to compensate for misalignments without the need for self-alignment features. In terms of technical specifications, the runner block body has an overall length of 70 mm and can handle maximum accelerations and speeds while maintaining a low friction coefficient between 0.01 to 0.02 without seal friction. It is equipped with standard SS seals to prevent contamination from dirt or coolants, ensuring reliable performance over time. Designed mainly for applications requiring precise linear motion under varying environmental conditions, the Bosch Rexroth B.RUNN. BLOCK NRII KWD-020-SLS-C1-H-0 is a testament to engineering excellence in linear guide technology.
