The Bosch Rexroth B.RUNN. BLOCK NRII KWD-020-SKS-C0-H-0 (R201089304) is a ball runner block designed for precision linear movement in various applications. This product features a slimline width, short length, and standard height, making it suitable for restricted spaces in both longitudinal and transverse directions. The runner block body is made from corrosion-resistant steel according to DIN EN standards, ensuring durability and resistance to harsh environments. With an accuracy class of H for high precision and a preload class C indicating it is preload-free, this model ensures smooth motion without unnecessary tension on the system. It lacks a ball chain and comes without initial lubrication or preservation, allowing for customization based on specific application requirements. The runner block has an overall length of 20 mm and can be used with all SNS ball guide rails, providing interchangeability and flexibility in design. Its optimized entry-zone geometry coupled with a high number of balls reduces variation in elastic deflection, which enhances travel accuracy significantly. For lubrication needs, this model includes a minimum quantity lubrication system with an integrated reservoir for oil lubrication, extending the maintenance intervals. Attachments can be easily mounted from above the runner block due to its design. It is capable of handling high load ratings in all four main loading directions while maintaining maximum precision. In terms of environmental adaptability, it can operate within ambient temperatures ranging from -10°C to +100°C but requires consultation for use at negative temperatures. The dynamic load capacity C and dynamic torsional moment load capacity Mt are determined based on a nominal 100 km travel as per DIN ISO standards. This Bosch Rexroth ball runner block is particularly suited for long-term use where reduced frictional oscillations and low friction force levels are critical under external load conditions. It offers excellent dynamic characteristics suitable for various applications requiring precise linear motion control.
