The Bosch Rexroth B.RUNNER BLOCK NR KWD-025-SLS-C0-H-1 (R201229330) is a high-precision, corrosion-resistant ball runner block designed for linear motion applications requiring a slimline width, long length, and standard height configuration. This runner block is crafted from Resist NR steel in accordance with DIN EN standards, ensuring its durability and resistance to corrosive environments. It boasts a preload class C, indicating that it is preload-free, and an accuracy class H for high precision. Featuring an overall length of 63 mm and capable of operating within a permissible ambient temperature range of -10°C to +100°C for short periods, this ball runner block is well-suited for applications with restricted space in the transverse direction. The dynamic load capacity C and dynamic torsional moment load capacity Mt are determined based on 100 km travel as per DIN ISO standards. This product also offers excellent dynamic characteristics, with the ability to handle high torque loads and maintain the same high load ratings in all four main directions of loading. The B.RUNNER BLOCK NR KWD-025-SLS-C0-H-1 comes prelubricated from the factory with roller bearing grease Dynalub 510 for long-term lubrication over several years. It lacks a ball chain but features a patented entry zone that increases travel accuracy by up to six times. Attachments can be mounted from above due to its design, offering flexibility in assembly. This model is compatible with all SNS/SNO ball guide rails and offers interchangeability between the runner block and guide rails across every accuracy level. Its self-aligning capability allows for compensation of misalignments without self-alignment. The model does not include attachment elements on either front reference edge or a straight lube connection but provides exceptional performance even under external loads due to significantly reduced frictional oscillations and low friction force levels.
