The Bosch Rexroth B.RUNNER BLOCK NR KWD-035-SLS-C1-H-1 (R201231330) is a high-precision, corrosion-resistant ball runner block designed for linear motion applications where space is limited in the transverse direction. This model features a slimline (SLS) format with a long length and standard height, ensuring compatibility with restricted spaces without compromising on functionality. The runner block body is constructed from corrosion-resistant steel compliant with DIN EN standards, making it suitable for environments where corrosion protection is essential. The B.RUNNER BLOCK NR KWD-035-SLS-C1-H-1 offers low preload (Preload class C) and high accuracy (Accuracy class H), which contribute to its smooth operation and precise movement control. It lacks a ball chain, opting instead for initial factory lubrication and preservation that facilitate long-term lubrication over several years. The roller bearing grease Dynalub 510 enhances the block's performance under various conditions. This ball runner block model boasts excellent dynamic characteristics, including reduced frictional oscillations and low friction force levels, especially under external loads. Its patented entry zone increases travel accuracy by up to six times. Attachments can be mounted from above for added convenience during installation or maintenance. With an overall length of 123 mm and a height of 48 mm when paired with a guide rail, the B.RUNNER BLOCK NR KWD-035-SLS-C1-H-1 supports high torque load capacities and maintains the same high load ratings in all four main loading directions. It has been tested for dynamic load capacity based on 100 km travel as per DIN ISO standards, confirming its robustness for demanding applications. This Bosch Rexroth ball runner block is versatile enough to be used on all SN/SNO ball guide rails and can withstand ambient temperatures ranging from -10°C to +100°C for short periods. Its design allows self-alignment to compensate for any misalignments during operation, ensuring consistent performance even in challenging installations.
