The Bosch Rexroth SUPER LINEAR BUSH (R067222040) is a high-quality linear bushing designed for smooth travel and a long service life. This model, part of the Super LB B series, is characterized by its closed design with no self-alignment feature, which allows for the transfer of lower tipping forces along the axial direction. The KBB-20-DD model has a shaft diameter of 'd' and comes equipped with two seals to protect against contaminants. Crafted with steel bearing plates that have been meticulously machined to include ball guide grooves and optimized ball lead-in chamfers, this linear bushing ensures exceptionally smooth movement. It boasts a high travel speed capability (vmax) and can handle maximum accelerations (amax) efficiently. The balls within are made from rolling bearing steel, while the ball retainer and outer sleeve are constructed from either PA or POM materials. This Bosch Rexroth linear bushing does not require initial lubrication, making it ready for use upon installation. It features integrated wiper seals that contribute to its low friction force during operation when not under radial load. However, it's important to note that frictional drags can vary depending on speed and lubrication conditions. The dynamic load capacity of this product is significant, ensuring reliable performance over a total travel distance ranging from 10^5 m to 10^7 m without failure. Its permissible ambient temperature ranges from -20°C to +80°C, making it suitable for various operating environments. With a weight of 0.2 kg and specific radial clearance specifications for the shaft bore (hbore K), this linear bushing is engineered for precision applications where robustness and reliability are paramount.
