The Bosch Rexroth SUPER LINEAR BUSH (R067204000) is a high-quality linear motion component designed for applications requiring smooth and precise linear travel. This model features steel bearing plates with machined ball guide grooves and optimized ball lead-in chamfers, ensuring exceptionally smooth travel and a long service life. The SUPER LINEAR BUSH is a closed type without self-alignment feature, which allows it to transfer lower tipping forces along the axial direction. With a shaft diameter of 40 mm and an outer diameter of D, the KBB-40 model operates without seals, making it a low-cost solution for high-performance requirements. The absence of seals minimizes frictional drags, which depend on speed and lubrication conditions. It is capable of high travel speeds up to v_max (speeds up to m/s possible), although service life may be limited due to increased wear on plastic parts. The ball retainer and outer sleeve are constructed from either PA or POM, while the balls are made from rolling bearing steel. This configuration does not require initial lubrication. The product's maximum dynamic load capacity (C_max) and maximum acceleration (a_max) are designed to work within the given specifications when based on a total travel distance of 100,000 m. This linear bushing operates efficiently within a permissible ambient temperature range of -20°C to +80°C. Its design includes options for integrated wiper seals or external seals for added protection against contaminants. The friction coefficient ranges from 0.001 to 0.005 with a maximum of 0.025 under certain conditions. The Bosch Rexroth SUPER LINEAR BUSH KBB-40 is part of Productgroup ID 23, indicating its classification within the manufacturer's product lineup. It offers minimal static load capacity (C_min) and maximum static load capacity (C_max), with dynamic load capacities based on extensive travel testing. Overall, this model provides reliable performance in linear motion applications where precision movement is essential without the need for initial lubrication or self-alignment features.
