The Bosch Rexroth SUPER LINEAR BUSH KBB-25-D (R067212540) is a high-quality linear bushing designed for smooth and precise linear motion. This closed-type linear bushing is engineered without a self-alignment feature, which makes it suitable for applications where lower tipping forces are transferred along the axial direction. With a shaft diameter of 'd,' the KBB-25-D model ensures a tight fit and reliable operation. Crafted with steel bearing plates that have machined ball guide grooves and optimized ball lead-in chamfers, this linear bushing provides exceptionally smooth travel and a long service life. The product is capable of handling high travel speeds up to 'vmax' meters per second, although service life may be limited by increased wear to plastic parts under such conditions. It has been tested to achieve total travel from 10^4 m to 10^5 m without failure. The KBB-25-D comes equipped with one seal, which results in reduced friction force 'FR.' For applications requiring additional sealing, there's an option to multiply the value by a factor of 1.2. The balls are crafted from rolling bearing steel, ensuring durability and consistent performance. No initial lubrication is required for this model, simplifying maintenance routines. This linear bushing operates effectively within a permissible ambient temperature range of '-20°C ... +80°C'. Its design includes ball retainers and an outer sleeve made from PA or POM materials, contributing to its low friction coefficient ranging from '0.01 ... 0.025' to a maximum of '0.3'. The dynamic load capacities are based on total travel of 100 km but can be adjusted based on different travel distances. Finally, the Bosch Rexroth SUPER LINEAR BUSH KBB-25-D weighs just '0.23 kg' and offers various radial clearance options for shafts with bore tolerances classified as K, H, or M standards. This product belongs to the Productgroup ID 'Linear bushing and shaft' category and is characterized by its closed format for enhanced rigidity and performance in linear motion systems.
