The Bosch Rexroth SUPER LINEAR BUSH KBB-50-D (R067215040) is a high-performance linear bushing designed for smooth, precise linear movement in various applications. This model is part of the Super LB B series, which is characterized by its closed design and lack of self-alignment feature, making it ideal for transferring lower tipping forces along the axial direction. It has a shaft diameter of 'd' and comes with one seal to protect against contaminants. Constructed with steel bearing plates that have machined ball guide grooves and optimized ball lead-in chamfers, the KBB-50-D ensures outstandingly smooth travel and a long service life. The bushing achieves high travel speeds up to 'vmax' meters per second, although it should be noted that service life may be limited due to increased wear on plastic parts at such speeds. Tests have indicated total travel ranging from 10^4 m to 10^5 m without failure. The KBB-50-D features a ball retainer and an outer sleeve made from either PA or POM materials, while the balls themselves are crafted from rolling bearing steel. This model does not require initial lubrication, which simplifies installation and maintenance. The dynamic load capacities are significant; with minimum dynamic load capacity 'Cmin' and maximum dynamic load capacity 'Cmax', these values are based on a total travel distance of 100 km. Additionally, the product can operate within a wide range of ambient temperatures from minimum 'Tmin' degrees Celsius to maximum 'Tmax' degrees Celsius. The friction coefficient varies between minimum 'fmin' to maximum 'fmax', indicating efficiency under different load conditions. This linear bushing weighs in at . kg and has radial clearance specifications for different fits (shaft bore K, H, M). Overall, the Bosch Rexroth SUPER LINEAR BUSH KBB-50-D offers reliable performance for applications requiring precise linear motion without self-alignment capabilities.
