The Bosch Rexroth SUPER LINEAR BUSH KBB-O-25-D (R067312540) is a meticulously designed linear bushing that stands out for its high-quality construction and performance capabilities. This open linear bushing, without self-alignment features, is ideally suited for applications on fully supported shafts where precision and resistance to warping are crucial. It has been engineered with steel bearing plates that have machined ball guide grooves and optimized ball lead-in chamfers, ensuring exceptionally smooth travel and an extended service life. The KBB-O-25-D is characterized by its low friction coefficient, which ranges from 0.01 to 0.025, indicating efficient operation even under varying load conditions. It boasts a dynamic load capacity (C) and static load rating (C0), signifying its ability to handle significant loads in the main direction of application. The product operates effectively within a permissible ambient temperature range of -30°C to +80°C, demonstrating versatility across different working environments. This model comes equipped with one seal that contributes to the unit's low frictional drags when not under radial load; these drags are influenced by speed and lubrication factors. The breakaway force is minimal, facilitating easy starts and stops during operation. Additionally, the bushing can achieve maximum permissible linear speeds of up to 5 m/s; however, it's important to note that at such high velocities, the service life may be limited due to increased wear on plastic components. With an outer diameter (D) of size E10 and a weight of 0.041 kg, this linear bushing maintains radial clearance within precise specifications for optimal performance. The design includes an integrated longitudinal seal or optional external seals for protection against contaminants. The ball retainer and outer sleeve are constructed from PA or POM materials while the balls themselves are made from rolling bearing steel—no initial lubrication is required upon installation. Overall, the Bosch Rexroth SUPER LINEAR BUSH KBB-O-25-D offers a reliable solution for linear motion applications requiring high-speed capabilities and precision without succumbing to distortion or misalignment issues commonly associated with less robust systems.
