The Bosch Rexroth SUPER LINEAR BUSH (R067002500) is a high-quality linear bushing designed for smooth travel and long service life. This model, KBA-25, features a closed format without seals and boasts a self-alignment feature that compensates for shaft deflection and misalignment. It is engineered to handle high travel speeds of up to 5 meters per second, although the service life may be limited by increased wear on plastic parts at these higher speeds. Constructed with steel bearing plates that include machined ball guide grooves and optimized ball lead-in chamfers, it ensures exceptional smoothness in movement. The balls are made from rolling bearing steel, which contributes to the bushing's durability and performance. The KBA-25 can operate within an ambient temperature range of -10°C to 80°C and has an outer diameter of D = 40 mm. The SUPER LINEAR BUSH KBA-25 is designed with a low-friction coefficient that ranges from 0.01 to 0.25 under lubrication with oil, though this value can increase under lighter loads. It also has an impressive maximum dynamic load capacity (Cmax) while maintaining a minimum dynamic load capacity (Cmin) based on total travel distance. This linear bushing is suitable for applications requiring precise linear motion control where space constraints exist or where shaft alignment cannot be perfectly maintained. Its self-aligning capability allows for flexibility in installation and operation, making it an ideal choice for various mechanical systems requiring robust linear guidance. The product has been tested extensively, demonstrating reliable performance over total travel distances ranging from 100 km to 10,000 km without failure. With its combination of high-quality materials like PA or POM for the ball retainer and outer sleeve as well as rolling bearing steel balls, the Bosch Rexroth SUPER LINEAR BUSH KBA-25 stands out as a dependable component in precision linear motion applications.
