The Bosch Rexroth SUPER LINEAR BUSH (R067022040) is a high-performance linear bushing designed for smooth and precise linear motion. This model, part of the Super LB A series, features a self-aligning capability that compensates for shaft deflection and misalignment, ensuring reliable operation even in challenging conditions. The closed design with shaft diameter d is equipped with two seals for enhanced protection against contaminants. Constructed from steel bearing plates with meticulously machined ball guide grooves and optimized ball lead-in chamfers, the SUPER LINEAR BUSH ensures exceptionally smooth travel and an extended service life. It boasts a high travel speed of up to m/s, although it should be noted that at this velocity, the service life may be limited due to increased wear on plastic parts. The bushing's dynamic load capacities are impressive, based on a total travel distance of 100 km—when calculations are based on 50 km, these values should be adjusted by multiplying by 1.26. The product can operate within an ambient temperature range of -20°C to +80°C, accommodating various environmental conditions. Additionally, the SUPER LINEAR BUSH has been tested for total travel distances ranging from 10^4 m to 10^7 m without failure. The outer diameter D and breakaway force are specific to this model code, as well as the friction coefficient which ranges from 0.01 under heavy load conditions to a maximum of 0.25. It also includes integrated wiper seals made from PA or POM materials that contribute to its low friction force during operation without radial load. This linear bushing is suitable for applications requiring precise linear guidance with the ability to handle significant loads and speeds while maintaining accuracy over long periods of use. Its design ensures easy installation and minimal maintenance requirements, making it a reliable choice for various linear motion applications.
