The Bosch Rexroth SUPER LINEAR BUSH KBB-O-25-DD (R067322540) is a high-quality linear bushing designed for precise linear movements in various applications. This open-type linear bushing features steel bearing plates with meticulously machined ball guide grooves and optimized ball lead-in chamfers, ensuring exceptionally smooth travel and a long service life. It is equipped with two seals but does not incorporate a self-alignment feature, making it ideal for transferring lower tipping forces along the axial direction. With its ability to handle high travel speeds of up to 5 meters per second, the KBB-O-25-DD offers dynamic load capacities that are suitable for the main direction of loading. The bushing's maximum acceleration is noted at 50 m/s², and it operates efficiently within an ambient temperature range of -20°C to 80°C. The outer diameter of size E is specified, and the bushing can achieve a breakaway force of 0.5 N. The friction coefficient ranges from 0.01 to 0.02, indicating minimal resistance under load conditions when lubricated with oil. Furthermore, the static load rating C₀ emphasizes the unit's capacity to withstand static forces without deformation or damage. This model boasts an integrated longitudinal seal alongside optional wiper seals that protect against contaminants, enhancing longevity and performance reliability. Constructed with a ball retainer and outer sleeve made from PA or POM materials, as well as balls crafted from rolling bearing steel, it requires no initial lubrication. The SUPER LINEAR BUSH KBB-O-25-DD is lightweight at just 0.1 kg and provides various radial clearance options for shaft-bore configurations, ensuring compatibility with diverse setup requirements. Its design facilitates use on fully supported shafts where precision is critical and where other linear guides may fail due to suboptimal substructures. Overall, this product stands out for its low-cost yet high-performance capabilities in linear motion applications requiring clean operation environments and precise guidance without significant radial loads.
