The Bosch Rexroth SUPER LINEAR BUSH KBB-O-20 (R067302000) is a high-quality, low-cost linear bushing designed for smooth travel and long service life. This open linear bushing is suitable for fully supported shafts and excels in applications where precision is key, and there's potential for other guides to warp due to suboptimal substructures. The steel bearing plates feature meticulously machined ball guide grooves and optimized ball lead-in chamfers, ensuring seamless movement. The KBB-O-20 does not include a self-alignment feature, which means it can transfer lower tipping forces along the axial direction. It boasts a high travel speed capability of up to 5 meters per second, although this may limit the service life due to increased wear on plastic components. Testing has indicated that total travel can range from 100 km to 1000 km without failure under specified conditions. This model comes without seals, which simplifies its design while still providing dynamic load capacities suitable for the main direction of loading. Its static load rating is substantial, ensuring reliable operation under static conditions. The bushing's balls are made from rolling bearing steel, and the ball retainer and outer sleeve are constructed from either PA or POM materials. The SUPER LINEAR BUSH KBB-O-20 operates effectively within an ambient temperature range of -30°C to +80°C. It has a defined breakaway force necessary to initiate motion and features friction coefficients that vary depending on load and lubrication conditions. With a weight of just 0.2 kg, it offers an efficient solution for various linear motion applications without compromising on performance or durability. The product group ID for this item is specific to its characteristics as an open format linear bushing with dynamic load capacity considerations. Overall, the Bosch Rexroth SUPER LINEAR BUSH KBB-O-20 (R067302000) represents a robust option for those in need of reliable linear motion guidance with high-speed capabilities and without the necessity for initial lubrication or complex sealing systems.
