The Bosch Rexroth SUPER LINEAR BUSH KBB-16-D (R067211640) is a high-quality linear bushing designed for smooth and precise linear motion. This particular model is part of the Super LB B series, which is characterized by its closed design, lack of self-alignment features, and integration of a single seal. It is engineered to transfer lower tipping forces along the axial direction while maintaining high travel speeds of up to 5 meters per second. The KBB-16-D is crafted with steel bearing plates that have meticulously machined ball guide grooves and optimized ball lead-in chamfers, ensuring an exceptionally smooth travel experience and a long service life. The bushing's design incorporates a ball retainer and outer sleeve made from durable materials such as PA or POM, while the balls themselves are constructed from rolling bearing steel. This model does not require initial lubrication, reducing maintenance needs upon installation. It operates efficiently within a permissible ambient temperature range of -20°C to +80°C. The Bosch Rexroth SUPER LINEAR BUSH KBB-16-D boasts impressive specifications such as a maximum dynamic load capacity (Cmax), maximum acceleration (amax), and features friction coefficients that vary depending on the presence of seals and lubrication conditions. The product's breakaway force and radial clearance are carefully calibrated to ensure reliable performance under various load conditions. With its low friction coefficient ranging from 0.01 to 0.025, the KBB-16-D facilitates energy-efficient operation even at high speeds, although it should be noted that continuous operation at maximum speed may limit service life due to increased wear on plastic parts. Nevertheless, tests have demonstrated significant total travel distances without failure, highlighting the bushing's durability. This linear bushing weighs approximately 0.1 kg and comes with radial clearance specifications that cater to different shaft tolerances. The Bosch Rexroth SUPER LINEAR BUSH KBB-16-D is an ideal choice for applications requiring precise linear guidance without self-alignment capabilities.
