The Bosch Rexroth BALL TRANSFER UNIT KU-B30-BL-MFG (R053013110) is a highly efficient component designed for facilitating multi-directional movement of goods and materials. This ball transfer unit features a galvanized cover and housing, with balls crafted from antifriction bearing steel, ensuring durability and smooth operation. The unit is notably compact, making it suitable for applications where space is limited. With a static load rating C and dynamic load capacity C1, the KU-B30-BL-MFG is equipped to handle various loads while maintaining stability and performance. The bottom hole design allows for secure mounting, while the felt seal provides lubrication retention and protection against contaminants, enhancing the longevity of the unit. The ball transfer unit operates within a temperature range of -30°C to +70°C, accommodating a wide array of environments. However, it's important to note that at temperatures above 70°C, units without a felt seal should be used to account for any reduction in load capacity. Additionally, high-temperature lubricant may be required under such conditions following the manufacturer's instructions. With an outer diameter D of 22 mm and nominal size 15 mm, this unit supports maximum permissible linear speeds up to 1 m/s. Users should be aware that prolonged use at speeds above this threshold could lead to increased temperatures and reduced service life depending on the load applied. Weighing in at just 0.1 kg, the Bosch Rexroth BALL TRANSFER UNIT KU-B30-BL-MFG presents itself as an optimal solution for facilitating smooth and controlled motion in various applications without adding significant weight or bulk to the assembly. Its robust construction paired with thoughtful design considerations make it a reliable choice for general use in multi-directional material handling systems.
