The Bosch Rexroth BALL TRANSFER UNIT KU-B30-MFG (R053013010) is a compact and highly functional ball transfer unit designed for general applications where smooth and precise movement of items is required. This unit features a galvanized cover and housing, with balls crafted from antifriction bearing steel, ensuring durability and reliability in operation. The KU-B30-MFG model comes equipped with a felt seal and is pre-lubricated, offering protection against contaminants and reducing maintenance needs. With a nominal size of 30, the unit's outer diameter D measures precisely for seamless integration into various systems. It boasts an impressive static load rating C, indicating its capability to handle significant weight without compromising performance. The ball transfer unit operates effectively within a temperature range from a minimum operating temperature to a maximum of C. However, it is important to note that at temperatures above C, units without a felt seal should be utilized, and load capacity may be reduced. For applications requiring movement at higher speeds, the KU-B30-MFG can sustain a maximum permissible linear speed vmax. Users should be aware that prolonged use at speeds above 1 m/s could lead to increased temperatures and potentially affect the service life depending on the load applied. In such scenarios, high-temperature lubricants are recommended following the manufacturer's guidelines. The ball transfer unit's design includes an extremely small footprint for easy installation in tight spaces while providing versatile functionality. Its dynamic load capacity C further highlights its ability to support dynamic forces during operation. Weighing in at just 0 kg, this Bosch Rexroth ball transfer unit combines lightweight construction with robust performance. It's an ideal choice for facilitating multi-directional motion in material handling systems and various other applications requiring precision movement with minimal effort.
