The Bosch Rexroth BALL TRANSFER UNIT KUS-B22-MFG (R053512210) is an advanced conveying solution designed to facilitate the easy and smooth movement of heavy loads. This ball transfer unit features a robust reinforced steel housing with a galvanized cover, ensuring durability and resistance to impact loads. The balls are crafted from high-quality antifriction bearing steel, providing reliable performance under demanding conditions. With its felt seal, the KUS-B22-MFG is pre-lubricated for immediate use and offers protection against contaminants, extending the service life of the unit. It has been engineered to operate within a temperature range of -30°C to +70°C, accommodating various environmental conditions. However, for applications exceeding 70°C, units without a felt seal should be employed alongside high-temperature lubricants as per manufacturer guidelines. The unit boasts an outer diameter (D) that allows for maximum permissible linear speeds (vmax), ensuring efficient operation while maintaining stability. Users should note that prolonged use at speeds above 0.5 m/s may result in increased temperatures and reduced lifespan depending on the load applied. Bosch Rexroth has designed this ball transfer unit with a static load rating (C) and dynamic load capacity (Cdyn), indicating its suitability for handling heavy weights while maintaining smooth motion. The product's nominal size and tolerances are meticulously specified to guarantee compatibility with various installation requirements. Weighing in at just 0.4 kg, the KUS-B22-MFG is both lightweight and compact, making it an ideal choice for systems where space is at a premium but performance cannot be compromised. Whether used in material handling systems or as part of a larger conveyor assembly, this ball transfer unit from Bosch Rexroth stands out as a reliable component that can significantly enhance operational efficiency.
