The Bosch Rexroth BALL TRANSFER UNIT KU-B15-OFK (R053011510) is a highly efficient and versatile component designed for facilitating smooth and easy handling of goods in various conveyor systems. This ball transfer unit features a galvanized cover and housing, with balls crafted from antifriction bearing steel, ensuring durability and a long service life. The unit is particularly notable for its extremely small size, making it suitable for general applications where space is at a premium. The KU-B15-OFK model operates effectively within a temperature range of -30°C to +70°C without the need for a felt seal, which makes it ideal for environments where temperatures can fluctuate significantly. When operating at temperatures above 70°C, it is recommended to use bright metal ball transfer units without felt seals to accommodate the higher thermal conditions. It's important to consider that at these elevated temperatures, there should be an allowance made for the reduction in load capacity and the use of high-temperature lubricants as per the manufacturer's instructions. With an outer diameter (D) of 22 mm and nominal size tolerance precision, this ball transfer unit can sustain a static load rating (C0) while maintaining a maximum permissible linear speed (vmax). Users should note that prolonged use at speeds above 1 m/s may lead to an increase in temperature and consequently affect the service life depending on the applied load. The product has a dynamic load capacity (C) that ensures effective operation under varying conditions. The weight of this compact unit is 0.07 kg, which makes it light enough to be incorporated into systems without adding significant mass. In summary, the Bosch Rexroth BALL TRANSFER UNIT KU-B15-OFK (R053011510) is an essential component for any application requiring reliable material handling with minimal space requirements while offering flexibility across different temperature ranges and operational demands.
