The Bosch Rexroth BALL TRANSFER UNIT KU-B22-P-MFK (R053112210) is a high-quality ball transfer unit designed for the smooth and efficient handling of sensitive materials. This unit features a load ball made from plastic (PA), specifically engineered to transport delicate items such as glass, polished aluminum, brass, and steel sheets without causing damage or abrasion. The galvanized cover and housing ensure durability and resistance to corrosion, while the balls made from antifriction bearing steel provide reliable movement. With its dry felt seal, the BALL TRANSFER UNIT KU-B22-P-MFK is preserved to maintain cleanliness and reduce the ingress of contaminants. This seal contributes to the unit's suitability for environments where purity is essential. The outer diameter of this model is D, which allows for integration into various systems. The dynamic load capacity C of this ball transfer unit can withstand conditions up to a maximum operating temperature of C without compromising performance. However, it's important to note that at temperatures above C, users should expect a reduction in load capacity. Similarly, when operating at linear speeds above the maximum permissible speed vmax, there may be an increase in temperature and a decrease in service life depending on the load. This model has a static load rating C and operates efficiently within a temperature range of min...max C. For applications requiring prolonged use at higher speeds or temperatures, allowances should be made for potential reductions in capability. Weighing . kg and with a nominal size of , the BALL TRANSFER UNIT KU-B22-P-MFK is compact yet robust enough to handle various material handling tasks while ensuring that sensitive products are transported safely and effectively.
