The Bosch Rexroth BALL TRANSFER UNIT KU-C8-P-OFK (R053120810) is a meticulously designed component for facilitating smooth and precise material handling across various applications. This ball transfer unit is particularly adept at transporting sensitive materials such as glass, polished aluminum, brass, and steel sheets due to its construction featuring a load ball made from plastic (PA), which minimizes the potential for damage to delicate surfaces. The unit's all-galvanized parts and balls crafted from corrosion-resistant steel ensure longevity and consistent performance in challenging environments. The KU-C8-P-OFK model is distinguished by its lack of a felt seal, which simplifies preservation while maintaining efficient operation. Its notable specifications include an outer diameter D and a nominal size that allows for integration into various system designs. The maximum operating temperature is indicated with a prefix and suffix, with an explicit footnote advising on dynamic load capacity C at the specified temperature. Furthermore, users are reminded to account for reduced load capacity when operating above certain temperatures. With its static load rating C and dynamic load capacity C clearly defined, this ball transfer unit provides reliable support within its operational parameters. The product also specifies the maximum permissible linear speed vmax, alerting users that prolonged use at speeds above 1 m/s could lead to increased temperatures and reduced service life contingent on the applied load. Weighing in at just 0.1 kg, the Bosch Rexroth BALL TRANSFER UNIT KU-C8-P-OFK is light yet robust, making it an excellent choice for systems requiring precise movement control without adding significant weight. Its design ensures that it can be seamlessly incorporated into existing setups or used as part of new installations where material handling efficiency is paramount.
