The Bosch Rexroth BALL TRANSFER UNIT KU-N30-MFG (R053063000) is a compact and highly durable ball transfer unit designed for general applications where corrosion resistance and smooth movement are essential. This unit features all components made from corrosion-resistant steel, including the balls, ensuring longevity and reliability in various environments. The KU-N30-MFG is equipped with a felt seal that is pre-lubricated, providing additional protection against contaminants while maintaining ease of motion. With its sheet steel housing, this ball transfer unit is not only robust but also capable of withstanding static load ratings effectively. It has an outer diameter D of 15 mm and a nominal size of 30 mm, with precise tolerance levels to ensure optimal performance. The maximum operating temperature range for this unit spans from -30°C to +70°C, making it suitable for a wide range of operating conditions. However, it should be noted that at temperatures above 70°C, units without felt seals should be used instead to accommodate the higher thermal conditions. Designed for applications requiring extremely small yet efficient movement solutions, the KU-N30-MFG has a dynamic load capacity C that supports its use in various dynamic scenarios. The maximum permissible linear speed vmax indicates that caution should be taken when operating at speeds above 1 m/s as this may affect the temperature and service life depending on the load. This ball transfer unit's weight and dimensions are engineered for seamless integration into systems requiring precise material handling capabilities. Furthermore, users are advised to follow Bosch Rexroth's instructions regarding high-temperature lubricants and maintenance procedures to ensure optimal performance over time.
