The Bosch Rexroth BALL TRANSFER UNIT KU-N22-MFG (R053062200) is a highly efficient and robust ball transfer unit designed for general applications requiring smooth and precise movement of goods. This unit is particularly small, making it suitable for use in tight spaces where larger units cannot be accommodated. The entire unit, including balls, is made from corrosion-resistant steel, ensuring durability and a long service life even in harsh environments. Featuring a felt seal that is pre-lubricated, the KU-N22-MFG offers low friction movement and protection against contaminants, which can extend the operating life of the unit. It comes with a sheet steel housing that provides additional strength and stability to the assembly. The outer diameter D of the ball transfer unit allows for integration into various systems without significant modifications. Capable of withstanding static loads as indicated by its static load rating C, this ball transfer unit can handle significant weight without deformation or failure. However, it's important to note that when operating at linear speeds above 1 m/s, an increase in temperature and reduction in service life may occur depending on the load. The KU-N22-MFG operates effectively within a temperature range specified by the manufacturer but requires special considerations at higher temperatures. Above 100°C, it is recommended to use bright metal ball transfer units without felt seals and apply high-temperature lubricants according to manufacturer instructions. With its nominal size and precise tolerances, this Bosch Rexroth ball transfer unit is engineered for reliability and performance in facilitating multidirectional movement within various systems. Its lightweight design does not compromise on its ability to support dynamic loads effectively as per its dynamic load capacity C specification.
