The Bosch Rexroth BALL TRANSFER UNIT KU-N15-OFK (R053061500) is a highly durable and efficient component designed for smooth and precise material handling applications. This ball transfer unit is part of the product group identified by ID Size b, specifically tailored for general applications where a small, corrosion-resistant unit is required. The entire assembly, including balls, is made from corrosion-resistant steel, ensuring longevity and reliability even in challenging environments. With its extremely small form factor and sheet steel housing, this unit facilitates easy movement of goods and materials with minimal effort. It features a nominal size of Nominal size, an outer diameter D of Size D with a tolerance of Tolerance D prefixprefix.suffixsuffix, and operates within a temperature range from Minimum operating temperature prefixprefixsuffixsuffix°C to Maximum operating temperature prefixprefixsuffixsuffix°C. For high-temperature applications above 100°C, it's important to use bright metal ball transfer units without felt seals to maintain functionality. The BALL TRANSFER UNIT KU-N15-OFK boasts an impressive static load rating C of Static load rating C and a dynamic load capacity C of Dynamic load capacity C. The maximum permissible linear speed vmax highlights the unit's capability to handle fast-paced operations; however, it should be noted that prolonged use at speeds above 1 m/s may lead to increased temperatures and reduced service life depending on the applied load. Weighing in at Weight kg, this ball transfer unit is both lightweight and robust. It has been engineered without a felt seal for preservation purposes but requires the use of high-temperature lubricant for optimal performance at elevated temperatures. Users must adhere to Bosch Rexroth's instructions when operating this unit, especially when considering lubrication maintenance or replacement in order to ensure peak performance and durability over time.
