The Bosch Rexroth BALL TRANSFER UNIT KUM-A12-HB-OFK (R053370200) is a high-quality component designed for facilitating smooth and precise movements in material handling systems. This ball transfer unit features a solid steel housing with a bright metal finish and a high collar design, ensuring durability and robust performance. The balls are made from antifriction bearing steel, which allows for very smooth running and effective load distribution. This particular model is notable for its absence of a felt seal, which makes it suitable for operations in environments where the maximum operating temperature can reach high levels. It is important to note that at temperatures above 100°C, the use of bright metal ball transfer units without a felt seal is recommended to maintain integrity and performance. Users should also consider the reduction in load capacity at higher temperatures and ensure the use of high-temperature lubricants as per the manufacturer's instructions. With an outer diameter (D) that provides stability and an impressive static load rating (C), this ball transfer unit is capable of handling significant weights while maintaining ease of movement. It has been engineered to operate within a specific temperature range, with both minimum and maximum operating temperatures defined by the manufacturer to ensure optimal functionality. The dynamic load capacity (Cdyn) also takes into account operating temperature limits, especially for applications over 100°C, where users must follow guidelines regarding lubrication and load adjustments. For applications that involve prolonged periods of use at speeds above 1 m/s, users should be aware that an increase in temperature could result in a reduction in service life depending on the load. Weighing only 0.25 kg with a nominal size of 22 mm, this ball transfer unit integrates seamlessly into various systems requiring precise movement control without adding significant weight or bulk. Its construction with antifriction bearing steel balls ensures longevity and consistent performance even under demanding conditions.
