The Bosch Rexroth BALL TRANSFER UNIT KU-C15-OFK (R053021510) is a highly efficient component designed for facilitating smooth and precise movements of goods in various material handling applications. This ball transfer unit is notable for its extremely small size and the absence of a felt seal, which makes it suitable for general purposes where a compact solution is required. The unit features all parts galvanized, including a sheet steel housing, ensuring durability and resistance to corrosion. The balls are made from corrosion-resistant steel, enhancing the unit's longevity even in challenging environments. With an outer diameter (D) that supports ease of integration into systems, the KU-C15-OFK can withstand static loads effectively with its robust static load rating (C). It operates within a temperature range from minimum to maximum degrees Celsius, allowing use in various climatic conditions. For high-temperature applications above 100°C, it is recommended to use bright metal ball transfer units without a felt seal and to consider the reduction in load capacity due to elevated temperatures. High-temperature lubricant should be applied as per the manufacturer’s instructions, possibly requiring removal of existing lubricant oil. The dynamic load capacity (C_dyn) underscores the unit's capability to handle loads while in motion. Care should be taken when operating at linear speeds above 1 m/s as this may lead to increased temperatures and reduced service life depending on the load. Its nominal size and weight make it an unobtrusive yet effective component for systems requiring precise movement control. In summary, the Bosch Rexroth BALL TRANSFER UNIT KU-C15-OFK offers versatility and reliability for applications necessitating easy maneuverability of items with minimal effort while maintaining structural integrity under various operational conditions.
