The Bosch Rexroth BALL TRANSFER UNIT KU-N12-OFK (R053061200) is a compact and robust component designed for various material handling applications where multidirectional movement is required. This ball transfer unit is specifically engineered without a felt seal, featuring all parts made from corrosion-resistant steel, which ensures durability and longevity even in harsh environments. The unit comes with a sheet steel housing and is preserved to maintain its quality over time. With its extremely small size, the KU-N12-OFK model is well-suited for general applications where space constraints are a concern. It boasts an outer diameter (D) that allows for seamless integration into machinery or conveyor systems. The unit's static load rating (C0) indicates its capacity to withstand stationary loads without deformation or failure. The dynamic load capacity (C) of this ball transfer unit reflects its ability to handle loads while in motion. It has been designed to operate effectively within a temperature range of -30°C to +70°C, making it versatile for use in various operating conditions. For applications that involve temperatures above +70°C, it is recommended to use bright metal ball transfer units without a felt seal to accommodate the increased thermal conditions. When operating at higher speeds above 1 m/s, users should be aware that there may be an increase in temperature and a potential reduction in service life depending on the load being carried by the unit. The nominal size and tolerances are precisely defined, ensuring consistent performance and ease of installation. Weighing only 0.02 kg, the Bosch Rexroth BALL TRANSFER UNIT KU-N12-OFK maintains a low profile while providing reliable and efficient material handling capabilities. It's an ideal solution for enabling smooth and controlled movement in multiple directions across various industries requiring precise positioning and transportation of goods.
