The Bosch Rexroth BALL TRANSFER UNIT KU-C30-MFG (R053023010) is a highly efficient and versatile component designed for facilitating smooth and easy movement of goods in various material handling applications. This ball transfer unit is characterized by its extremely small size, making it suitable for general applications where space is at a premium. It features all parts galvanized, including balls made from corrosion-resistant steel, ensuring durability and longevity even in challenging environments. The KU-C30-MFG is equipped with a felt seal, providing lubrication that contributes to the unit's low friction and ease of movement. The sheet steel housing that encapsulates the unit offers additional protection and structural integrity. With an outer diameter (D) specification, the ball transfer unit can support a static load rating (C), which speaks to its ability to handle substantial weight without compromising performance. One of the key capabilities of this ball transfer unit is its ability to operate within a temperature range of °C to °C. However, it should be noted that at temperatures above °C, bright metal ball transfer units without a felt seal are recommended due to potential reductions in load capacity. For high-temperature applications, users are advised to employ high-temperature lubricant and follow the manufacturer's instructions carefully, which may include washing out existing lubricant oil. The dynamic load capacity (C) of the KU-C30-MFG further illustrates its suitability for various dynamic applications where loads are frequently moved or reoriented. The maximum permissible linear speed (vmax) indicates its capability to handle fast-paced operations; however, prolonged use at speeds above 1 m/s could lead to increased temperature and reduced service life depending on the load. With its nominal size and tolerance specifications provided for critical dimensions such as D and dW, this Bosch Rexroth ball transfer unit is precisely engineered for reliable performance in diverse material handling setups. The weight specification also ensures that users can account for the unit's mass when designing systems or calculating load distributions.
