The MJB-55-EWH is a jaw type flexible coupling designed for high torque transmission, making it suitable for applications such as machine tool spindles. It features a polyurethane sleeve that provides excellent flexibility, allowing it to accommodate eccentricity, angular misalignment, and twisting vibrations. The coupling is constructed from S45C steel with a ferrosoferric oxide finish, ensuring durability and resistance to wear. It has a rated torque of 28 N¬?m and a maximum torque of 70 N¬?m, with a maximum rotational frequency of 17,000 min,Ū¬p. The allowable operating temperature ranges from -20°C to 60°C. This coupling is compatible with servomotors, stepping motors, and general-purpose motors, offering various assembly options for ease of installation and maintenance. The MJB-55-EWH is particularly noted for its electrical insulation properties, with a resistance value of not less than 2 MΩ.
