The cross-shaft universal coupling has the following characteristics:

1. Comparing with other types of universal couplings with high load-carrying capacity, it can transmit more torque under the same rotating diameter, which is more important for mechanical equipment whose rotating diameter is strictly limited.

2. High transmission efficiency and high transmission efficiency can reach 98.7-99.9%. It can save energy for high-power transmission and reduce power consumption by 5-15%.

3. Smooth transmission and low noise used in rolling mill transmission can improve rolling quality, machine performance and operator's working conditions. The general noise is 30-40 DB (A);

4. Reasonable structure, reliable use and long service life;

5. The allowable inclination angle is large, up to 10-25 degrees.
