DOF ball cage universal joint, high torque, large load capacity, space saving, high 

flexibility, high speed, low noise, easy to disassemble.

What is the difference between DOF cage universal joint and SWC, SWP cross axis

 universal joint?

The main differences are as follows:

1. DOF has buffering and damping properties, can reduce noise, and automatically circulates lubrication;

2. Under the same rotation diameter and inclination angle, the bearing capacity can be increased by 0.5-1 times;

3. Good synchronization, even with a single ball joint plunger universal joint, can ensure synchronization;

4. The initial compensation for axial x and radial y is relatively large, especially for axial x, which can be achieved without the need 

for external splines;

5. Novel structure, light weight, good processability, easy mass production, and cost reduction;

6. Reliable work, easy assembly and disassembly, convenient maintenance, long service life, not only for low-speed heavy load and

 conventional speed working conditions of the shaft system
