Compared with the cross axis universal joint, the ball cage universal joint of 

Maidong Industry has the following characteristics:

(1) Has buffering and vibration reducing 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
