1. Ball-cage constant velocity joint (cv joint) for industrial applications 2. Including fixed type (bj...B \bj...C \bj...D \bj...M\ rf\bj...Cm)and sliding type(doj...C\ doj...F\ htj...C\ htj...Jd\ htj...Z\ bc...F\ bc...P\dox...F\dos...F\ ql). 3. Work angles are between 0¡ã and 75¡ã . 4. The cv joints rotational speed can be transmitted at constant velocity, 5. High transmission efficiency, 6. Compact structure, small footprint, and have the ability to absorb vibration and shock, high precision dynamic balance. 7. In special situation, it can be added to the overload protection. 8. The cv joint have greater torque capacity, the max. Torque up to 1010000n. M.
