Although we don't often hear about universal joints, we should have heard of universal joints. Universal joints are universal joints. The precision universal joint is a subdivision of the universal joint, that is, a kind of universal joint.

The precision universal joint is suitable for transmission occasions with two shafts β≤45º on the same plane of the connection space, and transmits the nominal torque of 11.2-1120N.m.The WSD type of the precision universal joint is a single-section precision universal joint, and the WS type is a double-section precision universal joint. And the maximum included angle between each section is 45 degrees;. The finished hole H7 can be provided with keyway, hexagonal hole and square hole according to requirements. Allow the angle between the two shafts to be changed within a limited range as the work needs. There are two types with sliding bearing and needle bearing, according to user requirements. With needle roller bearings, the dynamic load is high, the bearing clearance is small, the maximum speed can reach 4000rpm, and the maximum speed with sliding bearings is 1000rpm.

For precision universal joints, it was not our country that was manufactured in the first place, so our country is still struggling to catch up with the manufacturing technology of precision universal joints. However, in the manufacture of precision universal joints, the universal joint manufacturer have indeed made a lot of effort.
