1.The detail description of Universal joint

Material:
Normally we are using 20Cr or 20CrMnTi gear steel, as chinese standarded

alloy steel for the cross spider of our universal joint cross assembly and the

glove bearing is also based on such material. Also we can make the u-joint as

you requested material when the quantity is acceptable for production lot. For

the needle roller, the material will be GCr15 bearing steel. High-quality materials

are used for our accessarries such snap ring, NBR seal rings, straight or

jointed hydraulic grease nipples, and general purpose lithium base grease for

automobile.



Application:
A power transmission universal joint cross assembly is widely used in automobile types including: middile and high end salon, off-road vehicles, most of the trucks, agriculture machinery, mine and heavy-duty machine, specifical purpose vehicles.

Structure:
A universal joint has four needle roller bearings that provide the strength and life which is most important and both the axes of the spider are inserted into two yokes. In the bearing, a seal is located to prevent dust, water, etc.from ingress and to prevent grease egress. For heavy duty vehicles with high torque transmission, such as large size vehicles and various industrial machine vehicles, a wing type (3 kinds: block, wing, delta) is used. Bolt-fastening mechanism and key-way are incorporated to the bearing and a precise circle is on its back. By receiving the torque through the key-way, even if a bolt is loosely tightened, the shearing stress does not apply to the bolt.

3.The advantage of Universal joint
A universal joint is fitted between the driveshaft and the differential axle to transmit power through the axis of rotation. Perfectly smooth rotation is required, in order to handle the constantly changing angles of the rear axle caused by the vertical movement of uneven surfaces transmitted through the suspension system. In other words, a universal joint efficiently transmits power through both fixed and fluctuating angles. Moreover, since the universal joint is lightweight and compact with superior durability, it has proved to be a safe and positive product for power transfer in Automotive and Industrial applications. In recent years, we have been working to develop and produce the press type bearing which is aimed at improvement in intensity and durability and reduces cost further.
