Auniversal joint, (universal coupling,U-joint,Cardanjoint,Hardy-Spicerjoint, orHooke’s joint) is ajointorcouplingin a rigid rod that allows the rod to ‘bend’ in any direction, and is commonly used in shafts that transmitrotary motion. It consists of a pair ofhingeslocated close together, oriented at 90° to each other, connected by a cross shaft. The universal joint is not aconstant velocity joint.

Features of WSS universal joint:

1.Applicable to all kinds of general mechanical situation,max rotate speed reach 4000r/min.

2.Stretch type,connects long distance between shafts

3.Max ratation angle can be 45o

4.Have single-jointed type and double type

5.Fast locking is aviable

6.Available in your choice of round, hex, splined, or keyway bore
