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
