We are offering Automobile U Joints.U Joint is an all metal coupling between 2 Shafts, allowing for radial and axial misalignment and simultaneously transmitting torque, even at variable speeds. These couplings have the ability to transmit power even at high working angles ( upto 45 )in a minimal amount of space Originally claimed to have been designed by an Italian mathematician-Geronimo Cardano ( the British declaring that Hooke had designed this, earlier). Hence, also known as Cardon Shafts/Hookes Joints . In earlier designs, this joint appeared to have the construction of balls and was also known as Ball Joint.
