Thompson Coupling

The Thompson constant velocity coupling is the worlds first and only constant velocity joint with no load bearing sliding surfaces. Unlike other CV joints (constant velocity joints), this one does not have any load bearing - sliding surfaces, instead it uses a unique arrangement of roller bearing hinges. The roller bearings create a fluid movement with reduced friction, which translates to less wear and tear and greater efficiency. The joint has a unique centring device made up of a spherical 4-bar linkage that centres and orientates the hinge joint. The joint is able to cope with greater loads, making it suitable for heavy-duty applications such as helicopter rotor heads, rear wheel and front wheel drive systems and many other types of machinery.
