Cross groove Fixed Joint (CFJ)

NTN Fixed Type CVJ “CFJ”

CVJs suffer from a greater torque loss ratio as the operating angle increases, however the developed product uses a proprietary spherical cross groove structure to drastically reduce internal frictional forces and decrease the torque loss ratio over a wide range of operating angles.
A reduction in temperature increases at high rotational speeds also allows it to be used for propeller shafts.​
