Shaft connections for high performances
The GripLoc system is capable of safely transferring high forces (torques and axial forces) in the smallest installation space. Furthermore, the system is easily and rapidly installed and just as easy to disassemble again even after prolonged and intensive stress.
GripLoc operates according to the principle of a radial shrinkage connection, but without the serious disadvantages of this type of connection.
