Shaft Couplings in the NHC series vary in size at both ends but use the same operating pressure to eliminate the risk of wrong pressure.
Uniquely designed ends ensure correct operation.
Bolts are tightened with the help of the new HyFit Nut, so it can be retrofitted to existing coupling bolts and used with the HyFit system.
■ Simple and convenient assembly and disassembly;
■ No keyway and thrust ring are required on the shaft;
■ The stress on the entire contact surface is relatively uniform, and the stress concentration is not obvious;
■ When the vibration load of the shaft system changes, the shaft will not be worn;
■ The position of the coupling on the shaft is easy to ensure, and the connection accuracy is high;
■ Can be used repeatedly, with high interchangeability
