Zero-Max customised high-torque couplings

Customised high torque CD couplings up to 50 cm in diameter handling 78,000 Nm peak torque are now available from Zero-Max. Available to system designers seeking the most robust coupling for extremely large and challenging applications, these ‘super-sized’ couplings combine highest torsional stiffness and high load capacity.

With torsional stiffness of 419,000 Nm/deg and continuous torque of 39,000 Nm, these CD couplings have angular misalignment capacity of 1.5° with axial misalignment of 6.5 mm and parallel misalignment of 0.24 mm.

Designed around a composite centre disk, super-sized CD couplings perform at these peak torques in the most hostile operating environments - from extreme cold to hot weather conditions (-57 to +121°C). Applications include drive trains, gear boxes and generators providing trouble-free operation in seawater and abrasive desert sand conditions.

The hub material is 1045 HR steel with fasteners made of titanium 6AL4V grade 5 materials. All components are tested with finite element analysis (FEA) software for predictable characteristics.
