What is the best coupling for high speed?
Diaphragm coupling
Diaphragm couplings are great all-rounder shaft couplings. They can accommodate parallel misalignment as well as high angular and axial misalignment.
They also have high torque capabilities and can transmit torque at high speeds without the need for lubrication.
What to consider when buying a coupling?
Application variables.
Shaft misalignment.
Lubrication requirements.
Operating environment.
