- Couplings & Collars
Diaphragm Coupling D26L35
One of the main benefits of using diaphragm couplers instead of standard flexible couplers is that there is significantly less backlash, as well as drastically increasing the resolution and repeatability of the system.
Diaphragm couplers are also designed to have noise reduction and vibration compensation. The vibration compensation increases the lifespan of the mechanical hardware used on the transmission system.
