Automation Techniques, Inc. is your specialized source for Magnaloy Flexible Drive Couplings. We supply the industry’s lightest and strongest vibration-dampening couplings to protect your hydraulic pumps and motors.


Why Choose Magnaloy Couplings from Automation Techniques?
Magnaloy is the world leader in magnesium alloy drive couplings. When your hydraulic system requires precision alignment and superior shock absorption, Magnaloy’s unique construction offers performance that aluminum and cast iron simply cannot match.
- 76% Lighter Than Cast Iron: Magnesium alloy construction drastically reduces the load on bearings, shafts, and pumps, significantly extending the life of your equipment.
- Superior Vibration Dampening: Magnesium has the highest damping capacity of any structural metal, effectively absorbing high-frequency vibrations and noise during operation.
- Exceptional Strength-to-Weight Ratio: Magnaloy couplings are 33% lighter than aluminum yet offer higher strength and better fatigue resistance for heavy-duty industrial cycles.
- Corrosion Resistant: These couplings are inherently rust-proof, making them ideal for harsh environments and diverse fluid power applications.
