Overview
The Magnaloy M30002806 is a Model 300 flexible drive coupling hub manufactured by Magnaloy Coupling Company, a leading producer of lightweight, precision drive couplings since 1956. This hub features a 7/8″ bore and 3/16″ keyway, making it ideal for connecting hydraulic pumps, motors, and industrial drive equipment. The solid magnesium alloy construction provides exceptional strength-to-weight performance while maintaining tight machining tolerances for reliable, vibration-free operation.
Key Features
- Magnesium alloy construction—76% lighter than cast iron, 36% lighter than aluminum, yet stronger than both
- Close machining tolerances (TIR .002″) ensure vibration-free alignment without special tools
- Heat-treated solid magnesium alloy permanent mold castings for maximum durability
- Standard single set-screw design over keyway; optional double set-screw configurations available (DSS45/DSS90)
- Corrosion-resistant and rust-proof for long service life
- Reduced bearing and shaft loads, extending component lifespan
