Overview
The Magnaloy M30002806 is a Model 300 standard hub coupling designed for flexible power transmission in industrial machinery. The 300 Series Magnaloy coupling is the original lightweight, heavy-duty flexible drive coupling. This unit features a 7/8 inch bore with a 3/16 inch keyway, delivering reliable shaft connection with minimal runout.
Key Features
- Lightweight magnesium construction makes Magnaloy couplings 76% lighter than cast iron and 36% lighter than aluminum units and they’re stronger than either.
- Close machining tolerances (TIR of .002″) assure vibration-free operation and easy, accurate alignment without need for special tools.
- Reduced loads on bearings, shafts and pumps, for longer component life.
- Rust proof and corrosion resistant.
- The Premium Line of Magnaloy Couplings comes standard with a single set-screw over the keyway.
