Overview
The Magnaloy 370 flexible drive coupling hub is a precision-engineered component designed for reliable mechanical power transmission in industrial applications. This magnesium alloy hub is part of Magnaloy Coupling Company’s premium line of flexible drive couplings. The lightweight construction of the Magnaloy 370 makes it ideal for systems where weight reduction is critical while maintaining high torque capacity and durability. The load-lock design ensures secure engagement between mating components, providing smooth operation across a wide range of speeds and load conditions.
Key Features
- Magnesium alloy construction for exceptional lightweight performance
- Load-lock hub design for secure component engagement
- Flexible construction accommodates minor shaft misalignment
- Superior corrosion resistance compared to standard steel couplings
- Compatible with standard drive coupling inserts and complementary hubs
Technical Specifications
The Magnaloy 370 hub is manufactured to precision standards suitable for integration into flexible drive coupling assemblies. Specific bore sizes, keyway configurations, and torque ratings are available in standard and metric options. This hub works in conjunction with compatible inserts and mating hubs to form complete coupling assemblies rated for demanding industrial duty.
Typical Applications
- Pump and motor drive connections in process industries
