About Magnaloy Coupling
About Magnaloy Coupling
Magnaloy Coupling Company has manufactured precision machined products since 1956, becoming known specifically for its lightweight, heavy-duty flexible drive couplings built from magnesium alloy castings. The company originated the design concept behind its coupling line and has refined the manufacturing process for more than four decades.
Beyond flexible couplings, Magnaloy's catalog includes pump and motor mounts, cylinder rod end alignment couplers, hydraulic manifolds, and reservoirs, positioning the brand as a broader source for drive-train and hydraulic power unit components rather than couplings alone. Magnaloy now operates as a division of Douville Johnston Corporation based in Alpena, Michigan.
Magnaloy's couplings are specified where weight reduction matters alongside durability, such as mobile hydraulic equipment and pump drive assemblies, and the company maintains a distribution network across North America along with dedicated international sales representatives for immediate delivery. ChatMRO indexes the Magnaloy catalog so buyers can search by coupling size, bore diameter, or mount type to find matching parts.

Frequently asked questions
What is Magnaloy best known for manufacturing?
Magnaloy is best known for its lightweight, heavy-duty flexible drive couplings made from precision machined magnesium alloy castings. The company has manufactured these couplings since 1956.
What other products does Magnaloy offer besides couplings?
Beyond flexible couplings, Magnaloy manufactures pump and motor mounts, cylinder rod end alignment couplers, hydraulic manifolds, and reservoirs. This lets buyers source complete hydraulic power unit components from one supplier.
Why are Magnaloy couplings made from magnesium alloy?
Magnesium alloy castings give Magnaloy couplings a lighter weight than comparable steel or cast iron couplings while still handling heavy-duty torque loads. This weight advantage is particularly valued in mobile hydraulic and pump drive applications.
Is Magnaloy still an independent company?
No, Magnaloy now operates as a division of Douville Johnston Corporation, based in Alpena, Michigan. The company has continued manufacturing its coupling and hydraulic component lines under this ownership.
How quickly can Magnaloy products be delivered?
Magnaloy maintains a distribution network across North America along with dedicated international sales representatives, supporting fast delivery of its standard coupling and hydraulic component catalog. This network is a key part of the company's value proposition to distributors.
