Magnaloy_Flexible Drive Coupling

Magnaloy is the original lightweight, heavy-duty flexible-drive coupling. Magnaloy couplings are manufactured from magnesium material which is 76% lighter than cast iron and 36% lighter than alu­minum.

Close matching tolerances assures vi­bration-free operation without need for special tools. Solid magnesium alloy sand castings are heat treated and offer the highest strength-to-weight ratio avail­able. Both clamp and spline type cou­plings are available.
