 | 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. |
