Magnaloy 400 HUB with Lightweight Design

Discover the original lightweight, heavy-duty flexible drive coupling that revolutionizes the industry. The Magnaloy 400 HUB, with a 1-1/8 bore size and a 3/8 key special, is designed for performance and durability. Engineered with magnesium construction, this hub is 76 percent lighter than cast iron and 36 percent lighter than aluminum units, making it an ideal choice for applications where weight reduction is critical. Key features include: reduced loads on bearings, shafts, and pumps, resulting in longer component life, easier handling, and installation, and rust-proof and corrosion-resistant properties.

Technical Specifications and Properties

The Magnaloy 400 HUB is engineered with precision, offering close machining tolerances (TIR of .002") for vibration-free operation. The solid magnesium alloy permanent mold castings are heat treated, providing the highest strength-to-weight ratio available. This hub comes standard with a single set-screw over the keyway, enhancing shaft gripping forces. Optional double set-screws are available at either 45 degrees or 90 degrees to the keyway, with double set-screws at 45 degrees producing greater forces than those at 90 degrees. For added customization, Magnaloys Clamp feature is also available with bored and keyed hubs, specified by appending a 'C' following the hub part number.
