- Magnet assemblies are made up of steel parts and a ceramic magnet, bonded together with epoxy. - Max pull is tested on a ½� thick and flat machined steel plate. But the actual pull should be much smaller if your steel is thinner, rough, rusty, coated or not very flat. For any critical applications, three-time safety factor is strongly recommended. - Besides standard models listed bellow, we can make assemblies based on custom designs. - Applications include magnetic holding, lifting, antenna mounting, positioning, retrieving and more.
