Palmer Johnson is an authorized distributor for the Airflex ER clutches and brakes. The Airflex ER series elements are used as shaft couplings or holding brakes where engagement occurs at zero speed differential between the element and the drum. The ER series elements are ideal for applications in which a disconnect is required without stopping the prime mover or for applications where the driving and/or driven equipment must be frequently withdrawn from the drive. These elements are offered in 10 sizes with the inside drum diameters ranging from 3 to 24 inches.
Whether you are needing genuine Airflex parts, service manuals or parts lists, or you are wanting one of our factory trained technicians to repair your ER series clutch or brake, we’ve got you covered. Contact the Airflex experts today!
