Airflex, a Vickers by Danfoss brand (formerly Eaton Airflex). E, EB and ER expanding drum clutches and brakes for slip clutch, tension brake and general power transmission duty, supplied, rebuilt and serviced by Gordon Russell.
Airflex expanding elements use the same rugged tube design as the constricting line, expanding outward to press friction shoes against the inside of a drum. Heat moves quickly to the drum’s outer surface, which makes them excellent for slip clutch and tension brake service. They self-adjust for wear, need no lubrication and work in any plane.
Gordon Russell is an authorized Airflex distributor and service centre in Western Canada, with application help, genuine parts, and rebuild and repair service for all Airflex clutches and brakes.

Construction equipment and marine winches, slip clutches, tension brakes and core expanders, and metalworking, laundry, textile and tire building machines.
Heat moves quickly to the outer surface of the drum, so expanding elements handle the sustained slip of tension brake and slip clutch duty well. They also self-adjust for wear and need no lubrication.
Use the element size from the nameplate or part number (for example 19E475 or 30E600). The size table below links to every listed part for that size: tubes, friction, drums, housings and kits.
Yes. As an authorized Airflex service centre we rebuild expanding elements and supply genuine tubes, friction and kits. Send us the size and serial number, or photos, for a quote.
Yes. Airflex was an Eaton brand for decades. Danfoss acquired Eaton's hydraulics business in 2021, and Airflex is now part of Vickers by Danfoss, alongside Vickers hydraulics. It is the same product line, from the same engineering team, with the same part numbers, so we supply genuine parts and rebuilds whether your unit says Eaton, Danfoss or Vickers.
