Industrial Clutch Parts Ltd. supply a complete range of Eaton Airflex Expanding Clutches & Brakes. The drum style products expand radially outward when pressure is applied, forcing friction shoes against an inner cylindrical drum surface.

Eaton Airflex ER units have been engineered as shaft couplings or holding brakes where engagement occurs at zero speed differential between the element and drum. ER elements engage their drums directly with the outside rubber surface of their actuating tubes.

Type ER Characteristics:

  • Torque Range: 440 - 3,550 lb-in
  • Max. Speed: 1,800 rpm
  • Max. Pressure: 110 psi

Eaton Airflex Expanding Clutches & Brakes Type ER

Industrial Clutch Parts Ltd. is an authorized UK Distributor for Eaton Airflex Clutches & Brakes. Our large stock of Eaton Airflex products ensures prompt delivery and reduced lead times for our customers.

Eaton's Expanding Clutches & Brakes maximize performance in braking and tensioning applications. The ER Type units come in a range of sizes with a rugged, tire-like neoprene and cord tube that expands radially, forcing a friction surface against an inner drum to create stopping torque.

Type ER Expanding Clutches & Brakes provide a large torque in a relatively small package. It also creates electrical isolation between connecting shafts. ER elements are used as shaft couplings or holding brakes where engagement occurs at zero speed differential between element and drum. Ideal for applications where a disconnect is required without stopping the prime mover, or in which the driving equipment must be frequently withdrawn from the drive.

ER elements are best suited in applications such as Centrifuges, Core Expanders, Laundry Machines, Textile Machines, and Tire Building Machines.


  • Expanding units with neoprene facing.
  • Engagement of the element should occur when there is no speed differential between driving and the driven shaft.
  • Available in ten sizes; the smallest expanding to a 3" (51mm) diameter drum, and the largest to a 24" (610mm) diameter drum. 

Standard Sizes: 

  • 3ER125, 6ER200, 8ER250, 10ER300, 12ER350, 14ER400, 16ER475, 19ER475, 21.5ER475, 24ER475
