Eaton-Airflex ER couplings are used in:

• Centrifuges
• Core expanders
• Laundry machines
• Textile machines
• Tyre-building machines

Airflex ER couplings are expanding units with neoprene facing. As such, they combine the advantages of a flexible and disconnected coupling. Engagement of the element should occur when there is no speed differential between the driving and driven shafts.

ER elements are used as shaft couplings or holding brakes where engagement occurs at zero speed differential between element and drum. The ER is ideal for applications in which a disconnect is required without stopping the prime mover or in which the driving and/or driven equipment must be frequently withdrawn from the drive.

Torque capacities up to 118,000 lb-in, 13,300 N-m.
