Eaton Airflex Expanding Clutches & Brakes - ER

Eaton Airlfex expanding clutches and brakes maximize performance in braking and tensioning applications. The drum style products expand radially outward when pressure is applied, forcing friction shoes against an inner cylindrical drum surface to create stopping torque.

Flexible ER expanding couplings create electrical isolation between connecting shafts. Perfect 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where a disconnect is required without stopping the prime mover, or in which the driving equipment must be frequently withdrawn from the drive.

Typical applications include centrifuges, core expanders, laundry machines, textile machines, and tire building machines.

Standard Sizes: 

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