The Eaton Airflex® Type 200DPA is a symmetrical opposed piston caliper brake design that is well suited for most high torque, high energy stopping applications.

Engineered for hydraulic actuation, the Airflex® 200DPA is a robust design able to withstand the tough operating conditions associated with industrial applications.

Why the Airflex® 200DPA

  • High quality
  • High performance
  • Low cost of ownership
  • Low maintenance
  • Long lining life

Features

  • A large piston area and 2000 psi operating pressure range give high frictional force resulting in more torque
  • Base or split mounting for flexibility of mounting and accommodation of different disc thicknesses or diameters to meet diverse customer requirements
  • Guide pins transmit torque from friction shoes which prevents piston seal leakage that could result from misalignment between the friction shoe and disc
  • Large friction area for long life and reduced maintenance due to friction material wear
  • Automatic friction shoe wear adjustment with each engagement
  • Solid or ventilated discs to optimize performance and lining life
