DPA
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.
- 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
