QDG3.5-A2158 factory direct air caliper disc brake for cold header

QDG air engaged caliper disc brake is flange mounted friction type brake. It can produce high torque with different size of friction disk diameter. Normally, this brake is in releasing, after supplying air pressure, two friction linings clamp together, brake is locked, it is used for braking disk stopping.

There are two models of it: QDG3-A2155, QDG3.5-A2158. They can produce high braking force after inputting air source. These two models of brake QDG3-A2155, QDG3.5-A2158 equiped with 3# and 3.5# cylinder head in separately.

Following is the detail technical data of this type brake:
