Hengyang Heavy Industry Pneumatic Caliper Disk Brake CQP12.7-A Asbestos Free Automatic Gasket

5、 The air bag piston rod undergoes multiple processes of processing, wear-resistant plating and polishing treatment, with a beautiful appearance and no wear on the "v" type seal. Strict tolerance fit and concentric requirements are required for the front cover, shaft sleeve, piston rod, piston disc, etc. The clearance between the piston rod and shaft sleeve is 0.02-0.03mm on one side, allowing the entire piston to move flexibly and effectively ensuring the working thrust of the air bag.

6、 Strict quality monitoring of springs and reliability testing of each batch ensure that the springs will not experience fatigue damage, fracture, etc. under normal working conditions, effectively ensuring the braking thrust of the air bag and completely preventing major malignant accidents such as brake failure

The QP series pneumatic device is mainly used for the power unit of the QP caliper disc brake. High quality shell

Quality aluminum alloy die-casting casting, with special process treatment, has high mechanical strength and resistance to corrosion

Grinding performance. Lightweight, all seals used are directly imported from Italy, and the entire machine has undergone 300000 RMB

More than one life test, and intact. Excellent working performance, fully meeting various requirements

The braking work of pneumatic caliper disc braking under certain conditions can directly replace imported ones.
