NAB pneumatic shaft caliper disc brake unwinder

NAB pneumatic shaft caliper disc brake is normal release, it is controlled by air pressure. When supplying air source, then this NAB brake brake, after exhausting air source, this NAB is released, then connected shaft and relevant part working again.

NAB pneumatic shaft caliper disc brake working thoery is like this:

NAB model brake relies on air pressure to brake, return springs to release. After supplying air pressure, piston pushes piston aircraft and friction plate move towards to and compressed shaft attached lining disc, disc and other rotating parts stopped, brake braked. After exhausting air pressure, piston aircraft and friction plate are separated with shaft attached lining disc by return springs, brake released.

It reduced heat generated from friction by cooling plate mounted on disc with hub. Friction plate is two-cut style, using screwdriver to take out head inside screw through hole of disc with hub, in order to replace friction plate.

There are some models of this NAB pneumatic shaft caliper disc brake, including NAB-2, NAB-5, NAB-10, NAB-20, NAB-40, NAB-65. Following is the technical data of this NAB pneumatic shaft caliper disc brake for your reference:

NAB model air brake is standard shaft brake, it is normally releasing. Torque adjustment range is wide, easy installation, good heat dissipation, long service life. This brake is widely used in food machinery, printing machinery, packaging machinery, tire machinery and other machinery.

In this case, NAB pneumatic shaft caliper disc brake is worked with flange mounted safety chuck in turntable working place for steel bar stop.
