NAB0.2 Updated mini size air shaft brake for precision machine

NAB0.2 is an update mini and compact air shaft brake, it is used for light torque, small size precision machine for rotating part braking. This NAB air shaft brake is design and made by Handong company, it can alternative NIIKA NAB pneumatic brake, HAC HDB air brake, ASAHI BSB shaft mounted brake with superior quality and competitive price. 

NAB model pneumatic brake is industrial friction type brake. It can be used as a brake and tension controller. When used as a tension controller, its braking force is less than used as a brake's braking force, adjusting air pressure less than 0.6Mpa.

This mini NAB brake NAB0.2 is also composed of cylinder, piston, aircraft, friction plate, return springs and others. Its working mode is the same with other NAB brake, brake relies on air pressure for braking, return springs to release. After supplying air pressure, piston pushes piston aircraft and friction plate pad move towards 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 screw driver to take out head inside screw through hole of disc with hub, in order to replace friction linings.

Use air pressure as power source, it is safe and economic. There are some models of it: NAB-5, NAB-10(T), NAB-20(T), NAB-40(T), NAB-65(T), braking torque is 53N.m to 636N.m when air pressure is 0.6Mpa. Following is the technical data of this brake for your reference:
