Pneumatic Disc Brake
Principle: NAB brakes, mounted on tapered bushing with wedges, have friction plates that can be exchanged while maintaining the mechanical equipment as is. Heat generated by friction is dissipated by cooling blades mounted on the hub's disk. The friction plate is double-cut, through the hole...
Heat generated by friction is dissipated by cooling blades mounted on the hub's disk.
The friction plate is double-cut, through the hole with hub disc, screw driver to remove the countersunk screw can exchange friction plate.
Features of Industrial Brakes NAB Air Through Shaft Disc Brakes
Stop peacefully and simply
It can stop without hinder according to air pressure adjustment.
Mostly suitable to quite frequent sliding movement
It can be used in high frequency, high load, and sliding movement.
Wide adjustable range of torque
It can adjust torque in wide range according to air pressure adjustment.
Long life for friction plate and easy to replace
It gets longer life due to thickness of friction plate. And when replace,it works without changing anything of the mechanical equipment.

Advantages:
1,Effective
exothermic, "continuous sliding" exothermic effect is good, by using
heat capacity is very big with a heat sink disc, so compared with the
electromagnetic, heat capacity, high frequency, stability of continuous
sliding using torque due to not use is tasted, so not going to happen
and make the product degradation due to overheating, even if the
temperature rise will not reduce the torque.
2,A
wide range of torque control, by changing the air pressure to make the
mechanical subtle torque adjustment is possible to prevent overload
gate, tension control, soft start smooth stop and so on are implemented
with good accuracy.
3,Pneumatic
safety, no electrical spark, because do not use electrical, so no
electrical spark, safe and reliable. Non-asbestos friction plate
friction side does not use asbestos, achieve good wear resistance and
heat resistance.
4,Slow
and free, high speed actuation and electromagnetic than 20 percent
faster response speed, smooth connection and braking torque transmission
adjustment is very simple, smooth dynamic connection, braking. The
smooth actuation makes the mechanical durability upward and produces
great value.
5,Long
life, maintenance simple heat release effect is good, the thickness of
the friction board has a lot of margin, and electromagnetic type
compared, the life is 2.5 times to 5 times longer. Simple installation
and operation due to its simple structure and integrated structure, so
the installation and operation are simple, friction plate exchange is
simple, is designed to be easy to exchange friction plate type.
