Product Description
High quality Single axis magnetic powder brake Factory price
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 with hub disc, screw driver to remove the countersunk screw can exchange friction plate.

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.
