PBT Hollow Shaft Powder Particle Brake 
 

Powder Particle Brake Notes 
1. Don’t overload, meanwhile cool to appropriate temperature 
The value of the torque/rotational speed/slip power should be less than the rated value. The cooling mode(natural cooling/forced air cooling/water cooling) should depend on the maximum slip power when it works and the cooling air should pass the water and oil filter. The temperature detector and the alarm should be installed to prevent high temperature which can affect the service life of the magnetic powder.(the highest temperature is 80 degree). 

2. Concerning the service life 
The life of the magnetic powder clutch and brake rely on the life of the magnetic powder. Generally speaking, its service life is 4500-7500 hours in the state of non-overloaded; but its service life can extend several times in some cases, such as: the working torque of the magnetic powder clutch/brake, relative slip rotational speed and slip power can be reduced to 50%-70% of the rated value. This is to say, the margin can be enlarged as soon as possible when designing.
