Roller is an important part of belt conveyor, the quality will directly influence the service life of the adhesive tape machine. We should pay attention to the importance of supporting roller structure, here to introduce roller design and selection of sealing ring structure.

Roller sealing performance is good or bad, have a great influence on the service life of the roller. The seal is to prevent external dust, coal dust, moisture into the bearing. Press the sealing principle can be divided into contact and non-contact seal seal. The contact type seal for rotary speed is not too high, non contacting mechanical seal for rotary high speed situations. Roller seal generally adopts the contact type seal, that is, the labyrinth seal, the best axial labyrinth seal effect, resistance is small. Some use a radial maze, also some roller using two sets, the effect is better, but more complicated.
