return spiral rubber roller

Roller is an important part of COEYOR IDLER whether the belt conveyor can work properly is closely related to the quality of roller.

The indicators to measure the quality of idlers are as follows:

1. Roller radial run-out quantity (this index directly affects the stability of material transportation.)

2. Axial string momentum (directly affects the service life of rollers)

3. Flexibility ratio  (directly affects the service life of rollers & belt)

4. Waterproof ness（directly affects the service life of rollers）

5. Dustproof ness（directly affects the service life of rollers）

6. Axial loading capacity（directly affects the service life of rollers）

7. Shock resistance（directly affects the service life of rollers）

8. Rotational resistance（directly affects the service life of belt）
