Impact on the conveyor belt, conveyor roller use performance reasons is the internal structure of the roller

First, the bearing bracket coaxiality difference:

The bearing seat used for the idler is the stamping part. The joint with the tube skin is not processed and the bearing seat is welded directly on the tube skin.

Second, the sealing effect is not good:

The waterproof effect is poor, and the production condition of the downhole belt conveyor is large dust, together with water dedusting, so the seal used by the idler must have good dustproof and waterproof effect. If the water in the roller will corrode the bearing, the dust will damage the bearing and the end will affect the service life of the roller.

Third, the roller axis coaxiality difference:

Because cold-drawn optical axes are produced due to the wear of the tires and other factors, the dimensional accuracy is not stable. There are often over-characteristic appearances, and it is easy to form twists and turns in the transport process, so that the coaxiality of the roller shaft is poor, and the roller shaft two-head device The bearing clearance is not ensured, and then the roller rotation resistance increases, affecting the life of the chip machine.
