China factory Q235 good quality conveyor carrying roller

Material of Conveyor Idler Roller

1) Pipe

*Carbon steel, stainless steel, galvanization 

*Surface of steel tube should be smooth

*Without any fault such as crack, folding, layering or lap welding  

*Ovality shoud be less than 1/2 of tolerance of outer diameter

*Curvature should be less than 1.0mm/m

2) Bearing

*Rollers adopt C3 deep groove radial ball bearing which adopts bidirectional 

 seal structure to improve the performance of water-proof and dust-proofing.

3) Seal

Noncontact seal: It is seal and its relative motion parts don't contact, and there is proper clearance seal.

Advantage 

*Almost do not produce friction heat in the work

*No wear and tear, especially suitable for high speed and high temperature occasion.

*Forming a complex, winding and narrow maze between inner and outer seal  part.

*The good performance of water-proof and dust-proof.

4)Lubrication

Rolling bearing lubrication purpose is to reduce the bearing internal friction and wear, prevent burning stick.

The lubrication effect is as follows.

*Reduce the friction and wear

*To extend the fatigue life  

*Discharge the friction heat and cooling

*To prevent foreign matter into the bearing internal, or to prevent rust and 

 corrosion etc.
