Material of conveyor idler carry 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 of Red Flag Conveyor Idler Roller

1)Good roller radial runout  

2)The axial string momentum is good 

3)Good Flexible

4)Good waterproof performance  

5)Good dustproof performance 

6)Good Axial bearing capacity  

7)Good Impact resistant ability  

8)The rotation of the smallest resistance  

9)Low noise,Cleaning well. 

10)Life time: More than 30000 hours

Conveyor roller can use for coal,mining,steel plant,electric powder plant,chemical industry,building material plants,salt field plants,sea ports and so on

Standard plastic package, wooden package box or as require

Our company received the certification of ISO9001-2008. The non-metallic macromolecule composite material carrying idler is a breakthrough of our company, which won the “Outstanding Invention Award”. 

Our Composite roller use life is 3 years.If the roller is broken within 3 years,we will change a new production
