2. Belt conveyor roller Inner structure and material

Tube	tube special for roller,compared with ordinary steel tube, in the following aspects,it has great advantages which can make the roller have minimum radial play eccentricity
Shaft	high precision cold-drawn steel which has high brightness and little tolerance.
Shaft end	both ends of the tube are simultaneously machined and chamfered.
Bearing	use deep groove ball bearing with big clearance, it’s C3, C4. And this clearance can make rollersrevolve flexibly. Bearing type is 2RZ and 2RS with oil seal which have advantage in dust proof.
Lubrication	Grease is Lithium soap type grease with Rust Inhibitors
Seals	multiple labyrinth seal,the material we can provide has ABS resin, Nylon, Hdpe,Polyurethane, polyformaldehyde and so on.
Welding	mixed gas shielded arc welding end.
radial eccentricity	We can assure play radial eccentricity less than 0.5, if have special requirements, it can reach 0.2~0.3.
Rubber	it can be changed separately, so it can reduce the cost for you. Rubber cold resistant -45 degree Celsius and high temperature resistance 120 degree Celsius. The rubber hardness 65-70 SHORE.
Drawing	We have professional engineer to design the type of roller. Also we can produce according to your drawing and request.
Painting	ordinary painting, hot galvanized painting, electric static spraying painting, baked painting
