2. Nylon grounding roller ,nylon plastic 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 |
