ASTM Standard 30m/Min Heavy Duty Metal Rollers Impact Resistant
Heavy-Duty Polyethylene Molecular Roller with Belt Conveyor
The roller is the main set of parts of the belt conveyor, which is used to support the belt and heavy objects to ensure that the conveyor belt conveys materials smoothly along the direction of the belt. At present, the existing rollers are generally made of steel, ceramics, polymer, rubber, electric powder, and other materials. When the load is heavy, the surface of the roller cylinder is worn out, and the service life of the bearing is also greatly shortened, which in turn affects the performance of the roller. Service life.
1) Solid design, suitable for heavy lifting.
2) The bearing housing and steel tube are assembled and welded with
a concentric automatic.
3) Cutting of the steel tube and bearing is performed with the use
of a digital auto device/machine/equipment..
4) The bearing end is constructed to ensure that the roller shaft
and bearing can be firmly connected.
5) Fabrication of the roller is effected by an auto device and 100%
tested for its concentricity.
6) Roller and supporting components/materials are manufactured to
DIN/ AFNOR/ FEM/ ASTM/ CEMA standard.
7) The casing is manufactured with highly composite, anti corrosive
alloy.
8) The roller is lubricated and free from maintenance.
9) Woring life expectancy is up to 30,000 hours or more, depending
on usage.

Application Scope:
Flate/Carrier/Carrying Rollers: Used to handle bulk&unit material.
Impact Rollers: Installed at the loading point to absorb the shocks and to help protect against belt damage.
Return Rollers:used to sustain and support the belt during its return section and performs a cleaning action.
Return rollers with spaced rings(comb rollers/rubber disc roller)
Return roller with helical rubber rings(spiral rollers)
Self-aligning/Training Rollers:
Used to adjust the belt deviation preventing hunting and ensuring stable operation of conveyor belt.
