Trough Idler Roller Assembling with Bracket on Belt Conveyor

The Company is equipped with advanced idler production line, the production of series idler adopts the reliable labyrinth, non-contact seal structure. The bearing (Swedish SKF, Japanese NSK, etc.) can get well lubricated and by whichfurther improve the service life of the idler. Idlerhas become the company's main export products.

Main Features
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 concentration.
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) Working life expectancy is up to 50,000 hours or more, depending on usage.
10)Vacuum sealed which has withstood anti water, salt, snuff, sandstone and dust proof experiments.
Application Fields:
•Coal mine industry: transportation for coal, gangue, stuffing, etc.
Electric power industrytransportation for coal and coal ash in power plant
•Steel industry: transportation for ore, fine ore, etc.
•Ocean engineering: transportation for material in wharf, port,etc.
•Food processing: transportation for food, raw material, food material, etc.
•Cement industry:transportation for stone, rock flour, raw material, etc.
•Chemical industry : transportation for corrosive materials
•Low scaling: good self-lubrication and adhesive resistance.
•Light weight: for the density, it is less than 1/7of the steel pipe;for the weight, it is only1/4of the steel pipe. It is easy in installation and replacement, with low labor intensity and installation costs.Performance comparisons with other materials:
