motorized gravity pulley 

Certification:ISO, MA,TUV

Type conveyor: DTII, TD75 

Material: carbon steel, Rubber , nylon etc. 

The international Market:  Middle east, South America, Africa,

Southeast Asia. Etc.

Feature of motorized gravity pulley

1. Steady running, reliable quality and reduce maintenance;

2. Less movement longitudinally, rotating smoothly, extends the life span;

3. Various bearing housing and sealing structure are available for the customers choice;

4. Multipass labyrinthine sealing,preventing the mixed dirt and water immersed; 

5. Manufacturing by steel pipe specially for of high precision roller, ensuring the strong load, 

    low shaking and less noise. 

Components of motorized gravity pulley

1.High quality raw material: Q235 / Q 245 / Mn steel plate.

2.Bearing: LYC, HRB, NTN, etc.

3.Long service life (about 8 years).

4.It can work in the dusty, wet, muddy or other harsh environments.

5.Welding: Mixed gas TIG.

6.Painting: ordinary painting, hot-dip galvanzing, electrostatic spray, baking varnish

7.Lubrication: Lithium grease, rust Inhibitor.

Testing measures

We have strict quality testing and performance testing to ensure the quality of our belt 

conveyor roller.

Testing standard

1.End travel<0.5

2.Axial application of force(15KN) cudgel and axle don’t come away

3.1M free flat slump: Weld joint without harm

                                        Axial displacement ≤1.5

4.180/KG(cm) free vertical slump:Weld joint without harm

                                                               Axial displacement ≤1.5

HuaYun conveyor roller and pulley are widely used in mines, caves, 

cement works, coal-fired electric utilities and dock installations.
