Idler rollers, or sometimes simply known as conveyor rollers, are cylindrical-shaped bars that run along and underneath a conveyor belt. There are many different types of idler rollers with varying functions.
Usually, idler rollers aid in the supporting of weight and impact of the materials being transported along the belt. They also assist in the smooth, continuous movement of the material along the belt.
Idler rollers can be self-aligning and assist in maintaining the belt tracking. Depending on the structure and shape of the conveyor belt, the rollers are usually positioned within a metal frame and are known as idler sets.

Polyester (EP) Conveyor Belt
1.Polyester conveyor belt, also called EP or PN
conveyor belt, whose tension resistant body is canvas
is woven by polyester in warp and polyamide in weft.
2.The belt has the characteristics of low elongation in
warp and good trough ability in weft, good for water
resistance and wet strength, suitable for medium,
long distance and heavy-load transportation of materials.
3.Because of high initial modulus of polyester, the belts can choose a relative low safety factor.
