Weather Fastness Plastic Carrying Idler Roller with Labyrinth Seal Applied in Cement Industry

Troughing Carrying Idlers are used for conveying bulk materials. Usually three rollers in one group are installed on one set. They are designed and manufactured with troughing angles of 20°,35°,45°.


Diameter:φ89-φ159mm; Tube width: 190-1800 mm.

Specification of Belt Conveyor

Carrying Roller

(Equal Troughing Idler)(mm)

Return Roller(mm)
We also make customized impact rollers and other sizes plastic rollers as your requests.

Technical Parameter

● Outside diameter run out of roller: 0.5-0.7 mm
● Revolving resistance of roller: 3.3-3.5 N
● The axial movement distance of the roller between the frame is less than 3 mm
● Applied in temperature: ≤ 80℃

Problems Analysis

Fig.1 Fig.2 Fig.3

► Fig.1The centering of the conveyor belt as it passes over the tail pulley and the centering of the load on the conveyor belt as it passes under the loading point, are the two most important factors in assuring a straight running conveyor belt.

► Fig.2 This example shows conveyor belt running centered on the conveyor troughing idlers, but the loading chute is off center to the right of the conveyor belt. The result is the conveyor belt will start moving to the left.

► Fig.3 This example shows the conveyor belt finally tracking off to the left side of the conveyor, spilling material the entire length of the conveyor.

The correction would be to relocate the chute to the center of the conveyor belt or baffle and divert the flow to the center.


► Dust-proof:"Integral labyrinth seal"design

a: Without other gaskets,the gap is small enough to keep dust outside.

b: Double sealed dust-proof bearing,and before assemble the bearing we add Lithium grease lubricant to protect it.

► Waterproof: Dust covers on both sides are out off the tube, so they can make the water outside.

► Corrosion-resistant: Outside materials of roller are plastics,the characteristics of plastics make rollers resistant to acid,alkaline,and organic solvent.

► No adhesion :Materials of roller pipe are Self-lubricating and low water absorption ,so the rollers are difficult to stick concrete etc.
