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|
(Equal Troughing Idler)(mm)
|We also make customized impact rollers and other sizes plastic
rollers as your requests.|
● 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℃

► 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
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
