Energy Saving Troughing Carrying Idler Roller with Diameter 133 mm
on tube Applied in Steel Industry
We can manufacture the rollers of diameter 89-219mm length
190-3400mm, which are used in the steel industry, harbor, coal
industry, power industry, cement industry, etc. and we have Passed
CE certification and ISO9001: 2000 certificate.
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°.
Training Problem Conveyors
Fig.1 Fig.2 Fig.3
- "Straight" (over 90°) This stand has no tilt, and is designed for
the conveyor belts to run in both directions. It has no real assist
in belt tracking.
- "Tilted" (2°) In the direction of belt travel. Conveyor belts are
to run in this direction only. The 2° tilt offers good results in
conveyor belt tracking.
Straight stands can be tilted 2° forward by placing a 1/8" thick
washer under the back side of idler stand indicated by arrows.
Remember, this conveyor only runs in one direction.
Many times on reversing conveyors, the belt runs great in one
direction, only to run off when reversed. Question? What are you
using? If you are using tilted stands, they are good for one
On reversing conveyors where tilted stands are already in service
and giving problems, you can neutralize the tilt by placing a 1/8"
thick washer under the front side of the idler stand opposite the
side indicated by arrows. Now with the tilted stands neutralized,
you can run your conveyor belt either direction.
The only part of the troughing idler that has any training effect
on the conveyor belt is the center roll indicated by the arrow. Re-read this statement.

What Makes Hongda Rollers Top Quality
Unique design of roller body, two sealed covers in ends are out of
tube, which effectively prevents water in.
labyrinthine dust-proof design sets layers of defence, which
prevents the dust from entering the heart of roller -- bearing.
More components of the roller are treated by special technique,
less maintenance is needed during working processing.
After analysis of mechanical properties and physical properties of
various plastics, and after practice and test, Hongda finally
chooses NYLON, PP(Polypropylene), HMWPE (High Molecular Weight
Polyethylene) as the main material to produce the parts of roller
by modification or single way. The parts' work are aligned well in
variety of environments.
Craftsman's spirit, making every detail perfect from material
selection to processing.
Customize plastic(nylon) roller fitting in various adverse
circumstances according to customer's requirement.
