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


  1. "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.
  2. "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 direction only.

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.


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

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.
