Idler rollers can be manufactured to suit almost any conveyor application. Some variables include bearing brand, bearing size, diameter or series, wall thickness, seal type and material type. Different variables can be selected and customised to suit your application's standards and specifications.
Different idler rollers are used for various processes, and some determining factors could be material type, specific gravity of the material and lump size.
Plain rollers are the most common type of idler roller. They are used to support and shape the conveyor belt.
Plain rollers can be fitted to the load side of the belt in trough, tracking and transition frames. Additionally, they can be fitted to the return side of the belt.
Tapered idler roller can be installed on both the load or return side of the belt. They assist with conveyor belt tracking when they are installed in a tracking frame.
The name for the rubber-coated idler roller is derived from the rubber that is vulcanised directly to the roller. Rubber-coated idler rollers are tear, impact and friction-resistant and therefore have a higher durability than non-coated idler rollers.
A rubber disk idler roller has durable rubber discs positioned at regular intervals along the roller. On the two ends of the roller, the rubber discs are bundled together to provide more support for the conveyor belt edge.
The spaced-out positioning of the rubber disks is to separate any carryback (leftover materials adhered to the belt after a scraper has performed its cleaning function). This helps to reduce material build-up on the outside of the roller, a common cause of belt mistracking.
Rubber screw idler rollers incorporate an anti-tear rubber coating in a continuous screw pattern along the roller. The screw pattern assists with the removal of material build-up on the belt and helps maintain belt-tracking.
Similar to the rubber screw idler rollers, the steel screw idler rollers have the same continuous screw-patterned coating along the roller. However, its component is steel instead of rubber.
The screw pattern assists with the removal of material build-up on the belt and helps maintain belt-tracking.
Steel screws have a greater scrubbing action than rubber screws, and thus steel screw idler rollers are more effective where carryback is heavy.
An example of where a steel screw idler may be effective is an application where scrapers cannot be used to clean the belt, such as a mobile plant conveyor. At a mobile plant conveyor, fitting a scraper is not possible due to insufficient room. Another example is in a folding conveyor, which may prohibit the fitting of such devices.
