While the simplest conveyor roller may be just a wheel or a set of wheels, there is no limitation on the specifications and improvements conveyor roller design can achieve. The following are some of the more specialized conveyor roller designs that have been made available in the market today.
- Impact Molded Conveyor Roller. This conveyor roller design has either rubberized or silicon coverings on the roller. These moldings absorb the force of falling materials and/or objects on the conveyor roller. Often, the moldings are non-abrasive in composition and have fixed ring stoppers at the ends of the conveyor roller. Another benefit of these kinds of conveyor rollers is its ability to reduce wear and tear while at the same time provide greater belt surface.
- Non-Grip Conveyor Roller. When the objects and/or products being transported have a sticky or gripping surface, the tendency is for these products to cling together. This can lead to products centralized on one area of the belt, causing the weight to twist the belt and misalign it. To prevent this from occurring, slick rubber disc rolls are placed on the conveyor roller. The rubber disc rolls also provide greater support to the conveyor belt edges.
- Molded Rubber Spiraled Conveyor Roller. This specialized conveyor roller has rubber spirals that keep the belt centered and balanced. The effect would be an Archimedean screw that assists in cleaning the conveyor belt and carries the unneeded material to the side of the conveyor.
- Molded Steel Spiraled Conveyor Roller. This type of conveyor roller does the same work as its rubber spiraled counterpart, except that this conveyor roller can handle heavy duty work as well as far greater loads.
