Conveyor rollers are used in unpowered (gravity-flow) roller conveyors, powered roller conveyors, roller-bed belt conveyors, and material transport stands to support and move bulky items such as boxes and totes. These replacement rollers can be used to replace or upgrade the existing rollers on compatible conveyors or stands. Each roller has a spring-retained axle that can be pushed in to install or remove the roller from the conveyor frame or stand. The rollers let loads roll from one place to another, reducing the effort it takes to move the loads in warehousing, package handling, manufacturing, and distribution tasks. Loads roll forward and back on the rollers, and they can be pushed from side to side along the width of the conveyor.
The basic types of rollers:
(1) The rollers are classified into self-aligning rollers, buffer rollers, trough rollers, and parallel rollers according to their uses. The function of the self-aligning roller is to correct the deviation of the belt of the belt conveyor. Usually, a rotary groove-shaped self-aligning roller is installed on the heavy-duty section of the conveyor, and a parallel self-aligning roller is installed on the no-load section. The buffer roller is applied to the tailstock of the machine according to the actual situation. When receiving the material, it can reduce the impact of the material on the belt, which is beneficial to the service life of the long belt. The trough-shaped roller is generally composed of two side rollers and a flat roller. The groove angle is generally 30 degrees. For a detachable belt conveyor, the three rollers of the trough-shaped roller are hinged to each other, so Called hinged roller. The parallel roller is generally a long roller, which is installed at the lower end under pressure, so it is called the lower roller.
(2) The rollers are divided into two types: steel rollers and plastic rollers. There are three types of bearing seats for rollers: cast iron, stamped steel plate and phenolic plastic.

What should be mastered when customizing rollers?
(1) Determine the style and type of rollers. Due to the different performance of different rollers, the scope of application is also different. Before customizing, determine the best style and type according to the specific usage. Usually, the staff of custom manufacturers will recommend several different types of rollers, and try to choose the one with new style, good performance and stable quality.
(2) Understand the customized price of rollers. Different rollers have different prices. Before customizing, you can understand the market price situation. Under the premise of determining the quality, try to choose the one with the lowest quotation.
