Belt conveyor idler is an important component of many kinds and large quantities. It accounts for a total cost of 35% of the belt conveyor idlers
Bear more than 70% of the resistance, so the quality of the roller is particularly important.
Role is to support the roller conveyor and material weight. Roller operation must be flexible and reliable. Reducing roller conveyor with friction, accounting for the total cost of the conveyor belt more than 25% of life plays a key role. Although the roller is a relatively small component in the belt conveyor, the structure is not complicated, but produce high-quality roller is not easy.
Analyzing roller quality standards were the following: roller radial runout; axial runout; roller flexibility.
