Product Feature

  The roller is an important part of belt conveyor. It has many kinds and large quantity, and can support the weight of conveyor belt and material. It accounts for 35% of the total cost of a belt conveyor and produces more than 70% resistance. Therefore, the quality of idlers is particularly important. They are made of steel and plastic.

  The roller is to support the conveyor belt and material weight. The operation of idler must be flexible and reliable. Reducing the friction between conveyor belt and idler plays a key role in the service life of conveyor belt which accounts for more than 25% of the total cost of conveyor. Although the idler is a small part of belt conveyor and its structure is not complicated, it is not easy to produce high quality idlers. The criteria for judging the quality of idlers are as follows: radial runout of idlers; flexibility of idlers; and axial runout.
