As one of the most common parts of conveyors, idlers are often used in all kinds of conveyors. Here we need to understand the roller as a conveyor accessories several major characteristics.
1, roller wear resistance, long service life. The roller body special polymer material, has the very good wearability, moreover has the good self-lubrication performance, the surface is smooth, does not injure the conveyer belt, the net belt and so on main parts.
2, the roller internal structure is reasonable, reliable seal. Roller is equipped with two seals, high manufacturing accuracy, the gap is coated with special grease, can effectively prevent dust, gas, liquid and other corrosive media into the roller, damage the bearing, reduce the impact of external factors on the roller.
3, roller their anti-corrosion performance is superior. Roller body and seals are made of polymer materials, corrosion resistant. In corrosive service, the service life can reach 5 times of ordinary roller. The specifications of polymer corrosion-resistant roller include 4 series, including 89, 108, 133 and 159, with more than 30 varieties. We can also manufacture non-standard roller accessories according to the requirements of users. There are MC nylon and polyurethane two categories, according to the characteristics of corrosive substances used in the environment choice.
4, idlers generally light weight, small rotary inertia. Roller special polymer material weight is light, the specific gravity is one seventh of the steel, with this material made of accessories, weight is about half of the ordinary roller, small rotary inertia, the friction between the roller and the belt is small.
