Axial movement of the conveyor belt influence: My belt conveyor manufacturing technology becomes more advanced polyethylene roller factory, but is still a need to focus on the axis traverse study the subject polyethylene roller manufacturer because our tape manufacturing technology, belt conveyor installation technology and the world's advanced countries still have a large gap polyethylene roller supplier, often have situations belt run polyethylene roller, if care large rolls of axial movement, will cause damage earlier idlers. General axial runout better control within 0.5-0.7 mm. Roller Type Standard: roller in steel and plastic material is divided into two roller. Bearing roller has three iron and steel stamping, and Bakelite like. Roller accounted for a total cost of 35% of the belt conveyor, resulting in a more than 70% of the resistance, so the quality of the roller is particularly important.
