conveyor steel trough roller replacement
Our Conveyor roller’s structure is of high seal, water proof and dust proof, its bearing assembly is
high accuracy bearing chamber and high quality bearing. Our conveyor roller is reasonable in structure, low in noise, free for maintenance and long life time
(over 50,000 hours), it could be the best choice for belt conveyor system. We also innovate Controllable Brake roller for downward belt conveyor, which could solve the brake along the belt conveyor.
