Ceramic idler pulley is a composite component composed of ceramic body, bearing, shaft, and plastic labyrinth seal ring. It is a new breakthrough in the application of ceramic instead of steel and plastic, which is made by high-temperature calcination. It is a new type of product for roller replacement, composed of ceramic body, bearing, shaft, and plastic labyrinth seal ring.
1. Corrosion resistance: Neither acid nor alkali salts have a corrosive effect on it.
2. Strong hardness: Strong wear resistance.
3. Fully sealed: Both ends are equipped with plastic labyrinth seals, which prevent oil and grease from leaking and allow the rolling shaft to operate in a fully sealed state for a long time.
4. The ceramic surface forms an oxide film, which does not adhere to any substance and does not react with any substance. The groove type roller is used to remove belt stains. On a sloping belt, there is high force and low resistance, resulting in excellent performance. Double section idlers can reduce the heavy pressure points of the belt on the idlers. The hollow device of the idlers can allow the belt to fall off on its own without sticking to the idlers, which can extend the service life of the idlers.
5. Long service life, 2-3 times longer than steel rollers, and can reduce belt wear, extending belt service life without running.
6. High economic benefits can reduce the overall cost of belt conveyors and decrease maintenance hours.
