Product Description
The carrier wheel is one of the four wheels-belts of the crawler-type construction machinery chassis. Its main function is to Support the weight of the excavator and bulldozer, and let the crawler track along the wheels.
Material of carrier rollers:
The material of the sprocket wheel body is generally 50Mn, 40Mn2, etc., the main process is casting or forging,Machining, and then heat treatment, the hardness of the wheel surface after quenching should reach HRC45~52,To increase the wear resistance of the wheel surface.
Structure of carrier roller:
Wheel body, roller shaft, shaft sleeve, sealing ring, end cover and other related components. Rollers can be divided For unilateral rollers and bilateral rollers; rollers for excavators and rollers for bulldozers, excavation rollers The track rollers for excavators are generally painted black, and the track rollers for bulldozers are generally painted yellow.
