Product Information


Material of EX300 carrier roller

EX300 carrier roller materials are generally 50Mn, 40Mn2, etc. The main process is casting or forging, machining, and then heat treatment. The hardness of the surface of the wheel after quenching must reach HRC45 ~ 52 to increase the wear resistance of the surface of the wheel. The processing precision of roller axles is relatively high. Generally, CNC machine tools are required to meet the requirements. The material is mostly 40Mn2. After processing, quenching heat treatment is also required, and the hardness reaches about HRC42.

The role of EX300 carrier roller

EX300 carrier roller's main role is to maintain the linear movement of the

chain rail. If a fault occurs here, the track chain can't keep the linear. EX300

carrier roller is a lubricating oil injected at one time. If an oil leak occurs,

we can only replace it with a new one. In the work, try to avoid the rollers

from being immersed in water for a long time. In general, we must keep the

platform clean and free of dirt and debris. More hinder the rotation of the sprocket.
