1. The design of the gap ensures lubrication of the worn surface.
2. Special steel shell not only prevents deformation but also perfectly combines with pressure.
3. A good heat treatment can ensure the depth of hardening and improve wear resistance, while a good support structure prevents deformation.
4. High surface hardness and standard process can guarantee the service life of iron/copper sleeve.

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.
