Track Roller

Track roller round body material generally 45 steel, 40 Mn2, and other materials, main process casting or forging, mechanical processing, then heat treatment, surface hardness of hardened wheels to HRC38 or so, to increase the surface of the wheel wear resistance. Track rollers process accuracy are higher, the general is the need to carry on the processing can achieve numerical control machine tool requirements. Materials to 40 Mn2 more, after processing were also quenching heat treatment, hardness of HRC42. Or so.
