Track Roller is Crawler Crane undercarriage parts, also is called Lower Roller, Bottom Roller, or Return Roller. It is made of 40Mn2 or 50Mn, under casting and heat treatment.
Our Track Roller uses good hardenability steel, so that the crawler crane could reduce the wear of the track roller, that is important to ensure high-quality work and high efficiency, and has good impact toughness, a certain depth of quench layer and transition layer to improve the bearing capacity, wear resistance and resistance to contact fatigue. Through whole quenching & high temperature tempering, then the integral key surface quenching.
We take advanced equipment and technology, and carry out strict tests to ensure the quality, such as chemical composition, hardness, impact toughness, precision, function, and so on.
The products mainly have these processing methods: casting or forging, machining, heat treatment such as tempering, quenching, medium frequency quenching, harden.
