Kobelco CK2000-2 Sprocket also is called casting Kobelco CK2000-2 driving Sprockets or 

Kobelco CK2000-2 sprocket wheel, it is made of 40Mn2, under casting and heat treatment. 

Its warranty time is 2000 working hours.

Our sprocket wheel uses good hardenability steel, so that the crawler crane could reduce the

wear of driving tumbler, 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.

This products is called sprocket in crawler crane and excavator, and segment in bulldozer.

The sprocket is connecting with diving motor, transmit power to the track directly, so as to drive

the chassis parts.

The products mainly have these processing methods: casting, machining, heat treatment such

as tempering, quenching, medium frequency quenching, harden.

It also is called: sprocket , crane sprocket , crawler crane sprocket , driving sprockets , sprocket

wheel , sprocket-wheel , wheel drive , driving roller , driving wheel , tumbler drive , undercarriage

parts , crawler crane parts and so on.
