Sprockets And Segments For Excavators & Bulldozers

Short Description:

According to the size of the model and the usability of the industry and mine, the sprocket can be made of materials: 35MnSi, 35Mn2,40Mn etc. After the normalizing heat treatment of the sprocket blank, the matrix hardness reaches above HB235, and the driving tooth is hardened by medium frequency induction hardening and tempering at low temperature. The surface hardness reaches HRC48-54, and the hardening depth is above 5-10mm (HRC45). It can accurately transmit power under harsh working conditions, and has excellent anti-wear performance, which significantly improves product life and reduces customer use costs.

Product Detail

Product Tags


1. The sproket and segments we produced are used  for a very complete range of machines, from 0.8 to 100 tons excavator and bulldozer.
2. The parts are suitable for both excavators and bulldozers.
3. The sprockets are molded or forged and subsequently processed, giving them a special heat treatment to make sure well hardness.
4. Use precision processing technology and special heat treatment technique to reach best wear-resistance and have maximum extent loading capacity as well as anti-cracking ability.

Difference between sproket and segment:

Sprockets are metal cogwheels that consist of a metal inner ring with bolt holes or a compression hub and a gear ring in one unit. Sprockets can be screwed on directly, or pressed onto the machine’s drive hub, and they are usually used for excavators.
Just like sprockets, segments also consist of a metal inner ring with bolt holes and a gear ring. Unlike sprockets, segment groups exist from individual segments which make up the sprocket for the undercarriage of bulldozers. This means that the segments can be exchanged without dismantling the track link.

How to confirm the size of the sproket:

For normal excavator or bullzer, the sproket and bulldozer size are standard. We can choose the sproket according to the excavator and bulldozer brand and model. If the excavator and bulldozer are unusual models or need to be cusomized, we need the following size information in the drawing to make sure we will offer right sproket.


The sproket and segment can be used as the after selling service parts for most of the famous excavator and bulldozer  brand  such as KOMATSU, CATERPILLAR, HITACHI, KOBELCO, SUMITOMO, KATO, HYUNDAI, DAEWOO, DOOSAN, JCB, SHANTUI etc.
