Caterpillar Bulldozer Carrier Roller D8K/D8H
Features of Carrier Roller
1).Unique Technology
The unique technologies applied to the production of our bulldozer undercarriage parts include forging, quenching and tempering. In addition, the threaded part of our carrier roller receives a medium and medium frequency treatment so its rigidity is over 2 times that of other similar machinery parts with regular threaded joints.
2). First-Rate Material
These excavator undercarriage parts are made from 40Mn or 50Mn.
3). Superior Manufacturing Techniques
Our advanced forging techniques are used to produce the roller body, front cover and rear cover of our carrier rollers.
4).Excellent Sealing Property
All of our carrier rollers go through the 0.6-0.8MPa water pressure and passes the air tightness testing for excellent sealing.
5). According to Your Standard
The undercarriage part’s machining and tolerance of fit are designed according to Chinese standards, though we adjust and install the undercarriage parts according to your country’s standards.
