Track roller is an important parts of rotary drilling rig chassis. Its main function is to support the whole weight of rotary drilling rig machine, and make the track moves along the track roller. And at the mean time, it is also used to restrain the track and prevent it lateral slippage. 

Usually, it includes lower roller and upper roller. Lower roller is on the bottom, and upper roller is on the top. Some machines' lower roller is same with the upper roller.

2. Production process

Cutting → Forging → Rough machining → Heat treatment (quenching and tempering) → Finishing machining → Assembling → Painting → Testing → Packing

3. Product performance

- High level raw material to ensure the high quality of the bottom roller
- Surface hardening after quenching reach HRC45~52, increase the wear resistance of the wheel surface.
- Advanced CNC machine ensure the high machining accuracy
- Select the good sealing ring to avoid oil leakage
