Sealed and lubricated dozer chains/PPR structure/track link assy (assembly) /undercarriage chains
 
We are committed to providing qualified track chains with PPR structure according to OEM specifications.
Our full range of chains is well-proven in various industries (mining, forestry, quarry, construction, and agriculture, etc.) and available to fit all brands & models of excavators and clawer machines.
 
All components (pins, bushings and forged links) are produced with precise tolerance to ensure joint integrity, perfect fit and sealing. Meanwhile, they are fully quenched & tempered and induction hardened at the rail surface of links for higher wear resistance and longer service life.
Our lubricated dozer links are filled by oil to reduce internal friction and wear between pins and bushings for extended wear life under extreme working conditions. Every joint goes through stress test to reduce the risk of leakage while operating. The service life is improved by 30%-50% compared with that of greased type.
 
We can supply customized chains upon request such as heavy duty and extended wear life (EWL) chains with bigger bushings with deeper carburized thickness and higher links for maximum service life.

 
Advantages of CLIK lubricated tracks:

1. Fully quenched & tempered track links as per OEM specification and with typical hardness over HB360 and sharpy impact value over 39 J/cm².

2. Induction hardened rail surface of track links with hardness over HRC50 with enhanced wear resistance.

3. Carburized thickness over 3mm for bushings and hardness over HRC55.

4. Full hardened and tempered pins with typical hardness over HRC55 for best resistance to wear and fatigue.

5. Quality seals made branded European manufacturer to endure the working temperature over 200 degree.

6. Branded oil ensure extreme working temperature: -50℃-180℃.

7. PPR structure for D9 to D11 track link assembly.
