As professional manufacturer and factory supplier Quanzhou Qiansheng Heavy Industry, we supply premium Track Link for Doosan DX225 200103-00096A made of high-density alloy steel via integral drop forging. Compared with ordinary aftermarket parts, our Doosan DX225 track link features stable pitch dimension, strong wear resistance and tight grease sealing structure, perfectly adapting to mining, quarry and construction heavy-duty working conditions. With ISO 9001 and CE certification, 2000+ working hours lifespan and strict full inspection, we support OEM wholesale, customized service and global fast delivery for worldwide distributors and contractors.

Doosan DX225 is a mainstream 20-ton class excavator widely used in urban construction, quarry mining, earthmoving and infrastructure engineering projects. As the core load-bearing part of the whole undercarriage system, Track Link for Doosan DX225 200103-00096A  undertakes the full machine weight, and bears long-term tensile force, sand abrasion and muddy water erosion in harsh working sites all year round.

 

As a direct local manufacturer in Quanzhou construction machinery parts base, we independently produce and supply Track Link for Doosan DX225 200103-00096A. Our core advantage is fundamentally solving the common problems of ordinary track links on the market: easy pitch elongation, loose chain body, internal wear fast and early fracture, effectively extending the overall service life of the excavator undercarriage and reducing your later maintenance replacement cost.

Factory Forging Process and  Core Advantage

Many ordinary aftermarket Track Link for Doosan DX225 200103-00096A adopt secondary recycled steel and simple stamping forming. The internal structure is loose with pores, pins and bushings without overall heat treatment. After a short period of use, it is easy to appear chain stretching, pitch deviation, then accelerate the wear of supporting roller, idler and sprocket, bringing unplanned downtime losses.

We follow ISO 9001:2015 quality management system strictly, all Doosan DX225 track links adopt one-piece precision drop forging. The internal metal grain is dense and arranged uniformly, greatly improving structural toughness and impact resistance. Every batch of raw materials and finished products will pass ultrasonic testing and magnetic particle flaw detection , no crack, no sand hole, quality traceable one by one.

In the link assembly process, we use high-tonnage hydraulic press to press fit high-carbon steel pin and deep quenched bushing. Equipped with imported heavy-duty polyurethane sealing ring, it can lock internal lubricating grease for a long time, isolate external sand, dust and muddy water from entering the gap. This practical structural design can minimize pin and bushing internal friction, keep track pitch stable for a long time, and avoid frequent track adjustment.

FAQ

Q: Can I buy only the single Track Link for Doosan DX225 200103-00096A without track shoes?

A: We support flexible purchasing options. You can order separate track link assembly to match your existing track shoes, or choose the complete track group with pre-installed track shoes and high-strength bolts, directly installed and used without secondary processing.

Q: What causes track chain stretching, how do your products solve it?

A: The so-called chain stretching in actual use is caused by the wear gap between pin and bushing. We use overall deep quenching to improve pin and bushing hardness, plus fully sealed dustproof structure to block abrasive impurities, reduce internal wear fundamentally, and keep track pitch stable for long-term operation.

Q: What is your after-sales warranty if the track link breaks due to quality problem?

A: All our Track Link for Doosan DX225 200103-00096A enjoy 1 year or 2000 working hours warranty. Once verified as manufacturing defect, we provide free one-to-one replacement in your next order, fully guarantee the rights and interests of bulk procurement customers.
