YINTAI MACHINERY – Your Trusted Partner for Excavator & Bulldozer Undercarriage Parts
When it comes to construction machinery spare parts, reliability and quality are non‑negotiable. For nearly three decades, Xiamen Yintai Machinery Co., Ltd. (YINTAI) has been a leading manufacturer of high‑performance undercarriage components for excavators and bulldozers. From small‑sized machines to giants like the PC2000, EX1900, D11, D10, D475, and D375, we deliver precision‑engineered parts that keep your equipment running in the toughest conditions.
Located in Xiamen, China, YINTAI is a professional enterprise integrating casting, forging, and precision machining. We operate one of the largest sand casting lines in China, alongside advanced precision casting equipment and dedicated production lines for engineering machinery parts. Our strategic partnerships span industry leaders in Italy, the United States, South Korea, Japan, and China – a testament to our world‑class manufacturing capabilities.
With over 20 years of entrepreneurial expertise, we specialise in chassis components for both medium and large excavators and bulldozers. Our commitment to professionalism, precision, and agility has earned us long‑term trust from customers worldwide.
We manufacture a comprehensive portfolio of undercarriage parts, designed to meet the most demanding operational requirements:
- Track Link Assemblies – Forged from 35MnB or 40Mn2 special steel, with advanced heat treatment and a self‑lubricating system for extended bearing life.
- Track Rollers & Carrier Rollers – Available in 40Mn2, 40MnB, and 50Mn. Precision‑forged and heat‑treated to HRC 52‑62 with a hardened depth of 7‑10 mm. Our unique MAZAK CNC machining after welding eliminates concentricity errors, boosting service life by over 40%.
- Idlers – Cast with alkali‑phenolic resin sand or roll‑forged, reaching surface hardness of HRC 48‑58 and a hardened layer of 4‑6 mm. Processed on large‑scale CNC vertical lathes for perfect dimensional accuracy.
- Sprockets – Sand‑cast using materials like G33MnCrMo5, G33Mn4, and ZG40Mn, hardened to HRC 48‑54 with a case depth of 5‑10 mm for excellent wear resistance.
- Track Shoes – Over 1,100 models available (pitch 90‑317.5 mm), including single, double, triple grouser, and specialised swamp shoes for excavators and cranes.
- Segments – Forged from high‑performance steel with thickened tooth faces and precision heat treatment for maximum durability under extreme loads.
- Wear Parts – Full range of cutting edges, end bits, ripper shanks, and lip shrouds for bulldozers, loaders, and graders.
- Track Adjusters – Built with high‑quality special steels and advanced sealing systems for leak‑proof, stable operation.
All products undergo rigorous quality inspection from raw material to finished part, ensuring consistent performance and longevity.
We are an official OEM supplier for BERCO and ITR – two global leaders in the undercarriage industry. This recognition speaks volumes about our quality standards and production reliability.
Our investment in imported MAZAK machining centres (from Japan’s premier CNC manufacturer) guarantees exceptional precision, concentricity, and repeatability – crucial for heavy‑duty applications.
We operate one of China’s largest sand casting lines, capable of producing parts for the largest machines on the market – including PC2000, EX1900, D11, D10, and D475 series. Our precision casting equipment ensures every component meets strict dimensional and metallurgical standards.
Every product is subject to a comprehensive inspection process – from chemical composition analysis to final dimensional checks. This ensures that our parts not only meet but often exceed OEM specifications.
Our team combines deep technical knowledge with hands‑on manufacturing expertise, enabling us to provide tailored solutions and responsive service to customers worldwide.
YINTAI parts are engineered to perform in extreme environments – from scorching deserts to freezing climates (‑45°C to 120°C). Our track rollers and carrier rollers, for example, are designed to work maintenance‑free under severe conditions, thanks to high‑quality floating seals and advanced lubrication systems. The result is reduced downtime, lower operating costs, and peace of mind for your fleet.
Whether you operate a small excavator or a massive mining dozer, YINTAI MACHINERY offers the parts, quality, and service you need to keep your business moving forward. We are committed to continuous innovation and excellence – because we believe in crafting excellent parts and a bright future.
