Import Cat Bulldozer Undercarriage Parts — Buy in Bulk from Supplier in China

A&S Undercarriage Co., Ltd. supplies a complete range of Cat bulldozer undercarriage components for models such as D3K2, D4K2, D5K2, D6K, D6K2, D6N, D6T and D7E. The catalogue includes track shoes or pads, track chains and link assemblies, front idlers, bottom rollers, carrier rollers, driving sprockets, bolts and nuts, and tension springs. All parts are manufactured to match the original equipment specifications published by Caterpillar for each model. The supplier highlights the ability to produce items according to customer drawings or sample pieces.

Typical material for these components is high‑strength alloy steel, often grade 4140 or equivalent, which offers a good balance of tensile strength and wear resistance. Components are commonly heat‑treated to a hardness of 28‑32 HRC, a standard practice for undercarriage parts that endure heavy loads. Standard bolt sizes range from M12 to M24, with thread pitches conforming to ISO metric standards. Tension springs are usually fabricated from spring steel with a working load of 2 000 - 5 000 kg, a typical capacity for Cat bulldozer models.

These parts are primarily used by construction contractors, mining operators and equipment rental firms that maintain Cat bulldozers in demanding environments. A&S can accommodate both small‑batch replacements and large‑scale bulk orders, and it offers custom machining based on supplied CAD drawings. Shipping can be arranged under FOB or CIF terms, allowing buyers to select the most suitable logistics arrangement. Prospective buyers should verify the exact model number, part numbers and any required heat‑treatment specifications before confirming an order.

A&S Undercarriage Co., Ltd. is based on the 2nd Floor of the Xinhe Linghang Building in Chengdu, Sichuan (postal code 610000). The company is recorded as an imported supplier with a harbor trust tier, and its response rate and average response time are currently shown as zero, indicating that communication may need proactive follow‑up.

The firm specialises in providing undercarriage, excavator and bulldozer track systems, offering both standard catalog items and custom‑engineered solutions. It employs experienced engineers who can adapt designs to customer drawings, samples or conceptual requirements, and it supports a range of logistics options for domestic and international buyers.
