Product Description
Yile Machinery is an OEM foundry specializing in the manufacture of high-strength excavator track links. As the backbone of the track chain assembly, our track links are cast from premium alloy steel and heat-treated to withstand the extreme stresses and abrasive wear encountered in mining, quarrying, and heavy construction environments.
We produce both standard replacement links and offer custom (non-standard) manufacturing for any make or model of excavator.
The track link is the fundamental building block of an excavator's undercarriage. Each link connects to the next with a pin and bushing, forming the track chain that carries the entire weight of the machine. A high-quality track link must:
Bear immense tensile loads as the excavator propels itself.
Resist severe abrasive wear from dirt, sand, and rock.
Endure constant impact and high-pressure contact with rollers and idlers.
Failure of a single track link can disable the entire machine, making the quality of this component absolutely critical for operational reliability.
We combine advanced materials and multi-stage processing to create a track link with exceptional service life.
Material Selection: We start with high-strength, wear-resistant cast alloy steel (e.g., 35CrMo or equivalent grades), which is specifically designed for high-impact and heavy-load applications.
Precision Casting: Our casting process ensures a dense, internally sound link free from porosity or defects. This provides the fundamental strength required to resist cracking and deformation.
Critical Heat Treatment (Induction Hardening): This is the most important step. The "rail" surface of the track link (where the rollers make contact) and the pin bores are subjected to a precise induction hardening process. This creates an extremely hard, wear-resistant surface while leaving the core of the link tough and ductile to absorb shock loads.
Precision CNC Machining: All contact surfaces and pin bores are machined to exact specifications, ensuring perfect alignment and fitment with pins, bushings, and track shoes.
Rigorous Quality Control: Every link is inspected for chemical composition, hardness depth and value, and dimensional accuracy before shipment.
A key part of our service is the ability to produce custom or "non-standard" track links. If you operate older, rare, or specialized machinery, finding replacement undercarriage parts can be difficult and expensive. We can help.
We can manufacture durable, high-performance track links based on:
An OEM part number
A detailed technical drawing
A physical sample to reverse-engineer
We have the capability to produce track links for virtually any excavator, including models from Caterpillar, Komatsu, Hitachi, Volvo, Doosan, and many others.
