Heavy-Duty Undercarriage Rollers for Excavators & Dozers
Product Description
The undercarriage accounts for a significant portion of a tracked machine's maintenance costs. Worn or failed rollers can lead to excessive track wear, de-tracking, and costly downtime.
Yile Machinery manufactures high-quality aftermarket track rollers and carrier rollers designed to withstand the toughest working conditions. Our rollers provide reliable performance and extended service life for a wide range of excavators, bulldozers, and other tracked heavy equipment.
The Difference: Track Rollers vs. Carrier Rollers
We supply both primary types of undercarriage rollers:
Track Rollers (Bottom Rollers): These are mounted to the bottom of the track frame and carry the full weight of the machine. They are designed to handle immense loads and constant abrasion as they guide the track along the ground. We offer both single-flange and double-flange track roller designs.
Carrier Rollers (Top Rollers): Mounted on the top of the track frame, their function is to support the weight of the track as it returns to the front idler. They prevent excessive track sag and ensure smooth operation.
Manufacturing for Maximum Durability & Wear Resistance
The lifespan of a roller is determined by the quality of its materials and manufacturing process. Our rollers are engineered to last.
Forged Roller Shell: The roller body is forged from high-manganese alloy steel (e.g., 50Mn) . Forging creates a dense, refined grain structure that is far superior to casting in terms of impact strength and fatigue resistance.
Specialized Heat Treatment: The roller's tread surface undergoes a crucial induction hardening process. This creates a deep, hardened layer with a surface hardness of HRC 52-58, providing exceptional resistance to wear from contact with the track links. The core remains tough to absorb shock loads.
Precision Assembly: Each roller is assembled with a high-strength shaft, bronze bushings, and high-performance duo-cone (floating) seals. This advanced sealing system prevents dirt and moisture from entering while locking in lubrication for a maintenance-free service life.
Key Features & Benefits
Extended Wear Life: Forged bodies and deep induction hardening significantly reduce wear and extend the time between undercarriage rebuilds.
Reduced Operating Costs: Durable, long-lasting rollers minimize downtime and lower the total cost of ownership.
Superior Sealing: High-performance seals protect internal components from abrasive contaminants, preventing premature failure.
Perfect Fit: Manufactured to precise OEM specifications for easy installation and compatibility with your existing undercarriage components.
