Heavy-Duty Excavator Track Rollers (Bottom Rollers)

Yile Machinery manufactures high-performance, aftermarket excavator track rollers engineered to deliver exceptional durability and extended wear life in the toughest operating conditions. As a critical component of the undercarriage system, our bottom rollers are built to withstand high-impact loads and abrasive environments, ensuring your equipment stays productive and operational.

The Foundation of a Reliable Undercarriage: Superior Manufacturing

The lifespan of a track roller is determined by the quality of its materials and the precision of its manufacturing process. We produce rollers that meet or exceed OEM standards by focusing on three key areas:

1. Superior Strength through Forging

Unlike weaker cast iron alternatives, our roller shells are forged from high-strength alloy steel (such as 40Cr or 50Mn) . The forging process creates a dense, directional grain structure that provides superior impact resistance and prevents cracking under heavy loads.

2. Advanced Induction Hardening

The roller tread surface is subjected to a precise induction hardening process. This creates a deep, uniform hardened layer (HRC 52-58) for exceptional wear resistance against the track chain, while the core of the roller remains ductile to absorb shock.

3. High-Performance Sealing

Each roller is fitted with high-quality seals (e.g., dual-cone seals) to guarantee lifetime lubrication. This robust sealing system prevents lubricant loss and protects internal components—like the shaft and bronze bushings—from abrasive materials like dirt, sand, and water.
