Roaders: Carrier Wheel, Track Roller & Bottom Roller
Carrier Wheel
The carrier wheel, also called the top roller, supports the upper section of the track chain and keeps the track aligned during movement. It helps distribute weight evenly and reduces stress on the undercarriage system.
Track Roller
Track rollers are installed at the bottom of the undercarriage to bear the full weight of the excavator and guide the track chain smoothly along the ground. They are manufactured with wear-resistant steel to ensure durability under heavy loads.
Bottom Roller
Bottom rollers work in pairs with track rollers to stabilize the track assembly and absorb impact from uneven terrain. Their robust design minimizes vibration and improves machine stability during operation.
Complete Roader Set
Together, the carrier wheel, track rollers, and bottom rollers provide reliable track guidance, reduced wear, and extended undercarriage service life for XCMG excavators.

Guide Wheels: Idlers, Track Idlers & Tensioning Wheel
Idlers
Idlers are positioned at the front or rear of the undercarriage to guide the track chain and maintain proper alignment during operation. Their large diameter design reduces track wear and improves machine stability.
Track Idlers
Track idlers serve as a buffer between the track chain and other undercarriage components, absorbing impact and minimizing vibration. They help ensure smoother movement and longer service life for the track assembly.
Tensioning Wheel
The tensioning wheel, also known as the recoil or adjusting wheel, maintains the correct track tension. By preventing slack and excessive tightness, it protects the track assembly from premature wear and reduces downtime.

Drive Wheels: Sprocket & Track Sprocket
Sprocket
The sprocket is the primary driving wheel of the excavator undercarriage. With precision-cut teeth, it meshes directly with the track links to transfer engine power into forward or reverse movement. Built from high-strength steel, the sprocket delivers durability and reliable performance under heavy loads.
Track Sprocket
The track sprocket is specifically designed to fit the excavator’s track chain system, ensuring accurate engagement with the links. Its hardened teeth resist wear and deformation, extending the service life of both the sprocket and the track chain.
Complete Drive Wheel System
Together, the sprocket and track sprocket provide the driving force of the excavator, enabling efficient operation, reduced downtime, and smooth power transmission in the most demanding working environments.
Other Chassis Parts: Pins, Pin Shafts & Kingpin Shafts
Pins
Pins are essential connectors in the excavator’s chassis and undercarriage system, securing key components while allowing controlled movement. They are engineered with high-strength materials to resist bending and wear under heavy loads.
Pin Shafts
Pin shafts provide structural support and precise alignment between moving parts. Their hardened surfaces ensure long-lasting durability, reducing the risk of deformation and premature failure.
Kingpin Shafts
Kingpin shafts serve as pivotal joints within the chassis assembly, enabling smooth articulation and reliable load distribution. Built for strength and stability, they are critical to maintaining safe and efficient machine performance.
Complete Chassis Support
Together, these components form the backbone of the excavator’s chassis, ensuring secure connections, reduced wear, and long-term reliability across demanding job conditions.

Undercarriage Maintenance Guide
Signs You Need to Replace Your Undercarriage
Excessive Track Sag – If the track chain sags more than recommended, it indicates stretched or worn links.
Uneven Wear on Rollers or Idlers – Flat spots, cracks, or oil leakage show the part has reached its service limit.
Worn or Broken Sprocket Teeth – Sharp, hooked, or missing teeth reduce engagement and damage the track chain.
Reduced Machine Stability – If your excavator feels unstable or vibrates excessively, the undercarriage may be compromised.
Frequent Track Adjustment – Constantly tightening the track tension is a strong signal of wear.
How to Measure Undercarriage Wear
Track Chain Wear – Use a caliper to measure link height and compare with manufacturer specifications.
Sprocket Wear – Check the tooth profile; sharp or pointed teeth indicate excessive wear.
Roller and Idler Wear – Measure flange thickness and diameter, ensuring they meet minimum service standards.
Track Shoe Wear – Inspect the grouser height; low or uneven grousers reduce traction and need replacement.
Overall Wear Percentage – Keep track of wear records over time to predict replacement intervals and reduce downtime.
