The track roller for U15 and EX17 mini excavators is an essential component of the undercarriage system. Its primary function is to carry the weight of the machine, guide the track chain, and maintain stable contact with the ground. By absorbing impact and distributing load evenly, it reduces wear on the track system and enhances machine stability. This roller is engineered not only to meet OEM specifications but also to perform reliably in demanding construction, landscaping, and utility projects.
Material & Heat Treatment
To achieve excellent wear resistance and long-term performance, the roller body and shaft are made from 40Mn and 45# alloy steel. Each piece undergoes induction heat treatment, achieving a surface hardness of HRC 52–58. This process enhances the roller’s resistance to abrasion, deformation, and fatigue, ensuring that it withstands continuous heavy loads and abrasive working environments such as rocky soil or wet ground.
Manufacturing Process
Our U15 / EX17 track rollers are produced through a strict six-step process to guarantee quality and consistency:
Heat Treatment
Improves hardness and surface wear resistance.
Machining Process
CNC precision machining ensures exact dimensions and smooth rotation.
Assembly
Integration of the shaft, body, bushings, and sealing components.
Running Test
Functional testing under load to confirm smooth operation and leak-free sealing.
Paint Spraying
Anti-rust coating applied for corrosion resistance and a professional finish.
Packing
Export-standard wooden cases or pallets to ensure safety during transportation.
OEM Compatibility & Fitment
The U15 / EX17 track roller is designed as a direct replacement for OEM parts, offering a perfect fit for both mini excavator models. This compatibility reduces the need for separate stocking, making it a practical choice for equipment dealers, distributors, and fleet managers. Customers are encouraged to provide the part number or machine serial number when ordering to confirm exact fitment
Quality Control & Inspection
Every roller undergoes comprehensive testing before shipment:
- Hardness inspection for surface and core strength.
- Dimensional accuracy checks to ensure correct fitment.
- Sealing performance testing to guarantee oil-tight protection.
- Dynamic running test under simulated working conditions.
This strict inspection process ensures every unit meets international quality standards and customer expectations.
Application Scenarios
The U15 / EX17 track roller is highly versatile and performs well in various applications:
- Urban construction – Compact excavators often work in tight spaces where stability is critical.
- Landscaping – Reliable undercarriage support for working on soft or uneven soil.
- Utility projects – Durable rollers for trenching, roadwork, and pipe laying tasks.
- General excavation – Smooth operation in different soil conditions, reducing downtime.
