The XCMG XE215 carrier roller, commonly referred to as upper track roller or top roller, is a precision forged undercarriage component designed exclusively for the XCMG XE215 standard excavator track system. Adopting one-piece integral forging molding, this roller avoids the internal porosity, loose texture and structural fragility common in ordinary cast rollers.
As a core track support part, it bears the weight of the upper track chain, maintains straight track operation, and relieves track sagging and lateral deviation during equipment running. Manufactured strictly according to original equipment dimensional standards, it features complete dimensional consistency and direct interchangeability for routine part replacement and undercarriage maintenance.
This XCMG XE215 upper track roller is made of standard 35MnB alloy steel, a dedicated material for engineering machinery undercarriage parts with stable structural density and reliable impact resistance. The roller surface adopts medium-frequency integral induction quenching treatment, forming a uniform 6-9mm hardened layer, with stable surface hardness of HRC 53-59, matching the wear resistance requirements of medium-duty excavator operation.
The built-in thickened tin bronze bushing ensures smooth mechanical coordination and low friction operation. Each finished roller passes magnetic particle flaw detection and air tightness inspection to exclude internal cracks, hidden defects and oil leakage risks, ensuring stable structural performance for long-term cyclic work.

Tailored for the working characteristics of XCMG XE215 excavators, this precision forged carrier roller adapts to ambient temperatures ranging from -35℃ to +85℃. It fits daily medium-load engineering scenarios, including municipal earthwork, highway foundation construction, gravel site operation, water conservancy dredging and general quarry construction.
Optimized for frequent walking and steering movements of excavators, it delivers better impact resistance and surface wear resistance than ordinary cast rollers. Under standard working load and regular maintenance, the roller can achieve a stable service life of over 2200 working hours, effectively reducing frequent undercarriage part failures.
- Different from conventional general-purpose track rollers, this XE215 carrier roller is specially calibrated for XCMG XE215 track assembly parameters, with no universal model error
- The integral forging process eliminates the risk of shell cracking and layer separation that easily occurs in welded and cast rollers
- The sealed oil circuit structure reduces dust, mud and water intrusion in daily working environments, maintaining consistent lubrication effect
- Standardized processing and strict finished product testing ensure stable and consistent performance of each roller, suitable for daily equipment replacement and regular undercarriage maintenance
