Kinton Parts is trusted by professionals worldwide for delivering high-quality parts for excavators, bulldozers, and other construction machinery—with guaranteed performance and durability.
The Caterpillar E350 track roller is one of the primary load-bearing components within the excavator undercarriage system. Positioned beneath the track frame, it supports the operating weight of the machine while guiding the track chain during travel and excavation. As a heavy-duty replacement track roller for CAT E350 excavators, this component plays a critical role in distributing machine weight evenly across the undercarriage.
For machines working in road construction, quarry operations, foundation projects, and large-scale earthmoving applications, a durable track roller is essential for maximizing productivity and minimizing downtime.
Materials and Heat Treatme
Each E350 track roller undergoes a carefully controlled production process to ensure consistent quality and dependable performance.
Heat Treatment
The roller shell and key load-bearing components undergo advanced heat treatment to improve surface hardness, wear resistance, and impact strength. This process helps the track roller withstand continuous heavy loads and harsh operating conditions while extending its service life.
Machining Process
The roller body, shaft, bushings, and internal components are processed using CNC machining equipment to ensure accurate dimensions and tight tolerances. Precision machining improves assembly accuracy, smooth rotation, and overall operational reliability.
Assembly
Each track roller is assembled with high-quality shafts, bushings, seals, and lubrication components. Strict assembly procedures ensure proper fitment, effective sealing performance, and long-term durability under demanding excavation conditions.
Running Test
Every assembled roller undergoes rotation and performance testing to verify smooth operation, lubrication retention, and sealing integrity. This inspection process helps ensure consistent quality before shipment.
Paint Spraying
After inspection, the roller receives an anti-corrosion coating and protective paint treatment. This process improves resistance to rust, moisture, and environmental exposure during transportation, storage, and field operation.
Packing
Following final quality checks, the finished track rollers are carefully packed using export-standard packaging materials. Proper protection during transportation helps ensure the products arrive safely and are ready for installation upon delivery.
