Product Function and Operating Principle of E325
The E325 track roller, also known as a bottom roller, supports the weight of the excavator while guiding the track chain during operation. It ensures proper tension, reduces vibration, and enables smooth movement on rugged or uneven terrain. This roller is engineered for long-lasting durability in heavy-duty and mining environments.
Materials and Heat Treatment of CAT Track Rollers
Manufactured using premium 45# steel for the shaft and high-strength alloy steel for the roller body, including options like 40Cr or 42CrMo. The components undergo deep surface hardening via induction quenching, achieving a hardness level of HRC 52-58 for the tread area to enhance wear resistance and extend service life under extreme load.
How We Manufacture the E325 Track Roller
Each E325 track roller is forged, machined, heat-treated, and assembled in-house with strict precision.
- Forging and CNC machining of roller shell
- Shaft grinding and press fitting
- Heat treatment with hardness testing
- Final assembly and seal installation
- 100% quality inspection before packing
