Extended Service Life and Superior Durability
Our track rollers are engineered with carefully selected materials and advanced processing techniques to ensure long-lasting performance:
- The roller is made from forged 40MnB2 high wear-resistant boron steel, heat-treated to a surface hardness of HRC 48-55 with a hardening depth of 8-10mm, delivering excellent wear resistance.
- The center shaft is forged from 42CrMo alloy steel, with a surface hardness of HRC 48-55 and core hardness above HRC 28, providing both wear resistance and high fracture toughness.
- The shaft surface is precision polished by CNC machining to minimize wear on the internal copper bushing during operation.
- Pure copper bushings are used internally to enhance wear resistance, while high-density sealing rings protect the internal structure from dust, sand, and moisture intrusion.
Track Rollers function The function of the track roller is to convey the weight of an excavator to the ground . When an excavator is run on uneven ground, track rollers carry a tremendous impact. Therefore, the support of track roller is huge. Moreover, if it is of poor quality and is often dusty, it needs a very good sealing to prevent dirt, sand and water from damaging it.
