  • How Does a Track Bottom Roller Improve Excavator Undercarriage Performance?

    The track bottom roller is one of the most important components in an excavator undercarriage system. Although it works continuously under the machine, many operators only notice its importance when problems such as abnormal noise, track instability, excessive wear, or unexpected downtime occur. A high-quality track bottom roller supports the weight of the excavator, guides the track chain, reduces friction, and helps maintain smooth movement during heavy-duty operations.

  • Causes of oil leakage of excavator carrier roller-PC500 Track Roller

    Oil leakage of track rollers is mostly caused by damaged sealing components, followed by issues from assembly, machining, operating conditions and lubricating oil. The interior of a track roller is filled with gear oil, which relies on floating oil seals (dual‑metal rings plus O‑rings) for rotary sealing. Oil seepage or dripping will occur once the seal fails.PC1250 Track Roller
