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

A drive sprocket is one of the most important components in an excavator undercarriage system. It transfers power from the final drive motor to the track chain, allowing heavy equipment to move efficiently across different working environments. However, many operators experience problems such as excessive wear, track slipping, abnormal noise, and increased maintenance costs due to poor-quality or incorrectly matched drive sprockets.
A top roller is a critical component in an excavator’s undercarriage system, supporting the upper section of the track chain and helping maintain stable track movement. When a top roller wears out or fails, operators may experience abnormal track noise, uneven movement, increased fuel consumption, and expensive downtime. This article explains how top rollers work, why they matter, how to select the right component, and how professional solutions from Quanzhou Qiansheng Heavy Industry Machinery Co., Ltd. can help improve excavator reliability and operating efficiency.
