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.
Quanzhou Qiansheng Heavy Industry Machinery Co., Ltd. recently participated in the Bauma China exhibition in Shanghai, one of the world’s leading construction machinery trade shows. During the exhibition, we showcased our latest undercarriage parts for excavators and bulldozers, including track rollers, carrier rollers, idlers, sprockets, and track chains.
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
For procurement managers, maintenance supervisors, and equipment dealers, the selection of undercarriage components—track rollers, idlers, sprockets, and track chains—represents a significant operational expense. The decision between original equipment manufacturer (OEM) parts and aftermarket alternatives often involves balancing initial cost against long-term durability and machine uptime.
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 the machine to move efficiently under different working conditions. However, many operators and equipment owners experience problems such as premature wear, track slipping, abnormal noise, and increased maintenance costs caused by unsuitable or low-quality drive sprockets.
