The excavator track idler bushing is a crucial component in the undercarriage system of an excavator. It plays a vital role in supporting and guiding the movement of the excavator's tracks, ensuring smooth and reliable operation.
Constructed from durable materials such as cast iron or steel, the excavator track idler bushing is designed to withstand the heavy loads and rigorous operating conditions encountered in excavator work. Its robust design ensures it can handle the constant abrasion and impact from the moving tracks.
The excavator track idler bushing is mounted on the idler wheel, which rotates to guide the tracks around the excavator's frame. As the excavator moves, the tracks roll over the idler wheels, and the bushings provide a smooth and consistent surface for the tracks to move on.
Over time, the excavator track idler bushings may wear down due to abrasion and impact. Regular inspection and replacement of worn bushings are essential to maintain the excavator's undercarriage system in good working order.
In summary, the excavator track idler bushing is an important component that supports and guides the excavator's tracks, ensuring smooth and reliable operation. Its robust design and durability make it a crucial part of the excavator's undercarriage system.

720 is a bimetal bearing with steel back and sintered CuPb24Sn4 as lining. This type has fairly good performance in anti-fatigue and heavy load capacity. It is suitable for middle-speed and middle load. When the soft alloy is plated on the bushing surface and with oil lubrication, it can be applied in the high-speed internal combustion engine and connect-rod.
