Product Description
Our line boring excavator bucket is a portable on-site machining system designed to accurately restore worn or deformed bucket pin bores without transporting the bucket from the job sites to workshops.
Why Bucket Bores Repair Are Common Problems
As we know, the bucket is one of the most critical components of an excavator for digging, loading, and material handling under continuous heavy impact and abrasion.
Bucket connection bores are particularly prone to wear, tear, deformation, and misalignment due to continuous high loads, shock forces, and abrasive working. Once these bores lose accuracy, the bucket becomes unstable, the pins and bushings wear faster, and the overall digging efficiency is decreased.
By performing precision line boring directly on site, the original bore geometry and alignment can be restored, the bucket is regained proper pin fit, smooth movement, and structural integrity.

FAQ
Q: What is the price range of line boring excavator bucket?
A: The price range of the boring kit is from USD2,616 to USD 3,016. The final price is based on the configuration, bore size range, and accessories of machine.
Q: What is line boring for excavator buckets?
A: Line boring for excavator buckets is a portable on-site machining process used to restore worn or deformed bucket pin bores to their original size and alignment.
Q: Why do excavator bucket bores wear faster than other joints?
A: Bucket bores are exposed to high impact loads, abrasive materials, misalignment forces, and harsh working environments, which will cause accelerated wear and deformation.
Q: Can bucket line boring be performed on site?
A: Yes. The system is designed specifically for on-site bucket repair, eliminating the need of transport large and heavy buckets to a workshop.
Q: What accuracy can be achieved after bucket line boring?
A: Line boring restores bore diameter, roundness, and alignment to meet original fit requirements for pins and bushings.
Q: Is welding required before line boring bucket bores?
A: If bore wear exceeds tolerance, welding buildup is performed first, followed by precision line boring to restore size and alignment.
