Product Description
Our line boring bucket system is suitable for standard buckets, rock buckets, mining buckets and heavy-duty and reinforced buckets which is made from heavy-duty bucket materials. It is a cost-effective and practical repair solution for bucket pin bore machining.
Portable line boring solution is for accurate on-site repair of excavator bucket pin bores. It provides on-site repair feasibility for excavator bucket bore repair. Timely repair protects critical components from excessive wear and tear and prevents damage to other parts.
On-site bucket line boring delivers accurate, fast, and cost-effective restoration of critical excavator bucket connections. It can achieve high precision bore restoration as it is done in machine shops.
With our line boring excavator bucket system, it ensures you can do accurate bucket bore restoration from standard earthmoving to extreme mining conditions.
Why Bucket Bores Wear Faster
- High Impact and Cyclic Loads
- Abrasive Working Environment
- Misalignment Under Heavy Force
- Insufficient Lubrication
- High Strength and Rigid Materials

On-Site Line Boring Bucket Repair Procedure
- Inspection & Measurement
Assess wear, ovality, and alignment of bores. Measure bores diameter and clearance for determining repair requirements.
- Preparation & Setup
Remove worn pins and bushings. Mount the line boring system directly onto the bucket structure.
- Alignment
Precisely align the boring bar to ensure correct coaxial positioning of all bucket bores.
- Machining / Line Boring
Perform precision line boring to restore bore geometry.
If required, welding buildup is completed before final machining.
- Final Machining & Inspection
Finish bore machining to target size and tolerance. Inspect alignment and surface finish.
- Reassembly & Testing
Install new pins and bushings. Verify smooth bucket movement and stable operation.
Multi-Application Machining Capabilities
- Bucket linkage and H-link bores
- Side ear and lug connection bores
- Correction of bore misalignment caused by long-term wear
- Restoration of original bore size after welding buildup if it is required
- Accurate alignment on large, heavy bucket structures
- Controlled cutting on thick and high-strength materials
Packaging Way
Standard export wooden box
Shipping Way

FAQ
Q: What materials are excavator buckets typically made of?
A: Excavator buckets are commonly made from high strength steel or wear-resistant steel for withstanding heavy load and abrasion.
Q: Can hardened or thick bucket materials be machined?
A: Yes. The line boring system is capable of machining thick-walled and high strength bucket structures used in heavy duty applications.
Q: How long does a typical bucket line boring repair take?
A: Repair time depends on bore size and wear level, but on-site line boring is significantly faster than traditional repair methods.
Q: How does bucket line boring compare with traditional repair methods?
A: No bucket transportation required
Reduced downtime and labor cost
Faster turnaround and lower total repair cost
Q: How much is your line boring bucket system?
A: The price range of our line boring bucket system is from USD2,617 to USD 3,017.
Q: Is bucket line boring cost-effective compared to bucket replacement?
A: Yes. Line boring extends bucket service life and avoids costly bucket replacement, offering a high return on investment.
