Our Long wear parts@ supply high quality Komatsu extreme duty rock bucket/Komatsu reinforced rock bucket/Komatsu extreme service rock bucket/Komatsu Excavator mining rock bucket /Komatsu custom excavator bucket.
We use high-grade, abrasion-resistant steel (such as Hardox 400/450 or equivalent) in high-wear zones—the floor, side cutters, and cutting edge. For extreme applications (granite, basalt, or slag), we offer optional wear packages with bolt-on wear plates and replaceable shrouds that extend service life by up to 50% compared to standard mild steel buckets. Every bucket is also fitted with our signature wear indicator system so your maintenance team can plan replacements proactively, not reactively, eliminating unplanned downtime.
In rock quarries and demolition sites, buckets face constant shock loading from falling boulders and hydraulic hammering. Our buckets are fabricated with double-walled construction at stress points (heel and side plate junctions) and reinforced with ribbed gussets. All critical welds are performed by certified welders and undergo non-destructive testing (NDT) to guarantee zero porosity or cracking. We also offer a full-wrap heel guard that deflects impact energy away from the bucket’s back plate—a common failure point in competitor products.
Inconsistent bucket geometry—even a few millimeters off—can change the entire digging angle and cause uneven tooth wear. We maintain strict production controls: all cutting, rolling, and welding jigs are numerically controlled (CNC), and every finished bucket is dimensional-checked against a master template. Our factory operates with buffer stock of critical steel grades, enabling us to fulfill bulk orders (20+ units) with identical specifications across batches. For long-term contracts, we reserve production slots and raw materials in advance, so your project timelines are never held up by supply gaps.
All mining buckets come with quality warranty to eliminate your after-sales worries.Professional technical team offers model matching & installation guidance free of charge.

| Preparation Tools | Pin shaft, cotter pin, hammer, pry bar, grease gun |
| Step 1 | Park the excavator on flat solid ground, lower the stick arm to let the old bucket fully touch the ground, turn off the engine and release residual hydraulic pressure of boom. |
| Step 2 | Knock out cotter pins on two connecting pins (bucket-stick arm & bucket-cylinder) with a hammer, push out two main pins by pry bar and remove the old bucket safely. |
| Step 3 | Horizontally hoist the new bucket, align pin holes of bucket lugs with pin holes of stick arm and bucket cylinder, keep pin holes concentric. |
| Step 4 | Install the upper pin (connect bucket cylinder & bucket ear) first, assemble cotter pin to lock the pin to prevent slipping. |
| Step 5 | Install the lower main pin (connect stick arm & bucket lug), fit cotter pin for locking and fixing. |
| Step 6 | Inject grease into grease nozzles of two pin shafts with a grease gun until clean grease extrudes from the gap between pin and lug. |
| Step 7 | Start the excavator slowly, lift & lower the bucket repeatedly to test rotation flexibility, begin construction if no jamming occurs. |
| Important Notes | 1. Never start the engine when your body is between stick arm and bucket to prevent clamping injury.2. Cotter pins must be fully installed; missing cotter pins may cause pin falling off and bucket dropping.3. Refill grease for pin shafts every 8 working hours to extend service life. |
