Kinton Parts is trusted by professionals worldwide for delivering high-quality parts for excavators, bulldozers, and other construction machinery—with guaranteed performance and durability.
The bucket adapter (also known as the tooth holder or base) is the interface between the excavator bucket and the replaceable bucket tooth. In Komatsu machines such as PC200, PC300, and PC400, the adapter is welded directly to the bucket lip and endures constant digging impact, stress, and vibration.
A worn or poorly fit adapter can lead to loose teeth, premature pin wear, and even structural damage to the bucket. Our forged Komatsu adapters ensure proper tooth alignment, optimal load transfer, and fast replacement in the field.
Available Types & Common Fitments
We supply Komatsu bucket adapters for a wide range of PC-series excavators and working conditions:
| Adapter Model | Fitment Example | Machine Class | System Type |
|---|---|---|---|
| PC60 / PC75 | Light-duty buckets | Mini/midi (6–8 tons) | Vertical/Side Pin |
| PC200 / PC210 | Standard buckets | 20-ton machines | Side Pin / Weld-on |
| PC300 / PC360 | Rock buckets | 30–36 ton class | HD Adapter Nose |
| PC400 / PC450 | Quarry buckets | 40–45 ton class | Reinforced HD |
Pin and retainer slots match Komatsu-standard teeth such as 205-70-19570, 207-70-14151, etc.
Installation Guidance
These adapters are weld-on type, and must be securely installed by experienced welders:
- Clean the welding surface and adapter base thoroughly
- Preheat thick buckets before welding (especially above 20mm lip thickness)
- Use low-hydrogen rods or flux-cored wire with multiple pass welds
- Allow controlled cooling after welding to reduce stress fractures
We provide installation drawings or seat dimension charts upon request.
Tooth + Adapter + Pin Installation Example
Shown below is a complete assembly with Komatsu-style tooth, adapter, and locking pin. This system allows fast field replacement of worn teeth while keeping the welded adapter in place—saving time and lowering maintenance costs.
Material & Heat Treatment
Our Komatsu adapters are made from 30CrMnSi alloy steel, a structural-grade material offering high tensile strength, excellent fatigue resistance, and superior weldability.
Raw Material Preparation
High-quality alloy steel is carefully selected and prepared to ensure excellent toughness, wear resistance, and impact strength. Strict material inspection helps guarantee stable product quality from the beginning of the manufacturing process.
Forging Process
The bucket teeth undergo high-temperature forging to improve internal density and structural strength. This process enhances resistance to heavy impact and reduces the risk of cracking during demanding excavation operations.
Precision Molding Process
Advanced molding technology is used to create accurate tooth profiles and consistent dimensions. Proper molding ensures better penetration performance and stable compatibility with bucket adapters and locking systems.
Pin Hole Drilling
Precision drilling is performed on the bucket tooth pin hole to ensure accurate installation of locking pins and retainers. This process improves assembly stability and helps prevent tooth loosening during operation.
Surface Treatment
The bucket teeth receive specialized surface treatment to improve wear resistance and remove impurities from the surface. This process also enhances durability under abrasive working conditions such as mining and rock excavation.
Painting & Protective Coating
After final inspection, each bucket tooth is coated and painted to provide anti-rust protection during storage and transportation. The protective coating also improves product appearance and surface durability.
