Bucket Tooth and Accessory are important components for excavating machinery and have many advantages and wide applications. First of all, the bucket teeth are made of high-quality alloy steel materials, which have wear resistance and impact resistance and can be used for a long time in harsh environments. Secondly, the design of the bucket teeth has been precisely optimized to effectively improve excavation efficiency and operating efficiency. In addition, the bucket teeth and accessories have good adaptability and replaceability, and can be selected and replaced according to different operating requirements and geological conditions.
Bucket teeth and accessories are widely used in civil engineering, mining, construction and agriculture. In civil engineering, bucket teeth are used in mechanical equipment such as excavators and loaders to excavate earth, shovel materials and clean construction sites. In the mining industry, bucket teeth are used in equipment such as excavators, crushers and loaders to mine, crush and load ore. In construction projects, bucket teeth are widely used in equipment such as excavators, bulldozers, and road rollers to excavate foundation pits, smooth roads, and compact land. In agriculture, bucket teeth are used on equipment such as excavators, harvesters and cultivators to clear land, harvest crops and treat farmland.
In general, bucket teeth and accessories are widely used in excavation and loading operations in various industries due to their wear-resistant, efficient and reliable characteristics. They improve the operating efficiency and performance of mechanical equipment and provide reliable support and guarantee for the development and construction of various industries.

Ningbo Hansheng Machinery Parts Co., Ltd. (Ningbo Yifei Machinery Parts Co., Ltd.) is a specialized Casting Bucket Tooth And Accessory manufacturer serving global construction, mining and agricultural equipment operators. We supply bucket teeth, adapters, pins, retainers, side cutters and bucket protectors through investment casting, sand casting and forging processes. Our range covers standard and rock-grade teeth for excavators, loaders, bulldozers, backhoes and skid steer machines, with direct cross-reference to Caterpillar, Komatsu, Daewoo, Hyundai, Hitachi, Volvo and Kobelco systems.
Founded in 2003 and operating from a 5,000 m² facility in Ningbo, China, we maintain an ISO 9001:2000 quality system. Our engineering team works from customer drawings or OEM part numbers to produce castings that meet or exceed original specifications. Most of our production is exported to the United States, the United Kingdom, Spain, Germany, France and other European markets.
We manufacture the following categories of bucket tooth and accessory components. Each type is designed for a specific wear environment and machine class.
| Component | Typical application | Process options | Material examples |
|---|---|---|---|
| Standard bucket teeth | General earthmoving, soft soil, light construction | Investment casting, sand casting | Alloy steel, carbon steel |
| Rock chisel teeth | Hard rock, mining, frozen ground, demolition | Investment casting, forging | 30CrMnSi, high-manganese steel |
| Bucket adapters | Mounting interface between bucket and tooth | Investment casting, sand casting | Alloy steel with Mo/Ni microalloying |
| Forged bucket teeth | Severe rock digging, ice-breaking, mine-digging | Closed-die forging | 30CrMnSi |
| Pins, retainers, locks | Tooth-to-adapter retention | Machining from bar stock or casting | Carbon steel, heat-treated alloy steel |
| Side cutters, bucket protectors | Wear protection for bucket edges | Investment casting | Alloy steel |
Our bucket teeth and adapters are engineered for wear resistance and impact toughness. For investment-cast parts, we target a hardness of approximately 48 HRC with impact energy above 15 J at room temperature. The chemical composition is controlled with C, Si, Mn, Cr and Al as base alloy elements; we add Mo and Ni when the application demands higher wear life in abrasive rock or quartz-bearing soil.
Forged bucket teeth in 30CrMnSi deliver improved mechanical properties compared to cast equivalents, making them suitable for continuous rock digging, ice-breaking and mine-digging operations. The forging process refines the grain structure and eliminates internal porosity, which directly translates to longer service intervals and reduced replacement cost.
Bucket capacity compatibility ranges from 0.1 m³ to 20 m³, covering compact track loaders through large mining excavators. We supply teeth for J250 through J700 series adapters, with individual tooth weights from 3.0 kg to 54 kg.
We maintain a catalog of standard bucket tooth specifications for Caterpillar, Komatsu, Daewoo, Hyundai, Hitachi, Volvo and Kobelco machines. For each reference we can supply the correct tooth profile, adapter geometry, pin size and retainer type. Our proposal is based on the following project information:
We produce bucket teeth and accessories using four core processes: investment casting (lost wax), sand casting, die casting and closed-die forging. Each process is selected based on part complexity, quantity, material and required mechanical properties. Our workshop is equipped with wax injection machines, CNC machining centers, heat treatment furnaces and digital flame-cutting equipment for HARDOX steel plate.
Quality assurance follows the ISO 9001:2000 standard. All items are identified throughout manufacturing and traceable to the raw material batch. We supply material chemical composition reports with each shipment. Internal and external audits are conducted to maintain system effectiveness.
Bucket teeth are assembled to adapters using a pin, retainer and lock system. We supply the complete retention hardware to ensure secure fitment under impact loading. Regular inspection of tooth wear and pin retention is recommended; replacement intervals depend on material hardness and operating conditions. We stock commonly used teeth, adapters and pins for J250–J700 series to support rapid replenishment.

What materials do you use for bucket teeth?
We use alloy steel with controlled C, Si, Mn, Cr and Al content. For high-wear applications we add Mo and Ni. Forged teeth are made from 30CrMnSi. Hardness is typically 48 HRC with impact energy above 15 J.
Can you match OEM bucket tooth dimensions?
Yes. We manufacture to meet or exceed OEM specifications for Caterpillar, Komatsu, Daewoo, Hyundai, Hitachi, Volvo and Kobelco. We can work from your OEM part number or a physical sample.
What is the difference between cast and forged bucket teeth?
Forged teeth have finer grain structure and higher mechanical strength, making them more wear-resistant in severe rock digging. Cast teeth are more economical for general earthmoving and are available in complex adapter geometries.
Do you supply the pins and retainers with the teeth?
Yes. We supply complete retention hardware including pins, retainers and locks to match the tooth and adapter system.
What is your typical lead time for custom bucket teeth?
Lead time depends on quantity, process and material availability. Standard parts from our catalog can ship within 2–3 weeks. Custom castings typically require 4–6 weeks including tooling and first-article inspection.
Do you provide material certificates?
Yes. We supply material chemical composition reports and, upon request, mechanical test results for each production lot.
Our portfolio also includes NEXT: Bucket Teeth of Bucket Adapters (V23), NEXT: Forging Bucket Tooth for Cat, Custom Casting Bucket Adapters for Bucket Teeth Factory for applications with different operating ranges, interfaces or integration requirements.
