X156H Bucket Tooth Adapter 156-75 for Mini Excavators Heavy-Duty Machinery Accessories

1. Core Specifications and Features

• Series Type: 156 Series Bucket Tooth (Parabolic System )
• Tooth Tip Model (X156H): The X156H designation typically represents a reinforced or standard-duty bucket tooth within the series, specifically engineered for heavy-duty or high-penetration applications. The X156 series also includes various other styles—such as Long Teeth (X156L) and Single Tiger Teeth (X156T)—all of which are secured via a pin retention system.
• Adapter Model (156-75): This is a standard weld-on adapter; the numerical suffix typically indicates the specific bucket lip thickness it is designed to accommodate (e.g., 0.75 inches, or approximately 19 mm).
• Compatibility: Compatible with the vast majority of small to medium-sized construction machinery equipment currently on the market, including brands such as CAT, JCB, Bobcat, Takeuchi, John Deere, and Komatsu.

2. Manufacturing Process: Precision Casting Combined with Heat Treatment

1. Precision Casting (Primary Process): Primarily employs the Investment Casting method. This process enables the production of bucket teeth with complex geometries while ensuring precise dimensional accuracy and a smooth surface finish.
2. Heat Treatment Strengthening (Quenching + Tempering): Following the casting stage, the components undergo a rigorous heat treatment process controlled by precise heating and cooling curves. This is a critical step in determining the bucket tooth’s service life, as it imparts a “tough core with a hard exterior”—effectively preventing fracture or deformation during high-intensity excavation operations.

3. Structural Design: Heavy-Duty and Self-Sharpening Features

• Heavy-Duty Design: Compared to standard-duty bucket teeth, the X156H features increased material thickness in high-wear areas, enabling it to withstand more severe penetration impacts.
• Mechanical Analysis: Leverages Computer-Aided Design (CAD) and Finite Element Analysis (FEA) to optimize stress distribution, thereby ensuring that the component does not experience premature failure when subjected to high bending moments.

4. Powerful Excavation Performance

The X156H bucket tooth is crafted from low-carbon alloy steel and feature a robust structural design, ensuring exceptionally high operational efficiency even under severe working conditions—including hard soil, rocky terrain, gravel, and sandy environments. Furthermore, they offer an exceptionally long service life during continuous operation.

5. Simple Installation—Fast and Efficient

Designed with user convenience in mind, the installation process for this excavator X156H bucket tooth has been streamlined. It utilizes standard 156-series pins (such as the P156/156LPN pin) for secure fastening, allowing for the quick replacement of worn tips directly at the job site. This ensures rapid equipment recovery and significantly boosts overall operational efficiency.

6. X156H Bucket Tooth Adapter 156-75 Applications

Thanks to their compact and wear-resistant design, the 156-series bucket teeth and adapters are ideally suited for a wide range of operational environments—including applications in agriculture, construction, mining, and general industry. Specific use cases include small-scale earthmoving and light excavation, landscaping and site grading, excavation in soft to medium-hard soils, as well as agricultural land maintenance and material loading. These components offer reliable compatibility with small excavators and other compatible machinery.
