Starting from the needs: How to choose the bucket teeth that really suit you?

1. Identify the Operation Scenario: Working Conditions Determine Bucket Tooth Type

Different construction environments have significantly different requirements for bucket tooth wear resistance, strength, and structure, which is the core consideration for selection.

Earthmoving: For soft soils such as clay and loam, standard bucket teeth with medium wear resistance are recommended. These teeth have sharp cutting edges, reduce penetration resistance, increase excavation speed, and are reasonably priced, making them suitable for long-term, continuous operation.

Rockmoving: For hard rock such as granite and limestone, wear-resistant bucket teeth made of high-chromium cast iron or bimetallic composite materials are essential. Their reinforced cutting edges provide strong impact resistance and reduce the risk of breakage. For example, our "Rock King" series bucket teeth offer a service life exceeding 30% longer than standard bucket teeth in mining operations.

Mixed Working Conditions: For construction sites with a variety of materials, such as soil, rock, and sand and gravel, universal bucket teeth are recommended. These teeth offer a balance of sharpness and wear resistance, and their optimized cutting angle design allows them to adapt to alternating operations in complex environments.

2. Matching Equipment Model: Dimensions and Power Must Be Precisely Matched

Bucket teeth are not universal components and must be strictly matched to the excavator and loader models.

Dimensional Compatibility: The length, width, and mounting hole location of the bucket teeth must perfectly match the bucket. Too short will cause increased wear on the bucket body, while too long may increase operating resistance and even cause mechanical failure. Please refer to the bucket tooth specifications in the equipment manual, or provide your bucket model to our technical team for a customized matching solution.

Power Matching: Using heavy-duty bucket teeth for small equipment (such as excavators under 20 tons) will increase fuel consumption due to excessive load. Using light-duty bucket teeth for large equipment can lead to breakage due to insufficient strength. It is recommended to select bucket teeth with the appropriate strength level based on the equipment's rated power. For example, a 30-ton excavator should be equipped with reinforced bucket teeth with a tensile strength of 800 MPa or higher.

3. Focus on Material and Craftsmanship: Key to Durability

The service life of bucket teeth is primarily determined by the material and manufacturing process. Key considerations when selecting bucket teeth include:

Material Selection: Ordinary low-carbon steel bucket teeth are only suitable for light duty applications. Medium- and high-carbon steels significantly improve wear resistance after quenching. Bimetallic bucket teeth, a composite of high-chromium cast iron and steel, combine hardness (HRC ≥ 60) and toughness, making them the preferred choice for tough working conditions.

Process Details: High-quality bucket teeth are manufactured using a one-piece forging or precision casting process to ensure they are free of internal defects such as pores and cracks. For example, our bucket teeth undergo salt spray and impact testing and feature a multi-layer wear-resistant coating to further extend their service life.

4. Comprehensive Cost Calculation: Avoid the Mistake of "Only Focusing on Unit Price"

When selecting bucket teeth, consider more than just the purchase price; consider the "comprehensive cost."

-Lifecycle Cost: While the unit price of a pair of wear-resistant bucket teeth may be higher, the replacement frequency is lower, resulting in a lower hourly operating cost. For example, a customer used to replace standard bucket teeth three times a month. After switching to our wear-resistant bucket teeth, they only need to replace them once a month, saving over 20,000 yuan annually.

-Maintenance Costs: Inferior bucket teeth are prone to loosening and breaking, potentially causing damage to the bucket, pins, and other components, increasing repair costs. We recommend choosing bucket teeth with anti-loosening features to reduce routine maintenance time.
