Bucket Teeth 7T-3402 7T3402 Long Tip For Excavator E320C E324D E330C E330D

The bucket teeth are the only components that directly contact the working device with the working medium (soil, rock, gravel, etc.). Their tips bear almost all the cutting, crushing, and stripping loads. Their designed geometry (such as angles and surfaces) directly determines the smoothness, resistance, and filling efficiency of the digging cut. They are the forefront actuator that converts the excavator's hydraulic power into effective digging work, fundamentally impacting the overall machine's operating efficiency and fuel consumption.

The core design philosophy of the bucket teeth is "sacrificial protection." Cast from high-strength alloy steel and undergoing special heat treatment, they are designed to be the first component to fail under severe wear and impact. By periodically replacing the relatively inexpensive bucket teeth, the much more expensive bucket lip, side edges, and other main structural components are protected from direct damage, greatly extending the overall service life of the bucket and representing a key strategy for reducing long-term operating costs.

Bucket teeth utilize standardized interfaces (such as snap-fit ​​connections), exhibiting strong modularity. Different models of bucket teeth can be quickly interchanged within the same bucket to adapt to diverse working conditions: for example, long, pointed teeth are used for loosening materials to improve insertion efficiency, short, wide teeth are used for rock breaking to improve impact resistance and wear resistance, and flat teeth are used for fine leveling operations. This specialized design gives a single excavator a wider range of working condition adaptability.

Bucket teeth are a concentrated embodiment of materials engineering. They employ special alloy formulations (such as high-carbon, high-manganese steel) and undergo processes such as water toughening treatment, giving them excellent comprehensive performance: high surface hardness to resist abrasive wear and high core toughness to absorb impact and prevent fracture. Their wear morphology (such as self-sharpening characteristics) is also carefully designed to maintain a relatively sharp cutting edge within a certain wear cycle.
