Leading KOMATSU Excavators Bucket Tooth and Adapters Manufacturer in China

From a physical properties perspective, two key indicators for bucket teeth are: first, hardness; second, impact toughness.

Hardness partially indicates wear resistance, but wear resistance isn’t solely determined by hardness.

For instance, factors like carbide content, wear-resistant components, and wear-resistant microstructure also significantly impact wear resistance.

Secondly, impact toughness ensures the product doesn’t fail prematurely during use. Failure includes scenarios like fracture or complete wear. In harsh winter environments like Russia or Canada, we conduct impact performance tests at -40°C. This ensures bucket teeth remain functional during use. While wear resistance is crucial, a broken bucket teeth is far less problematic than a broken adapter.

If a bucket teeth breaks, we simply remove the pin and replace it with a new teeth. However, a broken adapter is the most troublesome scenario.

A common physical test I perform is the friction and wear test. We take a small sample from the product, place it in the machine, and simulate actual usage conditions with abrasives like quartz sand. After grinding, we weigh the sample for comparison. For sampling, it’s recommended to take a core sample and test its hardness and impact resistance. Surface hardness tests are often inaccurate. If surface hardness is high while core hardness remains low, external wear may appear satisfactory initially, but core degradation accelerates rapidly. Therefore, when selecting bucket teeth, never judge solely by appearance. Always evaluate both properties: hardness and impact toughness.

Some bucket teeth exhibit impact-heat resistance exceeding 17, making them virtually unbreakable. Higher impact performance significantly reduces fracture probability.
