Excavator Bucket Teeth 389-5743

Excavator bucket teeth are a critical wear-resistant component at the front end of an excavator bucket. Their primary function is to directly cut into and excavate materials while protecting the bucket structure. They typically feature a modular design consisting of a tooth adapter (fixed to the bucket lip) and a removable tooth tip, connected by a pin. When the tooth tip wears out, the entire bucket can be replaced; only the tooth tip itself can be replaced. Directly excavating, the tooth acts as the primary point of contact between the bucket and the material, performing the primary cutting and excavation tasks. Protective devices reduce wear on the bucket body through wear itself, extending bucket life. The tapered design improves efficiency, increasing operating pressure for easier digging and providing a reference point for precise operation. The tooth tip also provides a cushioning effect, dissipating impact forces when digging in hard materials and protecting the equipment structure.
