An excavator tooth seat, also known as an adapter, is the critical base component that is permanently attached to the excavator's dipper stick or bucket front. Its primary function is to serve as a secure and robust mounting point for replaceable excavator teeth. Manufactured from high-strength, wear-resistant alloy steel through forging and heat treatment, the tooth seat is engineered to withstand extreme digging forces, impacts, and abrasion. It features a locking mechanism to hold the tooth firmly in place during operation. By absorbing and distributing stress, the tooth seat protects the integral bucket structure from wear and damage, significantly extending its service life and reducing long-term maintenance costs. Its reliable performance is essential for maintaining optimal digging efficiency and bucket integrity.
