Import Casting Bucket Teeth And Adaptors (Cat330) — Buy in Bulk from Supplier in China

The Casting Bucket Teeth and Adaptors (CAT330) from Ningbo Tuoxing Precision Casting Co., Ltd. are produced in high-manganese steel, typically ASTM A128 Grade C, with a carbon content of 0.35% to 0.55% and manganese content of 11% to 14%. The casting process uses sand molds with controlled cooling to achieve a hardened surface layer. Dimensions conform to Caterpillar CAT330 specifications, with tooth length of 185 mm and root thickness of 22 mm. The adaptors feature a 5-bolt mounting pattern compatible with standard excavator buckets.

These components are designed for abrasive earthmoving applications and harden through work hardening when in contact with rock or gravel. The standard hardness range is 220 to 280 HB on the surface, with a core hardness of 180 to 220 HB to prevent brittle fracture. The casting includes internal ribs for structural integrity and is finished with a light grinding to remove flash. These specifications align with industry norms for heavy-duty excavator attachments used in mining and construction.

The product is used primarily in mining, quarrying, and large-scale earthmoving operations where bucket wear is critical. Buyers include equipment rental firms, mining contractors, and OEM replacement parts distributors. Packaging is in wooden crates or iron frames, with each tooth and adaptor individually wrapped to prevent chipping. Trade terms include FOB Ningbo port. Minimum order quantities are not stated but are typically negotiated based on full container load requirements.
