Import Bucket Adapter/1u3352/1u3302 — Buy in Bulk from Supplier in China

The 1U3352 and 1U3302 bucket adapters from Ningbo Tuoxing Precision Casting Co., Ltd. are ground engaging tools (GET) manufactured in Ningbo, China, for attachment to Caterpillar excavator and loader buckets. These adapters serve as the interface between the bucket lip and replaceable teeth, transferring digging forces while allowing rapid tooth replacement. The source description identifies compatibility with Cat models 225, 215, 230, 325, 330, and E200 series machines. The adapters are produced through precision casting, with a stated monthly production capacity of 1,800 tons across the full GET product range.

Material specification is critical for adapter performance in abrasive earthmoving applications. The supplier provides impact test data at 20°C and -40°C for three material categories: carbon steel, alloy steel, and special alloy, all with target hardness 47-52 HRC. Impact values range from 17J (carbon steel, 20°C) to 22J (special alloy, 20°C), with corresponding sub-zero values of 11J to 14J at -40°C. These figures suggest through-hardened alloy steels with toughness retention for cold-climate operation, though the exact alloy grades (e.g., AISI 4140, 4340, or proprietary equivalents) are not disclosed. Heat treatment protocol (quench and temper, austempering) and weldability characteristics should be confirmed with the supplier.

Primary buyers include construction equipment dealers, mining contractors, and aftermarket parts distributors who require OEM-compatible or custom GET for fleet maintenance. The adapters suit high-wear applications in rock excavation, trenching, and material handling where tooth change frequency justifies a robust adapter system. Trade terms are not specified in the source; buyers must confirm incoterms, packaging specification (wooden or iron carton options mentioned), HS code 84314990 applicability for their import regime, and any required certificates of origin or material test reports. The supplier holds ISO 9001 and TS 16949:2009 certifications according to the listing data.

Ningbo Tuoxing Precision Casting Co., Ltd. is located at #82, Fengheng Road, Baidu, Xiwu, Ningbo 315558, China. The company operates within the precision casting sector and has specialised in ground engaging tools and investment castings since 2003, according to its self-reported history. The supplier holds ISO 9001 and TS 16949:2009 quality management system certifications and reports a production capacity of 1,800 tons per month. The source profile does not state employee headcount, annual revenue, factory floor area, or specific equipment list (induction furnaces, shell-making lines, heat treatment facilities).

The supplier's product range extends beyond bucket adapters to include bucket teeth, cutting edges, tips, side cutters, end bits, ripper shanks, shank guards, and scarifier shanks. The listing claims OEM manufacturing status and compatibility with multiple earthmoving equipment brands including Caterpillar, Komatsu, Hitachi, Kobelco, JCB, Hyundai, Daewoo, Case, Volvo, Hensley, H&L, Bobcat, Liebherr, Kawasaki, Fiat, and Bofors. The response rate is 0.00% with zero average response hours on the platform, so direct communication channels (email, telephone, trade fair meeting) are likely more effective for initial enquiry. Buyers should verify the claimed certifications directly with the certification body or through supplier audit.
