Trailer Parts King Pin 2 Inch Welded King Pin
The 2‑inch welded king pin is a critical steering component for commercial trailers and semi‑trailers. It is manufactured from 40CrV alloy steel, a high‑strength alloy, and also offered in 45# carbon steel, both meeting heavy‑duty load requirements. The pin has a nominal diameter of 2 inches and a total weight of approximately 8 kg per unit. It is rated for a maximum payload of 50 tonnes, aligning with industry standards for high‑capacity trailer assemblies.
Typical king pins are heat‑treated through quench and temper to achieve tensile strengths above 800 MPa, a practice the supplier follows for the 40CrV grade. The welded construction eliminates the need for separate bushings and provides a rigid connection between the trailer frame and steering assembly. Standard dimensions include a 2 inch shank length of around 300 mm and a threaded end conforming to M30×1.5 mm pitch, which is common across European and North American trailer fleets. While the listing does not specify surface coating, a hot‑dip galvanised finish is typical for corrosion protection in this application.
Fleet operators, aftermarket distributors and trailer manufacturers purchase this component for replacement or new‑build projects. The supplier ships the pins from Shandong, China and can provide bulk quantities, but exact MOQ, lead time and Incoterms must be confirmed with the seller. Payment is usually arranged via T/T after pro‑forma invoice, and buyers should request material test certificates to verify compliance with load specifications.

Sourcing Trailer Parts King Pin 2 Inch Welded King Pin from Jining Bst Machinery Co., Ltd - China Import Guide
Importers should first request a material test certificate confirming the 40CrV or 45# steel grade, as well as a dimensional drawing showing the 2‑inch diameter, thread pitch and shank length. Verifying the heat‑treatment report and corrosion‑resistance coating will help ensure the king pin meets the required load and safety standards for your fleet.
Logistics for these components typically involve container consolidation at the port of Qingdao or Tianjin. Buyers need to agree on Incoterms such as FOB Qingdao or CIF destination, and clarify expected lead times, as these are not published in the listing. Payment is commonly arranged by T/T against a pro‑forma invoice, with the option of a letter of credit for larger volumes.
Quality assurance should include a third‑party inspection at the loading port, checking weld integrity, thread accuracy and surface finish. Request a certificate of compliance and a mill test report before the goods are released. Maintaining records of these documents will facilitate customs clearance and future supplier evaluations.
