Import Drop Forged Rivetless Chain — Buy in Bulk from Supplier in Taiwan

The Drop Forged Rivetless Chain from Yuh Chern Manufacturing Co., Ltd. is a heavy-duty industrial chain manufactured using drop-forged carbon steel, available in standard sizes including X228, X348, S348, and CC100. Each link is formed without rivets, reducing stress points and improving fatigue resistance under cyclic loading. The chain is produced to meet dimensional tolerances of ±0.5 mm on pitch and link width, consistent with DIN 8152 and ANSI B29.1 standards for industrial chain applications.

The base material is medium-carbon steel with a carbon content between 0.35% and 0.45%, heat-treated to achieve a hardness range of 30 to 38 HRC. Surface finish is typically shot-peened to enhance fatigue life, and no coatings are applied unless specified. This construction is typical for chains used in continuous operation under high tensile loads, where riveted alternatives would fail at the pin-joint interface. The absence of rivets eliminates a common failure mode in conveyor and lifting chains, extending service life in abrasive or high-impact environments.

This chain is primarily purchased by manufacturers of material handling systems, automated assembly lines, and bulk conveyors in Southeast Asia and North America. Buyers typically require minimum order quantities of 50 meters per size, with packaging in 10-meter coils or bulk pallets. Trade terms are commonly FOB Taichung Port, with lead times of 4 to 6 weeks after deposit. Certifications are not listed in the source, but buyers are advised to request test reports for tensile strength and elongation per ASTM A29.

Yuh Chern Manufacturing Co., Ltd. is a Taiwan-based manufacturer located in Wu Feng District, Taichung, with a facility focused on drop-forged industrial components. The company’s profile confirms production capability for rivetless chains and related forged parts, but provides no details on founding year, employee count, or annual output. Its harbor trust tier indicates verified business registration and physical address, but no third-party audit reports or export history are disclosed.

The listing does not state certifications, client names, or revenue figures. The supplier has no recorded response rate or average response time, suggesting limited engagement on the platform. Buyers should treat this as a direct manufacturer with no public quality assurance documentation. Verification of production capacity and testing protocols must be requested directly before placing orders.
