Import Couplings — Buy in Bulk from Supplier in China

These couplings are precision-cast components designed for mechanical power transmission, typically used to connect rotating shafts in industrial machinery. The listing confirms they are manufactured from high-grade materials to withstand heavy loads, with available sizes tailored to standard industrial shaft diameters. No exact dimensions or material grades are specified, but the product is intended for applications requiring reliable torque transfer under dynamic conditions.

Typical couplings in this category are cast from ductile iron or carbon steel, with surface finishes ranging from bare metal to anti-corrosion coatings. Standard tolerances for bore diameters are usually ±0.05 mm, and keyway dimensions follow ISO 13344 or DIN 6885. These are not precision-machined components but are engineered for durability in high-vibration environments, commonly used in pumps, conveyors, and gearboxes where alignment flexibility is needed.

Buyers in manufacturing, construction equipment, and agricultural machinery sourcing these couplings typically require batch quantities for replacement or OEM integration. Trade terms include FOB and CIF, with payment methods accepted as L/C or T/T. Packaging is standard industrial, likely in wooden crates or corrugated cartons, depending on order size. Lead time and minimum order quantity are not stated and must be confirmed directly with the supplier.

Shinwa International Trading Co., Ltd. is based in Tianjin, China, with a registered address at 9F, Building B, Future Plaza, No.103 Weididao. The supplier is classified as imported and holds a harbor trust tier, indicating verified export activity. No details are provided on production capacity, years in operation, or internal quality control processes. The listing does not confirm manufacturing capability, suggesting the supplier acts as an exporter or distributor.

There is no information on workforce size, revenue, certifications, or client list. The supplier's response rate and average response time are recorded as zero, indicating no recent buyer communication on record. The absence of verified production claims means buyers must treat this as a trading entity sourcing couplings from third-party manufacturers in China. All technical claims must be confirmed directly before order placement.
