The Drive sprocket rim 3/8-7 is a machined component designed to transmit power in equipment that uses a 3/8‑7 tooth profile. It is manufactured in China by Wenzhou Chaohong Machinery Co., Ltd and matches the 3/8‑7 specification while also fitting 404‑7 and 3/8‑8 rims. Precision machining provides a true fit for the designated tooth count, reducing backlash in gear drives. The rim is fabricated from a durable steel alloy intended to resist industrial stress and fatigue.
In the industry such rims are commonly produced from heat‑treated carbon steel to a grade equivalent to ASTM A29, giving a typical hardness of 55‑60 HRC after quenching and tempering. The standard tooth pitch for a 3/8‑7 rim is 7 teeth per inch, and the rim width is typically 0.5 inches, resulting in an approximate weight of 1.2 kg per unit. Surface finish is usually Ra 0.8 µm to facilitate smooth chain engagement. These typical characteristics help ensure reliable operation under continuous load.
The rim is widely used in automotive assembly lines and general manufacturing machinery where reliable chain drive is essential. Buyers such as equipment integrators and OEMs often require bulk shipments, and the supplier offers FOB and L/C terms for export. Because the listing does not disclose a minimum order quantity, interested parties should confirm the MOQ and lead time directly with the supplier. Documentation for export quality is provided on request.

Before placing an order, verify the material grade, hardness, and dimensional tolerances against your equipment requirements. Request the supplier’s material test certificate, hardness report, and a dimensional drawing to confirm the rim will meet the specified performance criteria. Confirm that the rim complies with any relevant industry standards that apply to your machinery.
Clarify the shipping terms, such as FOB or L/C, and ask for an estimated lead time based on the quantity you intend to purchase. Discuss payment schedules, any required deposits, and whether the supplier can arrange container loading at the nearest port in China. Ensure that the incoterm and logistics plan align with your import schedule and cost calculations.
Arrange for a pre‑shipment inspection by a third‑party agency to verify material quality, hardness, and surface finish. Obtain the inspection report and any available export‑quality certificates before the goods leave the factory. Keep records of all documentation, including the commercial invoice, packing list, and certificate of origin, to facilitate customs clearance at the destination port.
