Finished Bore Sprocket
The Finished Bore Sprocket is a machined steel gear designed to engage 32‑pitch roller chains in power‑transmission systems. It is supplied with a precision‑finished bore that matches standard 30 mm chain‑sprocket dimensions, allowing direct installation on shafts without additional machining. The catalogue lists common tooth counts such as 10, 15, 30 and 72, covering a range of speed reduction ratios. Each sprocket conforms to the ISO 9001:2015 quality management system and the GB/T24001‑2016 environmental standard, indicating consistent manufacturing practices.
Typical material for these sprockets is 30CrMnSiA alloy steel, which provides a hardness of 250 - 300 HB after heat treatment, a level standard for durable chain drives. Surface treatment is usually a black oxide coating that offers corrosion resistance comparable to zinc plating. Dimensional tolerances for tooth profile and bore diameter are generally ±0.05 mm, which aligns with industry norms for high‑precision transmission components. The weight of a 30‑tooth unit is roughly 2.5 kg, a typical figure for steel sprockets of this size.
These sprockets are used in conveyors, agricultural machinery, and industrial equipment where reliable chain engagement is critical. Suppliers offer flexible order quantities and can ship under FOB or CIF terms from ports in Zhejiang province. Each item is packed in a wooden crate with protective padding to prevent denting during sea freight. Importers should confirm the exact MOQ, lead‑time and any required certifications, such as ISO 9001, directly with the supplier.

Sourcing Finished Bore Sprocket from YQ-ChinaTransmissions - China Import Guide
Importers should first confirm that the sprocket’s material grade and heat‑treatment certificates match the specifications required for their equipment. Obtain a detailed product data sheet that includes tooth count, bore size, hardness and surface‑treatment parameters. Verify the supplier’s business registration and the validity of its ISO 9001 and ISO 14001 certificates to ensure compliance with your country’s import regulations.
When arranging shipment, discuss the preferred Incoterm; FOB Ningbo or CIF Shanghai are common departure points for Zhejiang manufacturers. Ask the supplier for an estimated production lead‑time, which typically ranges from three to five weeks for standard orders, and clarify any additional time needed for custom tooth counts or special coatings. Confirm payment terms, such as a 30 % T/T advance with the balance payable against clean documents or via a confirmed L/C.
Plan a pre‑shipment inspection that checks the bore diameter, tooth profile accuracy and coating integrity against the supplied tolerances. Request the hardness test report and a visual inspection report for the black oxide finish. Secure the full set of export documents, including commercial invoice, packing list, certificate of origin and the relevant quality certificates, to avoid customs delays and facilitate smooth clearance.
