About Shijiazhuang Capt Power Transmission Machinery Co., Ltd. - Machined Components Supplier in China

Based in China, Shijiazhuang Capt Power Transmission Machinery Co., Ltd. lists eleven active product lines across machined components and related mechanical parts. The catalogue includes timing pulleys, poly‑V pulleys, gear racks, worm gears and shafts, variable‑pitch pulleys, DIN‑standard sprockets, couplings, gears, DIN‑standard taper bushings, keyless locks and valve actuators. Several items fall under HS Chapter 84, notably HS 8483.40 for gear racks, worm gears, sprockets and gears, and HS 8483.60 for taper bushings, while the locks are classified under HS 8301.40 and the valve actuators under HS 8481.80. Materials specified range from carbon steel C45 and alloy steel 20MnCr5 to hardened steel, bronze, cast iron HT250, zinc alloy and aluminum alloy housings. The supplier’s top categories include machined components, automobile gears, shafts & clutches, automobile spare parts, industrial couplings, bearings, door locks and electronic actuators.

The product list reflects standard mechanical transmission elements used in automotive and industrial applications. Timing and poly‑V pulleys are typically supplied in sizes from 20 mm to 200 mm pitch diameter, with tooth profiles conforming to ISO 1328. Gear racks and gears are commonly produced in case‑hardened alloy or carbon steel to meet surface hardness of 55‑60 HRC. Worm gear assemblies combine hardened steel shafts with bronze wheels to achieve high torque reduction ratios. DIN‑standard sprockets and taper bushings follow DIN 7925 and DIN 748 dimensions, respectively. Keyless locks are fabricated from zinc alloy with steel reinforcement, and valve actuators integrate aluminum alloy housings with stainless steel fasteners for corrosion resistance.

Product Range and Specialties of Shijiazhuang Capt Power Transmission Machinery Co., Ltd.

Shijiazhuang Capt’s catalogue covers eleven mechanical transmission products, each tied to specific HS codes and material specifications. Timing and poly‑V pulleys are plain steel components, while gear racks, worm gears, DIN‑standard sprockets and gears are classified under HS 8483.40 and are typically manufactured from carbon steel C45, alloy steel 20MnCr5 or case‑hardened alloys to achieve hardness levels of 55‑60 HRC. The worm gear shafts are hardened steel paired with bronze wheels, a common combination for wear resistance. European DIN‑standard taper bushings (HS 8483.60) are cast from HT250 iron or carbon steel, matching DIN 748 tolerances. Keyless locks (HS 8301.40) use zinc‑alloy bodies with steel components, and valve actuators (HS 8481.80) combine aluminum alloy housings with carbon steel gears and stainless steel fasteners, reflecting typical material choices for durability and corrosion protection.

Trade and Export Information - Shijiazhuang Capt Power Transmission Machinery Co., Ltd.

China is a major global exporter of mechanical transmission parts, with Europe, North America and Southeast Asia representing the largest demand clusters. HS 8483.* codes for gears, racks and sprockets are routinely inspected for compliance with material standards such as EN 10204 test certificates, and customs authorities often require documentation of heat‑treatment processes. Buyers of brake‑type components and industrial couplings frequently request ISO 9001 certification and, for European destinations, CE marking or RoHS declarations to satisfy safety and environmental regulations. Standard shipping practices involve loading the wooden crates or reinforced boxes into 20‑ft or 40‑ft containers, using Incoterms such as FOB or CIF, and providing a commercial invoice, packing list, certificate of origin and material test reports for customs clearance.

Sourcing from Shijiazhuang Capt Power Transmission Machinery Co., Ltd. - Buyer Guidance

When sourcing from Shijiazhuang Capt, request material test reports that confirm chemical composition, hardness (typically 55‑60 HRC for hardened parts) and dimensional tolerance according to ISO 2768. Verify whether the supplier holds ISO 9001 or other quality‑management certificates; if not, obtain a recent factory audit report. Clarify the required finish (e.g., black‑oxide, zinc‑plating) and ask for a sample batch to assess surface quality and tooth profile accuracy before confirming large volumes. Confirm packaging details, container loading plans and the Incoterm to be used, and ensure that the commercial invoice lists the correct HS codes for each product line.
