Import Heavy Duty Welded Hydraulic Cylinder — Buy in wholesale FOB from Supplier in China

The Heavy Duty Welded Hydraulic Cylinder supplied by Hengyang Zk Industrial Co., Ltd. of China is a robust linear actuator designed for high‑force applications. It is offered with rod diameters ranging from 30 mm to 200 mm and bore diameters from 60 mm to 280 mm. Stroke length can be customised up to 3 025 mm, and the cylinder is rated for pressures as high as 60 MPa. The design tolerates operating temperatures between - 80 °C and 120 °C, matching demanding industrial environments.

The cylinders are fabricated by welding steel tubes, a common practice for heavy‑duty hydraulic components that balances strength and manufacturability. In the sector, carbon steel such as ASTM A36 or equivalent forged grades are typically used, providing adequate yield strength for the stated pressure rating. Standard surface finishes include black oxide or zinc plating to improve corrosion resistance, while double‑acting piston seals of nitrile rubber are the norm. Suppliers often offer optional hard‑chrome lining on the bore for extended wear life; Hengyang Zk notes the ability to adapt the finish on request.

These cylinders are suited to construction equipment, mining machinery, and large‑scale material handling systems where reliable force transmission is essential. Importers such as OEMs of excavators, bulk material conveyors, and hydraulic press manufacturers commonly source this type of actuator. The supplier indicates that custom models can be manufactured according to buyer specifications, and bulk orders are packed in wooden crates for safe transit. Buyers should confirm the desired Incoterm, payment schedule and any required inspection protocol directly with the supplier before finalising the contract.

Hengyang Zk Industrial Co., Ltd. is located in the Dingfeng International Building on Renming Road, Shigu District, Hengyang, Hunan Province, China, postal code 421002. The company is listed with a harbor trust tier, indicating a basic level of verification on the platform. Current response metrics show a response rate of 0 % and an average response time of 0 hours, suggesting that communication may need proactive follow‑up.

The supplier’s catalogue highlights the ability to produce welded hydraulic cylinders across a broad range of dimensions, and it invites buyers to provide non‑standard models for custom manufacturing. No specific certifications, minimum order quantities or lead‑time figures are published, so interested parties should request these details directly. The company does not disclose additional corporate history or client references in the public profile.
