Custom OEM hydraulic cylinders for rolling mills, continuous casting, forging presses, and underground mining operations in Russia and CIS countries — ISO 9001:2015 · FOB Shanghai · 24 h quote
Wuxi Hengshui Machinery Co., Ltd. has extensive experience supplying custom hydraulic cylinders to Russian and CIS steel mills, mining operators, oil & gas facilities, and OEM machine builders. Russia's massive metallurgical industry — home to the world's largest steel producers including NLMK, Severstal, MMK, and Evraz — requires a continuous supply of large-bore, high-pressure hydraulic cylinders for rolling mills, continuous casting machines, ladle handling systems, and converter tilting drives.
Our rolling mill hydraulic cylinders are manufactured with bore diameters from Ø80 mm to Ø800 mm, working pressures to 350 bar, and FKM seals rated for continuous operation at low ambient temperatures (down to –40°C with appropriate hydraulic fluid selection). Chrome-plated alloy steel rods ground to h6 tolerance ensure precise control in automatic gauge control (AGC) systems. We provide EN 10204 3.1 material certificates and can supply GOST-compliant documentation on request.
For Russian mining operations — including longwall coal mining in the Kuznetsk Basin and underground metal ore mining in the Urals — Hengshui manufactures powered roof support (PRS) leg cylinders, hydraulic props, and drill rig cylinders with heavy-duty dust and water exclusion sealing systems. High-cycle duty with long service intervals between seal replacements is a design priority.
We provide a complete commercial export package for all shipments to Russia: Commercial Invoice, Packing List, Bill of Lading, Certificate of Origin (Form A or Form ST-1 for EAEU preference), Material Test Certificates (mill certificates), Pressure Test Reports, and Dimensional Inspection Reports. For projects requiring third-party inspection (SGS, BV, Intertek), we coordinate with your nominated inspection body at our Wuxi factory.
We accept payment in USD, EUR, and CNY. Standard terms for new customers are 30% T/T deposit with 70% against Bill of Lading. For established Russian customers, we can discuss extended terms. Shipment is via FOB Shanghai or Tianjin Port. Transit time to Vladivostok is approximately 8–12 days; to St. Petersburg via Baltic is 28–38 days. We work with established freight forwarders experienced in Russia CIS routing and customs documentation.
A Russian flat products rolling mill operator required 24 custom hydraulic cylinders for a cold rolling mill AGC (Automatic Gauge Control) system — bore Ø200 mm, stroke 300 mm, 315 bar working pressure, FKM seals, with position transducer integration. Hengshui delivered the full set within 35 working days, achieving ±0.05 mm position accuracy in the customer's AGC control loop after commissioning.
