Welded Clevis Type Cylinders WC-3000PSI: Female-Clevis Hydraulic Power for Pivot-Mount Equipment

Female-clevis mounted 3000 PSI welded hydraulic cylinders engineered for pivot-load applications on trailers, implements, and lift rigs.

WC3015XX - WC3050XX  |  Bore 1.5" to 5"  |  Stroke 4" to 48"

The welded clevis hydraulic cylinder WC-3000PSI is the pivot-friendly sibling of our welded tee range, designed for OEMs and rebuilders whose brackets expect a female-clevis rod eye at both ends. Every welded clevis hydraulic cylinder in the WC-3000PSI family is rated to a repeatable 3000 PSI working pressure across bore sizes from 1.5" to 5", with stroke lengths from 4" right up to 48". The double-yoke female clevis mounting transfers pin load cleanly through the weld footprint, which is why the WC-3000PSI welded cylinder has become a standard fitment on tilt-deck trailers, implement hitches, tractor three-point linkages, and articulated tool carriers.

EVER POWER has shipped the welded clevis hydraulic cylinder into more than thirty export markets, and the cumulative field feedback has shaped every tolerance you now see on the datasheet — from the 1/8" stroke tolerance band to the chrome-plating thickness on the rod. A WC-3000PSI welded cylinder coming off our Hangzhou line today carries the same pin-to-pin centerline accuracy the original bracket was designed for, so your assembly line does not have to fight fitment issues when replacement volumes ship in.

Why Choose EVER POWER WC-3000PSI?

Specifying a welded clevis hydraulic cylinder means weighing mounting compliance, rod-end geometry, and long-term fatigue life together. The WC-3000PSI welded cylinder has been refined across twenty-plus production seasons so each of those variables lands on the favourable side. What follows are the six concrete engineering choices that keep buyers reordering the welded clevis hydraulic cylinder quarter after quarter.

Working Principle & Construction

A welded clevis hydraulic cylinder works on the double-acting principle shared by most heavy-duty linear actuators — pressurised fluid enters the cap-end port to extend the rod, or the rod-end port to retract. What separates the WC-3000PSI welded cylinder from a tie-rod build is the fact that both end caps are fully welded to the barrel and both mounting yokes are welded in turn to those end caps. There are no fasteners in the primary load path, so the welded clevis hydraulic cylinder tolerates shock-loaded pivot service without the creep or loosening that defeats a bolted assembly.

Material selection is driven by the application environment. Barrels are cold-drawn seamless steel tube, honed to a mirror finish on the ID. Rods are induction-hardened carbon steel, then hard chromed. End caps and clevis yokes are machined from 45# forged steel and welded with qualified procedure specs. Seal stacks default to Nitrile with a polyurethane primary rod seal for extended abrasion resistance. Every WC-3000PSI welded cylinder carries an operating temperature window of −30°C to +100°C as standard, with Viton and fluorosilicone compounds available for hot-fluid applications.

Barrel wall thickness on every welded clevis hydraulic cylinder is calculated to deliver a proof-pressure margin of at least 1.5× over the rated 3000 PSI. The WC-3000PSI welded cylinder ships from our factory with rod-end anti-corrosion plugs installed in both ports to prevent contamination during ocean freight. Rod seal groove geometry follows ISO 5597 proportions so your shop already has the replacement kits that fit.

Typical Applications of the WC-3000PSI

A welded clevis hydraulic cylinder lives or dies on real-world pivot duty, not on bench tests. The WC-3000PSI range has been installed on tilt-deck car haulers shuttling vehicles across American ports, on three-point-hitch implements behind European tractors, on boom articulations on Latin American log loaders, and on hook-lift bodies for Chinese waste-management operators. In every one of those fields, the welded clevis hydraulic cylinder has to swing, retract, and hold under load cycle after cycle. The WC-3000PSI welded cylinder handles it because the pivot geometry was optimised by the people who actually service the machines downstream.

What Our Customers Say

Inside Our Hangzhou Factory

EVER POWER Hydraulic Machinery operates an integrated production facility in Binjiang District of Hangzhou, Zhejiang Province, China. The plant covers hydraulic cylinder design, CNC machining, robotic welding, rod chroming, assembly, and full QC testing under one roof. Our Hangzhou engineering team has been designing the welded clevis hydraulic cylinder line since 2002, with current annual capacity of 120,000 cylinders across the full catalog including the WC-3000PSI platform.

Our quality system is ISO 9001:2015 certified. Every welded clevis hydraulic cylinder that leaves the production floor has a traceable serial number linked to raw material certificates, weld records, pressure test data, and final dimensional inspection. We hold CE documentation for European export, and routinely supply buyers in the United States, Canada, Australia, Germany, France, Brazil, Mexico, and Southeast Asia. Third-party inspection by SGS, BV, TUV, or the buyer's own engineer is welcome at any stage.

Quality & Testing Program

Every WC-3000PSI undergoes a multi-stage test program before leaving Hangzhou. Raw tubing is checked for OD/ID dimensional tolerance and straightness on receipt. After honing, each barrel is measured for bore finish (target 0.4-0.8 μm Ra) and cylindricity. Chrome-plated rods are measured for plating thickness with an eddy current gauge and inspected for surface pits under 10x magnification. The final assembled welded clevis hydraulic cylinder is pneumatically leak-tested at working pressure, and a sampling ratio is hydraulically proof-tested to 1.5x rated pressure.

Our 10-Step Production Flow

Sourcing a WC-3000PSI Directly from Hangzhou, China

Zhejiang Province is a key hub of Chinese hydraulic cylinder manufacturing, and our Hangzhou facility sits at the center of that cluster. We ship directly from Hangzhou, China to Ningbo Port, and from there to any global seaport on weekly sailings. The proximity of our factory to Ningbo Port gives buyers a clean logistics corridor with container loading often inside seven working days of final test sign-off.

Overseas buyers reach our production floor through Ningbo Port for sea freight, or Hangzhou Xiaoshan International Airport for air samples. Any buyer who needs to receive a WC-3000PSI in Shanghai, Guangzhou, Chongqing, or any industrial hub across China can expect inland dispatch within three working days of approval thanks to the Hangzhou-Ningbo freight corridor and Yangtze River Delta logistics network.

Order Terms & Payment

Standard payment terms are 30% TT deposit with balance against copy of bill of lading, or LC at sight for orders above USD 50,000. Trade Assurance orders through Alibaba are accepted up to USD 100,000. We support FOB Ningbo, CIF to most major ports, and DDP for select European and North American destinations. All welded clevis hydraulic cylinder shipments leave our Hangzhou plant in fumigated wood crates with port-protection caps on ports and desiccant inside the cylinder bore.
