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.
01 · Double Female Clevis Ends
Both cap and rod terminate in welded female clevis yokes. Pin engagement length is generous, pin size scales from 3/4" through 1-1/2", and the WC-3000PSI welded cylinder drops into symmetric pivot brackets without adapter plates.
02 · Verified 3000 PSI Rating
Each welded clevis hydraulic cylinder holds a retracted working pressure of 3000 PSI. Column loads scale from 5,300 lbs on the 1.5" bore up to 58,900 lbs on the 5" bore. Hydraulic proof-test on sampling is standard.
03 · Hard-Chromed Piston Rod
Induction-hardened rod with 0.03 mm minimum chrome plating resists the scoring that ends the service life of weaker welded clevis cylinders in salt-air and abrasive operating environments.
04 · SAE and NPT Port Options
Standard porting runs SAE-4 through SAE-12 depending on bore. NPT ports are available on request for retrofit work, so the WC-3000PSI welded cylinder fits legacy fluid lines without brass adapters.
05 · Balanced Clevis Geometry
Rod-end and cap-end clevis widths are matched so side-load on the pin is symmetric. That small detail extends seal life in oscillating-angle duty such as lift-gate and tilt-bed service.
06 · Full Production Traceability
Every WC-3000PSI welded cylinder is marked with a build code linked to raw-material batch and seal-kit lot. Years later we can still identify the exact chrome supplier used on your rod.
작동 원리 및 구조
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.

고객 사례 연구
Customer Success: How a Polish Implement OEM Cut Warranty Returns with the WC-3000PSI
고객: RolStalPol Agricultural Implements Sp. z o.o. — three-point-hitch implement builder based in Poznań, Poland
프로젝트: Replace a bolted tie-rod cylinder on a line of tractor-mounted rear mowers and rotary tillers that was showing 6-7% return rates for end-cap weep after 18 months of field use in Central European dairy country.
해결책: EVER POWER engineering substituted two WC-3000PSI welded cylinder SKUs — WC3030XX at 16" stroke and WC3040XX at 20" stroke — with upgraded Viton primary seals and pin-size confirmed at 1" to match the existing bracket pattern. Production ran through our Hangzhou plant and shipped via Ningbo Port into Gdańsk on a regular four-week cadence.
결과: After the first full season, end-cap weep returns fell to 0.4%. RolStalPol standardised the two implement lines on the WC-3000PSI welded cylinder platform and added a third rear-mower SKU to the frame contract the following spring.
고객들이 하는 말
“We swapped out the old bolted cylinders on our hook-lift trucks for the WC-3000PSI welded clevis design two years ago and have not had a single pivot-yoke failure since. The welded joint is visibly heavier than the competing parts we tested.”
“Drawings arrived fast, samples matched the quote tolerance, and the welded clevis hydraulic cylinder production line delivered the container eight days ahead of the promised date. That is unusual for Chinese-sourced hydraulics.”
“The pivot-bracket fitment on the WC-3000PSI cylinder is spot-on — we did not have to rework a single bracket hole in the first production batch of five hundred units.”
항저우 공장 내부

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.
품질 및 테스트 프로그램
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.

자주 묻는 질문
How much does a WC-3000PSI welded clevis hydraulic cylinder cost from a China supplier?
The unit price for a WC-3000PSI welded clevis cylinder from our Hangzhou facility varies with bore size, stroke length, order quantity, and any custom rod-eye or finish spec. For a 2.5" bore with a 16" stroke in container-load volume, pricing is typically competitive against North American and European equivalents once sea freight is included. Send your bore, stroke, and annual offtake through the contact form and we will return a written quote within one working day.
What is the minimum order quantity for a WC-3000PSI welded clevis cylinder for agricultural OEMs?
For standard catalog WC-3000PSI SKUs we accept orders starting at 20 pieces per part number. Prototype quantities of 1-5 units for qualification testing are available with a modest setup surcharge. Regular shipment batches range from 500 to 2,000 units for agricultural implement OEMs across Europe and North America.
Which welded clevis cylinder supplier in Hangzhou China handles custom rod-eye threads?
EVER POWER Hydraulic Machinery in Hangzhou has an in-house CAD team that draws non-catalog rod-eye thread patterns, clevis width variations, and extended strokes up to 72". Share the existing part drawing or a bracket sketch and we will return a 2D/3D file for your sign-off before any steel is cut.
How do I request a price quote for WC-3000PSI cylinders for my tilt-deck trailer build?
Use the Inquire Now button or fill the contact form with trailer deck length, target tilt angle, pin centers at both ends, and your annual production plan. Our Hangzhou sales engineering desk returns a price quote along with a recommended bore and stroke combination within 24 hours during Chinese business days.
What makes a welded clevis cylinder better than a tie-rod cylinder for articulating boom applications?
Articulating booms see oscillating angular loads that can fatigue the threaded joints on a tie-rod design. A welded clevis hydraulic cylinder carries the pivot load directly through a welded yoke with no fasteners in the primary load path, so the assembly cannot loosen over time. That is why boom OEMs often specify the welded clevis platform.
Where can I buy a WC-3000PSI welded clevis cylinder with fast delivery to my European port?
We ship directly from our plant in Hangzhou, China to Ningbo Port, and from there to any global seaport including Hamburg, Rotterdam, Antwerp, and Gdańsk. Typical production-plus-transit time runs 35 to 55 days. Inland dispatch to Shanghai or Guangzhou for domestic buyers takes three to five working days.
Which bore size should I pick for a 20,000 lb pivot-lift application on a hook-lift truck?
For a 20,000 lb working load, the WC3030XX with a 3" bore provides a rated column load of 21,200 lbs at 3000 PSI — a close fit. For additional margin, step up to the WC3035XX at 3.5" bore which delivers 28,800 lbs. Share your linkage geometry and we will confirm the stroke and pin center recommendation.
