Hydraulic Tie-Rod Type Cylinders TR-3000PSI: Rebuildable Industrial Hydraulic Actuation

Tie-rod construction hydraulic cylinders engineered for rebuild-friendly service and the full NFPA/ISO industrial mounting pattern.

TR3020XX - TR3050XX  |  Bore 2" to 5"  |  ASAE Agricultural Option

The hydraulic tie-rod cylinder TR-3000PSI targets industrial users and rebuilders who want a cylinder they can pull apart, re-seal, and put back into service. Every hydraulic tie-rod cylinder in the TR-3000PSI family uses four threaded tie-rods to hold the end caps onto the barrel, which means any service shop with basic tools can open the cylinder, replace the seal kit, inspect the rod, and reassemble to spec. Bore sizes run from 2" through 5", the ASAE agricultural mounting standard is available, and the TR-3000PSI tie-rod cylinder is rated for a consistent 3000 PSI working pressure across the full catalog.

EVER POWER has been building the hydraulic tie-rod cylinder for more than two decades out of Hangzhou, and the TR-3000PSI design is cross-compatible with NFPA / ISO industrial mounting dimensions. That means an end-user who previously stocked Parker, Atlas, or Rexroth tie-rod parts can typically drop a TR-3000PSI tie-rod cylinder onto the same machine bracket without modification. Over thirty export markets validate that interchangeability with repeat orders every quarter.

Why Choose EVER POWER TR-3000PSI?

A hydraulic tie-rod cylinder earns its place where rebuild economics matter. An end-user who pays $400 for a new welded cylinder typically wants to pay $60 for a seal kit on a TR-3000PSI tie-rod cylinder five years later rather than buying a replacement. Here are the six engineering details that make the hydraulic tie-rod cylinder a rebuild-friendly asset instead of a throw-away part.

Working Principle & Construction

A hydraulic tie-rod cylinder is built around four threaded rods that clamp the head and cap against the barrel. Oil pressure tries to push the heads apart; the tie-rods hold them together. Because there is no welded joint in the primary load path, the cylinder can be disassembled by backing off four nuts, which is how the TR-3000PSI tie-rod cylinder delivers rebuildability. Every tie-rod is rolled-thread as standard, and preload torque is specified in the service folder for every bore size.

Raw-material selection follows the same EVER POWER standard as the rest of our catalog. Barrels are cold-drawn seamless steel tube honed to mirror finish. Rods are induction-hardened and hard chromed. End caps are machined from 45# forged steel with integrated port bosses. The seal stack on a hydraulic tie-rod cylinder is typically more accessible than on a welded cylinder, so seal compound choice tends to favour longer service life — Polyurethane primary and Nitrile secondary is standard, with Viton, EPDM, and fluorosilicone compounds stocked for specific fluid chemistries.

The TR-3000PSI tie-rod cylinder is dimensionally compatible with NFPA T3.6.7 and ISO 6020-2 mounting standards. Buyers replacing a legacy Parker 2H, Atlas 3200, or Rexroth CD series part can typically match dimensions without bracket rework. Retracted and stroke tolerance holds to ±1/8", extended working pressure is de-rated on long-stroke SKUs per the datasheet, and every hydraulic tie-rod cylinder leaves Hangzhou with rod anti-corrosion plugs in both ports. Hydraulic pressure-test on sampling is standard.

Standard Specifications

Maximum retracted working pressure 3000 PSI. For 8.00" ASAE stroke A = 12.25"; for 16.00" ASAE stroke A = 15.50". Extended working pressure de-rated per datasheet. NFPA / ISO industrial mounting compatible.

Typical Applications of the TR-3000PSI

A hydraulic tie-rod cylinder is specified where rebuild economics or NFPA interchangeability dominate the purchase decision. The TR-3000PSI range has been installed on injection-molding platen rigs in American plastics plants, on hydraulic press feeders in German tooling shops, on agricultural sprayer boom folds across Ukrainian grain country, and on log-splitter power units for European firewood operators. The hydraulic tie-rod cylinder handles each of these jobs because the rebuild-friendly architecture keeps total cost of ownership down, and the TR-3000PSI tie-rod cylinder pressure envelope matches the demands of those industrial and agricultural duty cycles cleanly.

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 hydraulic tie-rod cylinder line since 2002, with current annual capacity of 120,000 cylinders across the full catalog including the TR-3000PSI platform.

Our quality system is ISO 9001:2015 certified. Every hydraulic tie-rod 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 TR-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 hydraulic tie-rod 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 TR-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 TR-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 hydraulic tie-rod cylinder shipments leave our Hangzhou plant in fumigated wood crates with port-protection caps on ports and desiccant inside the cylinder bore.
