HCIC Welded Hydraulic Cylinders
Product Description
Product Detail
Need a hydraulic cylinder that won’t quit when the going gets rough? HCIC welded cylinders are built for real-world heavy use – construction sites, garbage trucks, mining equipment, you name it. They’re rated for pressures from 16MPa up to 35MPa, with bore sizes from 50mm to 250mm and strokes up to 4000mm. In our customer tests, they cut on-site failure rates by about 20% compared to standard cylinders.
1. Basic Product Info
1.1 What Are These Welded Cylinders?
Simply put, HCIC welded hydraulic cylinders don’t use tie rods. The tube and end caps are welded together into one solid piece. No loose parts, no wobbly connections. They’re made for high pressure, heavy loads, and all the shock and vibration that comes with running equipment hard.

2. Where These Cylinders Work Best
2.1 Construction Machinery
These cylinders are built for excavators, loaders, bulldozers, rollers, pavers – all the gear that sees non-stop action on job sites. They handle boom, arm, and bucket movements without skipping a beat, even in dusty, high-impact conditions.
2.2 Special Vehicles
We see these on dump trucks, garbage compactors, aerial lifts, and tow trucks every day. They’re made for long-stroke lifting, high pressure, and constant start-stop cycles.
2.3 Mining & Heavy Industry
Mining equipment, metallurgical machines, presses, port cranes – these are tough environments. Our welded cylinders stay stable even in dusty, vibrating, full-load operations.
3. Key Features That Matter
3.1 Compact, Sturdy Build
No tie rods mean a tighter, stronger structure. They fit in the tight spaces modern equipment has, and they won’t come loose on the job.
3.2 Built to Take Shock and Loads
These cylinders handle sudden shocks and side forces like a champ. The welds go through stress relief, so they don’t warp or crack even with long-term heavy use.
3.3 Seals That Don’t Leak
Precision-honed tubes plus multi-stage seals keep leaks to a minimum. They work consistently in hot and cold conditions alike.
3.4 We Can Customize Them
Need different port positions? A specific mount? Cushioning or sensor ports? We adjust all of that to fit your equipment exactly.
4. Why Go With HCIC?
4.1 We Make These In-House – No Middlemen
HCIC runs three modern factories and our own R&D center. Every cylinder is built to standard specs, pressure-tested, and run-tested before it ships. You get full traceability on every unit.
4.2 They Last Longer – Simple as That
Our customers in construction and mining tell us these cylinders last up to 30% longer than standard ones, with about 25% longer time between failures. That means less downtime and less maintenance work for you.
4.3 Quality Materials, Certified Standards
We use high-strength alloy steel for the main parts, and our welding meets ISO 6020/2 standards. The seals are top-tier, too, so they don’t wear out early.
4.4 Our Team’s Got You Covered
We’ve got engineers, production staff, sales reps, and after-sales techs all on one team. We handle everything from design to production to testing, all under one roof. Plus, every HCIC hydraulic cylinder comes with a 1-year warranty, and we’ve got all the industry certifications to back it up.
