hydraulic cylinder for excavators:125/75-280

At HCIC, we’ve built the 125/75-280 excavator hydraulic cylinder to handle the gritty, real-world demands of construction sites—no shortcuts, no generic specs, just reliable performance that keeps your machines moving. We use heavy-duty alloy steel for the barrel and rod, and every piece is machined to tight tolerances by our in-house team, so it holds up to constant boom, arm, and bucket movement, even when digging in rocky soil or lifting heavy loads.

The 125mm bore, 75mm rod, and 280mm stroke aren’t just numbers on a spec sheet—they’re sized to balance power and efficiency for mid-sized excavators, the workhorses of most construction fleets. We test every hydraulic cylinder to 35 MPa pressure (that’s over 5,000 psi) before it leaves the factory, and we check for leaks and fatigue under real operating conditions, not just lab settings. It’s why HCIC customers tell us they replace these cylinders far less often than cheaper alternatives.

And here’s the thing: not every job fits a “standard” cylinder. If your excavator has custom mounting points, or you need a different stroke length for a specialized task (like demolition or deep trenching), HCIC engineering team doesn’t just tweak a design—we build it from the ground up to your exact specs. We’ve done custom cylinders for everything from mini-excavators to large mining machines, and we keep lead times tight because we know downtime costs you money.

For procurement teams and equipment managers, choosing HCIC means you’re not just buying a part—you’re buying a solution that fits your workflow. Whether you need a pallet of 125/75-280 cylinders for your fleet or one custom-built unit for a unique project, we’ve got the capacity and expertise to deliver, on time and to your standards.For More details please email us "davidsong@mail.huachen.cc" or google search "HCIC hydraulic"
