The Advantages Of Excavator Hydraulic Cylinder

Seals That Actually Seal

Triple-layered Swedish polyurethane seals (the kind used on offshore oil rigs) lock fluid in and dirt out. Tested at 3,500 PSI for 72 hours straight – zero leaks, zero excuses.

Rod That Laughs at Abuse

Hard-chromed piston rods with 3x thicker plating than cheap cylinders. Resists pitting from salt, acid soils, and abrasive slurry that destroys standard rods in months.

Excavator Hydraulic Cylinders That Won't Let You Down

Let's face it - when your cylinders fail, your whole job stops. That's why we built ours to handle the worst conditions: demolition debris, mining abuse, and extreme temperatures.

Here's what makes ours different:

✔ Leak-proof design - Triple-sealed with Swedish polyurethane (same as oil rigs)

✔ 3x thicker chrome plating - Resists pitting from salt, mud, and abrasives

✔ 2x longer lifespan than OEM in demolition and mining

✔ Same-day shipping - Beat OEM lead times by weeks

✔ Perfect fit for CAT, Komatsu, Hitachi - no modifications needed

Proven in the field:

→ 5,000+ hours in copper mines (where OEM fails at 2,500)

→ Withstands 12-ton concrete impacts in demolition

→ -40°F to 120°F performance (arctic and desert ready)

Bottom line? If you're tired of constantly rebuilding or replacing cylinders, it's time to upgrade to something that lasts.

FAQ

How do I know if my cylinder needs replacing?

If you're seeing oil leaks, slow operation, or jerky movements, it's time. Bonus signs: your machine sounds like it's groaning when lifting, or the rod looks pitted/scratched.

Will these survive demolition work?

Got crews using them to smash concrete daily – 3,800 hours and counting. The 3x thicker chrome plating eats rebar impacts for breakfast.

What Our Clients Are Saying

Mike D., Demolition Foreman

Been running these on our CAT 336 excavator in a demolition yard. Normally burn through OEM cylinders every 8 months. These? Still going strong after 14 months with zero leaks. The Swedish seals are bulletproof

Sarah L., Construction Fleet Manager

Did the math after switching our Komatsu fleet. Fewer replacements + less downtime = serious savings. Even our dealer asked where we got these cylinders.

Seals That Actually Seal

We use triple-layer Swedish polyurethane seals – the same stuff they put on offshore oil rigs. Tested at 3,500 PSI for 72 hours straight with zero leaks. No weep, no seep, no excuses.

Rods That Won't Pit or Scratch

Our 3x thicker hard chrome plating laughs at salt, acid soils, and abrasive slurry that destroy standard rods in months. No more replacing cylinders just because the rod looks like it went through a cheese grater.
