Restore Peak Performance: Aftermarket Cylinder for DNB D160IIs Breaker
OEM Part Number: 9181-0120
Compatible With: DNB D160IIs Hydraulic Hammer/Breaker
Is your DNB D160IIs hydraulic hammer losing power, suffering from low blow frequency, or leaking hydraulic fluid? A worn cylinder isn’t just a single-part failure—it’s the beginning of a cascade of damage that can lead to catastrophic and costly repairs. Don’t let a failing cylinder compromise your entire operation.
Our precision-engineered aftermarket cylinder is the direct, high-quality replacement you need to get your DNB D160IIs back to breaking at its full force, reliably and efficiently.
Why a Worn Cylinder is Your Breaker’s Biggest Enemy
The cylinder is the central chamber of your hydraulic hammer. When its bore becomes scored, pitted, or out-of-spec, it causes:
- Catastrophic Power Loss: Inefficient transfer of hydraulic energy results in weak, ineffective blows.
- Accelerated Component Wear: A damaged cylinder bore will quickly destroy piston seals, damage the piston itself, and contaminate the entire hydraulic system.
- Costly Downtime: What starts as a minor performance issue can swiftly lead to a complete, unexpected breakdown.
The Smart Alternative to Overpriced OEM Parts
Why pay a premium for an OEM cylinder when you can get superior value without sacrificing quality or performance?
✅ Guaranteed Perfect Fit & Function
- Direct Replacement for 9181-0120: Manufactured to exact OEM dimensional tolerances for a seamless install.
- Flawless Internal Alignment: Ensures optimal performance with the piston and seal kits, preventing premature wear.
✅ Engineered for Maximum Durability
- High-Grade Alloy Steel: We use robust materials designed to withstand the extreme pressures and impacts of hydraulic breaking.
- Precision Hardening & Finishing: Our advanced heat treatment and honing processes create an incredibly hard-wearing bore with a mirror-smooth surface. This maximizes the service life of your seals and minimizes internal friction.
✅ Unbeatable Value
- Significant Cost Savings: Achieve OEM-level quality and durability at a fraction of the cost, maximizing your return on investment (ROI) for maintenance.
- Extended Breaker Lifespan: Protect your investment by replacing the core component with a part built to last.
Don’t Wait for a Total Breakdown!
A failing cylinder won’t fix itself. Proactive replacement saves you from more extensive repairs and expensive downtime.
