51317303 / 513 173 03 Liner Cylinder – Ingersoll RandRock Drill Spare Part

OEM Manufactured by 3GEN Export – Worldwide Delivery in 5 Working Days

Professional Replacement Solution for High-Impact Rock Drilling Systems

The 51317303 / 513 173 03 Liner Cylinder Ingersoll Rand is a critical internal wear component designed to support piston movement and stabilize percussion energy inside hydraulic rock drilling equipment. This precision-machined liner creates a controlled operating surface for the hammer piston, helping maintain impact consistency, internal alignment, and long-term structural integrity of the drilling unit.

At 3GEN Export, we manufacture this liner cylinder as an OEM-standard replacement, engineered to match original dimensional tolerances and operational characteristics. We supply this part globally with 5 working days delivery, supporting mining, quarrying, tunneling, and foundation drilling operations worldwide.

What the 51317303 Liner Cylinder Does Inside the Drill

In hydraulic rock drills, the liner cylinder functions as the internal guide and protection layer for the main percussion piston. During continuous high-frequency impacts, enormous forces are generated. The liner absorbs surface wear while preserving the geometry of the main housing.

The 51317303 / 513 173 03 Liner Cylinder Ingersoll Rand provides:

• A smooth, hardened running surface for the piston

• Structural protection for the drill body

• Consistent impact alignment

• Reduced internal friction

• Improved service life of surrounding components

Without a properly manufactured liner cylinder, vibration increases, piston scoring occurs, and drilling efficiency drops rapidly.

OEM-Level Manufacturing by 3GEN Export

3GEN Export produces this liner cylinder using CNC-controlled machining and high-grade alloy steel selected for impact resistance and dimensional stability. Every unit is processed to achieve:

• Exact internal bore tolerance

• High concentricity for piston alignment

• Polished working surfaces

• Uniform wall thickness

• Pressure-resistant structural integrity

Each liner is inspected before shipment to ensure compatibility with existing rock drill assemblies.

We do not sell branded originals. Instead, we operate as an OEM supplier, delivering performance-focused replacements engineered to meet professional field demands.
