51317386 / 513 173 86 PISTON INGERSOLL RAND

High-impact rock drilling systems depend on one core moving element to convert hydraulic or pneumatic energy into raw striking force: the piston. The 51317386 / 513 173 86 piston is engineered to operate at extreme cycle speeds, delivering consistent impact energy while maintaining dimensional stability under continuous load.

Supplied globally by 3GEN Export as an OEM-grade replacement, this component is manufactured to tight tolerances and shipped worldwide within 5 working days.

Designed for demanding quarrying, mining, and construction environments, this piston integrates seamlessly into compatible Ingersoll Rand rock drilling platforms, helping operators maintain penetration rates, reduce downtime, and extend service intervals.

What Makes the 51317386 / 513 173 86 Piston Critical in Rock Drilling Systems

Inside every drifter or rock drill, the piston performs thousands of high-energy strokes per minute. Each movement transfers force directly to the shank and drill steel. Any deviation in geometry, surface finish, or material hardness can result in:

• Reduced impact efficiency

• Premature wear of mating components

• Heat buildup inside the cylinder

• Loss of drilling accuracy

• Increased maintenance cycles

The 51317386 / 513 173 86 piston is produced from high-strength alloy steel and finished with precision grinding to ensure:

• Stable reciprocating motion

• Low friction against the cylinder liner

• Balanced load distribution

• Long operational lifespan under abrasive conditions

At 3GEN Export, we supply this piston as an OEM-standard replacement part, manufactured to closely match original dimensional and performance requirements.

Manufacturing Approach and Material Structure

Each unit is produced using controlled machining and finishing processes designed for heavy industrial use.

Key production characteristics include:

• Heat-treated alloy steel core for impact resistance

• Precision-ground outer diameter for consistent clearance

• Polished sliding surfaces to minimize friction losses

• Carefully chamfered edges to protect seals and liners during installation

These steps ensure the piston maintains stability during high-frequency operation while resisting deformation and surface fatigue.

Functional Role Inside the Drifter Assembly

Within the rock drill, this piston acts as the primary energy transfer element. Pressurized fluid or air accelerates the piston forward, generating impact energy that is transmitted through the striking mechanism to the drill steel.

During operation, the piston must:

• Maintain straight axial travel

• Withstand repetitive shock loads

• Operate smoothly inside the cylinder liner

• Retain dimensional accuracy over extended duty cycles

The 51317386 / 513 173 86 piston is engineered to perform these tasks reliably in both surface and underground applications.

Typical Applications

This component is commonly installed in rock drilling systems used across:

• Open-pit mining

• Underground tunneling

• Quarry operations

• Foundation drilling

• Road and infrastructure projects

• Geotechnical exploration

Its design supports continuous heavy use in abrasive environments where consistency and durability are essential.

Technical Overview (Typical)

While exact dimensions may vary by configuration, this piston generally features:

• Material: High-strength heat-treated alloy steel

• Surface finish: Precision polished sliding areas

• Function: Impact energy transfer within drifter assembly

• Installation type: Internal reciprocating component

• Operating environment: High-load, high-frequency rock drilling systems

Approximate Weight

• Estimated weight: ~7.5 kg

(Final weight may vary slightly depending on production batch.)

Compatible INGERSOLL RAND Rock Drill Models

The 51317386 / 513 173 86 piston is commonly used in selected INGERSOLL RAND drifter and rock drill assemblies, including configurations found in:

• HL series drifters

• Medium-to-heavy percussion rock drills

• Hydraulic drilling platforms utilizing matching internal assemblies

If you are unsure about compatibility with your specific machine, 3GEN Export can confirm fitment using your equipment model or serial number.

Installation Recommendations

For optimal performance and service life:

• Inspect cylinder liner for scoring or ovality before installation

• Replace worn seals during piston change

• Apply proper assembly lubrication

• Verify axial alignment during reassembly

• Perform initial low-load run-in after replacement

Correct installation significantly improves operational stability and helps protect surrounding components.

Common Wear Symptoms Indicating Replacement

A worn or damaged piston may present:

• Reduced penetration speed

• Irregular striking sound

• Increased vibration

• Metal particles in hydraulic oil

• Visible scoring on the piston surface

Replacing the piston at early signs of degradation prevents secondary damage to liners, valves, and bushings.
