Description

✅ Product Overview:

The Compression Spring NQ is a precision-engineered, load-bearing spring used in NQ-size inner tube head assemblies for wireline core drilling systems. It provides the critical restoring force required to keep internal mechanisms aligned, allowing for smooth and safe core recovery during drilling.

This spring is an essential spare part for maintaining your core barrel assembly’s performance, especially in demanding mineral exploration, geotechnical, and diamond drilling environments.

🔩 Key Features and Benefits:

• High-Strength Spring Steel – Heat-treated and tempered for superior tension and durability in high-cycle drilling conditions.

• Corrosion-Resistant Finish – Suitable for wet, muddy, and chemically reactive drilling sites.

• Consistent Compression Force – Maintains steady tension to ensure reliable operation of internal components.

• Precision Fit for NQ Head Assemblies – Manufactured to exact NQ dimensions, ensuring compatibility and secure installation.

• Extended Service Life – Built to withstand repeated stress cycles without permanent deformation or fatigue.

🔧 Function and Application:
