Product Highlights:

l High-Elasticity Stainless Steel Material

Made of high-quality stainless steel wire with excellent elastic recovery and fatigue resistance for stable force output after repeated compression.

l Precision OD & Straightness Control

Tight OD tolerance (±0.05mm) and straightness ensure accurate fit with mounting holes, preventing jamming or misalignment.

l Flat-End & Deburring Treatment

Both ends undergo flat grinding and deburring for smooth, flat surfaces, ensuring tight contact with mating parts.

l Multiple Surface Treatment Options

Supports gold plating, nickel plating, or phosphating for enhanced corrosion resistance and electrical conductivity.

l Customizable Specs & Force Adjustment

Customizable wire diameter, coil count, free length, and compression stroke with adjustable force values for diverse applications.
