Product Specification

Conical Progressive Rate Compression Spring – Anti-Buckling, Compact Nesting Design, Durable Steel Material, OEM Customization

Product Description

The Conical Progressive Rate Compression Spring is a high-performance spring designed to deliver variable load resistance and superior stability in compact mechanical systems. Unlike standard cylindrical springs, this conical (tapered) design allows the coils to progressively compress into each other, enabling a space-saving nesting effect while maintaining consistent force output.

Engineered with progressive spring rate characteristics, the spring provides low initial resistance with increasing stiffness under compression, making it ideal for applications requiring controlled motion, shock absorption, and enhanced durability.

Manufactured from high-quality spring steel, this compression spring ensures excellent fatigue resistance, corrosion protection, and long service life, even under repeated loading conditions. The anti-buckling structure further improves performance by minimizing lateral deflection, ensuring smooth and reliable operation in demanding environments.

We offer full OEM and ODM customization, including dimensions, materials, surface treatments, and load specifications, to meet diverse industrial requirements.

FAQ

Q1: Can you customize the spring according to our drawings?
Yes, we specialize in OEM and ODM manufacturing based on drawings, samples, or technical requirements.

Q2: What materials are available?
We offer carbon steel, stainless steel (such as SUS302/304/316), and alloy steel depending on your application.

Q3: What is a progressive rate spring?
A progressive rate spring provides increasing resistance as it is compressed, offering better control and shock absorption compared to constant-rate springs.

Q4: Can you provide samples?
Yes, samples are available for testing and evaluation before mass production.

Q5: What is your production lead time?
Lead time depends on order quantity and complexity, typically ranging from 7 to 25 days.

Q6: How do you ensure product quality?
We follow strict quality control standards, including material inspection, dimensional checks, and performance testing.
