Product Description

The SPEC Compression Spring (SKU D20440, MPN D20440) is a cylindrical compression spring made from 302 Stainless Steel, with a length of 12.5 mm and an outer diameter of 1.85 mm, supplied in a pack of 10. This product is a standard industrial spring for applications requiring a compact, corrosion-resistant component.

Frequently Asked Questions

What is a SPEC compression spring used for?

A SPEC compression spring is used to store mechanical energy and resist compressive forces in industrial assemblies. Common applications include valves, actuators, switches, and small mechanisms where a compact, corrosion-resistant component is needed. The 302 stainless steel construction suits environments requiring moderate corrosion resistance.

What are the specifications of the SPEC D20440 compression spring?

The SPEC D20440 compression spring is made from 302 stainless steel, has a cylindrical shape, a length of 12.5 mm, and an outer diameter of 1.85 mm. It is supplied in a pack of 10. These dimensions make it suitable for compact industrial applications where precise spring force is required.

Where to buy SPEC compression springs worldwide?

3G Electric supplies SPEC compression springs worldwide. As a global industrial solutions provider, we handle full logistics and customs clearance to deliver the D20440 and other SPEC spring packs to your facility. Contact us for a quote and lead time on this 302 stainless steel spring.

How to select a compression spring for an industrial application?

To select a compression spring, determine the required free length, outer diameter, wire diameter, and material based on load and environment. For corrosion resistance, 302 stainless steel like the SPEC D20440 is a common choice. Ensure the spring's dimensions fit the assembly and that its spring rate meets the force requirements.
