Zinc-plated Tapered Compression Spring

  A type of compression spring used in firearm magazines or similar cartridge-feeding mechanisms. It provides the necessary upward force to feed bullets or components.

The compression spring is a common type of spring primarily used to withstand axial compressive loads. With its simple structure and stable elasticity, it is widely utilized in various mechanical equipment, automotive components, electronic devices, and industrial applications.This product features a high-quality painted surface finish that not only enhances its appearance but also provides excellent rust and corrosion resistance, effectively extending the spring’s service life. The paint color and coating thickness can be customized according to customer requirements, offering both functionality and aesthetic appeal.

  A blackened magazine compression spring refers to a compression spring used in magazines that has undergone blackening treatment (also known as black oxide coating). It is commonly used in firearms, tools, or other devices that require propulsion or energy storage.  

  A garter spring is a tension spring formed into a circular shape and installed inside oil seals (such as rotary shaft seals or mechanical seals). Its primary function is to maintain continuous radial pressure on the sealing lip against the shaft to ensure effective sealing performance.
