What Are Compression Springs?

Compression springs are open-coil helical springs designed to compress under a load. They operate by shortening their length when subjected to pressure, creating a restoring force that pushes back against the applied load. Олардың әмбебаптығы, тиімділігі, and ease of customization make them suitable for a wide range of applications.

How Compression Springs Work

Compression springs are placed between two components. When force is applied, the spring compresses and stores potential energy. Upon releasing the load, the spring returns to its original shape, жинақталған энергияны босату.

Key Features:
