Extension Springs and Coating Options

 

Before making a purchase, please note that actual products may vary slightly from the images due to internet and display variations. Contact our sales team for personalized assistance. Our extension springs, compression springs, torsion springs, and wire forms are fully customizable. We value Drawing-Guide Production, so remember to include a spring drawing when making inquiries. Your questions are always welcome!

 

Different Hook End Types of Helical Extension Springs

 

Extension springs come with various hook end types for easy attachment to force sources. Common options include machine loop and crossover loop. Unlike compression springs, extension springs lack a solid stop, resulting in reduced stress levels. Drawbar springs, a unique type of compression spring, feature a solid stop and special hooks.

 

Available Coating Methods

 

Our coating materials comply with RoHS standards to align with environmental policies. Opt for RoHS standard coating whenever possible. Consult the table below for the cost breakdown of each coating method.
