Extension Springs

Shandong Gold-Star Spring Co., Ltd. is one of the leading manufacturers and suppliers of extension springs in China. Please rest assured to buy durable extension springs made in China here from our factory. All customized products are with high quality and low price.

Helical extension springs store energy and exert a pulling force.  Extension springs differ from compression springs in that they do not have a solid stop to prevent overloading.  For this reason, they are designed with lower stress levels.  Typical applications include balance scales, trampolines, garage doors, dock levelers, farm machinery and various types of spring tensioning devices.  Extension springs come in a wide array of sizes from small medical devices to off-road machinery brake springs.

In order to be a part of an assembly, extension springs require a method of attachment.  Threaded inserts, swivel hooks, twisted loops and side loops are just a few of the nearly limitless options available.  At the design stage, the length and positioning of the hooks at each end of the spring can be adjusted in order to obtain exactly the required spring load at any extended position.  Silencers can be used to prevent vibration within the spring itself as well as eliminating noise in the application without upsetting the function of the spring.
