Short German Hook Tension Springs/Extension Springs

  Side-hook extension springs refer to springs with hooks designed on the edge rather than at the spring’s mean diameter.This design allows the hooks to achieve more precise positioning during extension and provides more stable tension when under load.  Side-hook extension springs are suitable for applications where the hooks engage on flat or planar surfaces. Like other extension springs, they operate by exerting a counteracting force using the restoring tension when stretched.

  Long German hook extension springs are a common type of extension spring featuring long German-style triangular hooks at both ends.This design increases the contact area between the hooks and the fixture under load, enhancing grip and thereby improving the spring’s reliability.  Long German hook extension springs are mostly used in electronic and electrical products. Like other extension springs, they operate by exerting a counteracting force when stretched, utilizing the restoring tension force.

  Swivel hook extension springs are a highly versatile type of extension spring.Unlike standard hooks, the hooks on both ends of a swivel hook extension spring are designed to freely rotate, which greatly enhances the spring’s flexibility and allows it to perform exceptionally well in various specialized equipment.  They are primarily used in mechanical devices, and the main difference from regular hooks is that both ends can rotate, providing added adaptability. Therefore, swivel hook extension springs are considered a highly practical spring type, widely used across many fields due to their flexible nature.  When selecting a swivel hook extension spring, it is important to consider the specific application requirements, taking into account factors such as hook type, material, and dimensions. These factors are often critical and make swivel hook extension springs the preferred choice for many customers.  Swivel hook extension springs are a very practical type of spring, and their flexible characteristics enable them to be widely used in numerous industries. When choosing a swivel hook extension spring, it is essential to comprehensively evaluate the hook design, materials, and dimensions according to the specific application needs.

  Small outer diameter extension springs are mostly customized products requested by customers. They are helical springs that elastically deform under axial tensile force. Unlike compression springs, extension springs typically have coils that are tightly wound without external force applied, requiring a certain amount of tension to separate the coils.  These extension springs feature a small outer diameter with hooks at both ends. Due to their small outer diameter, they can provide strong tension even in limited space, making them widely used in precision instruments, electronic products, and other fields.
