A Guide to Extension Spring Hooks and Loops

A Guide to Extension Spring Hooks and Loops

The hooks and loops play a crucial role in transmitting force and enabling the essential functions of extension springs. These end configurations can be customized in various types to suit specific applications.

Types of Hooks and Loops #

  1. Machine Hooks: These are the most widely used hook style, offering a strong and direct connection. They are formed by bending ¾ of a coil outwards, providing a robust anchor point for pulling forces.
  2. Side Loops: Also known as cross-over hooks, these are positioned over one side of the spring body, offering a more compact design. They are particularly useful when space is limited or when the spring needs to be offset from its center.
  3. Center Loops: hook that is attached to the center of an extension spring. It is commonly used in applications where it is important to maintain a balanced load.
  4. Extended Hooks: These hooks extend further away from the spring body, providing a longer reach and more leverage for pulling forces. They are often used in applications where space is not a constraint and where a stronger pulling action is required.
