About Chain in hardwire

A chain is an assembly of two or more connected links, typically made of metal. It is flexible like rope but rigid, linear and load-bearing in tension.


Chains are classified be their use and design:


  • Some chains are designed for lifting, pulling, or securing. They have torus shaped links and are flexible in two dimensions; the fixed third dimension is the chain’s length.


  • The second class of chains are designed for transferring power in machines. Their links mesh with the teeth of the cogwheels of the machine. These chains are called roller chain and are flexible in only one dimension.
