Duke 175551 Chain,Roller #35 , 24 Long (63

A chain is a serial assembly of connected pieces, called links, typically made of metal, with an overall character similar to that of a rope in that it is flexible and curved in compression but linear, rigid, and load-bearing in tension. Those designed for transferring power in machines have links designed to mesh with the teeth of the sprockets of the machine, and are flexible in only one dimension. A roller refers to a wheel or a revolving cylinder over or on which something is moved or which is used to press, shape, spread, or smooth something in a rolling motion. Machines employing conveyor systems often utilize rollers as do drawers, cabinets, and sliding doors.
