Lucas Chain Roller Offset Link

The Lucas Chain Roller Offset Link, also called a half link or crank link, lets you build or repair a roller chain that needs an odd number of links. Standard roller chain is made of paired inner and outer links, so an even link count is normal. An offset link adds the extra pitch needed to reach the right chain length.

Key Features:

• Adds one pitch to a roller chain so you can reach an odd link count
• Lets you adjust chain length without replacing the whole chain
• Handy for quick repairs when a damaged link needs replacing
• Uses offset side plates, a roller, a bushing and a pin, and is secured with a cotter pin
• Installs in place of a removed link, and the chain tension should be checked afterward

Installation Notes: Choose an offset link that matches the pitch and size of your chain. Seat the pin through the adjoining links, then secure it with the cotter pin. Bend the cotter pin ends so they do not extend past the plate height. Offset links are generally rated lower in strength than a standard chain link. For the most demanding loads, a chain built with an even number of links is the better choice.
