Single pitch chain
This chain is connected by hollow pins, and the hollows could be used to attach a variety of attachments. In hollow pin chain, the hollow pins are the identical because the bushings on the corresponding typical chain in diameter, so hollow pin chain can be regarded as bushing chain that includes bushings on the very same diameter as that of the rollers of the corresponding common chain.
Common sprockets may be employed.
The connecting back links are distinctive snap ring forms for hollow pin chain as illustrated.
Given that no offset link is available, the number of hyperlinks should be an even number.
Flexible Chain
Versatile Chain has great sideward bending flexibility and is suitable for curved traveling. Sprockets for 
JIS/ANSI Regular Roller Chain can be utilised for this chain. By fixing attachments, this chain is often applied for curved transfer with conveyors.
Flat Sort Roller Chain
This chain is suited for conveyor systems since it has flat plates that result in little harm to elements such as chain guides. (The types of outer plates and inner plates are the same.)
