| About Cotter Type Roller Chain

Standard and heavy-duty cotter type roller chains are made to ANSI standard from size 50 to 240 in single, duplex and triple strands.

Cotter roller chains are designed to assemble and disassemble more easily than riveted roller chain.

However, the outer plates are still press-fit style and require enough pressure to remove the plates.

In addition to cotter roller chains in our catalog, it is possible to have cotter pin type design for other chains.

Additional cotters, pin links, roller links, connecting links (master links), and offset links (half links) are available for fixing or customizing the length.
