General Information

Chain Construction

Riveted Chain

Riveted chains possess pins which are dual staked on both sides of the chain.

Cottered chain

Cottered chains possess pins which are dual staked on one side of the chain. On the other, the chains have cottered pins assembled through drilled holes. Cottered chains are slightly easier to assemble and disassemble in the field and are more common on larger pitch chains. Cottered chains are available from stock beginning with 3/4 inch pitch (#60) chain.

Multiple strand chain

Multiple strand chains are available when space is limited on roller chain drives. These chains allow the horsepower capacity to be increased, without increasing the diameter of the sprockets. Middle link plates are slip fit as standard however, press fit plates are available for severe applications.
