Roller Chain Offset Links

Friday, November 17th, 2017

What is a roller chain offset link? First, a roller chain link is the interior assembly of a chain that consists of two bushings pressed into each of the link plates. It may also include rollers if applicable. However there are also rollerless chains available for specific situations. It is important to know that the same roller links can be used for both multiple and single strand chains.


Roller Chains And Roller Chain Links

Roller chains are used as the chain drive for many types of commonly used machinery. The chain, also known as a bush roller chain, powers industrial, domestic, and agricultural machinery, including cars, conveyors, bicycles, and motorcycles.

The chain is constructed from roller chain links held together by side links. The entire chain is then driven by a sprocket, a toothed wheel which turns, pulling the chain.

Hitachi — Inspire the Next

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.

Ordering Cut-To-Length roller chains

Cut-To-Length roller chains may be ordered in a variety of configurations with an odd or even number of pitches. When ordering it is important to specify both the length in pitches and the configuration including whether a strand contains connecting links, offset links, etc. Conversion tables are available to our salespeople for converting pitches to feet.

The following are the most common configurations for roller chains:

Even number of pitches:

8 Pitches Connecting link at one end
16 Pitches Endless (no connecting link)

Odd number of pitches:

7 Pitches one connecting link and one offset link
7 pitches roller link at each end
7 pitches one connecting link at each end

And the chain of choice is Hitachi Maxco, with 3 stateside locations in Atlanta, GA; Portland, OR; and Chicago, IL. 

In 1987 Hitachi Maxco, Ltd, introduced the first premium line of solid bushing/solid roller industrial roller chains to the North American marketplace.  Technology advanced manufacturing and part finishing techniques allow this series to competitively replace traditional curled components and extend chain life.

Today, Hitachi continues to invest heavily in developing advanced product solutions for industry.  Their innovations in the area of chain strength and wear performance, corrosion protection and maintenance free operation are solving problems, and providing value to their customers and partners.

Whether for power transmission or conveying; in the food and beverage, packaging, forest products, mining, pharmaceutical, automotive, or high-speed printing industries, count on Hitachi to provide the ultimate in performance and value in industrial roller chain products.


In 1997, Hitachi added a unique coating to pins and bushings and re-designed the connecting line.  A good product was made better as their design focus shifted to improving chain wear life and improving the endurance of the connecting link.

The new coating assisted lubrication and protected against corrosion.  A 5%-10% increase in wear life was achieved and Hitachi roller chains were now challenging the best products in the world.


Today Hitachi stands poised to offer a quantum leap in the performance of standard roller chain.  New innovations in manufacturing technologies and parts processing have led to the development of their new INSPIRE SERIES SBR line of standard roller chain products.

A unique patent pending, “Hi-Energy Mechanical Process” is performed on all of the chain’s components and has yielded surprising benefits in both the fatigue strength and wear performance of this remarkable new series.  Hitachi’s  INSPIRE SERIES SBR chains possess the highest working load and horsepower capacity ratings in the world.
