Chain

IDENTIFICATION SECRETS

There are several ways to identify chains.
Check your chain for the following features and dimensions.

(a)

There should be a number and/or brand on the side plate. If there isn't a number, check the charts below to find one. The one displayed here is an 'RS40' chain but does not show a brand. It is an RS shape.

(b)

The shape of the side plate.

(c)

Number of rows (refer picture)

(d)

Number of links (refer picture)

(d)

Chain Pitch (refer picture)

(d)

Lengths required (refer text)

(e)

What machine is the chain off?

MEASURING THE PITCH

Chain pitch is measured from centre to centre of the link pins.

OUNTING LINKS

How to count chain links.

Chain is comprised of inner and outer links. Both need to be counted.

How many rows is your chain. Although unusual, it could be more than three.

HOW MUCH DO YOU NEED

Now that we have identified your chain, we can work out how much you will need.

Most Chains are sold in 10ft (120") lengths so, to work out how many lengths you need, you will have to know the 'pitch' of your chain and the number of links it contains.

When you know that, use the formula 'Length divided by Pitch' to work out how many links of your chain will be in each 10ft length.

For example 120" divided by 1/2"=240 links for 1/2" pitch chain.

Common examples are.....

1/2"=240 links - 5/8"=192 links - 3/4"=160 links and 1"=120 links

So, if your chain had a 1/2" pitch and 200 links, you'd only need one length.

QUALITY

Chain quality makes enormous differences.

Other Materials

Engineered Ceramic Chain

At very high temperatures, Engineered Ceramic is the material of choice. It offers extreme heat resistance. It has endured repeated temperature changes from ambient up to 1,200degC.

Engineered Plastic Chain

Engineered Plastic Chain, on the other hand, can be run at temperatures between -20 and +80C. At higher temperatures it may become soft and lose it's shape; at lower temperatures it may become brittle.

Lambda* Roller Chain

'LAMBDA'* Roller Chains do not require additional lubrication making them ideal for applications where lubrication could affect the product on line. These 'Lube Free' chains are designed for long wear life.
