CHAINWHEEL SELECTION GUIDE
There are various grades of short link chain, relating to the raw metal quality, strength and finishing process. Both galvanised and stainless steel chains are available. In order for
your windlass to retrieve and deploy the anchor and chain smoothly, without jamming, it is of great importance that the chain and chainwheel (gypsy) match. Therefore Maxwell has
devised a global chain and chainwheel spreadsheet which will help you to figure out what kind of chainwheel you need to order.

P = Pitch length inside link D = Chain wire diameter W = width outside the link L = inside dimension between 11 links.
Please take an 11 link section of your chain, lay it out in a stretched out straight line and measure the dimensions as indicated

CHAIN INFORMATION
There are various Grades of short link chain. The Grade relates to the raw metal quality, strength and finishing process. Both galvanised and stainless steel chains are available.
Chain Specification is the Standard a chain must be manufactured to in order to comply with a given International Standard.
Outside of North America the most common types of metric short link chain are DIN766 and EN-818. Within North America the most common imperial chains are BBB and G40.
The important thing to keep in mind is to select a chain grade and specification that complies with recognised standards.
In addition to the chains listed above, Maxwell can supply a variety of alternatives to meet any market demand. Please feel free to contact your nearest Maxwell dealer for assistance.
