What Ansi Size Is Bicycle Chain

However the tooth shape is different.

What ansi size is bicycle chain.

The outer plates of an iso chain are taken from the chain size one level above the application requirements. Both types of bicycle chain have a pitch of 1 2 inch ansi standard 40. Many roller chains are available in multi strands and we ve included charts to cover single strand thru quadruple strand. This led to bulkier heavier chain with a longer fatigue life that is still used today.

Single speed bicycle chain is wider having a width of 1 8 inch. Sprockets come in a wide range of tooth counts for each ansi chain size. Iso standard r606 only includes single double and triple strand sprockets. In stock and ready to ship.

Below are roller chain size charts for ansi heavy series metric agricultural conveyor non standard chains. And is standard 606 metric 8 where the 8 indicates the pitch in sixteenths of an inch. Figure 1 17 bushingless bicycle chain components. Although every type of bicycle chain and freewheel have a 1 2 in pitch the width of chain varies quite a bit from 3 32 to 1 8.

This measurement indicates the length of the links. Below is a sprocket diameter chart we ve put together to help you identify the sprocket diameter you need based on the chain size and tooth count. The chain in use on modern bicycles has a 1 2 inch 12 7 mm pitch which is the distance from one pin center to another ansi standard 40 where the 4 in 40 indicates the pitch of the chain in eighths of an inch. This is especially true for the sprockets for 1 2 3 3 32 chains.

The diameters listed in our chart is the outside diameter of the sprocket tip of the sprocket tooth. Roller chain has been around for a long time and has evolved into a broad range of styles sizes. The first digit s indicate the pitch of the chain in eighths of an inch with the last digit being 0 for standard chain 1 for lightweight chain and 5 for bushed chain with no rollers. Roller chain is made in several sizes the most common american national standards institute ansi standards being 40 50 60 and 80.
