10 Easy Steps on How to Measure Chain Link Size

Step 1: Determine the Pitch

The pitch refers to the distance between two adjacent chain links. It is measured from the center of one pin to the center of another nail. The most common pitch sizes are 0.5 inches and 0.375 inches. To determine the pitch of your chain, use a ruler or caliper to measure the distance between two adjacent pins.

Step 2: Count the Number of Links

Once you’ve determined the pitch, the next step is to count the total number of links on the chain. This count should include every individual link to get an accurate total length. Lay the chain on a flat surface in a linear fashion to make counting more effortless and more precise.

Step 3: Measure Inner Diameter

Using a caliper, measure the inner diameter of a link by placing the caliper’s ends against the inner walls of the association.

If a caliper is unavailable, carefully use a ruler to gauge the inside length at the widest point of the link. This measurement is critical because it ensures that the chain will smoothly fit onto the gears without too much slack or tension.

Step 4: Measure the Roller Diameter

The roller diameter is the size of the small cylinders located inside each chain link, often referred to as rollers. These are responsible for the chain’s smooth movement on the sprocket teeth.

Place the caliper around a roller to measure its diameter, or use the edge of a ruler if a caliper is unavailable. Ensure the roller is not worn down, as this can affect the accuracy of your measurement.

Step 5: Measure the Width of the Chain

The width of the chain is the distance across the roller from one side plate to the opposite side plate. To measure this, position the caliper across two opposing inner side plates to capture the width.

If you’re using a ruler, make sure it is perfectly perpendicular to the rollers for an accurate measurement. The chain’s width is essential as it has to match the dimensions of the sprocket or cog where it will be installed.

Step 6: Check for Stretch

Chain stretch is a term used to describe the wear and elongation of a chain over time. It is not the physical stretching of the metal but rather the result of wear and tear on the pins and rollers.

To check for stretch, measure the length of a set number of links and compare it to a measurement of the same number of links on a new chain.

Significant discrepancies indicate that the chain is worn out and needs replacing. This step is vital to ensure the longevity and proper function of the machinery or bike the chain is used for.

Step 7: Record the Chain Size Specifications

With all the necessary measurements in hand, it’s crucial to record the details of your chain’s size specifications, including the pitch, number of links, inner diameter, roller diameter, and width.

Note this information on paper or in a spreadsheet for future reference. It will be invaluable when purchasing a new chain or comparing it with other chains for compatibility.

Make sure also to note the brand and model of the equipment the chain is used on, as manufacturers often provide specific sizing requirements.

Step 8: Compare with Manufacturer Specifications

Before making a final decision on purchasing a new chain, it’s prudent to compare your measurements with the specifications provided by the manufacturer. Manufacturers often offer detailed charts or guides to help users find the compatible chain size based on the equipment model or intended use.

Align the specifications you’ve recorded with those recommended by the manufacturer to ensure that your selection will operate correctly and efficiently.

Step 9: Visit a Specialist or Retailer

If you still need to decide which chain to purchase after measuring and comparing with the manufacturer’s specifications, consider visiting a bicycle shop or a machinery specialist. An expert can provide additional insight into the ideal chain for your requirements.

They can also physically inspect the current chain and equipment to offer a professional opinion. Taking the time to get a specialist’s advice could save you time and money in the long run by finding the perfect match for your setup.

Step 10: Purchase and Test the New Chain

After confirming the correct size and type of chain for your equipment, it’s time to purchase. Once you have the new chain, install it carefully, ensuring it fits properly on the gears and the tension is adjusted correctly.

Test the new chain under normal operating conditions to verify that it operates smoothly and efficiently. Regularly monitor the chain for the initial period of use to catch any issues early and ensure that your equipment is running at its best.

With these ten easy steps, you can accurately measure chain link size and confidently purchase a new chain that will fit perfectly on your equipment.
