How To Measure Roller Chains?

Apr 16,2024

Roller Chains Measurement


Measuring a roller chain might seem like a small task, but it can make a big difference in your machinery's performance. Accurate measurements are essential whether you're maintaining industrial equipment or replacing an old roller chain. Poorly measured roller chains can lead to inefficiency, wear, and even safety hazards. So, if you've ever wondered how to measure roller chains properly, you're in the right place.

Roller Chains Measure Tools


Essential Roller Chain Measure Tools

• A reliable ruler or measuring tape
• A caliper for precise measurements
• Pen and paper (to jot down measurements)

Optional Roller Chain Measure Tools For Greater Precision

• A digital caliper for finer measurements
• A chain wear gauge to check for elongation
• A magnifier to inspect worn areas closely

Step-by-Step Guide to Measuring a Roller Chain

Measuring Roller Chain Pitch

Pitch refers to the distance from the center of one pin to the center of the next pin on the roller chain.

Measuring Roller Chain Side Plate Height

The roller chain side plate height refers to the height of the chain plates, which can be measured either on the inside or outside of the chain.

Measuring Roller Chain Side Plate Thickness

The plate thickness is crucial to measure accurately. It's recommended to measure both the inside and outside plate thicknesses, as some ISO and DIN metric roller chains may feature plates with different thicknesses.

Measuring Roller Chain Roller Diameter

The pin diameter is a crucial measurement when assessing roller chains. It's essential because some specialty roller chains may feature non-standard pin diameters.

Measuring Roller Chain Roller Width

The roller width is a significant measurement for roller chains. In the case of roller-less chains, measuring the inside width of the inner side plates provides the necessary dimension.

Measuring Roller Chain Overall Chain Width

The overall width of the roller chain is a critical dimension to consider. When measuring, it's important to exclude the overall width of the master link or offset link, focusing solely on the width of the chain itself.

Roller Chains Standard

ANSI Standard Roller Chain

ANSI roller chains are widely used in North America and adhere to strict measurement criteria.
ANSI roller chains follow American standards, measured in inches. Common in North America, they are strong and widely used in industrial and agricultural machinery.

British(ISO/DIN) Standard Roller Chain

British(ISO/DIN) standard roller chains, also called metric roller chains are internationally recognized and commonly used in global markets.
Metric roller chains, measured in millimeters, follow international standards. Popular in Europe, they are used in industries requiring global metric compatibility.

Tips For Accurate Roller Chain Measurements

How to Avoid Common Errors

Always clean the roller chain before measuring to remove debris or grease and use the proper tools to prevent inaccurate readings.

Handing Worn or Stretched Roller Chains

Stretched roller chains may give false roller chain pitch measurements. Use roller chain wear gauge for more reliability.

When To Replace Roller Chains

Look for elongation, stiff links, or uneven wear.

Roller Chain Measurement Tolerance for Replacement

Replace the roller chain if elongation exceeds 2-3% of its original length.

Common Roller Chains Measurement Mistake

Overlooking Roller Chain Stretch

Roller chain elongation can lead to misalignment and increased wear.

Using the Wrong Roller Chain Measurement Tools

Using a standard ruler for precise measurements can result in errors.

Roller Chains FAQs

What’s the difference between measuring chain pitch and length?
The roller chain pitch measures the distance between two pins, while the length is the overall measurement of the roller chain.
How often should I measure my roller chain?
Inspect and measure your roller chain every 3-6 months, depending on usage.
Can reuse a stretched roller chain?
No, stretched roller chains can compromise performance and should be replaced.
