How To Measure Roller Chain Size?
To measure a roller chain correctly, identify key dimensions such as chain pitch, roller diameter, and inner width. These measurements help determine the chain size and ensure proper matching with chain sprockets.
The most important dimension is the pitch, which is the distance between the centers of two adjacent pins.
| Dimension | Description | Purpose |
| Pitch | Distance between pin centers | Determines chain size |
| Roller Diameter | Diameter of the roller | Affects sprocket fit |
| Inner Width | Width between inner plates | Ensure proper engagement |
You can measure the chain by selecting a section and using a caliper or ruler to check the distance between pin centers. For better accuracy, it is recommended to measure across multiple chain pitches and divide by the number of links.
Other important dimensions include the roller diameter and the inner width between inner plates, which are used to confirm compatibility with sprockets and applications.
If you are unsure about the roller chain size, you can also provide photos, drawings, or samples, and we can assist in identifying the correct specification.
