## FAQ

### What is the pitch of a roller chain?

The pitch of a roller chain refers to the distance between the centers of adjacent roller pins, typically measured in inches (e.g., 0.5 inch pitch).

### How is roller chain size determined?

Roller chain size is determined based on the pitch, roller diameter, width between inner plates, and plate thickness of the chain.

### What does the chain size designation represent?

The chain size designation indicates the pitch and roller diameter of the chain, for example, ANSI #40 chain has a 0.5 inch pitch and 0.3125 inch roller diameter.

### What are the most common roller chain sizes?

Some of the most common roller chain sizes include ANSI #25 (0.25 inch pitch), ANSI #40 (0.5 inch pitch), and ANSI #60 (0.75 inch pitch).

### How do I identify the size of a roller chain?

To identify the size of a roller chain, check the chain for markings that indicate the pitch, roller diameter, and other relevant dimensions. You can also measure these parameters using calipers or a chain measuring tool.
