Why The Casting Chains Have Theoretical Pitch And Actual Pitch?

Our leading casting chains are CC600, 907E-51 and 4103 chain.

The casting process determines the rough surface of the casting.

It must be increase the gap between the pin and cast link to ensure the free rotation.

The large gap causes the chain to elongate, which makes the casting chain have the theoretical pitch and the actual pitch.
