Is there a difference between the type A chain and the type B sprocket paired?

 

The A-type and B-type chains have the same pitch, but the B-type rollers have a larger diameter and are made thicker, so the B-type chain has a higher tensile strength. But the sprocket type B should be thinner, the radius of the roller should be larger, and relatively weaker.
