That's an interesting piston. I would guess that it operates a roller on a shaft coaxial with it, but without the other parts it's hard to tell.

Question is on shaft or sides

Did you take it apart, or was it already disassembled?

That looks like something that would slide coaxially on the spidle shaft. But it would need a roller to operate on, and that would unbalance the spindle, so seems unlikely.
