They're actually called actuators
... and the normal ones you see on FIRST robots are called linear actuators.
The cylinder is the outer Cylindrical portion of the linear actuator.
The piston is the moving parts (moving seal, also called piston head, and the rod)
Bimba uses pressed in (press fit) end caps to seal each end to the cylinder, rubber seals to seal the rod to endcap and moving seal (aluminum disk with rubber o-ring). Because of this setup you should never allow the moving seal to slam against the endcap as it will eventually unseat the end cap (possibly with catastropic results).
Bimba also supplies rotory actuators to FIRST teams, which is essentially 2 linear actuators and a rack and pinion system.
