And for the MHL2 and MHF2 series, it indicates the opening/closing stroke.
For details, refer to the "How to Order" section in the web catalog of each series. The parallel type air gripper catalogs can be found here.

The MHL2 Series finger motion is synchronized by a rack-and-pinion mechanism. The double piston construction creates a compact gripper with a large holding force. Vacuum ports, copper fluorine and silicon free options available.
