Genuine AirTAC long-stroke parallel gripper, order code HFKL25F from the HFKL range. The options this code selects are decoded below; series data follow the official AirTAC catalog.
The HFKL25F pairs the Dia 25 mm long-stroke HFKL platform with the F jaw code, bottom mounting: your fingers are secured underneath the jaws, which drops the grip point below the guide body, useful in tight vertical spaces or where the top of the jaw must stay clear. It is double acting, so air closes and opens the jaws, running on the integrated crossed-roller linear guide with 22 mm total stroke and +/-0.01 mm repeatability.
At 0.5 MPa with gripping distance L = 20 mm, one jaw closes with 69 N and opens with 102 N. The catalog lists the Dia 25 F-jaw version at 484 g against 489 g for the standard jaw, so the bottom-mounting jaw saves a few grams on the tool side. Ports are M5x0.8, pressure range is 0.15-0.7 MPa, no lubrication is required and the magnet in every unit supports CMSH/DMSH/EMSH or CMSG/DMSG/EMSG switches in the body grooves without brackets.

Order the HFKL25F when fingers must hang below the jaw, for example gripping parts under a low ceiling or over a fixture. If the fingers attach on top, use the plain HFKL25 standard jaw; for side bolts choose the HFKL25B, and for through-bolt fixing choose the HFKL25N. On bore size, the HFKL20 offers 45 N closing and 68 N opening force with 18 mm stroke if the Dia 25 closing force of 69 N exceeds what the part can tolerate, and a longer gripping distance than L = 20 mm lowers the usable force, so confirm the working point from the datasheet.
Bottom-mounted fingers reach under carton flaps or trays, and the 22 mm stroke opens wide enough to release flat packages without skimming the guides above.
With fingers below the jaw, the top face and part view stay unobstructed for cameras, while a CMSG, DMSG or EMSG switch in the square groove confirms open and closed positions.
The 484 g F-jaw version with +/-0.01 mm repeatability places connectors and covers into fixtures, with the 0.15-0.7 MPa pressure range letting you tune grip force for delicate housings.
Dia 25 mm bore, double acting, closing 69 N and opening 102 N per jaw at 0.5 MPa at gripping distance L = 20 mm, total stroke 22 mm, M5x0.8 ports, operating pressure 0.15-0.7 MPa, weight 484 g with the F jaw, repeatability +/-0.01 mm, temperature -20 to +70 C, maximum frequency 120 c.p.m.
The F code selects the bottom-mounting jaw, so fingers are fixed underneath the jaw and the grip point sits below the guide body, keeping the jaw top face free. The catalog lists 484 g for the Dia 25 F-jaw version versus 489 g for the standard jaw; forces, stroke and pressure range are unchanged across the jaw variants.
