Genuine AirTAC long-stroke parallel gripper, order code HFKL25B from the HFKL range. The options this code selects are decoded below; series data follow the official AirTAC catalog.
The HFKL25B keeps the Dia 25 mm long-stroke platform of the HFKL series, double acting on an integrated crossed-roller linear guide, but the B jaw code means side mounting: your fingers bolt onto the side faces of the jaws instead of the front. The stroke is unchanged at 22 mm total, and at 0.5 MPa with gripping distance L = 20 mm one jaw closes with 69 N and opens with 102 N.
Side-mounted fingers leave the front face of each jaw free, which helps when a sensor, workstop or part feature occupies the gripping axis. Ports are M5x0.8, pressure range is 0.15-0.7 MPa and lubrication is not required. The body mounts from the side, the front (tapped or through holes) or the rear, with locating pins under the guide and a locating hole for repeatable mounting. The built-in magnet drives CMSH/DMSH/EMSH or CMSG/DMSG/EMSG switches in the body grooves, and the Dia 25 unit weighs 489 g.

Choose the HFKL25B when your finger design bolts to the side of the jaw, freeing the front face for stops, sensors or the part itself. If standard top-face finger attachment is enough, order the HFKL25 with no jaw code; if you need fingers fixed underneath, the HFKL25F (bottom mounting) is the sibling, and the HFKL25N (through-hole mounting) suits fingers secured by through bolts. The bore-side alternative is the HFKL20 with 45 N closing and 68 N opening force and 18 mm stroke if Dia 25 is more force than the application needs.
Side-mounted fingers can grip bar or blank stock low and flat between jaw and chuck, using the 22 mm stroke to clear the workholder on each load cycle at up to 120 c.p.m.
With the finger screws on the jaw sides, fixtures and probes stay clear of the front gripping axis, and the +/-0.01 mm repeatability of the crossed-roller guide keeps samples on station.
The 69 N closing force per jaw at 0.5 MPa handles boxed or trayed components, while the long stroke opens the jaws wide enough to release parts between tote dividers.
It selects the side-mounting jaw from the HFKL ordering table: blank = standard jaw, B = side mounting, N = through-hole mounting, F = bottom mounting. On the HFKL25B your fingers attach to the jaw sides; bore, forces, 22 mm stroke and 489 g weight are the same Dia 25 platform in every jaw variant.
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 489 g, repeatability +/-0.01 mm, temperature -20 to +70 C, maximum frequency 120 c.p.m.
