About the Airtac HFKL Guided Parallel Type Pneumatic Gripper HFKL25N
The HFKL25N is the Dia 25 mm bore of the AirTAC HFKL long-stroke parallel gripper ordered with the N jaw option, so your fingers attach through mounting holes that pass through the jaw. At 0.5 MPa with a gripping distance of L = 20 mm, each jaw closes with 69 N and opens with 102 N, and the total jaw stroke is 22 mm, the longest in the HFKL range. The two jaws slide on an integrated crossed-roller linear guide, which is what delivers the series repeatability of plus or minus 0.01 mm at cycle rates up to 120 c.p.m.
Every HFKL25N carries a magnet, and the Dia 25 body has square and round sensor grooves that accept CMSG, DMSG or EMSG switches without brackets. Air supply runs from 0.15 to 0.7 MPa on this bore, the port thread is M5x0.8, and the unit weighs 489 g in standard jaw form. Filter the air to 40 um and no lubrication is needed.

How to choose
Pick HFKL25N when the N jaw style suits your fingers: the through-hole mounting option lets you bolt custom fingers through the jaw body, while the blank standard jaw, the B side-mounting jaw and the F bottom-mounting jaw (484 g on Dia 25) cover the other attachment geometries. Stay on Dia 25 if 69 N closing force per jaw at L = 20 mm is the requirement; Dia 20 closes at 45 N and Dia 16 at 34 N. If you need the same bore in single-acting normally closed or normally open form, the catalog points to HFSKL and HFTKL instead.
Applications
Machined-part load and unload
The 22 mm total stroke swallows size variation on turned or milled blanks, and the 69 N per-jaw closing force at L = 20 mm holds Dia 25-class steel parts securely between cycles.
Fingered tooling for light robots
Through-hole jaws let you design long custom fingers bolted straight through the jaw, while the 489 g gripper weight and crossed-roller guide keep end-of-arm mass and deflection low.
Position-verified clamping stations
Drop a CMSG, DMSG or EMSG switch into the square sensor groove on the Dia 25 body to confirm open or closed state each cycle, no bracket fabrication needed.
FAQ
What are the key figures of the AirTAC HFKL25N?
Dia 25 mm bore, double acting, closing force 69 N and opening force 102 N per jaw at 0.5 MPa (gripping distance L = 20 mm), total jaw stroke 22 mm, weight 489 g with standard jaw, operating pressure 0.15-0.7 MPa, port M5x0.8, repeatability plus or minus 0.01 mm, max frequency 120 c.p.m., temperature -20 to +70 C, air filtered by a 40 um element.
How do I mount fingers on the N version of the HFKL25?
The N option is the through-hole mounting jaw: bolt your fingers through holes that pass through the jaw, which is useful for long or stepped finger designs. The alternatives in the ordering code are the blank standard jaw, B for side mounting and F for bottom mounting. For single-acting variants of this series, see HFSKL and HFTKL.
