Helpful for Model Matching:
| Identity / ordering | Double-acting parallel gripper with dust-proof cover and roller-bearing guide. HFKP16/20/25/32 only; finger type blank standard. No jaw-form code or S suffix is published. |
| Working air / pressure | Air filtered by 40 μm element; 0.15–0.7 MPa; −20 to +70°C. Lubrication not required. Catalogue gives no proof-pressure rating: do not import another family rating. |
| Per-finger gripping force | At 0.5 MPa and gripping point L=20 mm: 16 closed 30/open 40 N; 20 closed 42/open 66 N; 25 closed 65/open 104 N; 32 closed 158/open 193 N. These are effective force per finger, not summed pair force or payload kg. |
| Opening / closing total stroke | Both-sides total stroke: 16 6 mm; 20 10 mm; 25 14 mm; 32 22 mm. Do not label this as single-finger travel. Match actual closed/open jaw gaps in drawings. |
| Repeatability / max frequency | 16/20/25 repeatability ±0.01 mm and max 180 cycles/min; 32 ±0.02 mm and max 60 cycles/min. Maximum frequency does not promise maximum load at every speed. |
| Mass | 16/20/25/32: 130/251/475/792 g per catalogue, not lifting payload or guaranteed packed shipping mass. |
| Force selection / friction | Choose effective force with actual pressure and L using separate closed/open curves. Safety-factor equation F > mg·a/(2μ), illustrated a=4; μ=0.2 gives 10mg, μ=0.1 gives 20mg. Acceleration/shock needs greater safety coefficient. Evaluate friction and load retention; provide anti-dropping protection where pressure loss can release the workpiece. |
| Grip point L / eccentric H | Check both L and H within the appropriate closed/open pressure-dependent curve. Long/heavy fittings add inertia and reduce life; thin/fine workpieces need gap planning to avoid loss of grip. No universal extension length or offset load. |
| External static loads / moments | 16/20/25/32 Fv: 147/221/382/514 N; Mp/My: 0.68/1.32/1.94/3 N·m; Mr: 1.36/2.65/3.88/6 N·m. These are static guide load/moment limits, not gripping-force or shock ratings. With applied moment arm L in mm, allowable force = permissible moment/(L×10⁻³). |
| Mounting / screw torques | Use own bore-specific rear/front threaded/front-through/surface mounting drawings and depth tables. Jaw-fitting bolts for16/20/25/32: M3×0.5/M4×0.7/M5×0.8/M6×1.0, max0.59/1.4/2.8/4.9 N·m. Rear mounting max2.1/4.3/7.3/7.9 N·m; threaded depths8/10/12/12 mm. Other mounting faces differ; do not reuse rear torque for jaws. |
| Installation / material boundaries | Hold gripping jaw with a spanner when tightening fittings; do not clamp body. Front through-hole mounting may obstruct internal sensor grooves. Prevent external impact with clearance at end stroke/reverse motion and coaxial workpiece insertion. Exhaust compressed air before removal. Material table is based on a certain bore; parts 25/26 only HFKP32. No IP rating, hermetic seal or universal material promise is supplied by dust-proof naming. |

No: its per-finger closing force is158 N; 193 N is the opening force. Both values apply at 0.5 MPa and L=20 mm. Use the actual pressure, gripping point and friction safety method for your workpiece.
The catalogue lists only blank standard fingers and all standard units with magnet, without a sensor. It does not publish S or another jaw-form suffix. Send the unchanged full label for confirmation.
The source gives dust-proof cover/roller-bearing construction but no IP rating or sealed-enclosure guarantee. Send your dust, fluid, temperature and service conditions for confirmation.
