Airtac ACED Double-acting Compact Cylinder ACED80X70B
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED80X70B is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø80mm bore and 70mm stroke, 1/4" air ports and a hard-anodized aluminium body. Its short compact envelope saves about 50% of the mounting length of an ISO 15552 profile cylinder.

About the Airtac ACED Double-acting Compact Cylinder ACED80X70B
A double acting compact cylinder built to ISO 21287, the ACED80X70B pushes a 20 mm rod out of BOTH covers, so the 80 mm bore delivers the same 2356.2 N at 0.5 MPa whether it extends or retracts - both strokes work on the rod-side area. At 0.7 MPa that rises to 3298.7 N in either direction, with a peak of 480.5 kgf at 1.0 MPa. The male rod thread (B code) bolts straight to your tooling.
Because the body is only about half the mounting length of an ISO 15552 profile cylinder, this 70 mm stroke unit slots into tight gantries and guarding where a full-length bore-80 cylinder will not fit. The through-rod resists rotation and side load, and the rear rod can carry a sensor flag. Plan on roughly 1414 N of usable work at 0.5 MPa - enough to lift about 144 kg vertically. The hard-anodized aluminium body carries a fixed TPU bumper at each end, and air supply is 0.15-1.0 MPa (22-145 psi) with speeds of 30-500 mm/s.

Specifications follow the official AirTAC ACE-series (ISO 21287) datasheet. Body: hard-anodized aluminium alloy; piston rod: S45C carbon steel with hard-chrome plating. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G. A built-in magnet is OPTIONAL — add the -S code to fit CMSE / DMSE position sensors.
Theoretical Output Force (Ø80mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 2356 N |
| 0.7 MPa | 3299 N |
| Max (@1.0 MPa) | 481 kgf |
Double-rod: a rod exits both covers, so output force is equal in both directions (rod-side area used).

Where the Airtac ACED Double-acting Compact Cylinder ACED80X70B Is Used
Automotive fixture clamping
The symmetric 2356.2 N force clamps steel stamping dies from both sides of a machining fixture, with the 70 mm stroke clearing part loading in tight die-change envelopes.
Push-pull conveyor gates
A packaging line diverter gate gets equal push and pull from one cylinder, with the rear rod driving a flag for a mechanical position indicator.
Press ejection slide
Ejecting formed metal panels from a stamping press bed, where the through-rod resists the side load of off-center parts and the 1/4" ports feed 30-500 mm/s cycling.
Is the Airtac ACED Double-acting Compact Cylinder ACED80X70B the Right Cylinder?
At 2356.2 N per direction at 0.5 MPa, the 80 mm bore sits between the 63 mm size (1458.1 N) and the 100 mm size (3769.9 N) - step down if your load is under 1400 N, step up if you need over 2400 N. The 70 mm stroke is well inside the 300 mm maximum standard stroke for this bore, so it ships as a catalogue item. Remember that a plain double-rod cylinder drifts when air is lost; add a rod lock or pilot check valve if the load must stay put.
This version has the male rod thread and PT ports but no magnet - order the -S code instead if you want CMSE / DMSE switch detection. FA/FB flanges, LB foot and FTC brackets plus I and Y rod knuckles mount directly on the ISO 21287 face.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Short stroke fits the compact body
- ✓ Port/thread type (PT / G)
- ✓ Add -S if you need the magnet for sensors
- ✓ Rod type (female / male B) & mount (FA/LB/CA)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Compact body: keep the stroke short and avoid side load on the rod.
- check Do not dismantle the threaded front/back covers.
- check Keep speed within the rated range; the TPU bumper absorbs stroke-end energy.
- check Installation by qualified personnel per AirTAC docs.
Airtac ACED Double-acting Compact Cylinder ACED80X70B FAQ
Yes - the double-rod design means a rod exits both covers, so both strokes use the rod-side area. Output is 2356.2 N at 0.5 MPa and 3298.7 N at 0.7 MPa, equal on extend and retract, with a maximum of 480.5 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s.
ACED80X70B has a male rod thread, PT ports (1/4" on this 80 mm bore) and fixed TPU bumpers at both ends of the hard-anodized aluminum body. It mounts via FA/FB flanges, LB foot or FTC brackets, with I and Y rod knuckles available. No magnet is fitted on this code; order the -S variant to enable CMSE / DMSE switches. The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder.
