Airtac ACED Double-acting Compact Cylinder ACED80X70
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED80X70 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 ACED80X70
A double acting compact cylinder built to ISO 21287, the ACED80X70 pushes a 20 mm rod out of BOTH covers, so its 80 mm bore delivers 2356.2 N at 0.5 MPa and 3298.7 N at 0.7 MPa in either direction - both strokes work on the rod-side area. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight gantries and guarded stations where a full-length body will not fit.
In practice, plan on roughly 1414 N of real work at 0.5 MPa (about 60% of the rating), which corresponds to lifting about 120 kg vertically with a 2:1 margin. The through-rod resists rotation and side load and gives a symmetric mount, and the rear rod can carry a sensor flag. A fixed TPU bumper at each end absorbs end-of-stroke energy, and the hard-anodized aluminium body with an S45C hard-chrome-plated rod runs at 30-500 mm/s on air filtered to 40 um.

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 ACED80X70 Is Used
Symmetric press-fit station
The equal 2356.2 N force in both directions lets one ACED80X70 press a bearing into a housing on the forward stroke and eject the finished part on the return, with the 70 mm stroke matching a typical fixture depth.
Pallet lift-and-lower module
With about 120 kg of vertical lift capacity at a 2:1 margin, the 80 mm double rod carries a small pallet elevator in a packaging line, the second rod keeping the carriage guided and rotation-free.
Reciprocating conveyor pusher
A rod on each cover drives a bidirectional pusher arm that indexes cartons across a conveyor at 30-500 mm/s, the through-rod handling the side load of the product stream.
Is the Airtac ACED Double-acting Compact Cylinder ACED80X70 the Right Cylinder?
At 80 mm bore this sits between the 63 mm size (1458.1 N at 0.5 MPa) and the 100 mm size (3769.9 N at 0.5 MPa), so choose it when a 63 mm unit is under-powered but a 100 mm body is too large for the station. Remember it is a plain double-rod cylinder: if the load must stay put when air is lost, add a rod lock or pilot check valve. FA/FB flanges, LB foot and FTC brackets plus I and Y rod knuckles bolt straight to the ISO 21287 face; for CMSE or DMSE switch position feedback, order the optional -S magnet version, since this standard code ships without a magnet.
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 ACED80X70 FAQ
Because a rod exits both covers, force is equal in both directions: 2356.2 N at 0.5 MPa and 3298.7 N at 0.7 MPa, with a maximum of 480.5 kgf at 1.0 MPa. A practical rule of thumb is about 60% of the 0.5 MPa figure for real work, roughly 1414 N, which lifts about 120 kg vertically with a 2:1 safety margin. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and a fixed TPU bumper at each end absorbs end-of-stroke energy. FA/FB flange, LB foot and FTC brackets plus I/Y rod knuckles mount directly on the standard face. For CMSE or DMSE switch feedback you must order the optional -S magnet code; this standard ACED80X70 has no magnet fitted, so no sensor can be mounted on it.
