Airtac ACED Double-acting Compact Cylinder ACED80X20SB
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED80X20SB is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø80mm bore and 20mm 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 ACED80X20SB
A double acting ISO 21287 compact cylinder with a rod leaving both covers, the ACED80X20SB delivers 2356.2 N in each direction at 0.5 MPa because both strokes work on the rod-side area. The 80 mm bore and short 20 mm stroke suit tight clamping stations where a full-length body would never fit: the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder. A fixed TPU bumper sits at each end to absorb end-of-stroke impact.
The through-rod resists rotation and side load, and the rear rod can carry a sensor flag on a transfer or press fixture. This -S version carries the optional magnet, so CMSE / DMSE reed or solid-state switches mount directly in the body slots. At 0.5 MPa the thrust equals about 240 kg, so plan on lifting roughly 120 kg vertically with a 2:1 margin, or use about 1414 N for real work. Ports are 1/4" PT, pressure runs 0.15-1.0 MPa (22-145 psi), and speed spans 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 ACED80X20SB Is Used
Press-fit stamping station
The 2356.2 N symmetric thrust presses bearings or bushings into housings on an assembly line, with the 20 mm stroke matching short press-fit travel.
Conveyor gate diverter
Equal force both directions throws product between conveyor lanes, and the rear rod carries a flag read by a CMSE switch to confirm gate position.
CNC fixture clamp
Mounted under a machining-centre jig, the through-rod clamps a workpiece from both sides without rotating under 1414 N of usable clamping load.
Is the Airtac ACED Double-acting Compact Cylinder ACED80X20SB the Right Cylinder?
Size both ways: an ACED50X20 gives 881.2 N at 0.5 MPa, while the next step up, ACED100X20, reaches 3769.9 N. Choose this 80 mm bore when your fixture needs roughly 1400 N of usable work force. Note that a plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check if the load must stay held. FA/FB flange, LB foot and FTC brackets plus I/Y rod knuckles bolt to the ISO 21287 face, and the male rod thread (B code) suits clevis-style tooling.
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 ACED80X20SB FAQ
Yes. Because a rod exits both covers, both strokes use the rod-side area: 2356.2 N at 0.5 MPa and 3298.7 N at 0.7 MPa, equal in push and pull. At 1.0 MPa the maximum output is 480.5 kgf. Operating pressure is 0.15-1.0 MPa (22-145 psi) with 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, so it fits shallow fixtures and guards. The S in ACED80X20SB means the magnet option is fitted, so CMSE / DMSE switches can be slid into the body slots for end-of-stroke sensing. The fixed TPU bumpers at both ends absorb impact but never hold a load when air is lost.
