Airtac ACED Double-acting Compact Cylinder ACED125X80SB
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X80SB is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø125mm bore and 80mm 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 ACED125X80SB
A double acting, double-rod compact cylinder built to ISO 21287, the ACED125X80SB pushes and pulls with identical force because a 25 mm rod exits both covers and each stroke works on the rod-side area. At 0.5 MPa that is 5890.5 N in either direction, rising to 8246.7 N at 0.7 MPa, so one unit can drive a heavy clamp or press head without reversing its rating. The B code gives a male rod thread on both ends, and the PT port is 1/4".
The short hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters when a 300-ton-class press frame or a gantry guard leaves no room for a full-length barrel. A fixed TPU bumper at each end absorbs end-of-stroke shock, and the through-rod resists rotation so the far rod can carry a sensor flag. This -S model carries the optional magnet, so CMSE / DMSE switches mount directly on the body slots. As a rule of thumb, plan on roughly 3534 N of usable work at 0.5 MPa, which lifts about 360 kg vertically - or 180 kg with a 2:1 margin.

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 (Ø125mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 5890 N |
| 0.7 MPa | 8247 N |
| Max (@1.0 MPa) | 1201 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 ACED125X80SB Is Used
Bale compactor ram
The 5890.5 N stroke in both directions ejects compressed scrap bales from a recycling press chamber, with the rear rod driving a position flag for the PLC.
Pallet pusher on a stretch wrapper
Equal 8246.7 N force at 0.7 MPa squares pallet loads from either side of the conveyor, and the 80 mm stroke clears the wrapper ring in a tight frame.
Die cart locators in a stamping shop
Through-rods lock die carts into the press bolster from both ends of the slide, with CMSE switches on the -S magnet confirming full seat before clamp.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X80SB the Right Cylinder?
At this bore size the ACED125X80SB sits near the top of the range: the next step down, ACED100X80SB, delivers 3769.9 N at 0.5 MPa, while there is no larger bore than 125 mm, so if you need more than 5890.5 N per direction you must move to a different cylinder family. Remember the piston drifts when air is lost - for a held vertical load add a rod lock or pilot check valve. FA/FB flanges, LB feet and FTC brackets bolt to the ISO 21287 face, and I/Y rod knuckles suit the male thread. Max standard stroke for bore 125 is 300 mm, so 80 mm is comfortably standard.
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 ACED125X80SB FAQ
Yes - the double-rod design means both strokes use the rod-side area, so force is equal either way: 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa in both directions, with a maximum of 1201.3 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, and the 1/4" PT port serves both chambers.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so a 125 mm bore fits where a full-length barrel cannot. This model carries the optional -S magnet, so CMSE or DMSE reed or solid-state switches clip into the body slots for end-of-stroke and mid-stroke signals. A fixed TPU bumper at each end absorbs end-of-stroke shock, FA/FB flange, LB foot and FTC brackets mount on the standard face, and the male rod thread (B code) suits I/Y knuckles.
