About the Airtac ACED Double-acting Compact Cylinder ACED125X120B
A double acting compact cylinder built to ISO 21287, the ACED125X120B pushes a 125 mm bore through a 120 mm stroke with a 25 mm rod leaving BOTH covers. Because each side of the piston sees the rod-side area, output is 5890.5 N at 0.5 MPa in either direction and 8246.7 N at 0.7 MPa - there is no weaker pull stroke. The male rod thread (B code) bolts straight to your tooling on both ends, and the through-rod resists rotation and side load while the rear rod can carry a sensor flag.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so this heavy thrust class still fits tight press frames and gantries. At 0.5 MPa the usable working effort is roughly 3534 N (about 0.6 of the rating), which corresponds to lifting around 300 kg vertically with a 2:1 margin. The hard-anodized aluminium body carries a roller-burnished bore, the S45C rod is hard-chrome plated, fixed TPU bumpers absorb end-of-stroke shock at both covers, and speed spans 30-500 mm/s at 0.15-1.0 MPa (22-145 psi).

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 ACED125X120B Is Used
Heavy press and forming fixtures
The 5890.5 N symmetric thrust at 0.5 MPa suits stamping, riveting and coining stations on compact press frames where a full-length profile cylinder will not fit.
Pallet and die lifting arms
With about 300 kg of vertical lift capacity at a 2:1 margin, the double rod drives scissor lifts and die-change arms with equal force up and down.
Synchronized dual-side tooling
The male-threaded rod at both covers lets one cylinder drive a clamp on the front and a sensor flag or counter-grip on the rear in packaging and machine-tool fixtures.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X120B the Right Cylinder?
For 120 mm of stroke moving multi-hundred-kilogram fixtures, the 125 mm bore delivers 5890.5 N both ways at 0.5 MPa; step down to a 100 mm bore (3769.9 N) for lighter clamping or up to a larger bore only if you exceed 8246.7 N at 0.7 MPa. Remember the piston drifts if air is lost - add a rod lock or pilot check valve where a load must stay held. Mounting is via FA/FB flange, LB foot or FTC brackets with I/Y rod knuckles on the ISO 21287 face; this unit has no magnet, so order the -S code instead if you need CMSE / DMSE switch sensing.
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 ACED125X120B FAQ
Yes - the double-rod design means both strokes use the rod-side area, so output is 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa in either direction, with a peak 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" port depends only on the 125 mm bore.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body about 50% shorter in mounting length than an ISO 15552 profile cylinder, an S45C hard-chrome rod, and fixed TPU bumpers at both ends that only decelerate the piston. This version has no magnet fitted; order the -S code to enable CMSE / DMSE switches, and use FA/FB flange, LB foot or FTC mounting with I/Y knuckles. Position is not held on air loss - fit a rod lock or pilot check for that.
