Airtac ACED Double-acting Compact Cylinder ACED125X45SB
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X45SB is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø125mm bore and 45mm stroke, 1/4" air ports and a hard-anodized aluminium body.

About the Airtac ACED Double-acting Compact Cylinder ACED125X45SB
A double acting, double-rod ISO 21287 compact cylinder, the ACED125X45SB pushes a 125 mm piston through a 45 mm stroke with a rod leaving both covers. Because each side sees the rod-side area, output is 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa in either direction - there is no weaker pull stroke. The male rod thread (B code) suits couplers and knuckle joints, and the 1/4" PT ports feed air filtered to 40 um.
The short hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into heavy presses and gantries where a full-length body cannot. The through-rod resists rotation and side load and can carry a sensor flag at the rear cover. As a planning figure, keep real work to roughly 3534 N (0.6 of the 0.5 MPa rating), which is about 300 kg lifted vertically with a 2:1 margin. This model carries the optional -S magnet, so CMSE / DMSE switches mount along the body slots. A fixed TPU bumper sits at both ends, speed spans 30-500 mm/s, and pressure runs 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof.

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 ACED125X45SB Is Used
Baling and compaction press
The 5890.5 N stroke from both rod ends crushes scrap or packaging bales in a short-stroke press head, with the rear rod driving a return plate or ejector.
Pallet clamp fixture
Equal 8246.7 N clamping at 0.7 MPa grips palletized loads from a symmetric double-rod mount, and the through-rod keeps the clamp plate square under side load.
Die cart lift assist
With about 300 kg of vertical lift capacity at a 2:1 margin, the 45 mm stroke nudges heavy die carts onto rails, while CMSE switches confirm seat position.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X45SB the Right Cylinder?
At 5890.5 N per direction this is near the top of the ACED range; if your load needs less than 3769.9 N at 0.5 MPa, the 100 mm bore covers it, while the 125 mm is the largest compact bore offered. The 45 mm stroke sits well inside the 300 mm maximum standard stroke for this bore, so no made-to-order length is needed. Remember the piston drifts if air is lost - add a rod lock or pilot check valve to hold a vertical load. FA/FB flange, LB foot and FTC brackets plus I/Y rod knuckles bolt to the ISO 21287 face, and the -S magnet on this unit lets CMSE / DMSE switches report end positions.
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 ACED125X45SB FAQ
Output is identical both ways because a rod exits each cover and both strokes use the rod-side area: 5890.5 N at 0.5 MPa, 8246.7 N at 0.7 MPa, and up to 1201.3 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof, speed 30-500 mm/s, and the 1/4" PT ports take air filtered to 40 um.
It is an ISO 21287 compact cylinder whose hard-anodized aluminium body is about 50% shorter in mounting length than an ISO 15552 profile cylinder, with an S45C hard-chrome 25 mm rod and a fixed TPU bumper at each end that only decelerates the stroke. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches clip into the body slots; FA/FB flange, LB foot and FTC mounts bolt straight to the standard face.
