About the Airtac ACED Double-acting Compact Cylinder ACED20X25B
The ACED20X25B is a double acting compact cylinder built to ISO 21287 with a 20 mm bore and a 25 mm stroke. Because it is a double-rod design, a 10 mm piston rod exits both covers, so the output force is equal in both directions - 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa on each stroke. The male rod thread (B code) lets you bolt tooling straight to either end, and the through-rod resists rotation while the free back rod can carry a sensor flag. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it fits tight jigs, guards and gantries.
The hard-anodized aluminium body with a roller-burnished bore runs against an S45C hard-chrome-plated rod, and a fixed TPU bumper at each end absorbs end-of-stroke energy. Speed range is 30-500 mm/s at 0.15-1.0 MPa (22-145 psi), with air filtered to 40 um and a proof pressure of 1.5 MPa (215 psi). At 0.5 MPa the 117.8 N rating works out to about 12 kg of vertical lift, so with a 2:1 margin plan on lifting roughly 6 kg. Note that this model has no magnet fitted - order the -S code if you need CMSE / DMSE switch detection.

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 (Ø20mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 118 N |
| 0.7 MPa | 165 N |
| Max (@1.0 MPa) | 24 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 ACED20X25B Is Used
Fixture clamping from both sides
The 25 mm stroke and male rod thread let a jig builder clamp a machined aluminium bracket with the front rod while the back rod drives an alignment pin - 117.8 N of clamping force in each direction at 0.5 MPa.
Push-and-pull transfer on a packaging line
A double-rod cylinder on a carton diverter pushes the box over with the front rod and retracts it with the same force, keeping the 30-500 mm/s cycle symmetric at up to 164.9 N per stroke at 0.7 MPa.
Reciprocating probe in a test rig
In a lab endurance tester the through-rod carries a load cell on one end and a counterweight on the other, so the 20 mm bore applies a balanced 117.8 N in both travel directions without rod-side force difference.
Is the Airtac ACED Double-acting Compact Cylinder ACED20X25B the Right Cylinder?
For a 25 mm stroke with equal push and pull, this 20 mm bore delivers 117.8 N both ways at 0.5 MPa. Step down to ACED16X25B (75.4 N) for lighter pick-and-place, or up to ACED25X25B (206.2 N) if the part weight grows. Remember the piston drifts when air is lost - add a rod lock or pilot check if the load must stay put. The male rod thread suits direct tooling mounts; FA/FB flange, LB foot and FTC brackets plus I/Y knuckles bolt to the ISO 21287 face, and the optional -S magnet enables CMSE / DMSE switches.
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 ACED20X25B FAQ
Yes - the double-rod design means both strokes use the rod-side area, so force is equal either way: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa. At 1.0 MPa the maximum output is 24.0 kgf. That 117.8 N equals about 12 kg of vertical lift, or roughly 6 kg with a 2:1 safety margin.
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. A fixed TPU bumper at each end absorbs end-of-stroke impact. FA/FB flange, LB foot and FTC brackets plus I/Y rod knuckles fit the standard face, and the male rod thread takes tooling directly. This version has no magnet - order the -S code to enable CMSE / DMSE switches.
