Airtac ACED Double-acting Compact Cylinder ACED20X25SB
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED20X25SB is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø20mm bore and 25mm stroke, M5×0.8 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 ACED20X25SB
A double acting compact cylinder with a rod leaving both covers, the ACED20X25SB delivers 117.8 N at 0.5 MPa in either direction because both strokes work on the rod-side area. The 20 mm bore and 25 mm stroke suit short, symmetric moves where a plain cylinder would cant or twist. Its male rod thread (the B code) bolts straight to tooling, and the PT port is M5x0.8.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures and guarding. The hard-anodized aluminium body carries a S45C hard-chrome plated rod, a fixed TPU bumper sits at each end, and the fitted -S magnet accepts CMSE / DMSE switches for end-position sensing. Running on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), it cycles at 30-500 mm/s. As a rule of thumb, plan on roughly 70 N of usable push at 0.5 MPa, and for vertical work expect it to lift about 6 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 (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 ACED20X25SB Is Used
Pick-and-place on small assembly cells
The symmetric through-rod keeps a gripper square over a 25 mm transfer between two fixture nests, with the -S magnet and a CMSE switch confirming both end positions.
Sample press in laboratory automation
A 117.8 N clamping force at 0.5 MPa seats vials or microplates under a lid, and the short body fits inside a compact benchtop enclosure.
Product diverter on packaging lines
Pushing cartons sideways on a narrow conveyor, the double-rod build resists the side load, and the male rod thread takes a custom pusher plate directly.
Is the Airtac ACED Double-acting Compact Cylinder ACED20X25SB the Right Cylinder?
Size down to the ACED16X25SB (75.4 N at 0.5 MPa) if the load is light, or step up to the ACED25X25SB (206.2 N at 0.5 MPa) for heavier tooling. The through-rod resists rotation and side load, and the rear rod can carry a sensor flag. Note that the piston will drift if air is lost, so add a rod lock or pilot check where a load must be held. FA/FB flange, LB foot, CA/CB clevis and FTC brackets, plus I/Y rod knuckles, bolt to the ISO 21287 face.
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 ACED20X25SB FAQ
At 0.5 MPa it develops 117.8 N, and at 0.7 MPa it reaches 164.9 N, identical in both directions because the double-rod piston works on the rod-side area each way. At the full 1.0 MPa rating the maximum output is 24.0 kgf. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure.
The S in the code means the optional -S magnet is fitted, so CMSE or DMSE reed or solid-state switches can be clipped to the body slots for end-of-stroke detection. FA/FB flange, LB foot, CA/CB clevis and FTC brackets plus I/Y knuckles mount on the ISO 21287 face, and the fixed TPU bumper at each end absorbs end-of-stroke shock.
