Airtac ACED Double-acting Compact Cylinder ACED20X55SB
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED20X55SB is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø20mm bore and 55mm 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 ACED20X55SB
The ACED20X55SB is a double acting, double-rod compact cylinder built to the ISO 21287 short-body format. A 10 mm hard-chrome-plated S45C rod exits BOTH covers, so the 20 mm bore delivers an identical 117.8 N at 0.5 MPa (164.9 N at 0.7 MPa) on every stroke - no push-versus-pull mismatch. The male rod thread from the B code bolts straight to your tooling, and the through-rod resists rotation and side load while the free back-end rod can carry a sensor flag or a second fixture.
Because the hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, this 55 mm stroke unit slots into tight pick-and-place gantries and fixture plates. The through-rod gives roughly 12 kgf of thrust at 0.5 MPa, so plan on lifting about 6 kg vertically with a 2:1 margin. The optional -S magnet is fitted on this model, so CMSE or DMSE switches read position out of the box, and fixed TPU bumpers at both ends absorb end-of-stroke shock at speeds from 30-500 mm/s.

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 ACED20X55SB Is Used
Fixture clamping on CNC pallets
The symmetric through-rod clamps a machined housing from both sides with 117.8 N each way, and the 55 mm stroke clears the pallet in a short envelope.
Pusher on a bottling line
Equal force in both directions lets the back rod return a rejected bottle while the front rod pushes, with the -S magnet and a CMSE switch confirming home position.
Lab sample lift station
About 6 kg of safe vertical lift at a 2:1 margin raises sample trays smoothly; the compact body fits under a benchtop guard where a profile cylinder will not.
Is the Airtac ACED Double-acting Compact Cylinder ACED20X55SB the Right Cylinder?
At 117.8 N per direction, this bore sits between the 16 mm frame (75.4 N at 0.5 MPa) and the 25 mm frame (206.2 N at 0.5 MPa) - step up if your part plus friction exceeds about 70 N of real work. The 55 mm stroke is well inside the 100 mm standard limit for bore 20, so no made-to-order build is needed. Remember that a plain double-rod cylinder drifts when air is lost; add a rod lock or pilot check if the load must stay put. Match the ISO 21287 face with FA/FB flange, LB foot or FTC brackets plus I/Y rod knuckles, and keep the -S magnet in the code if CMSE/DMSE sensing is planned.
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 ACED20X55SB FAQ
Because a rod exits both covers, force is equal in both directions: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa on every stroke, peaking at 24.0 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof, air filtered to 40 um, speed 30-500 mm/s, and the fixed TPU bumper at each end absorbs end-of-stroke shock.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits shallow guards and tight fixtures. This model carries the optional -S magnet, so CMSE or DMSE reed or solid-state switches mount in the body slots. FA/FB flanges, LB feet, FTC brackets and I/Y rod knuckles bolt to the standard face, and the male rod thread suits direct tooling attachment.
