Airtac ACED Double-acting Compact Cylinder ACED20X5B
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED20X5B is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø20mm bore and 5mm 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 ACED20X5B
The ACED20X5B 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 in each direction - both strokes work on the rod-side area, so there is no push-versus-pull difference. The male rod thread (B code) bolts straight onto tooling, and the 5 mm stroke suits short indexing moves. Air supply is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof rating.
The hard-anodized aluminium body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why this bore class fits cramped pick stations and micro presses. Plan on about 70 N of real work at 0.5 MPa (roughly 60% of the rating), which corresponds to lifting about 6 kg vertically with a 2:1 margin. A fixed TPU bumper at each end absorbs end-of-stroke shock, speed runs 30-500 mm/s, and the magnet is optional - order the -S code if you need CMSE / DMSE switch sensing.

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 ACED20X5B Is Used
Micro press-stamping of connector terminals
The 117.8 N through-rod push at 0.5 MPa crimps small terminals in electronics assembly, and the male rod thread takes a custom punch tip directly.
Short-stroke part eject on a rotary indexing table
A 5 mm stroke is enough to kick a finished bushing off its nest between indexes, with equal 164.9 N force at 0.7 MPa whichever way the table cycles.
Clamp-and-confirm fixture with end detection
The back-end rod carries a workpiece flag while the front rod clamps; order the -S code so CMSE / DMSE switches confirm both end positions.
Is the Airtac ACED Double-acting Compact Cylinder ACED20X5B the Right Cylinder?
At 117.8 N per side at 0.5 MPa, this 20 mm bore sits between the 16 mm ACED (75.4 N) and the 25 mm ACED (206.2 N), so step up to 25 mm if your fixture needs nearly double the force in the same compact envelope. The 5 mm stroke is well inside the 100 mm standard maximum for this bore. Note that a plain double-rod cylinder will drift if air is lost - add a rod lock or pilot check valve for held loads. Mounting brackets (FA/FB flange, LB foot, FTC) plus I/Y rod knuckles bolt to the ISO 21287 face, and the optional -S magnet enables CMSE / DMSE switches; without -S no magnet is fitted.
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 ACED20X5B FAQ
Yes - because a rod exits both covers, both strokes use the rod-side area. Output is 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa, equal in each direction, with a maximum of 24 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and the 5 mm stroke is a standard length for the 20 mm bore (max standard 100 mm).
It follows the ISO 21287 short-body format: the hard-anodized aluminium body is about 50% shorter in mounting length than an ISO 15552 profile cylinder, so it slots into tight jigs and gantries. A fixed TPU bumper at each end absorbs end-of-stroke impact. Position sensing needs the optional -S magnet - order ACED20X5BS and CMSE / DMSE switches can be mounted in the body slots; without -S there is no magnet.
