Airtac ACED Double-acting Compact Cylinder ACED20X5SB
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED20X5SB 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 ACED20X5SB
Double acting with a rod leaving both covers, the ACED20X5SB pushes and pulls with identical force because each stroke works on the rod-side area: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa in either direction. The 5 mm stroke suits tiny indexing and clamping moves, and the through-rod resists rotation while the rear rod end can carry a sensor flag. A fixed TPU bumper at each end absorbs end-of-stroke shock.
This is an ISO 21287 compact build: the hard-anodized aluminium body is about 50% shorter in mounting length than an ISO 15552 profile cylinder, so it slots into cramped fixtures and guarding. The S45C hard-chrome rod and grease-storing piston seal keep friction low at 30-500 mm/s. Because the -S magnet is fitted, CMSE or DMSE switches mount directly in the body slots. As a planning figure, treat roughly 70 N as the practical work output at 0.5 MPa, which corresponds to lifting about 6 kg vertically 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 ACED20X5SB Is Used
Micro ejection in PCB test fixtures
The 5 mm stroke and equal 117.8 N force both ways make this a clean fit for nudging boards off test pins, where the through-rod keeps the tooling square.
Position-flagged gate on a small assembly cell
With the -S magnet fitted, a DMSE switch on the body confirms end positions of a 5 mm gate or divert move at up to 500 mm/s.
Compact lid-press on a lab sample carousel
About 70 N of practical force at 0.5 MPa presses snap-fit sample lids, and the short ISO 21287 body fits under the carousel guard where a longer cylinder cannot.
Is the Airtac ACED Double-acting Compact Cylinder ACED20X5SB the Right Cylinder?
At 20 mm bore you sit between the 16 mm size (75.4 N at 0.5 MPa) and the 25 mm size (206.2 N at 0.5 MPa); pick down for light pick-and-place, up once loads pass about 70 N of real work. Note that a plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check if the 5 mm position must hold. The male rod thread (B code) suits direct coupling to tooling, and the -S magnet already on board means CMSE / DMSE switches can be fitted without reordering.
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 ACED20X5SB FAQ
Yes. Because a rod exits both covers, both strokes use the rod-side area: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa in either direction, with a maximum of 24.0 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the port is M5x0.8.
The ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so the 5 mm stroke unit tucks into shallow fixtures. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches clamp into the body slots for end-position feedback. A fixed TPU bumper at each end absorbs end-of-stroke energy, and FA/FB flange, LB foot or FTC brackets bolt to the standard face.
