Airtac ACED Double-acting Compact Cylinder ACED20X45S
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED20X45S is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø20mm bore and 45mm 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 ACED20X45S
The ACED20X45S 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 piston resists rotation and side load and the output force is equal in both directions - 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa on every stroke, because both sides work on the rod-side area. The 45 mm stroke sits well inside the 100 mm maximum standard stroke for this bore, and the M5x08 ports take air filtered to 40 um at 0.15-1.0 MPa (22-145 psi).
The hard-anodized aluminium body with threaded aluminium covers saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs, guards and gantries. A fixed TPU bumper at each end absorbs end-of-stroke energy, speed spans 30-500 mm/s, and the fitted -S magnet lets you add CMSE or DMSE reed or solid-state switches for position feedback. In practice, plan on roughly 70 N of usable work at 0.5 MPa, which is about 7 kg of vertical lift 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 ACED20X45S Is Used
Pick-and-place on PCB test rigs
The equal 117.8 N force both ways and symmetric through-rod mount suit small vertical lift-and-lower heads, lifting roughly 6 kg with a 2:1 margin, while the short ISO 21287 body fits under low gantry frames.
Position-verified clamping in assembly jigs
The fitted -S magnet accepts CMSE or DMSE switches so the PLC confirms the 45 mm clamp stroke is complete on every cycle of an electronics or small-parts fixture.
Back-to-back push-pull stations
With a rod at each cover, the rear rod can carry a tool or sensor flag while the front rod drives the workpiece - ideal for compact test stations needing identical force in both directions.
Is the Airtac ACED Double-acting Compact Cylinder ACED20X45S the Right Cylinder?
At 117.8 N per direction this bore sits between the 16 mm size (75.4 N at 0.5 MPa) and the 25 mm size (206.2 N at 0.5 MPa), so step up if your tooling needs more than about 70 N of real work. Remember the piston drifts when air is lost - for a held load add a rod lock or pilot check valve. FA/FB flange, LB foot and FTC brackets plus I/Y rod knuckles bolt straight to the ISO 21287 face, and the fitted -S magnet pairs with CMSE / DMSE switches. Female M6x1.0 rod thread, PT ports.
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 ACED20X45S FAQ
Yes - the double-rod design means both strokes use the rod-side area, so output is equal either way: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa, 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 bore is 20 mm with a 45 mm stroke and M5x0.8 ports.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body and fixed TPU bumpers at both ends. This model carries the optional -S magnet, so CMSE or DMSE reed or solid-state switches can be clipped onto the body slot for end-of-stroke or mid-stroke detection. FA/FB flange, LB foot and FTC mounting plus I/Y rod knuckles attach directly to the standard face.
