Airtac ACED Double-acting Compact Cylinder ACED20X45
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED20X45 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 ACED20X45
The ACED20X45 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 thrust is identical on each stroke - 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa - because both sides work on the rod-side area. The through-rod also resists rotation and side load, and the free rear rod end is a handy spot for a sensor flag or a second tooling point.
With a 20 mm bore the body is short enough for tight slides and pick stations: it saves about 50% of the mounting length of an ISO 15552 profile cylinder. The hard-anodized aluminium barrel carries M5x0.8 ports, and fixed TPU bumpers at each end absorb end-of-stroke shock. As a working figure, plan on roughly 70 N (about 7 kgf) of usable push at 0.5 MPa, which corresponds to lifting about 6 kg vertically with a 2:1 margin. Speed range is 30-500 mm/s over 0.15-1.0 MPa (22-145 psi).

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 ACED20X45 Is Used
Small-part ejection from press dies
The symmetric 117.8 N push and pull at 0.5 MPa clears finished 6 kg-class parts from a stamping die, and the short ISO 21287 body slots between die plates where a full-length cylinder cannot.
Bidirectional reject pusher on a bottling line
Equal force both ways means the same 164.9 N at 0.7 MPa rejects underfilled bottles whether the rod travels in or out, at line speeds up to 500 mm/s.
Sample lift in a compact lab analyzer
The rear rod end carries a position flag while the front rod raises about 6 kg of sample tray vertically with a 2:1 margin inside a tight instrument enclosure.
Is the Airtac ACED Double-acting Compact Cylinder ACED20X45 the Right Cylinder?
At 117.8 N per side at 0.5 MPa, this 20 mm bore suits light clamping and small part transfer. Step down to the ACED16X45 (75.4 N) for lighter loads, or up to the ACED25X45 (206.2 N) if your jig needs more margin. The 45 mm stroke sits well inside the 100 mm maximum standard stroke for this bore. Remember the piston drifts if air is lost - add a rod lock or pilot check valve where a load must stay put. Order the -S code if you want CMSE / DMSE switch capability; without it no magnet is fitted. Female M6x1.0 rod thread and FA flange, LB foot or FTC brackets bolt straight onto 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 ACED20X45 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 each stroke, with a maximum of 24.0 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the 45 mm stroke is well within the 100 mm maximum standard stroke for a 20 mm bore.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body, S45C hard-chrome-plated 10 mm rod through both covers, M5x08 ports - written M5x0.8 - and fixed TPU bumpers at each end. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder. Switches are possible only if you order the optional -S magnet code, which enables CMSE / DMSE sensors; the base model has no magnet fitted.
