About the Airtac ACED Double-acting Compact Cylinder ACED20X20S
The ACED20X20S is a double acting, double-rod compact cylinder built to ISO 21287: a 20 mm bore with a 10 mm rod exiting BOTH covers, so output force is equal in both directions (117.8 N at 0.5 MPa, 164.9 N at 0.7 MPa, each way). The hard-anodized aluminium body with an S45C hard-chrome-plated rod runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, with a fixed TPU bumper at each end.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures, guards and small gantries. The through-rod resists rotation and light side load and gives a symmetric mount, and the back-end rod can carry a sensor flag. This S-coded model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches mount directly on the body slots. As a buyer rule of thumb, plan on roughly 70 N of usable work at 0.5 MPa (about 0.6 of the rating), which is around 7 kg of vertical lift with a 2:1 margin.

|---|---|
| 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 ACED20X20S Is Used
Small-part ejection from plastic molds
The 117.8 N both-ways output at 0.5 MPa pushes finished caps or bushings off a mold face, and the 20 mm stroke fits the shallow space beside the tool.
Presence checking on electronics assembly lines
With the fitted -S magnet and CMSE or DMSE switches, the through-rod probes PCB trays and confirms component seating at 30-500 mm/s.
Reciprocating guide rails on packaging machines
A rod on each cover lets the back rod drive a guide or carry a flag while the front rod does the work, giving equal 164.9 N force at 0.7 MPa in both directions.
Is the Airtac ACED Double-acting Compact Cylinder ACED20X20S the Right Cylinder?
For this 20 mm bore the 117.8 N per-direction output suits light clamping, part present/absent checks and small transfer heads; step down to the 16 mm bore (75.4 N at 0.5 MPa) for lighter loads or up to the 25 mm bore (206.2 N) when you need roughly 75% more force in the same compact family. Stroke 20 mm is well inside the 100 mm max standard stroke for this bore. Remember the piston drifts if air is lost - add a rod lock or pilot check where a load must be held. 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 lets you add CMSE / DMSE switches for end-of-stroke signalling.
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 ACED20X20S FAQ
Because a 10 mm rod exits both covers, both strokes use the rod-side area, so force is equal both ways: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa in each 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, port M5x0.8, female rod thread M6x1.0.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits tight jigs and guards. The S in ACED20X20S means the optional -S magnet is fitted, so CMSE / DMSE reed or solid-state switches can be mounted in the body slots; a fixed TPU bumper at each end absorbs end-of-stroke energy, and FA/FB flange, LB foot and FTC brackets bolt straight to the standard face.
