About the Airtac ACED Double-acting Compact Cylinder ACED50X20S
The ACED50X20S is a double acting, double-rod compact cylinder built to the ISO 21287 short-body format: a 50 mm bore with just 20 mm of stroke, a rod leaving both covers so the output force is identical in either direction (881.2 N at 0.5 MPa, 1233.7 N at 0.7 MPa, both ways). Because the body saves about 50% of the mounting length of an ISO 15552 profile cylinder, it slots into tight pick-and-place gantries and fixture plates where a full-length body would foul the frame.
The through-rod resists rotation and light side load and gives a symmetric mount, and the rear rod can carry a sensor flag or a second tooling plate. This S-code model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches mount directly in the body slots for end-of-stroke signalling. A fixed TPU bumper at each end absorbs end-of-stroke shock, the hard-anodized aluminium body runs on an S45C hard-chrome plated 16 mm rod, and at 0.5 MPa the rod-side force works out to roughly 529 N of practical working effort, or a vertical lift of about 45 kg 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 (Ø50mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 881 N |
| 0.7 MPa | 1234 N |
| Max (@1.0 MPa) | 180 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 ACED50X20S Is Used
Fixture clamping on CNC pallets
The 20 mm stroke clamps and releases pallet fixtures inside shallow pockets; 881.2 N per side at 0.5 MPa holds parts firmly, and the symmetric double-rod mount keeps the clamp aligned.
Bidirectional pusher on packaging lines
A rod on each cover lets one cylinder push cartons off a conveyor in either stroke direction with equal 1233.7 N force at 0.7 MPa, and CMSE switches on the fitted magnet confirm each push.
Lab slide transfer between stations
The rear rod drives a sensor flag or counterweight while the front rod moves a slide, lifting test trays of about 45 kg vertically with a 2:1 margin at 0.5 MPa.
Is the Airtac ACED Double-acting Compact Cylinder ACED50X20S the Right Cylinder?
At 50 mm bore this model delivers 881.2 N per direction at 0.5 MPa - the same pushing and pulling, thanks to the double rod. If your load is lighter, the 40 mm bore (571.8 N at 0.5 MPa) saves space; if you need more, step up to the 63 mm bore (1458.1 N at 0.5 MPa). Remember the piston drifts if air is lost, so 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 straight to the ISO 21287 face, and the fitted -S magnet accepts CMSE / DMSE switches. Air supply: 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, female M10x1.5 rod thread, 1/8" 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 ACED50X20S FAQ
Yes - the double-rod design exposes the rod-side area on both strokes, so force is equal either way: 881.2 N at 0.5 MPa, 1233.7 N at 0.7 MPa, and up to 179.7 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, with a 16 mm hard-chrome rod and M10x1.5 female thread on each end.
The compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits shallow guards and tight fixture plates. This S-code model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches clip into the body slots for position feedback. A fixed TPU bumper at each end absorbs end-of-stroke energy, and FA/FB flange, LB foot or FTC brackets bolt straight to the standard face.
