Airtac ACED Double-acting Compact Cylinder ACED20X50
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED20X50 is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø20mm bore and 50mm 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 ACED20X50
The ACED20X50 is a double acting, double-rod compact cylinder built to the ISO 21287 short-body format. A piston rod leaves both covers, so the 20 mm bore delivers an identical 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa on each stroke, because both faces work on the rod-side area. The through-rod also resists rotation and light side load, and the rear rod tip can carry a sensor flag on a fixture.
The hard-anodized aluminium body with an S45C hard-chrome rod keeps the envelope tight: it saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into slim pick-and-place heads and test rigs. A fixed TPU bumper at each end softens end-of-stroke contact, and speed runs 30-500 mm/s at 0.15-1.0 MPa (22-145 psi). For planning, treat roughly 70 N (about 7 kgf) as the usable working force at 0.5 MPa, or about 6 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 ACED20X50 Is Used
Small-part ejection from an injection mold
The symmetric 117.8 N push and pull at 0.5 MPa nudges finished nylon bushings off a core pin, and the 50 mm stroke clears the die area quickly at up to 500 mm/s.
Product pusher on a bottling line
A rod on each cover lets the back rod carry a flag while the front rod sweeps bottles sideways; the short ISO 21287 body fits between the guide rails where a full-length profile cylinder cannot.
Sample lift in a compact lab tester
With about 6 kg of vertical lift capacity at a 2:1 margin, the ACED20X50 raises specimen trays in benchtop test stations, and the fixed TPU bumpers soften each end of travel.
Is the Airtac ACED Double-acting Compact Cylinder ACED20X50 the Right Cylinder?
At 117.8 N per direction, bore 20 suits light clamping, gating and small part transfer. Step down to bore 16 (75.4 N) for tiny fixtures, or up to bore 25 (206.2 N) when a heavier clamp is needed. The 50 mm stroke sits well inside the 100 mm standard limit for this bore. Rod end is a female M6x1.0 thread and the port is M5x0.8; FA/FB flange, LB foot and FTC brackets plus I/Y rod knuckles bolt to the ISO 21287 face. Position is not held on air loss - add a rod lock or pilot check if the load must stay put. If you need CMSE or DMSE switches, order the -S code; this model without S carries no magnet.
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 ACED20X50 FAQ
Being double-rod, output is equal both ways: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa on each stroke (rod-side area both sides), with a maximum of 24.0 kgf at 1.0 MPa. Speed range is 30-500 mm/s, operating pressure 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), and the air must be filtered to 40 um. Port is M5x0.8 and the rod end is female M6x1.0.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at each end and FA/FB flange, LB foot or FTC mounting on the standard face. Sensing is optional: order the -S code to get the magnet that works with CMSE or DMSE switches. Without -S there is no magnet, so no switch can be mounted.
