Airtac ACED Double-acting Compact Cylinder ACED20X50B
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED20X50B 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 ACED20X50B
A double acting compact cylinder with a rod leaving both covers, the ACED20X50B delivers 117.8 N in each direction at 0.5 MPa because both strokes work on the rod-side area. The 20 mm bore takes an M5x0.8 port, the 10 mm rod ends in a male thread (the B code), and a fixed TPU bumper at each end absorbs the stroke's arrival. Its ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures and guarded cells.
Because the through-rod exits both covers, it resists rotation and light side load, and the rear rod can carry a sensor flag or a second tooling plate. Plan on roughly 70 N of usable work at 0.5 MPa, and for vertical duty expect it to lift about 6 kg with a 2:1 margin. The hard-anodized aluminium body pairs with an S45C hard-chrome rod, running 30-500 mm/s on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi). Note there is no magnet fitted on this code; order the -S variant if you need CMSE / DMSE switch positions.

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 ACED20X50B Is Used
Symmetric ejection in a small jig
The equal 117.8 N push and pull at 0.5 MPa lets one cylinder eject and retract a part nest with identical force, ideal for compact inspection fixtures.
Counterbalanced slide guidance
A rod on each cover of the 20 mm bore supports a light slide from both sides, resisting rotation on a 50 mm travel pick-and-place axis.
Flag carrier on a test bench
With the -S magnet ordered, CMSE / DMSE switches track position while the rear rod drives a sensor flag across a lab fixture.
Is the Airtac ACED Double-acting Compact Cylinder ACED20X50B 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 jig needs more than about 70 N of real work. The 50 mm stroke is well inside the 100 mm maximum standard stroke for bore 20. The male rod thread suits direct tooling attachment; FA/FB flanges, LB feet and FTC brackets bolt to the ISO 21287 face, and I/Y knuckles complete the family. Remember the piston drifts if air is lost, so add a rod lock or pilot check for a held load, and order the -S code if CMSE / DMSE sensing is planned.
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 ACED20X50B FAQ
It is a double-rod cylinder, so output is identical both ways: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa, on the rod-side area. Peak force at 1.0 MPa is about 24 kgf. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, speed 30-500 mm/s, air filtered to 40 um, -20 to +70 C.
The ISO 21287 compact body is hard-anodized aluminium with an S45C hard-chrome rod, roughly 50% shorter in mounting length than an ISO 15552 profile cylinder. A fixed TPU bumper at each end absorbs end-of-stroke energy. FA/FB flanges, LB feet, FTC brackets and I/Y knuckles bolt straight to the face. This code has no magnet; the optional -S version accepts CMSE / DMSE switches.
