Airtac ACED Double-acting Compact Cylinder ACED20X50SB
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED20X50SB 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 ACED20X50SB
A double acting compact cylinder built to ISO 21287, the ACED20X50SB pushes a 20 mm bore through a 50 mm stroke with a rod leaving BOTH covers. Because each side sees the rod-side area, output is identical in either direction: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa, both ways. The B code gives a male rod thread, and the S code means the magnet is fitted, so CMSE or DMSE switches can be clipped on for end-of-stroke signalling.
The hard-anodized aluminium body with an S45C hard-chrome rod runs 30-500 mm/s on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi). Its short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures. As a rule of thumb, plan on roughly 70 N of usable push at 0.5 MPa, which corresponds to lifting about 6 kg vertically with a 2:1 margin. A fixed TPU bumper at each end absorbs end-of-stroke shock.

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 ACED20X50SB Is Used
Pick-and-place on small assembly cells
The symmetric through-rod gives a mounting point on both covers, letting a 6 kg-class part be guided on a jig fixture where a full-length cylinder body would not fit.
Indexed testing station with position feedback
With the magnet already fitted, CMSE or DMSE switches confirm extend and retract of a 50 mm test stroke on electronics or medical-device check fixtures.
Push-off gate on packaging conveyors
117.8 N in either direction at 0.5 MPa is enough to kick small cartons or blisters off a line, and the 30-500 mm/s speed range matches fast cycling.
Is the Airtac ACED Double-acting Compact Cylinder ACED20X50SB the Right Cylinder?
At 117.8 N per direction, this 20 mm unit sits between the 16 mm bore (75.4 N at 0.5 MPa) and the 25 mm bore (206.2 N at 0.5 MPa). If your tooling needs a back-end rod for a sensor flag or anti-rotation guidance, the through-rod here earns its keep; if you need more grip force, step up to 25 mm. Note that a plain double-rod cylinder will drift when air is lost - for a held vertical load, pair it with a rod lock or pilot check valve. FA/FB flanges, LB feet and FTC brackets bolt straight to the ISO 21287 face, and the fitted magnet works with CMSE / DMSE switches.
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 ACED20X50SB 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, extend or retract. Peak force at 1.0 MPa is about 24.0 kgf. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof rating.
It is an ISO 21287 compact cylinder whose body is about 50% shorter in mounting length than an ISO 15552 profile cylinder. The B means a male rod thread on the 10 mm rods; the S means the magnet is fitted so CMSE / DMSE switches can be mounted. A fixed TPU bumper at each end absorbs end-of-stroke energy.
