Airtac ACED Double-acting Compact Cylinder ACED50X120SB
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED50X120SB is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø50mm bore and 120mm stroke, 1/8" 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 ACED50X120SB
A double acting compact cylinder built to ISO 21287, the ACED50X120SB has a piston rod leaving both covers, so the 50 mm bore delivers an identical 881.2 N at 0.5 MPa and 1233.7 N at 0.7 MPa on every stroke. The hard-anodized aluminium body with an S45C hard-chrome plated 16 mm rod runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), with speeds of 30-500 mm/s. Because the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, it slots into tight fixtures where a full-length body cannot.
The through-rod resists rotation and side load and gives a symmetric mount, and the rear rod can carry a sensor flag on a packaging or assembly machine. This S-code model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be clipped onto the body slots for end-of-stroke detection. A fixed TPU bumper at each end absorbs end-of-stroke energy, and the male rod thread (B code) suits clevis or knuckle accessories.

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 ACED50X120SB Is Used
Case pusher on a carton line
The equal 881.2 N output in both directions lets one valve cycle push a carton into a transfer station and retract the tooling at the same force, with the rear rod carrying a position flag.
Symmetric part ejector in a press die
A rod on each cover ejects a stamped bracket and returns the stripper plate with identical 1233.7 N at 0.7 MPa, keeping the die face balanced at 30-500 mm/s.
Belt tensioning station
The through-rod takes side load without rotating, so the free end can tension a conveyor idler while the back rod drives a tracking sensor arm, both ends damped by fixed TPU bumpers.
Is the Airtac ACED Double-acting Compact Cylinder ACED50X120SB the Right Cylinder?
For a 120 mm stroke in this force class, the 50 mm bore gives 881.2 N both ways at 0.5 MPa; step down to a 40 mm bore (571.8 N) for lighter tooling or up to a 63 mm bore (1458.1 N) for heavier clamping. Note that a plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check if the load must be held. FA/FB flanges, LB feet, CA/CB clevises and FTC brackets bolt straight to the ISO 21287 face, and the male rod thread accepts I/Y knuckles directly.
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 ACED50X120SB FAQ
Yes. Because a rod exits both covers, both strokes use the rod-side area of the 50 mm bore: 881.2 N at 0.5 MPa and 1233.7 N at 0.7 MPa, equal in either direction. At 1.0 MPa the maximum output is 179.7 kgf. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure.
This S-code unit carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches mount in the body slots for end-of-stroke signals. FA/FB flanges, LB feet, CA/CB clevises and FTC brackets bolt to the ISO 21287 face, and the male rod thread takes I/Y knuckles. The fixed TPU bumpers only decelerate the piston at each end; they never hold a load if air is lost.
