Airtac ACED Double-acting Compact Cylinder ACED50X250SB
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED50X250SB is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø50mm bore and 250mm 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 ACED50X250SB
This is a double acting, double-rod compact cylinder built to ISO 21287: a 16 mm hard-chrome-plated S45C rod leaves BOTH covers, so the ACED50X250SB pushes with the same 881.2 N at 0.5 MPa (1233.7 N at 0.7 MPa) whichever end it works from. The 50 mm bore sits in a hard-anodized aluminium body whose short profile saves about 50% of the mounting length of an ISO 15552 profile cylinder, and the 250 mm stroke is the maximum standard stroke for this bore. The S in the code means the optional -S magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clipped onto the body slots right away.
Because the through-rod exits both covers, the piston resists rotation and tolerates side load better than a single-rod design, and the rear rod can carry a sensor flag or a second tool. A fixed TPU bumper at each end absorbs end-of-stroke shock, and the male rod thread (B code) bolts straight to external tooling. Speed range is 30-500 mm/s across 0.15-1.0 MPa (22-145 psi).

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 ACED50X250SB Is Used
Symmetric press fixture
The equal 881.2 N output in both directions lets one cylinder press a bearing in on the forward stroke and eject the finished bushing on the return, with the 250 mm stroke clearing a deep die set.
Push-pull transfer on a packaging line
A rod on each cover means the same 1233.7 N at 0.7 MPa shoves cartons into a case packer and retracts the pusher without a return spring or reversed porting, at up to 500 mm/s.
Gantry pick station with position feedback
With the fitted -S magnet, CMSE or DMSE switches report extend and retract positions on the 250 mm travel, while the rear rod carries a flag for a second sensing point on a pick-and-place gantry.
Is the Airtac ACED Double-acting Compact Cylinder ACED50X250SB the Right Cylinder?
Step up from a 40 mm bore (571.8 N at 0.5 MPa) if your press or clamp needs more than about 570 N; drop to a 63 mm bore (1458.1 N at 0.5 MPa) when 881.2 N leaves too little margin. Both directions deliver identical force because both strokes use the rod-side area. Note that the piston will drift if air is lost, so add a rod lock or pilot check valve for a held vertical load. FA/FB flanges, LB feet, CA/CB clevises and FTC brackets bolt to the ISO 21287 face, and I/Y rod knuckles suit the male threaded rod ends.
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 ACED50X250SB FAQ
Because it is a double-rod cylinder, force is identical in both directions: 881.2 N at 0.5 MPa and 1233.7 N at 0.7 MPa, equal to a maximum of about 179.7 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, speed 30-500 mm/s, and the 250 mm stroke is the maximum standard stroke for the 50 mm bore.
The ISO 21287 short body takes about 50% less mounting length than an ISO 15552 profile cylinder, so it slots into tight gantries. The S in ACED50X250SB means the optional -S magnet is fitted on this unit, enabling CMSE / DMSE switches in the body slots; models ordered without -S carry no magnet. A fixed TPU bumper at each end absorbs end-of-stroke shock.
