Airtac ACE Compact Cylinder ACE50X250
The AirTAC Airtac ACE Compact Cylinder ACE50X250 is a genuine double acting 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 ACE Compact Cylinder ACE50X250
This AirTAC ACE50X250 is a double acting compact cylinder built to ISO 21287, with a 50 mm bore and a 250 mm stroke. Its hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight machine frames and guarding where a full-length unit will not. The piston rod is S45C carbon steel with hard-chrome plating, and the fixed TPU bumper absorbs energy at both ends of travel.
At 0.5 MPa this unit delivers 981.7 N of push force and 881.2 N of pull force, which translates to a practical working load of about 60 kg when you apply a 0.6 safety factor. That means you can confidently move or clamp parts weighing up to roughly 60 kg at moderate speeds, while the 1/8" port allows standard fittings. The optional -S magnet is not fitted here, so no CMSE or DMSE sensor can be mounted unless you order the -S version.

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 | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 881 N |
| 0.7 MPa | 1374 N | 1234 N |
| Max (@1.0 MPa) | 200 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac ACE Compact Cylinder ACE50X250 Is Used
Jig Clamping
Use the ACE50X250 to clamp sheet metal parts in a welding jig, with 981.7 N push force holding fixtures firmly at 0.5 MPa. Its short body fits between locating pins and weld guns in tight assembly cells.
Package Stop
Mount this cylinder on a packaging conveyor to stop or divert cartons weighing up to 60 kg. The 250 mm stroke provides ample reach, and the fixed TPU bumper prevents shock to the product at end of stroke.
Pallet Transfer
In a warehouse sorting line, this double acting cylinder pushes pallets or totes off a roller conveyor. The 881.2 N pull force retracts the pusher reliably, and the compact body saves space along the transfer deck.
Is the Airtac ACE Compact Cylinder ACE50X250 the Right Cylinder?
For lighter duty, the ACE40X250 offers 628.3 N push at 0.5 MPa, while the ACE63X250 steps up to 1558.6 N push. This ACE50X250 sits in the middle, giving you a balance of force and compact size. Since this is a double acting cylinder, it uses air to both extend and retract the rod, but it does not hold position if air pressure is lost - for a held load, add a rod lock or pilot check valve. The body has magnet slots, but the magnet is optional, so order the -S code if you need sensor feedback. Mounting options include FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, and FTC brackets, all compatible with the ISO 21287 face.
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 ACE Compact Cylinder ACE50X250 FAQ
At 0.5 MPa, push force is 981.7 N and pull force is 881.2 N. At 0.7 MPa, push is 1374.4 N and pull is 1233.7 N. The theoretical maximum force is 200.2 kgf at 1.0 MPa. Operating pressure range is 0.15-1.0 MPa (22-145 psi), with proof pressure at 1.5 MPa (215 psi).
Yes, it is an ISO 21287 compact cylinder, with a body about 50% shorter than an ISO 15552 profile cylinder. It has a fixed TPU bumper at both ends, not an adjustable cushion. The magnet is optional - this model has no magnet, so to use CMSE or DMSE switches, you must order the -S version with the built-in magnet.
