About the Airtac ACE Compact Cylinder ACE50X225B
This AirTAC ACE50X225B is a double acting compact cylinder built to ISO 21287, with a 50 mm bore and a 225 mm stroke. It delivers 981.7 N of push force at 0.5 MPa, so it suits mid-force automation tasks like clamping and light pressing. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which lets it fit into tight machine frames and guard enclosures where a longer cylinder will not go.
The male rod thread (B code) simplifies direct coupling to linkages, and the 1/8" port matches standard fittings. For a safe working load, plan for about 589 N at 0.5 MPa, which equals lifting roughly 60 kg vertically with a 2:1 safety margin. The fixed TPU bumper at both ends absorbs end-of-stroke impact, and the hard-anodized aluminium body with an S45C hard-chrome rod resists wear in continuous cycling.

Where the Airtac ACE Compact Cylinder ACE50X225B Is Used
Jig Clamping
Use this ACE50X225B to clamp sheet metal parts in a drilling jig, where the 981.7 N push at 0.5 MPa holds the workpiece firmly and the compact body fits under the fixture table.
Conveyor Stop Gate
Mount this cylinder at a conveyor transfer point to raise a stop gate. The 225 mm stroke lifts the gate clear of the product path, and the fixed TPU bumper handles repeated stops without shock.
Carton Pusher
In a packaging line, this cylinder pushes cartons off a roller conveyor. The 881.2 N pull at 0.5 MPa retracts the pusher arm quickly, and the male rod thread connects to a custom paddle.
Is the Airtac ACE Compact Cylinder ACE50X225B the Right Cylinder?
When sizing, compare this 50 mm bore unit with the 40 mm bore ACE40, which pushes 628.3 N at 0.5 MPa, or the 63 mm bore ACE63, which pushes 1558.6 N at 0.5 MPa. The 225 mm stroke is within the 250 mm maximum standard stroke for this bore, so it is a stock item. Since this model has no -S code, there is no magnet fitted, so CMSE or DMSE sensors cannot be used without ordering the optional -S version. For mounting, choose FA or FB flanges, LB foot brackets, CA or CB clevises, CR, SDB pivot, or FTC brackets that bolt directly to 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 ACE50X225B FAQ
At 0.5 MPa, the push force is 981.7 N and the 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. The operating pressure range is 0.15-1.0 MPa (22-145 psi), and the proof pressure is 1.5 MPa (215 psi).
This is an ISO 21287 compact cylinder, so its body is about 50% shorter than an ISO 15552 profile cylinder. That saves space in tight fixtures. The fixed TPU bumper at both ends absorbs end-of-stroke energy, but it does not lock or hold a load. For position holding, use a rod lock or pilot check valve.
