Airtac ACE Compact Cylinder ACE50X50
The AirTAC Airtac ACE Compact Cylinder ACE50X50 is a genuine double acting ISO 21287 compact air cylinder with a Ø50mm bore and 50mm 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 ACE50X50
This AirTAC ACE50X50 is a double acting ISO 21287 compact cylinder with a 50 mm bore and 50 mm stroke, delivering 981.7 N of push force at 0.5 MPa. Its hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight machine guards and compact jigs where a full-length cylinder cannot. The S45C steel rod is hard-chrome plated, and a fixed TPU bumper at each end absorbs end-of-stroke impact.
For real-world sizing, plan for roughly 60 kg of safe working load at 0.5 MPa, which is about 0.6 times the 981.7 N push rating. This cylinder can lift about 60 kg vertically with a 2:1 safety margin, making it a practical choice for light press operations or clamping fixtures. The optional -S magnet is not fitted here, so CMSE or DMSE sensors cannot be mounted unless you order the -S version.

Where the Airtac ACE Compact Cylinder ACE50X50 Is Used
Compact Jig Clamping
Use this ACE50X50 to clamp small parts in a CNC fixture where the short body saves space and the 981.7 N push force holds components securely during drilling or tapping operations.
Carton Ejection
In a packaging line, this cylinder can push finished cartons off a conveyor onto a chute, with the 50 mm stroke providing just enough travel to clear the edge without taking up extra floor space.
Light Press Operation
For a small bench press or staking operation, the ACE50X50 delivers about 60 kg of safe working force at 0.5 MPa, suitable for pressing bushings or rivets into plastic or soft metal parts.
Is the Airtac ACE Compact Cylinder ACE50X50 the Right Cylinder?
When selecting this ACE50X50, compare it with the ACE40X50 which pushes 628.3 N at 0.5 MPa, or step up to the ACE63X50 which pushes 1558.6 N at the same pressure. For a 50 mm bore, the 50 mm stroke is within the 250 mm maximum standard stroke, so no non-standard order is needed. Remember, this cylinder does not hold its position if air pressure is lost; for a held load, add a rod lock or pilot check valve. The 1/8" port matches the bore size, and you can choose FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, or FTC mounting brackets to fit your fixture.
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 ACE50X50 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 at 1.0 MPa is 200.2 kgf. The operating pressure range is 0.15-1.0 MPa (22-145 psi), with a proof pressure of 1.5 MPa (215 psi).
Yes, it is an ISO 21287 compact cylinder with a hard-anodized aluminium body that is 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 without the -S code has no magnet, so CMSE or DMSE sensors cannot be used unless you order the -S version.
