Airtac ACE Compact Cylinder ACE50X90S
The AirTAC Airtac ACE Compact Cylinder ACE50X90S is a genuine double acting ISO 21287 compact air cylinder with a Ø50mm bore and 90mm 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 ACE50X90S
This AirTAC ACE50X90S is a double acting ISO 21287 compact cylinder with a 50 mm bore and a 90 mm stroke. Its hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder, so it slides into tight jigs and guards where a full-length unit will not fit.
At 0.5 MPa it pushes with 981.7 N and pulls with 881.2 N, which lifts about 60 kg vertically with a 2:1 safety margin. The optional -S magnet is fitted here, so CMSE or DMSE switches can mount directly to sense the piston position. A fixed TPU bumper at each end absorbs impact, and the S45C hard-chrome rod resists wear in dirty shop air.

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 ACE50X90S Is Used
Fixture Clamping
Clamp a 50 mm wide workpiece in a CNC fixture with 981.7 N push force at 0.5 MPa, fitting the compact body between vise jaws.
Carton Tamping
Tamp folded cartons in a packaging line with a 90 mm stroke, using the pull force of 881.2 N to retract quickly after each cycle.
Guard Door Actuation
Slide a machine guard door open and closed with the 50 mm bore, taking advantage of the short body to mount inside a safety enclosure.
Is the Airtac ACE Compact Cylinder ACE50X90S the Right Cylinder?
For lighter work, the ACE40X90 delivers 628.3 N push at 0.5 MPa, while the ACE63X90 steps up to 1558.6 N push. This 50 mm bore suits medium automation tasks where a 90 mm stroke fits a compact envelope. Since the magnet is fitted, pair it with a CMSE reed switch for end-of-stroke sensing. Mount with FA flange, LB foot, or CA clevis brackets; the rod end is female M10x1.5 thread. Remember, this cylinder does not hold position when air is removed - add a rod lock or pilot check valve for vertical loads.
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 ACE50X90S FAQ
At 0.5 MPa, push is 981.7 N and pull 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 is 0.15-1.0 MPa (22-145 psi).
The ACE50X90S body is about 50% shorter than an ISO 15552 profile cylinder, so it fits in confined areas like inside a gantry or behind a panel. It uses a fixed TPU bumper at both ends to absorb impact, not an adjustable air cushion. The optional -S magnet is fitted here, enabling CMSE or DMSE switches for position sensing.
