About the Airtac ACE Compact Cylinder ACE32X20
This AirTAC ACE32X20 is a double acting ISO 21287 compact cylinder with a 32 mm bore and a 20 mm stroke. It produces 402.1 N of push force and 345.6 N of pull force at 0.5 MPa, with a theoretical maximum of 82 kgf at 1.0 MPa. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, making it ideal for tight machine frames and guarding. For a real workload, plan on about 241 N (24.6 kgf) of usable force at 0.5 MPa, which safely lifts roughly 12 kg vertically with a 2:1 margin.
The body is hard-anodized aluminium alloy with a roller-burnished bore, and the S45C steel rod is hard-chrome plated. A fixed TPU bumper at each end absorbs impact, and the operating pressure range is 0.15-1.0 MPa (22-145 psi) with speeds from 30-500 mm/s. This model has no magnet fitted, so it cannot accept CMSE or DMSE sensors unless you order the optional -S code. The port is 1/8" PT, and the female rod thread is M8x1.25.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 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 ACE32X20 Is Used
Jig Clamping on CNC Fixtures
Use the ACE32X20 to clamp small parts in a CNC milling fixture. The 402.1 N push force at 0.5 MPa holds components securely during light machining, and the short body fits under the spindle guard.
Carton Tabbing in Packaging Lines
In a carton erecting machine, this cylinder drives a tab-folding mechanism. The 20 mm stroke is enough to fold and hold the flap, while the 345.6 N pull force retracts the tool quickly for the next cycle.
Stop Gate on a Small Conveyor
Mount the ACE32X20 with an LB foot bracket to actuate a stop gate on a light assembly conveyor. The 402.1 N push at 0.5 MPa lifts the gate, and the fixed TPU bumper prevents impact noise at end of stroke.
Is the Airtac ACE Compact Cylinder ACE32X20 the Right Cylinder?
When sizing, compare this 32 mm bore with the 25 mm bore (245.4 N push at 0.5 MPa) for lighter loads, or step up to the 40 mm bore (628.3 N push at 0.5 MPa) for more margin. The 20 mm stroke suits short indexing moves; the maximum standard stroke for this bore is 200 mm, so longer travel is available as a made-to-order option. This cylinder does not hold its position if air pressure is lost, so for vertical loads or safety-critical applications, add a rod lock or pilot check valve. Choose the -S code if you need the magnet for CMSE or DMSE switches, and select from FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, or FTC mounting brackets to match 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 ACE32X20 FAQ
At 0.5 MPa, the push force is 402.1 N and the pull force is 345.6 N. At 0.7 MPa, push is 563 N and pull is 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa. These values are for double acting operation, where air extends and retracts the rod.
The ACE32X20 is an ISO 21287 compact cylinder, so its body is about 50% shorter than an ISO 15552 profile cylinder of the same bore. This saves space in tight machines. Sensors are not included by default; you must order the -S code to get the magnet, which then allows CMSE or DMSE switches to be mounted.
