About the Airtac ACE Compact Cylinder ACE20X45B
This AirTAC ACE20X45B is a double acting ISO 21287 compact cylinder with a 20 mm bore and a 45 mm stroke. It delivers a 157.1 N push force and a 117.8 N pull force at 0.5 MPa, with a theoretical maximum of 32 kgf at 1.0 MPa.
The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, fitting into tight machine frames. The male rod thread (B code) simplifies attachment, and the hard-anodized aluminium body with S45C hard-chrome rod resists wear. As a practical rule, plan for about 94 N of usable work at 0.5 MPa, which lifts roughly 9.6 kg vertically with a 2:1 safety margin.

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 (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 118 N |
| 0.7 MPa | 220 N | 165 N |
| Max (@1.0 MPa) | 32 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 ACE20X45B Is Used
Fixture Clamping
Clamps small parts in a CNC fixture with 157.1 N push force at 0.5 MPa, holding aluminum brackets securely during drilling.
Label Applicator
Drives a label tamp head on a carton sealing line, using the 45 mm stroke to press labels onto moving boxes at speeds up to 500 mm/s.
Guard Door Stop
Positions a safety guard stop on a light assembly bench, with the compact body fitting under a work surface where a longer cylinder would not.
Is the Airtac ACE Compact Cylinder ACE20X45B the Right Cylinder?
For a lighter duty, the ACE16X45 offers 100.5 N push at 0.5 MPa, while stepping up to the ACE25X45 provides 245.4 N push. This ACE20X45B has no magnet fitted, so CMSE or DMSE sensors cannot be used unless you order the optional -S version. The M5x0.8 port suits small-bore air circuits, and the male rod thread works with standard clevis or rod-end accessories.
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 ACE20X45B FAQ
At 0.5 MPa, push is 157.1 N and pull is 117.8 N. At 0.7 MPa, push is 219.9 N and pull is 164.9 N. The theoretical maximum force is 32 kgf at 1.0 MPa. Operating pressure range is 0.15-1.0 MPa (22-145 psi).
No, this model has no magnet because the -S code was not ordered. Without the optional -S magnet, CMSE or DMSE switches cannot be fitted. The compact ISO 21287 body has magnet slots, but the magnet itself is only added when you specify the -S option.
