Airtac ACE Compact Cylinder ACE20X30BH
The AirTAC Airtac ACE Compact Cylinder ACE20X30BH is a genuine double acting ISO 21287 compact air cylinder with a Ø20mm bore and 30mm stroke, M5×0.8 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 ACE20X30BH
This AirTAC ACE20X30BH is a double acting ISO 21287 compact cylinder with a 20 mm bore and a 30 mm stroke, delivering 157.1 N of push force at 0.5 MPa. Its short body, about 50% shorter than an ISO 15552 profile cylinder, fits into tight machine frames and guarding where a full-length actuator won't go.
For real work at 0.5 MPa, plan for roughly 94 N of usable force, which lifts about 9.6 kg vertically with a 2:1 safety margin. The male rod thread (B code) simplifies mounting, and the hard-anodized aluminium body with a hard-chrome S45C rod resists wear in continuous cycling.

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 ACE20X30BH Is Used
Fixture Clamping
Use in a pneumatic vise or workholding fixture to clamp small parts during drilling or tapping, where the 157.1 N push holds components firmly in place.
Label Applicator
Drive a label applicator head in a packaging line, extending and retracting to press labels onto cartons at speeds up to 500 mm/s.
Guard Door Actuator
Open and close a lightweight safety guard door on a small machine, using the compact body to fit within the guard frame and the 30 mm stroke for the door travel.
Is the Airtac ACE Compact Cylinder ACE20X30BH the Right Cylinder?
When sizing, compare with the 16 mm bore (100.5 N push at 0.5 MPa) for lighter loads or the 25 mm bore (245.4 N push at 0.5 MPa) for heavier pushes. This 20 mm bore suits medium-duty applications where space is limited. Note that without the optional -S magnet, no CMSE or DMSE sensors can be fitted, so order the -S code if you need position sensing. The M5x0.8 port matches small-bore fittings, and the fixed TPU bumper handles end-of-stroke impact without adjustment.
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 ACE20X30BH FAQ
At 0.5 MPa, push force is 157.1 N and pull force 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 is 0.15-1.0 MPa (22-145 psi), and proof pressure is 1.5 MPa (215 psi).
The ISO 21287 compact design saves about 50% of the mounting length of an ISO 15552 profile cylinder, making it ideal for tight spaces. However, this model has no magnet, so CMSE or DMSE sensors cannot be used unless you order the optional -S magnet code. The fixed TPU bumper at both ends absorbs end-of-stroke energy without adjustment.
