Airtac ACE Compact Cylinder ACE20X25B
The AirTAC Airtac ACE Compact Cylinder ACE20X25B is a genuine double acting ISO 21287 compact air cylinder with a Ø20mm bore and 25mm 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 ACE20X25B
This AirTAC ACE20X25B is a double acting ISO 21287 compact cylinder that extends and retracts its 10 mm rod with air pressure on both strokes. Its hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight machine guards and indexing fixtures where a full-length unit will not. The male rod thread (B code) lets you bolt on a custom tool or coupling directly, and the M5x0.8 port keeps plumbing simple for small-bore automation.
At 0.5 MPa this bore delivers 157.1 N push and 117.8 N pull, so a practical rule is to plan for about 94 N of real work after a safety margin. That translates to lifting roughly 9.6 kg vertically with a 2:1 factor, which helps you match it to a light pick-and-place arm or a small clamp. The fixed TPU bumper absorbs end-of-stroke impact, and the operating range spans 0.15-1.0 MPa (22-145 psi) with speeds from 30 to 500 mm/s.

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 ACE20X25B Is Used
Light Clamping Fixture
Use the 157.1 N push at 0.5 MPa to hold small plastic parts in a drilling or gluing jig, with the compact body fitting under a worktable.
Small Part Ejection
Mount it on a conveyor side rail to push 25 mm travel and reject lightweight components into a chute, relying on the fixed TPU bumper for quiet cycling.
Pneumatic Test Probe
Drive a contact probe or sensor tip into a test point with the male rod thread, using the 117.8 N pull to retract it cleanly after measurement.
Is the Airtac ACE Compact Cylinder ACE20X25B the Right Cylinder?
For a lighter duty, the 16 mm bore ACE16X25 gives 100.5 N push at 0.5 MPa, while stepping up to the 25 mm bore ACE25X25 provides 245.4 N push for firmer clamping. Since this unit has no magnet (no -S code), it cannot trigger CMSE or DMSE sensors; order the -S variant if you need position sensing. The male rod thread and PT port suit direct coupling, and FA/FB flange or LB foot mounts bolt onto standard ISO 21287 faces.
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 ACE20X25B FAQ
At 0.5 MPa, push is 157.1 N and pull is 117.8 N. At 0.7 MPa, push rises to 219.9 N and pull to 164.9 N. The theoretical maximum force is 32 kgf at 1.0 MPa. This double acting cylinder uses air for both extension and retraction.
No, because this model has no magnet (no -S code). The magnet is optional and only available when you order the -S variant, which then allows CMSE or DMSE switches to detect the piston position. Without the -S code, there is no magnet and no sensor mounting is possible.
