Airtac ACE Compact Cylinder ACE20X5S
The AirTAC Airtac ACE Compact Cylinder ACE20X5S is a genuine double acting ISO 21287 compact air cylinder with a Ø20mm bore and 5mm 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 ACE20X5S
This AirTAC ACE20X5S is a double acting compact cylinder that extends and retracts its 10 mm rod with air pressure on both strokes. With a 20 mm bore it delivers 157.1 N of push force at 0.5 MPa, which is enough to handle light clamping and positioning tasks in automated assembly lines.
The ISO 21287 short body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight guarding and compact jigs where a full-length cylinder would not. The optional -S magnet is fitted on this model, so you can mount CMSE or DMSE reed and solid-state switches to confirm rod position. For a real-world load, plan on about 9.6 kg of safe vertical lift at 0.5 MPa, which is 60% of the rated push force divided by gravity.

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 ACE20X5S Is Used
Small Parts Ejection
Use the 5 mm stroke to push small stamped components off a die or into a chute in a stamping press, where the short body fits under the tooling.
Fixture Clamping
Clamp thin workpieces in a CNC fixture with 157.1 N push force, and the compact body leaves room for other clamps and sensors on a crowded tombstone.
Position Verification
With the fitted -S magnet, mount a CMSE switch to confirm the rod is fully extended or retracted in a high-speed sorting station, enabling reliable part tracking.
Is the Airtac ACE Compact Cylinder ACE20X5S the Right Cylinder?
For a lighter duty, the ACE16X5S offers 100.5 N push at 0.5 MPa, while stepping up to the ACE25X5S gives you 245.4 N push for heavier parts. This 5 mm stroke suits short pick-and-place moves, and the M5x0.8 port keeps plumbing compact. The fixed TPU bumper at both ends absorbs impact at high cycle rates, but it does not hold a load if air pressure is lost, so add a rod lock or pilot check valve for vertical applications.
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 ACE20X5S 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 at 1.0 MPa is 32 kgf. The rod is 10 mm, the port is M5x0.8, and the maximum standard stroke for this bore is 100 mm.
The magnet is an optional -S feature, and this model includes it, so you can mount CMSE or DMSE reed or solid-state switches to detect rod position. Without the -S code, no magnet is present and sensors cannot work. The cylinder has a fixed TPU bumper at both ends, not an adjustable cushion, and it operates at speeds from 30 to 500 mm/s.
