Airtac ACE Compact Cylinder ACE20X15B
The AirTAC Airtac ACE Compact Cylinder ACE20X15B is a genuine double acting ISO 21287 compact air cylinder with a Ø20mm bore and 15mm 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 ACE20X15B
This AirTAC ACE20X15B is double acting, using air to both extend and retract the 10 mm rod. With a 20 mm bore it delivers 157.1 N push and 117.8 N pull at 0.5 MPa, and 219.9 N push at 0.7 MPa, making it a solid choice for light assembly tasks.
The ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, so it fits inside tight machine guards and small jigs. The male rod thread (B code) simplifies mounting of custom tooling, and the fixed TPU bumper at both ends absorbs end-of-stroke impact. For a 2:1 safety margin on vertical lifts, plan to move about 8 kg with this unit at 0.5 MPa.

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 ACE20X15B Is Used
Small Part Ejection
Use the 157.1 N push to eject small plastic components from an injection mold or die-cast tool in a compact workcell.
Jig Clamping
Mount this cylinder in a manual assembly fixture to clamp thin sheet metal parts during drilling or riveting, where its short body saves space.
Light Packaging Index
Drive a small pusher on a packaging line to move blister packs or cartons into a chute, using the 117.8 N pull for the return stroke.
Is the Airtac ACE Compact Cylinder ACE20X15B the Right Cylinder?
For lighter work, the 16 mm bore ACE16X15B gives 100.5 N push, while stepping up to the 25 mm bore ACE25X15B provides 245.4 N push at the same pressure. This 20 mm bore is a balanced middle ground for small grippers and light indexing. Since this model has no magnet (no S code), CMSE or DMSE sensors cannot be fitted; order the -S version if you need position sensing.
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 ACE20X15B 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), with proof pressure of 1.5 MPa (215 psi).
The ACE is an ISO 21287 compact cylinder, so its body is about 50% shorter than an ISO 15552 profile cylinder, which helps in tight spaces. This model has no magnet, so you cannot mount CMSE or DMSE switches on it. To use sensors, you must order the -S version, which includes the optional magnet.
