About the Airtac ACE Compact Cylinder ACE40X80S
This AirTAC ACE40X80S is a double acting ISO 21287 compact cylinder that extends and retracts its rod with air pressure. With a 40 mm bore it delivers 628.3 N of push force and 571.8 N of pull force at 0.5 MPa, making it a solid choice for medium-duty automation tasks.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits into tight machine guards and compact jigs. The optional -S magnet is fitted here, enabling CMSE or DMSE switches for position sensing.

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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 572 N |
| 0.7 MPa | 880 N | 800 N |
| Max (@1.0 MPa) | 128 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 ACE40X80S Is Used
Compact Jig Clamping
Use in a CNC machine fixture to clamp small parts with 628.3 N force, fitting into the tight space around the spindle where a longer cylinder would not fit.
Sorting Gate Actuator
Drive a diverter gate on a packaging conveyor, pushing 80 mm stroke to redirect boxes weighing up to 38 kg at 0.5 MPa operating pressure.
Guard Door Interlock
Actuate a safety guard door on a press brake, using the compact body to fit within the machine frame and the magnet for position feedback via a CMSE switch.
Is the Airtac ACE Compact Cylinder ACE40X80S the Right Cylinder?
For lighter work, consider the ACE32X80 with 402.1 N push, or step up to the ACE50X80 if you need 981.7 N of push force. This 40 mm bore model suits applications where space is limited but force requirements are moderate. The fixed TPU bumper absorbs end-of-stroke energy, but it does not hold a load if air pressure is lost, so use a rod lock or pilot check valve for position holding. Mounting options include FA/FB flange, LB foot, CA/CB clevis, and SDB pivot brackets, all compatible with the ISO 21287 face.
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 ACE40X80S FAQ
At 0.5 MPa, push force is 628.3 N and pull force is 571.8 N. At 0.7 MPa, push is 879.6 N and pull is 800.5 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa. The port is 1/8 inch, and the rod thread is female M8x1.25.
The ACE40X80S has a body about 50% shorter than an ISO 15552 profile cylinder, so it saves valuable mounting space in tight fixtures. The fixed TPU bumper at both ends absorbs impact, but it does not lock the rod, so use a separate brake for holding loads. The fitted -S magnet allows CMSE or DMSE switches for reliable position sensing.
