About the Airtac ACE Compact Cylinder ACE32X40B
This AirTAC ACE32X40B is a double acting compact cylinder built to ISO 21287, with a 32 mm bore and a 40 mm stroke. It delivers 402.1 N of push force and 345.6 N of pull force at 0.5 MPa, making it a solid choice for light assembly tasks. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits into tight machine frames where space is limited.
Because this version has no -S code, it has no magnet, so CMSE or DMSE sensors cannot be mounted on it. The rod is male-threaded (B code) and the port is 1/8". For a real-world load, plan for about 24.6 kg of safe vertical lift at 0.5 MPa, which is 60% of the rated push force divided by gravity. The fixed TPU bumper at both ends absorbs end-of-stroke impact, but it does not hold or brake a load if air pressure is lost.

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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 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 ACE32X40B Is Used
Jig Clamping on CNC Fixtures
Use the ACE32X40B to clamp small parts in a CNC milling fixture, where its 402.1 N push force at 0.5 MPa secures aluminum blanks without taking up extra space on the machine table.
Sorting Gate on a Conveyor
In a packaging line, this cylinder can actuate a diverting gate to push boxes onto a side track. The 40 mm stroke provides enough travel for small cartons, and the compact body fits under the conveyor frame.
Press Plunger for Gasket Insertion
For a semi-automatic assembly station, the ACE32X40B drives a plunger to insert rubber gaskets into valve housings. Its 345.6 N pull force retracts the plunger cleanly, and the fixed TPU bumper prevents shock to the parts.
Is the Airtac ACE Compact Cylinder ACE32X40B the Right Cylinder?
When sizing this ACE32X40B, compare it with the ACE25X40 (25 mm bore, 245.4 N push at 0.5 MPa) for lighter jobs, or the ACE40X40 (40 mm bore, 628.3 N push at 0.5 MPa) for heavier work. The 32 mm bore is a middle ground for applications needing moderate force in a compact envelope. Since this unit has no magnet, order the -S version if you need position sensing with CMSE or DMSE switches. Mounting options include FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, and FTC brackets, all compatible with the ISO 21287 face. Remember, this cylinder does not hold its position when air is removed; use a rod lock or pilot check valve for load holding.
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 ACE32X40B FAQ
At 0.5 MPa, the push force is 402.1 N and the pull force is 345.6 N. At 0.7 MPa, push is 563 N and pull is 483.8 N. The theoretical maximum force at 1.0 MPa is 82 kgf. These numbers are based on the 32 mm bore and 12 mm rod.
No, this specific model has no magnet because it lacks the -S code. Without the optional -S magnet, CMSE or DMSE switches cannot be mounted. If you need position sensing, order the ACE32X40BS version instead. The cylinder uses a fixed TPU bumper at both ends, which is not adjustable, and operates at speeds from 30 to 500 mm/s.
