Airtac ACE Compact Cylinder ACE32X120SB
The AirTAC Airtac ACE Compact Cylinder ACE32X120SB is a genuine double acting ISO 21287 compact air cylinder with a Ø32mm bore and 120mm stroke, 1/8" 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 ACE32X120SB
This AirTAC ACE32X120SB is a double acting ISO 21287 compact cylinder with a 32 mm bore and 120 mm stroke. The hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight machine frames and guarding where a full-length cylinder will not. The S45C carbon-steel rod is hard-chrome plated and has a male thread (B code) for direct coupling.
At 0.5 MPa this unit pushes with 402.1 N and pulls with 345.6 N, which translates to a usable vertical lift of about 24.6 kg when you apply a 2:1 safety margin. The optional -S magnet is fitted here, so CMSE or DMSE reed and solid-state switches can be mounted for position sensing. A fixed TPU bumper at each end absorbs impact, and the operating speed range is 30-500 mm/s.

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 ACE32X120SB Is Used
Fixture Clamping
Clamp small parts in a CNC vise or workholding fixture where the short body clears the spindle and tool path. The 402.1 N push at 0.5 MPa holds typical aluminum blanks securely.
Conveyor Stop Gate
Actuate a stop gate on a light assembly conveyor to separate parts for inspection. The 120 mm stroke moves the gate fully clear, and the magnet lets a sensor confirm the gate position.
Carton Ejector
Push finished cartons off a short packing station onto a takeaway belt. The compact body mounts behind the guide rail, and the 345.6 N pull retracts the pusher quickly for the next cycle.
Is the Airtac ACE Compact Cylinder ACE32X120SB the Right Cylinder?
For lighter duty in a 25 mm bore, the ACE25X120 pushes 245.4 N at 0.5 MPa, while stepping up to a 40 mm bore gives 628.3 N push. This 32 mm bore is a balanced middle choice for moderate loads in compact spaces. The male rod thread simplifies mounting without a rod-end adapter, and the fitted magnet lets you add sensors for automated control. Remember that a plain ACE does not hold its position when air is removed, so use a rod lock or pilot check valve if the load must stay put.
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 ACE32X120SB FAQ
At 0.5 MPa the push force is 402.1 N and the pull force is 345.6 N. At 0.7 MPa the push is 563 N and the pull is 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa. The port is 1/8 inch, and the rod is 12 mm with a male M8x1.25 thread.
The magnet is an optional -S feature, and this model includes it. With the magnet fitted, you can mount CMSE reed switches or DMSE solid-state switches to detect the piston position. Without the -S code, no magnet is present and sensors cannot be used. The body has slots for the switches.
