Airtac ACE Compact Cylinder ACE32X120B
The AirTAC Airtac ACE Compact Cylinder ACE32X120B 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 ACE32X120B
The AirTAC ACE32X120B is a double acting compact cylinder that extends and retracts its 12 mm rod with air pressure, delivering a 402.1 N push force at 0.5 MPa. Its ISO 21287 short body takes up about half the mounting length of an ISO 15552 profile cylinder, so it slides into tight machine frames where a full-length unit will not fit.
This version has a male rod thread (the B code) and no magnet, so it cannot accept CMSE or DMSE sensors unless you order the optional -S variant. For a 2:1 safety margin on vertical moves, plan to lift about 20 kg (402.1 N divided by 9.81 and halved) rather than the full theoretical rating, and remember the fixed TPU bumper only softens end stops, it does not hold a load in position.

Where the Airtac ACE Compact Cylinder ACE32X120B Is Used
Fixture Clamping
Mount this 32 mm bore unit on a CNC fixture to clamp small aluminium parts with 402.1 N push force, using the compact body to fit between vise jaws.
Carton Tamping
Use the 120 mm stroke to tamp folded cardboard boxes into a packing chute, relying on the 345.6 N pull stroke to retract quickly between cycles.
Guard Door Stop
Install on a machine safety guard to push a stop pin into a slot, with the male rod thread simplifying attachment to a custom bracket.
Is the Airtac ACE Compact Cylinder ACE32X120B the Right Cylinder?
For lighter indexing tasks, step down to a 25 mm bore ACE25X120 which pushes 245.4 N at 0.5 MPa, while a 40 mm bore ACE40X120 gives 628.3 N for heavier clamping. Since this cylinder has no magnet, choose the -S code if you need CMSE or DMSE switch feedback, and pair it with a pilot check valve if the load must stay put when air pressure drops.
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 ACE32X120B FAQ
At 0.5 MPa, push is 402.1 N and pull is 345.6 N. At 0.7 MPa, push is 563.0 N and pull is 483.8 N. The theoretical maximum force at 1.0 MPa is 82 kgf.
No, this ACE32X120B has no magnet because the S code was not ordered. To use CMSE or DMSE reed or solid-state switches, you must order the -S variant which includes the optional magnet. The fixed TPU bumper at both ends only absorbs end-of-stroke impact, it does not provide position sensing.
