About the Airtac ACE Compact Cylinder ACE32X20SB
This AirTAC ACE32X20SB is a double acting ISO 21287 compact cylinder with a 32 mm bore and a 20 mm stroke, delivering 402.1 N of push force at 0.5 MPa. Its short, hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, making it ideal for tight machine frames and guarding.
With the optional -S magnet fitted, this unit works with CMSE or DMSE reed and solid-state switches for reliable position sensing. For a real-world load, plan for roughly 24.6 kg of safe vertical lift at 0.5 MPa (about 60% of the theoretical push force), so you can match it to actual part weights without over-specifying.

Where the Airtac ACE Compact Cylinder ACE32X20SB Is Used
Fixture Clamping
Use in a CNC machine vise or work-holding fixture to clamp small parts with 402.1 N of force at 0.5 MPa, ensuring repeatable positioning in a compact envelope.
Pneumatic Stop
Mount on a conveyor line to act as a stop or diverter for lightweight cartons, cycling at speeds up to 500 mm/s with the fixed TPU bumper absorbing end-of-stroke impact.
Guard Door Interlock
Operate a sliding safety guard on a packaging machine, where the 20 mm stroke and short body fit within the guard frame, and the optional magnet signals door position to the PLC.
Is the Airtac ACE Compact Cylinder ACE32X20SB the Right Cylinder?
For lighter indexing tasks, the ACE25X20 offers 245.4 N push at 0.5 MPa, while stepping up to the ACE40X20 gives 628.3 N push for heavier fixtures. This 32 mm bore with a 20 mm stroke suits short, frequent moves in compact automation cells.
Since the magnet is fitted, order CMSE or DMSE switches to confirm position. The male rod thread (B) simplifies direct coupling to linkages or tooling. Remember, this cylinder does not hold its load when air pressure is lost, so add a rod lock or pilot check valve for vertical applications.
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 ACE32X20SB 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 figures are based on the 32 mm bore and 12 mm rod.
The ACE32X20SB has a hard-anodized aluminium body that is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight spaces like machine guards or gantries. It includes a fixed TPU bumper at both ends to reduce noise and impact, and the optional -S magnet allows mounting CMSE or DMSE sensors for position feedback.
