About the Airtac ACE Compact Cylinder ACE32X20S
This AirTAC ACE32X20S is a double acting ISO 21287 compact cylinder, with air extending and retracting the 12 mm rod. Its 32 mm bore delivers 402.1 N push and 345.6 N pull at 0.5 MPa, so it suits light assembly tasks. The short body cuts about 50% of the mounting length of an ISO 15552 profile cylinder, freeing space in tight fixtures. A fixed TPU bumper at each end absorbs impact, and the hard-anodized aluminium body resists wear.
With the optional -S magnet fitted, this unit works with CMSE or DMSE reed and solid-state switches for position sensing. For a safe working load, plan on about 241 N at 0.5 MPa, which lifts roughly 25 kg vertically with a 2:1 margin. The 1/8" port keeps plumbing simple, and the female M8x1.25 rod thread accepts standard attachments. Operating pressure is 0.15-1.0 MPa (22-145 psi), with speeds from 30-500 mm/s.

Where the Airtac ACE Compact Cylinder ACE32X20S Is Used
Fixture Clamping
Use the ACE32X20S to clamp small parts in a CNC vise or workholding fixture. The 402.1 N push at 0.5 MPa holds components securely during drilling or milling, and the compact body fits under machine guards.
Pusher on Conveyor
Mount this cylinder beside a conveyor to divert or reject lightweight boxes. With a 20 mm stroke, it nudges items off the line at speeds up to 500 mm/s, and the optional magnet lets you confirm the pusher position.
Carton Tabbing
In a packaging line, the ACE32X20S can press tape or fold flaps on small cartons. Its short stroke and 345.6 N pull at 0.5 MPa handle repetitive motions without taking up much space in the sealing station.
Is the Airtac ACE Compact Cylinder ACE32X20S the Right Cylinder?
For a lighter push, consider the ACE25X20S with 245.4 N at 0.5 MPa, or step up to the ACE40X20S for 628.3 N. This 32 mm bore balances force and footprint for medium-duty automation. Since the magnet is fitted, you can add CMSE switches for end-of-stroke detection. Mount with FA/FB flanges, LB foot, or CA/CB clevis brackets to match your jig. Note that this cylinder does not hold position when air is lost; 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 ACE32X20S 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 is 82 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa (22-145 psi).
The ACE32X20S has a short body that saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits in tight spaces. It uses a fixed TPU bumper at both ends for impact absorption, not an adjustable cushion. The optional -S magnet allows CMSE or DMSE switches for position sensing.
