Airtac ACE Compact Cylinder ACE32X20BH
The AirTAC Airtac ACE Compact Cylinder ACE32X20BH is a genuine double acting ISO 21287 compact air cylinder with a Ø32mm bore and 20mm 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 ACE32X20BH
This ACE32X20BH is a double acting ISO 21287 compact cylinder that uses air to both extend and retract its 12 mm rod. The 32 mm bore delivers 402.1 N of push force at 0.5 MPa, which is enough to handle light assembly tasks; a practical rule is to plan for about 24 kg of safe vertical lift (roughly 0.6 times the push force divided by gravity) to keep a 2:1 margin. Its hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight machine guarding and compact jigs where a full-length cylinder would not fit.
The male rod thread (B code) simplifies mounting of custom tooling, and the 1/8" port matches standard fittings for quick air connection. This version has no magnet, so it cannot accept CMSE or DMSE sensors; order the optional -S code if you need position sensing. The fixed TPU bumper at both ends absorbs end-of-stroke impact, and the S45C hard-chrome plated rod resists wear in repetitive cycles.

Where the Airtac ACE Compact Cylinder ACE32X20BH Is Used
Compact Jig Clamping
Use in a small pneumatic jig on a CNC machine to clamp thin aluminum parts during drilling, where the 402.1 N push force holds the workpiece securely and the short body fits under the spindle guard.
Label Applicator Press
Mount in a labeling machine to press labels onto small boxes; the 20 mm stroke provides a quick, repeatable motion at speeds up to 500 mm/s, and the male rod thread simplifies attaching a custom applicator pad.
Test Fixture Actuator
In a quality lab, actuate a small probe to test switch contacts; the double acting design retracts the probe positively, and the fixed TPU bumper prevents damage at the end of each cycle.
Is the Airtac ACE Compact Cylinder ACE32X20BH the Right Cylinder?
For a lighter push, the ACE25X20 with a 25 mm bore produces 245.4 N at 0.5 MPa, while stepping up to the ACE40X20 gives 628.3 N push for heavier loads. Since this unit lacks a magnet, choose the -S variant if you need to mount CMSE or DMSE switches for position feedback. The 20 mm stroke suits short-travel applications, and the male rod thread allows direct attachment of fixtures without a rod-end adapter.
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 ACE32X20BH 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), with a proof pressure of 1.5 MPa (215 psi).
The ACE32X20BH follows ISO 21287, giving a body about 50% shorter than an ISO 15552 profile cylinder, which saves space in tight fixtures. It has a fixed TPU bumper at both ends to absorb impact, and mounting options like FA/FB flanges, LB foot brackets, and CA/CB clevises bolt directly to the face. Note that this version has no magnet, so order the -S option to use CMSE or DMSE sensors.
