About the Airtac ACE Compact Cylinder ACE20X45S
This AirTAC ACE20X45S is a double acting ISO 21287 compact cylinder that uses air to both extend and retract its 10 mm rod. Its 20 mm bore delivers a 157.1 N push force at 0.5 MPa, so it suits light assembly and clamping tasks where space is tight.
The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, letting it fit inside machine guards and compact jigs. With the optional -S magnet fitted, this model works with CMSE or DMSE switches for position sensing. For a real-world load, plan for about 9.6 kg of vertical lift at 0.5 MPa (157.1 N divided by 9.81, then halved for a safety margin).

Where the Airtac ACE Compact Cylinder ACE20X45S Is Used
Compact Jig Clamping
Use the ACE20X45S to clamp small parts in a CNC fixture. Its 157.1 N push at 0.5 MPa holds light workpieces securely, and the short body fits between vise jaws without protruding.
Label Applicator Press
In a packaging line, this cylinder can press labels onto small cartons. The 45 mm stroke provides enough travel for the applicator head, and the 117.8 N pull retracts it quickly for the next cycle.
Automated Inspection Stop
Mount the ACE20X45S on a conveyor to stop or divert small parts for inspection. The -S magnet lets you add CMSE switches to confirm the stop position, and the compact size fits under the conveyor frame.
Is the Airtac ACE Compact Cylinder ACE20X45S the Right Cylinder?
Choose this ACE20X45S when you need a 45 mm stroke in a small footprint. If you need more force, step up to a 25 mm bore, which pushes 245.4 N at 0.5 MPa, or step down to a 16 mm bore for 100.5 N. The M5x0.8 port is standard for this bore size, and the fixed TPU bumper at both ends handles speeds from 30 to 500 mm/s.
Since this model includes the -S magnet, you can mount CMSE or DMSE switches for end-of-stroke detection. The female M6x1.0 rod thread accepts standard attachments, and the compact body mounts with FA/FB flanges, LB foot brackets, or CA/CB clevis options. Remember, this cylinder does not hold position when air is lost, so 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 ACE20X45S FAQ
At 0.5 MPa, the push force is 157.1 N and the pull force is 117.8 N. At 0.7 MPa, push is 219.9 N and pull is 164.9 N. The theoretical maximum force is 32 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa (22-145 psi), and the speed range is 30-500 mm/s.
The ACE20X45S has a hard-anodized aluminium body that is about 50% shorter than an ISO 15552 profile cylinder, so it fits in tight spaces like machine guards and small jigs. It has a fixed TPU bumper at both ends to absorb end-of-stroke impact, and the optional -S magnet allows CMSE or DMSE switch mounting for position feedback.
