Airtac ACE Compact Cylinder ACE20X5SB
The AirTAC Airtac ACE Compact Cylinder ACE20X5SB is a genuine double acting ISO 21287 compact air cylinder with a Ø20mm bore and 5mm stroke, M5×0.8 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 ACE20X5SB
This AirTAC ACE20X5SB is a double acting compact cylinder that uses air to both extend and retract its 10 mm rod, with a fixed TPU bumper at each end to soften the stop. Its 20 mm bore delivers 157.1 N of push force at 0.5 MPa, so it suits light clamping and indexing tasks where a full-size cylinder would be overkill.
The ISO 21287 body is about 50% shorter than an ISO 15552 profile cylinder, which lets you tuck it into tight jigs or behind guards. The optional -S magnet is fitted here, so you can add CMSE or DMSE reed switches for position sensing. For a real-world load, plan on about 9.6 kg of usable force at 0.5 MPa (157.1 N x 0.6 / 9.81), leaving a safety margin for friction and acceleration.

Where the Airtac ACE Compact Cylinder ACE20X5SB Is Used
Tight Jig Clamping
Use the ACE20X5SB to clamp small parts in a CNC fixture where the 5 mm stroke and short body fit under a work stop, delivering 157.1 N to hold a bracket during drilling.
Label Applicator
In a packaging line, this cylinder can push a label applicator head forward 5 mm to press a label onto a box, with the magnet letting a sensor confirm each cycle.
Valve Actuator
For a small pneumatic valve or a limit switch, the ACE20X5SB provides a compact push to toggle a lever, and the male rod thread accepts a custom fork for direct linkage.
Is the Airtac ACE Compact Cylinder ACE20X5SB the Right Cylinder?
For a lighter touch, the 16 mm bore gives 100.5 N push at 0.5 MPa, while stepping up to the 25 mm bore provides 245.4 N if you need more force in the same compact footprint. The 5 mm stroke is ideal for short, precise movements, and the male rod thread (B code) simplifies mounting with a clevis or rod end.
This model carries the -S magnet, so you can wire CMSE or DMSE sensors to confirm position. The M5x0.8 port is standard for this bore, and the hard-anodized aluminum body with a hard-chrome S45C rod resists wear in repetitive cycles.
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 ACE20X5SB 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) with a proof pressure of 1.5 MPa (215 psi).
The ACE20X5SB has a short body that saves about 50% of the mounting length compared to an ISO 15552 profile cylinder, so it fits into confined areas like machine guards or small fixtures. The fixed TPU bumper absorbs end-of-stroke impact, and the optional -S magnet allows CMSE or DMSE switches for position sensing.
