Airtac ACE Compact Cylinder ACE20X90SB
The AirTAC Airtac ACE Compact Cylinder ACE20X90SB is a genuine double acting ISO 21287 compact air cylinder with a Ø20mm bore and 90mm 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 ACE20X90SB
This AirTAC ACE20X90SB is a double acting compact cylinder that extends and retracts its rod with air pressure on both strokes. With a 20 mm bore it delivers 157.1 N of push force and 117.8 N of pull force at 0.5 MPa, so it suits light assembly and clamping tasks where space is tight.
The ISO 21287 body is about 50% shorter than an ISO 15552 profile cylinder, which helps it fit inside machine guards and compact jigs. The optional -S magnet is fitted on this model, so you can mount CMSE or DMSE reed or solid-state switches for position sensing. For a real workload, plan around 94 N (about 9.6 kg) as a safe vertical lift at 0.5 MPa, keeping a 2:1 margin over the rated force.

Where the Airtac ACE Compact Cylinder ACE20X90SB Is Used
Compact Clamping Fixture
Use in a small pneumatic vise on a benchtop drill press to hold 20 mm thick aluminum parts during hole drilling, with the 90 mm stroke providing enough travel to clear the workpiece.
Carton Tabbing
Drive a tab-folding mechanism on a packaging line that folds and presses cardboard flaps on small boxes, using the 157.1 N push force to crease and hold the flap in place.
Guard Door Interlock
Actuate a small guard door latch on a lab instrument, where the short body fits behind a panel and the male rod thread connects directly to a latch linkage for a positive open or closed position.
Is the Airtac ACE Compact Cylinder ACE20X90SB the Right Cylinder?
For lighter duty, the ACE16 bore offers 100.5 N push at 0.5 MPa, while stepping up to the ACE25 bore gives 245.4 N push for heavier parts. The 90 mm stroke fits within the 100 mm maximum standard stroke for this bore, so no custom order is needed. This model has a male rod thread (B code) and a PT port thread, and the fitted magnet allows sensor feedback for automated 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 ACE20X90SB FAQ
At 0.5 MPa, push force is 157.1 N and 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 port is M5x0.8 and the rod is 10 mm with a male thread.
The ACE20X90SB has a short body that saves about 50% of the mounting length compared to an ISO 15552 profile cylinder, so it fits in confined areas like inside machine frames or behind panels. It has a fixed TPU bumper at both ends to absorb impact, and the optional -S magnet on this model enables CMSE or DMSE switch mounting for position feedback.
