Airtac ACE Compact Cylinder ACE25X90SB
The AirTAC Airtac ACE Compact Cylinder ACE25X90SB is a genuine double acting ISO 21287 compact air cylinder with a Ø25mm 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 ACE25X90SB
This AirTAC ACE25X90SB is a double acting compact cylinder that extends and retracts its 10 mm rod with air pressure on both strokes. With a 25 mm bore it delivers 245.4 N of push force and 206.2 N of pull force at 0.5 MPa, so it suits light assembly and clamping 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 it fit inside tight machine guards and compact jigs. The optional -S magnet is fitted on this model, so you can mount CMSE or DMSE reed switches for position sensing. For a real-world load, plan on about 15 kg of safe vertical lift at 0.5 MPa, which gives you a comfortable 2:1 safety margin from the rated force.

Where the Airtac ACE Compact Cylinder ACE25X90SB Is Used
Compact Jig Clamping
Use the ACE25X90SB to clamp small parts in a CNC fixture where the short ISO 21287 body fits under a workholding arm without interfering with tool paths.
Carton Tabbing
Drive a tab-folding mechanism on a packaging line with 245.4 N push force, cycling at up to 500 mm/s to keep up with a moderate-speed conveyor.
Part Presence Check
With the -S magnet fitted, mount a CMSE reed switch to confirm the rod is extended, verifying that a small bracket or cover is present before the next station.
Is the Airtac ACE Compact Cylinder ACE25X90SB the Right Cylinder?
For lighter work, the ACE20X90 delivers 157.1 N push at 0.5 MPa, while the ACE32X90 steps up to 402.1 N push if you need more force. This 25 mm bore version with a 90 mm stroke is a middle-ground choice for compact automation. Since it is double acting, it will not hold its position if air pressure is lost; add a pilot check valve or rod lock if you must hold a load in place. The male rod thread (B code) simplifies mounting to a clevis or rod end, and the M5x0.8 port keeps plumbing simple for small-bore systems.
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 ACE25X90SB FAQ
At 0.5 MPa, push force is 245.4 N and pull force is 206.2 N. At 0.7 MPa, push is 343.6 N and pull is 288.6 N. The theoretical maximum force is 50.1 kgf at 1.0 MPa. Operating pressure range is 0.15-1.0 MPa (22-145 psi).
The body is about 50% shorter than an ISO 15552 profile cylinder, so it fits in machine guards, gantries, and fixtures where a longer cylinder would not. It uses 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.
