Airtac ACE Compact Cylinder ACE25X80SB
The AirTAC Airtac ACE Compact Cylinder ACE25X80SB is a genuine double acting ISO 21287 compact air cylinder with a Ø25mm bore and 80mm 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 ACE25X80SB
This AirTAC ACE25X80SB is a double acting ISO 21287 compact cylinder that extends and retracts its 10 mm rod with air pressure on both strokes. Its 25 mm bore delivers 245.4 N of push force at 0.5 MPa, so it suits light assembly and clamping tasks where space is tight.
The hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder, freeing room in cramped jigs and guards. Since this model carries the optional -S magnet, you can mount CMSE or DMSE reed switches for position sensing. For a real workload, plan for roughly 15 kg of safe vertical lift at 0.5 MPa, keeping a 2:1 safety margin from the theoretical 25.0 kgf maximum.

Where the Airtac ACE Compact Cylinder ACE25X80SB Is Used
Precision Jig Clamping
Use the 245.4 N push to clamp small parts in a CNC fixture, where the short body fits between guide rails and leaves room for tooling.
Carton Tabbing
Drive a tab-folding mechanism on a packaging line at speeds up to 500 mm/s, with the 80 mm stroke matching typical carton flap depths.
Part Presence Check
With the fitted magnet, mount a CMSE switch to detect the rod position and confirm a part is seated before the next cycle starts.
Is the Airtac ACE Compact Cylinder ACE25X80SB the Right Cylinder?
For a lighter push, the ACE20X80 delivers 157.1 N at 0.5 MPa, while stepping up to the ACE32X80 gives 402.1 N for heavier parts. This 25 mm bore version balances compact size with enough force for small actuators and fixtures. The male rod thread (B) simplifies mounting with rod-end accessories, and the M5x0.8 port matches common miniature fittings. Since the magnet is fitted, order CMSE or DMSE switches to confirm position. Remember, this cylinder does not hold its load if air pressure is lost, so add a rod lock or pilot check valve for vertical applications.
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 ACE25X80SB FAQ
At 0.5 MPa, the push force is 245.4 N and the 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.
It follows ISO 21287, so its body is about 50% shorter than an ISO 15552 profile cylinder of the same bore. This lets it fit into tight machine guards and fixtures. The fixed TPU bumper at each end absorbs impact, and the optional -S magnet allows CMSE or DMSE sensor mounting.
