Airtac ACE Compact Cylinder ACE80X25SB
The AirTAC Airtac ACE Compact Cylinder ACE80X25SB is a genuine double acting ISO 21287 compact air cylinder with a Ø80mm bore and 25mm stroke, 1/4" 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 ACE80X25SB
This AirTAC ACE80X25SB is a compact double-acting cylinder that extends and retracts its rod with air pressure, delivering a 2513.3 N push force at 0.5 MPa. Its ISO 21287 short body is about 50% shorter than an ISO 15552 profile cylinder, so it fits neatly into tight machine frames where a full-length unit will not.
With the optional -S magnet already fitted, this model works with CMSE or DMSE reed and solid-state switches for reliable position sensing. For a real-world load, plan on about 154 kg of safe vertical lifting at 0.5 MPa (0.6 times the push force), giving you a practical margin for jigs and fixtures. The hard-anodized aluminium body and S45C hard-chrome rod resist wear in continuous cycling.

Where the Airtac ACE Compact Cylinder ACE80X25SB Is Used
Fixture Clamping
Use in a CNC machine fixture to clamp a 150 kg workpiece during drilling. The 2513.3 N push at 0.5 MPa holds parts firmly, and the short body fits under the machine guard.
Carton Pressing
In a packaging line, this cylinder presses folded cartons flat before sealing. The 25 mm stroke cycles quickly at up to 500 mm/s, and the fixed TPU bumper prevents end-of-stroke shock.
Product Stop Gate
Mount on a conveyor to stop and release boxes for labeling. The 80 mm bore provides enough force to hold back a line of products, and the optional magnet lets a CMSE switch confirm the gate position.
Is the Airtac ACE Compact Cylinder ACE80X25SB the Right Cylinder?
For lighter duty, consider the ACE63X25 with a 1558.6 N push at 0.5 MPa, or step up to the ACE100X25 for a 3927.0 N push if you need more force. This 80 mm bore version suits medium-to-heavy automation tasks where the 25 mm stroke is enough for clamping, pressing, or positioning. The male rod thread (B code) simplifies mounting with rod-end accessories, and the 1/4" port matches standard air lines. Remember, this cylinder does not hold its position when air is lost, so add 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 ACE80X25SB FAQ
At 0.5 MPa, the push force is 2513.3 N and the pull force is 2356.2 N. At 0.7 MPa, push is 3518.6 N and pull is 3298.7 N. The theoretical maximum force is 512.6 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa (22-145 psi), and the proof pressure is 1.5 MPa (215 psi).
The ACE80X25SB has a hard-anodized aluminium body that is about 50% shorter than an ISO 15552 profile cylinder, saving valuable mounting space. It uses a fixed TPU bumper at both ends to absorb impact, not an adjustable cushion. The optional -S magnet is fitted here, so you can add CMSE or DMSE switches for position sensing. The rod is S45C carbon steel with hard-chrome plating for durability.
