About the Airtac ACE Compact Cylinder ACE25X100SB
This AirTAC ACE25X100SB is a double acting ISO 21287 compact cylinder with a 25 mm bore and a 100 mm stroke, delivering 245.4 N of push force at 0.5 MPa. Its short body takes up about 50% less mounting length than an ISO 15552 profile cylinder, so it fits into tight machine frames and guarding where a full-length cylinder would 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 real-world sizing, plan on about 15 kg of usable vertical lift at 0.5 MPa (245.4 N divided by 9.81, then halved for a 2:1 safety margin), which helps you match it to an actual part weight without over-specifying.

Where the Airtac ACE Compact Cylinder ACE25X100SB Is Used
Jig Clamping on CNC Fixtures
Use the ACE25X100SB to clamp small aluminum parts in a CNC vise or fixture. The 245.4 N push at 0.5 MPa holds components firmly during milling, and the compact body fits under a low-profile guard.
Carton Ejection in Packaging Lines
In a carton erecting machine, this cylinder can push folded boxes out of a magazine. Its 100 mm stroke clears the box length, and the 206.2 N pull retracts the rod quickly for the next cycle.
Sorting Gate on a Conveyor
Mount the ACE25X100SB as a diverter gate on a small conveyor sorting line. The 25 mm bore provides enough force to redirect lightweight parcels, and the optional magnet lets you confirm the gate position with a CMSE switch.
Is the Airtac ACE Compact Cylinder ACE25X100SB the Right Cylinder?
When sizing, compare this 25 mm bore against a 20 mm bore (157.1 N push at 0.5 MPa) for lighter duty, or step up to a 32 mm bore (402.1 N push at 0.5 MPa) if you need nearly double the force. The 100 mm stroke is within the 150 mm standard maximum for this bore, so it ships as a standard item. Since the male rod thread (B code) is fitted, you can directly attach a rod-end accessory without an adapter.
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 ACE25X100SB 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. Operating pressure range is 0.15-1.0 MPa (22-145 psi), with a proof pressure of 1.5 MPa (215 psi).
The ACE25X100SB body is about 50% shorter than an ISO 15552 profile cylinder, so it installs in tight spaces like machine guarding or gantries. It has a fixed TPU bumper at both ends to absorb impact, and the optional -S magnet allows CMSE or DMSE switches for position feedback. The port is M5x0.8, and the rod is 10 mm with a male thread.
