About the Airtac ACE Compact Cylinder ACE25X35S
This AirTAC ACE25X35S is a double acting ISO 21287 compact cylinder with a 25 mm bore and 35 mm stroke. Its short, hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits into tight machine frames and guarding where a longer cylinder would not. The S45C piston rod is hard-chrome plated for wear resistance, and a fixed TPU bumper at each end softens the stop.
At 0.5 MPa this unit delivers 245.4 N of push force and 206.2 N of pull force, which translates to a practical vertical lift of about 12.5 kg with a 2:1 safety margin. Because the -S magnet is fitted, you can mount CMSE or DMSE reed or solid-state switches directly on the body for position sensing. The M5x0.8 port and M6x1.0 female rod thread make it easy to plumb and connect to standard fixtures.

Where the Airtac ACE Compact Cylinder ACE25X35S Is Used
Compact Jig Clamping
Use the ACE25X35S to clamp small parts in a CNC fixture where the 50% shorter body lets you fit more clamps in a tight work envelope, with the 245.4 N push force holding thin-walled components securely.
Label Applicator Press
In a packaging line, this cylinder can press labels onto small cartons with a 35 mm stroke, and the optional -S magnet lets a DMSE sensor confirm each press cycle for quality control.
Conveyor Stop Gate
Mount the ACE25X35S on a light conveyor to raise a stop gate for small boxes, using the 206.2 N retract force to pull the gate down quickly, and the compact body to fit under the conveyor frame.
Is the Airtac ACE Compact Cylinder ACE25X35S the Right Cylinder?
For a lighter duty application, the ACE20X35 offers 157.1 N push at 0.5 MPa, while stepping up to the ACE32X35 gives you 402.1 N push at the same pressure. Choose this 25 mm bore when you need a balance of force and compact size, and remember that a plain ACE cylinder does not hold its position if air pressure is lost - use a rod lock or pilot check valve for load holding. The fitted magnet allows CMSE or DMSE sensors to confirm the rod position, and the ISO 21287 face accepts FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, and FTC mounting brackets.
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 ACE25X35S 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. The operating pressure range is 0.15-1.0 MPa (22-145 psi), and the speed range is 30-500 mm/s.
The ACE25X35S has a short body that saves about 50% of the mounting length of an ISO 15552 profile cylinder, making it ideal for tight spaces. It uses a fixed TPU bumper at both ends to absorb impact, and the -S magnet allows CMSE or DMSE sensors to be mounted for position detection. The M5x0.8 port is standard for this bore size.
