Airtac ACE Compact Cylinder ACE25X30S
The AirTAC Airtac ACE Compact Cylinder ACE25X30S is a genuine double acting ISO 21287 compact air cylinder with a Ø25mm bore and 30mm 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 ACE25X30S
This AirTAC ACE25X30S is a double acting compact cylinder that uses air to both extend and retract its 10 mm rod. It delivers 245.4 N of push force and 206.2 N of pull force at 0.5 MPa, with a theoretical maximum of 50.1 kgf at 1.0 MPa. The ISO 21287 short body is about 50% shorter than an ISO 15552 profile cylinder, fitting into tight machine frames and guarding where a full-length cylinder won't fit.
The 25 mm bore unit has a hard-anodized aluminium body and a hard-chrome plated S45C steel rod for wear resistance. This model includes the optional -S magnet, so you can mount CMSE or DMSE reed or solid-state switches for position sensing. For a real-world load estimate, plan for about 15 kg of safe vertical work at 0.5 MPa, which is roughly 60% of the rated push force converted to mass.

Where the Airtac ACE Compact Cylinder ACE25X30S Is Used
Small Part Clamping
Use the 245.4 N push force to clamp thin sheet metal or plastic components in a CNC fixture, holding them steady during drilling or routing operations.
Label Applicator Press
Drive a light labeling head to press labels onto boxes or bottles on a packaging line, with the 30 mm stroke providing the required travel for each cycle.
Jig Positioning Pin
Actuate a locating pin in a welding jig to position brackets before tacking. The compact body fits within the fixture envelope and the magnet confirms pin position via a CMSE switch.
Is the Airtac ACE Compact Cylinder ACE25X30S the Right Cylinder?
For a lighter duty, the ACE20X30S offers 157.1 N push at 0.5 MPa, while stepping up to the ACE32X30S gives you 402.1 N push at the same pressure. This ACE25X30S sits in the middle, suitable for moderate force applications like clamping small parts or actuating light guards. The M5x0.8 ports suit 4 mm or 6 mm tubing, and the female M6x1.0 rod thread accepts standard clevis or rod-end accessories.
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 ACE25X30S 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 at 1.0 MPa is 50.1 kgf. These figures are based on the 25 mm bore and 10 mm rod.
The ACE25X30S follows ISO 21287, a compact standard that saves about 50% of the mounting length compared to an ISO 15552 profile cylinder. This makes it ideal for tight spaces. It also features a fixed TPU bumper at both ends to absorb impact, and the optional -S magnet allows for CMSE or DMSE switch mounting.
