Airtac ACE Compact Cylinder ACE25X35B
The AirTAC Airtac ACE Compact Cylinder ACE25X35B is a genuine double acting ISO 21287 compact air cylinder with a Ø25mm bore and 35mm 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 ACE25X35B
This AirTAC ACE25X35B is a double acting compact cylinder built to ISO 21287, with a 25 mm bore and a 35 mm stroke. Its hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight machine frames and guarding where a full-length cylinder will not. The S45C carbon-steel rod is hard-chrome plated and has a male thread (B code) for direct coupling to a load.
At 0.5 MPa this unit pushes with 245.4 N and pulls with 206.2 N, so it suits light clamping and indexing tasks. A practical rule of thumb is to plan for about 60% of the rated push force, which gives roughly 15 kgf of safe working load at 0.5 MPa. The fixed TPU bumper at each end absorbs impact, but it does not lock or hold a load; if the air supply fails, the rod will drift.

Where the Airtac ACE Compact Cylinder ACE25X35B Is Used
Jig Clamping
Mount the ACE25X35B on a drill jig to clamp small brackets with 245.4 N of push force at 0.5 MPa. The short body keeps the fixture compact and the male rod thread allows a quick-release clamp pad.
Carton Tabbing
Use in a carton-erecting machine to push a glue tab into place. With a 35 mm stroke and 206.2 N pull force, it cycles at up to 500 mm/s to keep pace with a moderate packaging line.
Guard Door Interlock
Fit inside a machine guard frame to actuate a small interlock pin. The ISO 21287 compact body saves about half the mounting length of a profile cylinder, leaving room for hinges and sensors.
Is the Airtac ACE Compact Cylinder ACE25X35B the Right Cylinder?
For a 25 mm bore, the ACE25X35B delivers 245.4 N push at 0.5 MPa, which is a middle ground between the smaller ACE20 (157.1 N) and the larger ACE32 (402.1 N). Choose this model when you need more force than a 20 mm bore but have limited mounting space. The 35 mm stroke is well within the 150 mm maximum standard stroke for this bore, so no custom order is needed. Since this code has no S suffix, there is no magnet fitted, meaning CMSE or DMSE sensors cannot be used; order the -S version if you need position sensing. The male rod thread (B) simplifies attaching a clevis or rod end without a separate 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 ACE25X35B 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 proof pressure is 1.5 MPa (215 psi).
No, this ACE25X35B has no magnet because the code lacks the -S suffix. CMSE or DMSE reed or solid-state switches require the optional -S magnet, which must be ordered at purchase. Without the magnet, no sensor can detect the piston position. The cylinder itself has a fixed TPU bumper at both ends, not an adjustable cushion, and operates from -20 to 70 C.
