Airtac ACE Compact Cylinder ACE25X45SB
The AirTAC Airtac ACE Compact Cylinder ACE25X45SB is a genuine double acting ISO 21287 compact air cylinder with a Ø25mm bore and 45mm 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 ACE25X45SB
This AirTAC ACE25X45SB is a double acting ISO 21287 compact cylinder that extends and retracts its 10 mm rod with air pressure on both strokes. With a 25 mm bore it delivers 245.4 N of push force and 206.2 N of pull force at 0.5 MPa, so it suits light assembly and clamping tasks where space is tight.
The hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder, letting it fit inside machine guards and compact jigs. The optional -S magnet is fitted here, so CMSE or DMSE reed and solid-state switches can mount directly to sense the piston position. For real work, plan on about 15 kg of safe vertical lift at 0.5 MPa, which is roughly 60% of the rated push force, leaving a margin for friction and side loads.

Where the Airtac ACE Compact Cylinder ACE25X45SB Is Used
Fixture Clamping
Clamp small parts in a CNC vise or workholding fixture where the 45 mm stroke and 245.4 N push at 0.5 MPa provide firm holding without taking up much space.
Label Applicator
Drive a label applicator head in a packaging line, using the compact body to fit between guide rails and the magnet to confirm each cycle with a CMSE switch.
Guard Door Interlock
Actuate a small safety guard door on a benchtop press, where the short stroke and 206.2 N pull force retract the door reliably and the TPU bumper softens the stop.
Is the Airtac ACE Compact Cylinder ACE25X45SB the Right Cylinder?
For lighter duty, the 20 mm bore ACE20X45S pushes 157.1 N at 0.5 MPa, while stepping up to a 32 mm bore ACE32X45S gives 402.1 N push. This 25 mm version balances force and compactness, and the male rod thread (B) simplifies mounting with rod-end accessories. The fixed TPU bumper absorbs end-of-stroke impact, but it does not hold a load if air pressure is lost, so add a rod lock or pilot check valve for vertical holding. The M5x0.8 port suits small-bore fittings, and the magnet allows position sensing with CMSE switches.
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 ACE25X45SB FAQ
At 0.5 MPa, push force is 245.4 N and pull force is 206.2 N. At 0.7 MPa, push rises to 343.6 N and pull to 288.6 N. The theoretical maximum force at 1.0 MPa is 50.1 kgf. Operating pressure range is 0.15-1.0 MPa (22-145 psi), and proof pressure is 1.5 MPa (215 psi).
The ACE25X45SB body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into machine guards, gantries, and fixtures where a full-length cylinder would not. It uses a fixed TPU bumper at both ends to absorb impact, and the optional -S magnet allows CMSE or DMSE switches to detect piston position. The M5x0.8 port and male rod thread simplify integration.
