The AirTAC Airtac ACE Compact Cylinder ACE25X45 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.
This AirTAC ACE25X45 is a double acting compact cylinder built to ISO 21287, with a 25 mm bore and 45 mm stroke. At 0.5 MPa it delivers 245.4 N of push force and 206.2 N of pull force, 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 fixed TPU bumper at each end absorbs impact, and the M5x0.8 port keeps installation simple. For a safe working load, plan for about 147 N of real work at 0.5 MPa, which is roughly 15 kg lifted vertically with a 2:1 safety margin.

Specifications follow the official AirTAC ACE-series (ISO 21287) datasheet. Body: hard-anodized aluminium alloy; piston rod: S45C carbon steel with hard-chrome plating. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G. A built-in magnet is OPTIONAL — add the -S code to fit CMSE / DMSE position sensors.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 245 N | 206 N |
| 0.7 MPa | 344 N | 289 N |
| Max (@1.0 MPa) | 50 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

ACE-family variants: ACE (double acting), ASE / ATE (single acting push / pull), ACED (double rod), ACEJ (adjustable stroke), TACE / TACED (non-rotating twin-guide yoke). Mounting accessories: FA / FB flange, LB foot, CA / CB clevis, CR, SDB pivot, FTC; plus I and Y knuckles. Thread PT (blank) / G.
Use in a CNC fixture to clamp small aluminum parts during drilling, with 245.4 N push holding the workpiece firmly at 0.5 MPa.
Drive a tab-folding mechanism on a packaging line, where the 45 mm stroke cycles at up to 500 mm/s to fold carton flaps.
Operate a small safety guard latch on a machine, using the compact body to fit within the guard frame and the 206.2 N pull to retract the latch.
For a lighter duty, the ACE20X45 offers 157.1 N push at 0.5 MPa, while stepping up to the ACE32X45 gives 402.1 N push. This 25 mm bore model balances force and footprint for medium-light applications. Since the stroke is 45 mm, well under the 150 mm maximum standard, it is a standard off-the-shelf unit. The female M6x1.0 rod thread accepts standard attachments, and the M5x0.8 port works with common fittings. This unit has no magnet, so order the -S option if you need to mount CMSE or DMSE sensors.
Quick checklist
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 is 50.1 kgf at 1.0 MPa. Operating pressure range is 0.15-1.0 MPa (22-145 psi).
Yes, it is an ISO 21287 compact cylinder with a body about 50% shorter than an ISO 15552 profile cylinder. It has a fixed TPU bumper at both ends. This model has no magnet, so you cannot mount sensors unless you order the optional -S code, which adds a magnet for CMSE or DMSE switches.
