About the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X45-10SB
The ACEJ12X45-10SB is a double acting ISO 21287 compact cylinder with a 12 mm bore and a 45 mm stroke that an external stop screw trims on site by up to 10 mm, giving a usable extend range of 35-45 mm. The male rod thread (B code) suits external tooling, and the fitted -S magnet accepts CMSE / DMSE switches for end-position sensing.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into slim fixtures and guarded cells. The hard-anodized aluminium body carries a hard-chrome S45C rod, a fixed TPU bumper sits at both ends, and speed runs 30-500 mm/s at 0.15-1.0 MPa (22-145 psi).

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.
Theoretical Output Force (Ø12mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 42 N |
| 0.7 MPa | 59 N |
| Max (@1.0 MPa) | 9 kgf |
ACEJ is double-rod: the rear rod that carries the stroke adjuster exits the rear cover, so both piston faces lose rod area. The rod-side (annular) area is used for both directions (conservative).

Where the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X45-10SB Is Used
Small-parts ejection with position feedback
On a packaging line, the fitted magnet lets CMSE or DMSE switches confirm the 35-45 mm extend range, while the stop screw dials the eject distance to match shallow trays.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X45-10SB the Right Cylinder?
The 45 mm stroke sits inside the 50 mm max standard stroke for bore 12, so no made-to-order build is needed. The 10 mm window suits jobs where the final stop must be dialed in after installation - remember the stop screw only shortens the extend stroke and does not hold a load if air is lost. This model already carries the -S magnet and the B male rod thread; PT ports are standard, and FA flange or LB foot mounts bolt to the ISO 21287 face.
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 ACEJ12 Adjustable Compact Cylinder ACEJ12X45-10SB FAQ
Bore is 12 mm, stroke 45 mm adjustable within a 10 mm window (35-45 mm usable), rod 6 mm with male thread, port M5x0.8, speed 30-500 mm/s, pressure 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), temperature -20 to +70 C, air filtered to 40 um.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with FA flange, LB foot and I/Y knuckle accessories fitting the standard face. A fixed TPU bumper at each end absorbs end-of-stroke energy. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be clipped into the body slots to signal end positions.
