Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X30-30SB
The AirTAC Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X30-30SB is a genuine double acting, adjustable stroke ISO 21287 compact air cylinder with a Ø12mm 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 ACEJ12 Adjustable Compact Cylinder ACEJ12X30-30SB
A double acting ISO 21287 compact cylinder with an adjustable extend stroke, the ACEJ12X30-30SB pairs a 12 mm bore with a 30 mm stroke and a male rod thread. At 0.5 MPa it pushes 56.5 N and pulls 42.4 N, rising to 79.2 N push at 0.7 MPa. The external stop screw trims the extend stroke anywhere within the ordered 30 mm window, so one cylinder covers 0-30 mm on the bench without re-plumbing. The -S code means the magnet is fitted, so CMSE or DMSE reed and solid-state switches read end positions directly.
The hard-anodized aluminium body with an S45C hard-chrome rod saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight fixture plates and small guarding where a full-length body cannot. A fixed TPU bumper at each end absorbs end-of-stroke shock. In practice, plan on roughly 34 N (about 3.4 kg of push) of real work at 0.5 MPa, or lift about 2.9 kg vertically with a 2:1 margin. Speed range is 30-500 mm/s at 0.15-1.0 MPa (22-145 psi).

Where the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X30-30SB Is Used
Small-part ejection from plastic molds
The 56.5 N push at 0.5 MPa is enough to kick light molded caps or clips off a tool, and the 0-30 mm trim lets you match the exact ejection distance on the machine.
Presence checking on electronics assembly benches
With the -S magnet fitted, CMSE or DMSE switches confirm the board or connector is seated; the short body fits between bench fixtures where longer cylinders will not.
Adjustable stop pins on lab and test rigs
Set any extend position from 0 to 30 mm with the stop screw to locate small housings or PCBs against a fixture during manual inspection.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X30-30SB the Right Cylinder?
At this bore size the 56.5 N push at 0.5 MPa suits light clamping, sorting and sensor-check moves rather than heavy pressing. If your load needs more, step up to bore 16 (100.5 N push at 0.5 MPa) or bore 20 (157.1 N); if 56.5 N is generous, bore 12 is already the smallest in the range. Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock, so the rod can drift if air is lost. FA flange and LB foot mounts plus I/Y rod knuckles bolt to the ISO 21287 face, and the fitted -S magnet lets CMSE / DMSE switches report position. Ports are M5x0.8, rod thread is male, port thread PT.
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 ACEJ12X30-30SB FAQ
Bore 12 mm, stroke 30 mm adjustable within a 30 mm window. Push 56.5 N and pull 42.4 N at 0.5 MPa; push 79.2 N and pull 59.4 N at 0.7 MPa; theoretical maximum 11.5 kgf at 1.0 MPa. It is double acting, runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C, speed 30-500 mm/s, with a male rod thread and M5x0.8 ports.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits shallow fixture plates and tight guards. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be clipped to the body slot for end-of-stroke signals. FA flange, LB foot and FTC brackets plus I/Y rod knuckles mount on the standard face, and a fixed TPU bumper at each end absorbs end-of-stroke impact.
