Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X15-10B
The AirTAC Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X15-10B is a genuine double acting, adjustable stroke ISO 21287 compact air cylinder with a Ø16mm bore and 15mm 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 ACEJ16X15-10B
A double acting compact cylinder built to ISO 21287, the ACEJ16X15-10B pairs a 16 mm bore with a 15 mm stroke that an external stop screw trims on site. The -10 code opens a 10 mm adjustment window, so the extend stroke can be set anywhere between 5 and 15 mm without swapping parts. At 0.5 MPa it pushes 100.5 N and pulls 75.4 N, rising to 140.7 N at 0.7 MPa. The hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into small pick-and-place heads and test fixtures a full-length body cannot reach.
Practical sizing: keep real work to roughly 60 N at 0.5 MPa, which is about 6 kg of vertical lift with a margin to spare. The rod carries a male thread (the B code) for direct nut fixing, and the fixed TPU bumper at each end absorbs end-of-stroke shock. Air supply is 0.15-1.0 MPa (22-145 psi), speed runs 30-500 mm/s, and the port is M5x0.8. If position feedback is needed later, order the -S variant with the optional magnet for CMSE / DMSE switches; this model has no magnet fitted.

Theoretical Output Force (Ø16mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 101 N | 75 N |
| 0.7 MPa | 141 N | 106 N |
| Max (@1.0 MPa) | 21 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X15-10B Is Used
Micro press fitting
The 5-15 mm adjustable window and 100.5 N push at 0.5 MPa seat small bearings or terminals in electronics assemblies without over-travel.
Semiconductor wafer lift
With about 6 kg of usable vertical lift capacity, the short body lifts small carriers inside tight tool chambers where a profile cylinder will not fit.
Lab sample indexing
Male rod thread and 30-500 mm/s speed make it easy to bolt onto sample trays that need a repeatable 5-15 mm push between stations.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X15-10B the Right Cylinder?
At 100.5 N push (0.5 MPa) this 16 mm bore suits light clamping and small part transfer; step down to a 12 mm bore (56.5 N) for tiny fixtures or up to a 20 mm bore (157.1 N) when the load creeps higher. Remember the stop screw only shortens the extend stroke and is not a mid-stroke lock, so the rod still drifts if air is lost. Mount with FA flange or LB foot brackets on the ISO 21287 face, and add the -S magnet code if CMSE / DMSE sensing will ever be required.
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 ACEJ16X15-10B FAQ
At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa those rise to 140.7 N and 105.6 N, with a theoretical maximum of 20.5 kgf at 1.0 MPa. The -10 code gives a 10 mm adjustment window: an external stop screw shortens the 15 mm extend stroke to any setting between 5 and 15 mm. It is a mechanical end stop only, not a mid-stroke lock, so the rod still drifts on air loss.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, S45C hard-chrome rod and fixed TPU bumpers at both ends. Sensing is not included on this model: the magnet is the optional -S code, so order ACEJ16X15-10SB if you want CMSE / DMSE switches to work. Mounting is via FA flange or LB foot on the standard ISO 21287 face, with PT ports at M5x0.8.
