Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X15-10
The AirTAC Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X15-10 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 ACEJ16X15-10
The ACEJ16X15-10 is a double acting ISO 21287 compact cylinder with an adjustable extend stroke. Its 16 mm bore delivers 100.5 N push and 75.4 N pull at 0.5 MPa, rising to 140.7 N push at 0.7 MPa, with a theoretical peak of 20.5 kgf at 1.0 MPa. The hard-anodized aluminium body pairs with an 8 mm S45C hard-chrome rod, and 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 -10 code gives a 10 mm adjustment window: an external stop screw trims the 15 mm extend stroke down to as little as 5 mm on site, no disassembly needed. Plan on roughly 60 N (about 6 kg) of real working force at 0.5 MPa, which lifts about 5 kg vertically with a 2:1 margin. A fixed TPU bumper at each end absorbs end-of-stroke shock, speed runs 30-500 mm/s, and the optional -S magnet enables CMSE / DMSE switches when ordered.

Where the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X15-10 Is Used
Small-part ejection
A 5-15 mm adjustable stroke is ideal for ejecting stamped terminals or plastic caps from shallow cavities, with about 60 N of usable push at 0.5 MPa.
Fixture clamping
Clamps PCBs or small machined brackets inside tight jigs where the short ISO 21287 body fits where a full-length profile cylinder cannot.
Indexing on compact modules
Short push-and-return moves on rotary indexing tables; order the -S magnet to add CMSE / DMSE end-position sensing.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X15-10 the Right Cylinder?
At 100.5 N push (0.5 MPa) this 16 mm bore suits light clamping and positioning; step down to a 12 mm bore (56.5 N) for gentler loads or up to a 20 mm bore (157.1 N) when parts weigh more. Remember the stop screw only sets the extend end position - it is not a mid-stroke lock, so the rod can drift if air is lost. Choose the B code for a male rod thread, FA or LB mounting to bolt into standard fixtures, and add the -S magnet if CMSE / DMSE position sensing is planned.
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 ACEJ16X15-10 FAQ
Push is 100.5 N and pull 75.4 N at 0.5 MPa; at 0.7 MPa push rises to 140.7 N and pull to 105.6 N, with a theoretical maximum of 20.5 kgf at 1.0 MPa. It is double acting with a 10 mm adjustment window on the 15 mm stroke (usable 5-15 mm), port M5x0.8, female M4x0.7 rod thread, operating pressure 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, and temperature -20 to +70 C.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with FA flange or LB foot mounting and I/Y rod knuckles available. Position sensing requires the optional -S magnet code; without it no magnet is fitted, so CMSE or DMSE switches will not trigger. A fixed TPU bumper at each end absorbs end-of-stroke impact.
