About the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X35-10S
The ACEJ16X35-10S is a double acting ISO 21287 compact cylinder with a 16 mm bore and a 35 mm stroke that an external stop screw trims on site: the -10 code gives a 10 mm window, so the extend stroke is set anywhere between 25 and 35 mm without swapping the cylinder. At 0.5 MPa it pushes 100.5 N and pulls 75.4 N, rising to 140.7 N push at 0.7 MPa, with a theoretical ceiling of 20.5 kgf at 1.0 MPa. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into slim fixtures a full-length body cannot reach.
This model carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be clipped to the body for end-of-stroke signalling. A fixed TPU bumper at each end absorbs end-of-stroke energy, and the hard-anodized aluminium body with an S45C hard-chrome plated 8 mm rod stands up to continuous cycling. As a rule of thumb, plan on roughly 60 N (about 6 kg of vertical lift with a 2:1 margin) of real work at 0.5 MPa rather than the full rating.

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 ACEJ16X35-10S Is Used
Fixture clamping on small CNC jigs
The 25-35 mm adjustable extend stroke lets a machinist dial in clamp travel per fixture, and the 100.5 N push at 0.5 MPa suits light clamping of aluminium brackets.
Position-verified ejection on assembly lines
With the -S magnet fitted, CMSE or DMSE switches confirm the 8 mm rod has fully extended before the next part is released, at speeds of 30-500 mm/s.
Compact press-fit of connectors
The short body, about 50% shorter in mounting length than an ISO 15552 profile cylinder, fits inside a bench-top press head where a 140.7 N push at 0.7 MPa seats small terminals.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ16X35-10S the Right Cylinder?
Size up if 100.5 N push at 0.5 MPa is marginal: the 20 mm bore delivers 157.1 N in the same short body. Size down to the 12 mm bore (56.5 N) only for light indexing. The stop screw shortens the extend stroke only - it is a mechanical end stop, not a mid-stroke lock, so the rod still drifts if air is lost. FA flange, LB foot and I/Y rod knuckles bolt to the ISO 21287 face; the -S magnet is already fitted on this variant for CMSE / DMSE switch mounting.
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 ACEJ16X35-10S FAQ
At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa, 140.7 N push and 105.6 N pull; theoretical maximum is 20.5 kgf at 1.0 MPa. The -10 code sets a 10 mm adjustment window: an external stop screw shortens the 35 mm extend stroke to as little as 25 mm. It is a mechanical end stop only - on air loss the piston drifts, so it is not a load-holding brake. Operating range is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, port M5x0.8, female rod thread M4x0.7.
It is an ISO 21287 compact cylinder whose hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder. A fixed TPU bumper at each end absorbs end-of-stroke energy. This variant includes the optional -S magnet, so CMSE / DMSE reed or solid-state switches mount in the body slots. FA flange, LB foot and I/Y rod knuckles bolt straight to the ISO 21287 mounting face; PT ports are standard and G threads can be ordered.
