About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X120-100S
A double acting ISO 21287 compact cylinder with an adjustable extend stroke, the ACEJ100X120-100S pairs a 100 mm bore with a 120 mm stroke and a 100 mm trim window. At 0.5 MPa it pushes 3927 N and pulls 3769.9 N, rising to 5497.8 N on the extend side at 0.7 MPa, with a theoretical ceiling of 800.9 kgf at 1.0 MPa. The hard-anodized aluminium body carries a 20 mm S45C hard-chrome rod and a 1/8" PT port.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so a 100 mm bore fits presses and gantries that cannot house a full-length profile cylinder. A stop screw trims the extend stroke on site anywhere in the 20-120 mm range, and as a rule of thumb about 0.6 of the push force, roughly 2356 N, is a sensible working load - enough to lift about 240 kg vertically, or around 120 kg with a 2:1 margin. The fitted -S magnet accepts CMSE / DMSE switches, and a fixed TPU bumper at each end absorbs end-of-stroke shock.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3770 N |
| 0.7 MPa | 5498 N | 5278 N |
| Max (@1.0 MPa) | 801 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X120-100S Is Used
Pneumatic press and staking
The 3927 N extend force at 0.5 MPa suits staking, riveting and light forming on aluminium brackets, with the 20-120 mm trim window matching varied part heights on one fixture.
Palletizer push-off station
Short-body mounting plus 3769.9 N pull force lets the cylinder box-move palletized cartons on conveyor lines where a full-length profile cylinder will not fit behind the guard.
Die cart lift-and-lower assist
With about 240 kg of vertical lift equivalent at 0.5 MPa, the 100 mm bore raises mould inserts in toolrooms; the -S magnet and CMSE switches confirm top and bottom positions.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X120-100S the Right Cylinder?
Size against neighbours: a 80 mm bore gives 2513.3 N push at 0.5 MPa, while stepping up to 125 mm reaches 6135.9 N - pick the 100 mm when your load sits between those bands. If you need to lift a heavy die or fixture vertically, halve the lift figure again for margin. The stop screw is a mechanical end stop only; on air loss the piston drifts, so add a separate valve or lock for load holding. FA flange or LB foot mountings bolt to the ISO 21287 face, and this unit already carries the -S magnet for CMSE / DMSE switch position feedback.
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 ACEJ80~100 Adjustable Compact Cylinder ACEJ100X120-100S FAQ
At 0.5 MPa it pushes 3927 N and pulls 3769.9 N; at 0.7 MPa the figures are 5497.8 N push and 5277.9 N pull, with a theoretical maximum of 800.9 kgf at 1.0 MPa. It is double acting with an adjustable extend stroke of 20-120 mm via the stop screw, runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, with a 1/8" PT port and a 20 mm rod with M12x1.75 female thread.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight machine frames. A fixed TPU bumper at each end absorbs end-of-stroke energy. This model carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches mount directly in the body slots; FA flange and LB foot mountings plus I and Y rod knuckles bolt to the standard ISO 21287 face.
