About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X125-10
The ACEJ100X125-10 is a double acting ISO 21287 compact cylinder with a 100 mm bore and a 125 mm stroke that an external stop screw can trim by up to 10 mm, giving a usable extend range of 115-125 mm. At 0.5 MPa it pushes with 3927 N and pulls with 3769.9 N, rising to 5497.8 N on push at 0.7 MPa, with a theoretical ceiling of 800.9 kgf at 1.0 MPa. A practical rule of thumb: plan for roughly 2356 N of real work at 0.5 MPa, which corresponds to lifting about 200 kg vertically with a 2:1 margin.
The hard-anodized aluminium body with an S45C hard-chrome-plated rod saves about 50% of the mounting length of an ISO 15552 profile cylinder, so this heavy-thrust cylinder fits presses, gantries and clamping fixtures where a full-length body will not go. A fixed TPU bumper at each end absorbs end-of-stroke impact, and FA flange or LB foot mounts bolt straight to the ISO 21287 face. Note that the stop screw is a mechanical end stop only: on air loss the piston still drifts, so it never holds a load mid-stroke.

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 ACEJ100X125-10 Is Used
Pneumatic press and staking
The 3927 N push at 0.5 MPa (about 200 kg vertical lift with margin) suits staking rivets, pressing bearings and light forming in a short-stroke press frame.
Fixture clamping on machining centers
The 115-125 mm adjustable extend range lets a machinist dial in clamp position on jigs for cast housings, with the FA flange bolting to a standard ISO 21287 face.
Pallet gate and lift-assist actuation
Compact 100 mm bore body drives heavy gate arms and lift-assist links on packaging lines where a full-length profile cylinder cannot fit behind the guard.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X125-10 the Right Cylinder?
At this force class, step down to a 63 mm bore (1558.6 N push at 0.5 MPa) if your load is under about 150 kg, or step up to a 125 mm bore (6135.9 N push at 0.5 MPa) for presses needing over 500 kgf of theoretical force. Choose the -10 window only if your final stroke is already known within 10 mm; wider windows of 20 to 100 mm exist for on-site tuning. The rod end here is female M12x1.75 with a PT 1/8" port. If you need position feedback, order the -S variant so CMSE or DMSE switches can ride the body; this code has no magnet fitted.
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 ACEJ100X125-10 FAQ
Push is 3927 N and pull is 3769.9 N at 0.5 MPa; at 0.7 MPa push reaches 5497.8 N and pull 5277.9 N, with a theoretical maximum of 800.9 kgf at 1.0 MPa. Operating pressure is 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, fluid air filtered to 40 um. The extend stroke is 125 mm, trimmable down to 115 mm via the stop screw, with a fixed TPU bumper at both ends.
It is an ISO 21287 compact cylinder: hard-anodized aluminium body, S45C hard-chrome-plated 20 mm rod, female M12x1.25-class rod thread per datasheet (this code is female M12x1.75), 1/8" PT ports, and FA/LB mounting options. The body saves about 50% of the mounting length of an ISO 15552 profile cylinder. Sensors are not possible on this code because no magnet is fitted; order the optional -S magnet version to enable CMSE or DMSE switches.
