About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X75-20B
A double acting ISO 21287 compact cylinder with a 100 mm bore and a 75 mm stroke that an external stop screw trims by up to 20 mm, giving a usable extend range of 55-75 mm. At 0.5 MPa it pushes 3927 N and pulls 3769.9 N, rising to 5497.8 N at 0.7 MPa. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so heavy clamping or pressing heads fit into gantries and guarding where a full-length body cannot go.
The hard-anodized aluminium body carries a 20 mm S45C hard-chrome rod with a male thread (the B code), fed through a 1/8" PT port. A fixed TPU bumper at each end absorbs end-of-stroke energy, and speed runs 30-500 mm/s at 0.15-1.0 MPa (22-145 psi).

Specifications follow the official AirTAC ACE-series (ISO 21287) datasheet. Body: hard-anodized aluminium alloy; piston rod: S45C carbon steel with hard-chrome plating. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G. A built-in magnet is OPTIONAL — add the -S code to fit CMSE / DMSE position sensors.
Theoretical Output Force (Ø100mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 3770 N |
| 0.7 MPa | 5278 N |
| Max (@1.0 MPa) | 769 kgf |
ACEJ is double-rod: the rear rod that carries the stroke adjuster exits the rear cover, so both piston faces lose rod area. The rod-side (annular) area is used for both directions (conservative).

Where the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X75-20B Is Used
Press-fit of bearing housings
With about 240 kg of usable force at 0.5 MPa, the 100 mm bore seats bearings into aluminium housings on a small assembly press, and the 55-75 mm adjustable window lets one cylinder serve several housing depths.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X75-20B the Right Cylinder?
Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock, so the rod still drifts if air is lost and a separate holding method is needed for suspended loads.
FA flange or LB foot mounts bolt to the ISO 21287 face, and I or Y rod knuckles suit the male rod thread. If position feedback is needed later, order the -S variant, which adds the magnet that lets CMSE / DMSE switches be fitted; this model without the S code carries no magnet.
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 ACEJ100X75-20B FAQ
At 0.5 MPa it pushes 3927 N and pulls 3769.9 N; at 0.7 MPa push rises to 5497.8 N, and the theoretical maximum is 800.9 kgf at 1.0 MPa. The -20 code sets a 20 mm adjustment window: an external stop screw shortens the 75 mm extend stroke on site, so the usable range is 55-75 mm. It cannot lengthen the stroke past 75 mm, and the stop is an end stop only, not a load-holding brake. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, air filtered to 40 um, temperature -20 to +70 C.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits where a full-length body will not. FA flange and LB foot mounts plus I/Y rod knuckles bolt to the standard face, and the B code gives a male rod thread. A fixed TPU bumper at each end absorbs end-of-stroke energy. Position sensing requires the optional -S magnet, which allows CMSE or DMSE switches; this model has no S code, so no magnet and no sensor mounting is possible.
