About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X25-20
A double acting ISO 21287 compact cylinder with a 100 mm bore and a short 25 mm stroke, the ACEJ100X25-20 delivers 3927 N of push force and 3769.9 N of pull at 0.5 MPa, rising to 5497.8 N at 0.7 MPa. An external stop screw trims the extend stroke on site anywhere within the ordered 20 mm window, so the usable extend range is 5-25 mm. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which makes it a strong fit for heavy clamping in tight press fixtures and weld cells.
The hard-anodized aluminium body carries a roller-burnished bore, and the 20 mm S45C piston rod is hard-chrome plated for long seal life. A fixed TPU bumper at each end absorbs end-of-stroke energy. Plan for roughly 2356 N (about 240 kg) of real work at 0.5 MPa instead of the full rating, and note the rod end is female M12x1.75 with a 1/8" PT port. Running speed is 30-500 mm/s over 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 | 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 ACEJ100X25-20 Is Used
Press-fit clamping of bearing housings
The 3927 N push at 0.5 MPa seats automotive bearing housings into housings on a short 5-25 mm extend range, ideal where a full-length cylinder will not fit behind the fixture.
Weld-cell fixture hold-down
Clamps steel stampings against weld fixtures with about 240 kg of usable working force, and the compact body tucks inside guard panels on the fixture plate.
Pallet-stacker gate actuation
Swings or locks heavy safety gates on AGV pallet movers, lifting roughly 200 kg vertically with margin, using LB foot mounting and the 1/8" PT air connection.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X25-20 the Right Cylinder?
At this bore size the step either way is large: a 80 mm bore pushes 2513.3 N at 0.5 MPa, while a 125 mm bore reaches 6135.9 N, so pick the 100 mm when your clamping or pressing load sits between those figures. For vertical lifting, the cylinder can hold about 200 kg with a 2:1 margin against its 3927 N push force, but remember the stop screw is an end stop only, not a mid-stroke lock, so the piston drifts if air is lost. Mount with FA flange or LB foot hardware on the ISO 21287 face, and if you need position sensing, order the -S variant so CMSE / DMSE switches can be used; this model 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 ACEJ100X25-20 FAQ
At 0.5 MPa it pushes 3927 N and pulls 3769.9 N; at 0.7 MPa those rise to 5497.8 N and 5277.9 N, with a theoretical maximum of 800.9 kgf at 1.0 MPa. The -20 code sets a 20 mm adjustment window: an external stop screw shortens the 25 mm extend stroke by up to 20 mm, giving a usable range of 5-25 mm. It is a mechanical end stop for the extend stroke only, not a load-holding lock.
The ISO 21287 compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, S45C hard-chrome rod and fixed TPU bumpers at both ends. FA flange and LB foot mounts bolt to the standard face. This model has no magnet; order the -S code to enable CMSE / DMSE reed or solid-state switches. Confirm outline dimensions from the datasheet.
