About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X75-50B
The ACEJ100X75-50B is a double acting ISO 21287 compact cylinder with a 100 mm bore and a 75 mm stroke that an external stop screw can trim by up to 50 mm, giving a usable extend range of 25-75 mm. At 0.5 MPa it pushes with 3927 N and pulls with 3769.9 N, rising to 5497.8 N at 0.7 MPa - a force class suited to heavy clamping and press-fit work. The male (B code) rod thread bolts directly to tooling without an intermediate nut.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so a 100 mm bore fits inside presses, weld fixtures and gantries that cannot accept a full-length body. The hard-anodized aluminium body carries an S45C hard-chrome rod, fixed TPU bumpers absorb end-of-stroke energy, and the optional -S magnet enables CMSE / DMSE switches - without -S no magnet is fitted.

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 ACEJ100X75-50B Is Used
Weld fixture clamping
Heavy sheet-metal weld jigs use the 100 mm bore to hold large panels; the short body fits between fixture rails where a full-length ISO 15552 profile cylinder would not.
Pallet gate and stopper actuation
Conveyor lift-and-locate gates for 150-200 kg pallet loads use the vertical-lift margin of about 200 kg, with FA flange mounting and the optional -S magnet for CMSE switch confirmation.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X75-50B the Right Cylinder?
The -50 window trims the 75 mm extend stroke down to 25 mm on site; remember the stop screw is a mechanical end stop, not a mid-stroke lock, so the rod still drifts if air is lost. Mounting: FA flange or LB foot bolt to the ISO 21287 face, with I / Y rod knuckles for the male-threaded rod. If position feedback is needed, order the -S code so CMSE / DMSE switches can be 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 ACEJ100X75-50B FAQ
At 0.5 MPa it pushes 3927 N and pulls 3769.9 N; at 0.7 MPa push is 5497.8 N and pull 5277.9 N; theoretical maximum is 800.9 kgf at 1.0 MPa. The -50 code is a 50 mm adjustment window: an external stop screw shortens the 75 mm extend stroke to any value from 25 to 75 mm. It is a mechanical end stop only - on air loss the piston drifts, so it never holds a load. Operating range is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, port 1/8" PT, male rod thread.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so a 100 mm bore fits tight presses and gantries. Fixed TPU bumpers absorb end-of-stroke energy at both ends, and FA flange or LB foot mounting bolts to the standard ISO 21287 face. Position sensing requires the optional -S magnet code - without it no magnet is fitted and no CMSE / DMSE switch can be mounted.
