About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X80-75B
A double acting AirTAC compact cylinder built to ISO 21287, the ACEJ100X80-75B pairs a 100 mm bore with an 80 mm stroke and an external stop screw that trims the extend stroke anywhere in a 75 mm window, giving a usable range of 5-80 mm on site. 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 peak of 800.9 kgf at 1.0 MPa. The hard-anodized aluminium body and S45C hard-chrome plated 20 mm rod keep wear down in daily production duty.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so a 100 mm bore fits clamping stations and presses where a full-length profile body will not. The B code gives a male rod thread, the port is 1/8" PT, and fixed TPU bumpers absorb end-of-stroke shock at both ends. Speed range 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 | 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 ACEJ100X80-75B Is Used
Clamping heavy weld fixtures
On a robotic welding line the 100 mm bore holds large steel stampings in a fixture; the 5-80 mm adjustable range lets one cylinder serve different part heights without re-plumbing.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X80-75B the Right Cylinder?
Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock: if air is lost the piston still drifts, so add a separate holding valve for suspended loads. Mounting is via FA flange or LB foot on the ISO 21287 face, with I and Y rod knuckles available. This version has no magnet; order the -S code if you need CMSE or DMSE switch position sensing.
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 ACEJ100X80-75B FAQ
The -75 code is a 75 mm adjustment window: an external stop screw shortens the 80 mm extend stroke by up to 75 mm, so the working range is 5-80 mm. The stop is an end stop only and will not hold a load if air pressure is lost.
It is an ISO 21287 compact cylinder whose short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, 20 mm hard-chrome rod, fixed TPU bumpers at both ends and FA flange or LB foot mounting. Position sensing requires the optional -S magnet code; this model (no S) has no magnet, so CMSE or DMSE switches can only be used if you order the -S version.
