About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X80-20B
The ACEJ100X80-20B is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 80 mm stroke by up to 20 mm on site, giving a usable range of 60-80 mm without changing the cylinder.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so heavy clamping fits inside tight press frames and guarding. A fixed TPU bumper at each end absorbs end-of-stroke energy, and the hard-anodized aluminium body with an S45C hard-chrome plated rod stands up to high-cycle production. Note that no magnet is fitted on this model; the optional -S code is required if CMSE / DMSE switches are wanted later.

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 ACEJ100X80-20B Is Used
Small press and crimping stations
With about 2356 N of practical working force and a male-threaded 20 mm rod, this cylinder drives bench-top crimping, staking and marking heads where a full-length profile cylinder will not fit in the frame.
Pallet and container push-off arms
On conveyor transfer carts, the short body mounts inside the cart frame with an LB foot bracket, and the stop screw trims the extend stroke so cartons stop at the same lane position every cycle.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X80-20B the Right Cylinder?
At 0.5 MPa this bore pushes 3927 N; the next size down, bore 80, manages 2513.3 N, while bore 125 reaches 6135.9 N, so choose the 100 mm bore when your clamp or press load sits between roughly 2500 N and 6000 N. If the -20 window is too coarse, the same cylinder is orderable with 10/30/40/50/75/100 mm adjustment windows. Mount with FA flange or LB foot brackets on the ISO 21287 face, add I or Y rod knuckles for the male thread, and remember the adjuster is a mechanical end stop only: on air loss the piston drifts, so it is not a load-holding brake. Order the -S variant if position detection with CMSE / DMSE switches is planned.
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 ACEJ100X80-20B FAQ
The -20 code sets a 20 mm adjustment window: an external stop screw shortens the 80 mm extend stroke to any length from 60 to 80 mm. It is a mechanical end stop for the extend stroke only, not a mid-stroke lock, so the piston still drifts if air is lost. Operating range is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, air filtered to 40 um.
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, S45C hard-chrome rod and fixed TPU bumpers at both ends. This unit has no magnet fitted; the optional -S code adds one so CMSE / DMSE switches can be mounted in the body slots. Mounting is via FA flange or LB foot brackets plus I/Y rod knuckles on the male thread, and the 1/8" port thread is PT as standard (G on request). For outline dimensions, confirm from datasheet.
