Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X275-20B
The AirTAC ACEJ80~100 Adjustable Compact Cylinder ACEJ100X275-20B is a genuine double acting, double rod, adjustable stroke ISO 21287 compact air cylinder with a Ø100mm bore and 275mm stroke, 1/8" air ports and a hard-anodized aluminium body. Its short compact envelope saves about 50% of the mounting length of an ISO 15552 profile cylinder.

About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X275-20B
A double acting ISO 21287 compact cylinder with an adjustable extend stroke, the ACEJ100X275-20B pairs a 100 mm bore with a 275 mm stroke and a male-threaded 20 mm rod. At 0.5 MPa it pushes 3927 N and pulls 3769.9 N, and the theoretical ceiling is 800.9 kgf at 1.0 MPa. The stop screw trims the extend stroke anywhere in a 20 mm window, so the working range is 255-275 mm set on site with a screwdriver.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters when a 275 mm stroke must fit inside a press frame, gate or gantry. Air ports are 1/8" PT, speed runs 30-500 mm/s, and a fixed TPU bumper sits at both ends.

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 ACEJ100X275-20B Is Used
Clamping fixture for large castings
The male-threaded rod (B code) takes a custom clamp arm to hold engine blocks or pump housings during machining, with the stroke trimmed to the fixture depth via the stop screw.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X275-20B the Right Cylinder?
Remember the stop screw is a mechanical end stop only - on air loss the rod still drifts, so add a locking valve if the load must stay put.
This unit has no magnet because the -S code was not ordered; if CMSE or DMSE switches are needed later, specify ACEJ100X275-20SB instead. FA flange, LB foot and I/Y rod knuckles bolt straight to the ISO 21287 face.
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 ACEJ100X275-20B 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 pull to 5277.9 N; theoretical maximum is 800.9 kgf at 1.0 MPa. The -20 code gives a 20 mm adjustment window: an external stop screw shortens the 275 mm extend stroke to any value from 255 to 275 mm. It is a mechanical end stop, not a mid-stroke lock, so the rod can drift if air is lost.
The ISO 21287 body is about 50% shorter in mounting length than an ISO 15552 profile cylinder, so a 275 mm stroke fits where a full-length profile cylinder will not. FA flange and LB foot mounts plus I and Y rod knuckles bolt directly to the standard face, and the fixed TPU bumper at each end absorbs end-of-stroke shock. Position sensing needs the optional -S magnet code, which enables CMSE or DMSE switches; this model without -S carries no magnet.
