Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X300-40B
The AirTAC ACEJ80~100 Adjustable Compact Cylinder ACEJ80X300-40B is a genuine double acting, double rod, adjustable stroke ISO 21287 compact air cylinder with a Ø80mm bore and 300mm 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 ACEJ80X300-40B
A double acting ISO 21287 compact cylinder with an adjustable extend stroke, the ACEJ80X300-40B pairs an 80 mm bore with a 300 mm stroke and a 20 mm hard-chrome S45C rod. At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N, so it belongs in the heavy clamp-and-lift class. The male rod thread (B code) bolts straight to your tooling, and the 1/8" port feeds the high flow this bore needs.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters when a 300 mm stroke has to fit inside a guarded weld cell or a deep press fixture. An external stop screw trims the extend stroke anywhere in the ordered 40 mm window, giving a usable 260-300 mm range set on site with a screwdriver.

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 (Ø80mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 2356 N |
| 0.7 MPa | 3299 N |
| Max (@1.0 MPa) | 481 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 ACEJ80X300-40B Is Used
Gate actuation on machinery guards
The short ISO 21287 body fits inside tight guard frames where a full-length ISO 15552 profile cylinder would overhang, driving sliding safety doors.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X300-40B the Right Cylinder?
Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock, so the rod still drifts if air is lost. Choose FA flange or LB foot mounting to match the fixture, and order the -S code only if you need the optional magnet for CMSE / DMSE switches; this version 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 ACEJ80X300-40B FAQ
At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa push rises to 3518.6 N (theoretical max 512.6 kgf at 1.0 MPa). The -40 code is a 40 mm adjustment window: an external stop screw shortens the 300 mm extend stroke on site, so the usable range is 260-300 mm. Operating pressure is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, with a fixed TPU bumper at both ends.
It is an ISO 21287 compact cylinder: hard-anodized aluminium body, S45C hard-chrome plated 20 mm rod, threaded aluminium covers, and a male rod thread (B code) on the end. The body saves about 50% of the mounting length of an ISO 15552 profile cylinder. Sensors need the optional -S magnet code; this model has no magnet, so CMSE / DMSE switches cannot be fitted unless you order -S. FA flange and LB foot mounts bolt to the standard ISO 21287 face.
