Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X40-10B
The AirTAC ACEJ80~100 Adjustable Compact Cylinder ACEJ80X40-10B is a genuine double acting, double rod, adjustable stroke ISO 21287 compact air cylinder with a Ø80mm bore and 40mm 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 ACEJ80X40-10B
A double acting ISO 21287 compact cylinder with a 40 mm stroke that can be trimmed on site by up to 10 mm, giving a usable extend range of 30-40 mm. The 80 mm bore pushes 2513.3 N and pulls 2356.2 N at 0.5 MPa, rising to 3518.6 N at 0.7 MPa. The male rod thread (B code) on the 20 mm rod bolts straight to external tooling, and the 1/8" port feeds the high flow this bore needs at 30-500 mm/s.
The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into presses, clamping fixtures and gantries where a full-length body will not fit. A hard-anodized aluminium body with an S45C hard-chrome plated rod resists wear, and a fixed TPU bumper at each end absorbs end-of-stroke shock.

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 ACEJ80X40-10B Is Used
Fixture clamping on a machining line
Clamps steel housings against a jig with about 1500 N of usable force at 0.5 MPa; the short body fits under the fixture lid where a full-profile cylinder cannot.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X40-10B the Right Cylinder?
Note that the stop screw only shortens the extend stroke within the 10 mm window; it is a mechanical end stop, not a mid-stroke lock, so the rod will drift if air is lost. FA flange or LB foot mountings bolt to the ISO 21287 face, and if you need position sensing, order the -S variant so CMSE / DMSE switches can be used - this model 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 ACEJ80X40-10B FAQ
At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa push is 3518.6 N and pull 3298.7 N, with a theoretical maximum of 512.6 kgf at 1.0 MPa. The -10 code is a 10 mm adjustment window: an external stop screw shortens the 40 mm extend stroke on site, so the usable range is 30-40 mm. It cannot lengthen the stroke past 40 mm, and the stop is not a load-holding brake - on air loss the piston still drifts. Operating pressure is 0.15-1.0 MPa (22-145 psi) and speed is 30-500 mm/s.
The ISO 21287 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. FA flange and LB foot mountings plus I and Y rod knuckles bolt to the standard face. Position sensing requires the optional -S magnet code, which enables CMSE / DMSE switches; this model (no S code) carries no magnet, so no switch can be mounted on it. Rod end is male thread and the port is 1/8" PT.
