About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X75-40
A double acting ISO 21287 compact cylinder, the ACEJ80X75-40 pairs an 80 mm bore with a 75 mm stroke and a 40 mm adjustment window: an external stop screw trims the extend stroke on site anywhere from 35 to 75 mm, so one unit serves several fixture positions. At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N, rising to 3518.6 N at 0.7 MPa, with a theoretical ceiling of 512.6 kgf at 1.0 MPa.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into heavy gantries, press fixtures and machine guards where a full-length body will not fit. A hard-anodized aluminium body carries an S45C hard-chrome plated 20 mm rod, fixed TPU bumpers absorb end-of-stroke shock, and 1/8" ports feed air filtered to 40 um at 0.15-1.0 MPa (22-145 psi). This code has no magnet; order the optional -S version to enable CMSE / DMSE switches.

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 ACEJ80X75-40 Is Used
Weld cell clamp slide
The short body fits inside a robot weld cell guard where an ISO 15552 profile cylinder would overhang, with LB foot mounting on the fixture base.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X75-40 the Right Cylinder?
The 40 mm window suits stations where product sizes vary and the extend stroke must be set on site. Remember the stop screw is a mechanical end stop only: on air loss the piston drifts, so it is not a mid-stroke lock. FA flange, LB foot and I/Y rod knuckles bolt to the ISO 21287 face, and the female M12x1.75 rod thread accepts standard tooling plates.
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 ACEJ80X75-40 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 extend stroke is adjustable from 35 to 75 mm via the stop screw (-40 window), speed is 30-500 mm/s, operating pressure 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), temperature -20 to +70 C, ports 1/8" PT, rod thread female M12x1.75.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body, threaded aluminium covers, a hard-chrome plated S45C rod and fixed TPU bumpers at both ends that decelerate the piston at end of stroke. The body is about 50% shorter in mounting length than an ISO 15552 profile cylinder. This model has no magnet; the optional -S code adds one so CMSE / DMSE switches can sense position along the body slots.
