About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X100-40B
The ACEJ80X100-40B is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 100 mm stroke by up to 40 mm on site, giving a usable range of 60-100 mm without changing the cylinder. At the 80 mm bore it pushes 2513.3 N and pulls 2356.2 N at 0.5 MPa (3518.6 N / 3298.7 N at 0.7 MPa), with a theoretical maximum of 512.6 kgf at 1.0 MPa. The B code gives a male rod thread on the 20 mm rod, and the port is 1/8".
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into presses, clamping fixtures and machine frames where a full-length profile body will not fit. A hard-anodized aluminium body carries an S45C hard-chrome-plated rod, with a fixed TPU bumper at each end to absorb end-of-stroke energy.

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 ACEJ80X100-40B Is Used
Pallet lift-and-lower station
The pull force of 2356.2 N at 0.5 MPa retracts a scissor link that lowers 100 kg pallets onto a conveyor, while the short body fits under a low guard where an ISO 15552 profile cylinder would not.
Injection mold clamp slide
A male-threaded 20 mm rod (B code) drives a mold clamp slide on a plastics machine, with the stop screw set so the clamp seats at exactly 85 mm instead of the full 100 mm stroke.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X100-40B the Right Cylinder?
Remember the stop screw sets the extend stroke only - it is a mechanical end stop, not a mid-stroke lock, so the piston still drifts if air is lost. Bolt FA flange or LB foot mounts straight to the ISO 21287 face, and if you need position feedback, order the -S variant so CMSE / DMSE switches can be fitted; 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 ACEJ80X100-40B FAQ
Bore 80 mm, stroke 100 mm with a 40 mm adjustment window (usable extend range 60-100 mm). Operating pressure is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, air filtered to 40 um. The rod is 20 mm with a male thread (B code) and the port is 1/8".
An external stop screw shortens the extend stroke by up to 40 mm, so you can dial the 100 mm stroke down to 60 mm on the machine - it trims the stroke, it never extends it past 100 mm, and it acts as an end stop only, not a load-holding brake. Both ends carry a fixed TPU bumper that absorbs end-of-stroke energy. This model has no magnet; if you need CMSE or DMSE switches for end-of-stroke detection, order the -S code to have the optional magnet fitted. FA flange and LB foot mounts bolt to the standard ISO 21287 face.
