Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X70-40B
The AirTAC ACEJ80~100 Adjustable Compact Cylinder ACEJ100X70-40B is a genuine double acting, double rod, adjustable stroke ISO 21287 compact air cylinder with a Ø100mm bore and 70mm 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 ACEJ100X70-40B
A double acting ISO 21287 compact cylinder, the ACEJ100X70-40B pairs a 100 mm bore with a 70 mm stroke that an external stop screw trims anywhere in a 40 mm window, giving a usable extend range of 30-70 mm. At 0.5 MPa it pushes 3927 N and pulls 3769.9 N, and the hard-anodized aluminium body with an S45C hard-chrome plated 20 mm rod stands up to high-cycle press and clamp duty. Air supply is 0.15-1.0 MPa (22-145 psi) with speeds of 30-500 mm/s.
The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so this 100 mm bore fits press fixtures and gantries where a full-length body will not. The male rod thread (B code) bolts straight to standard tooling, and a fixed TPU bumper at each end absorbs 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 (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 ACEJ100X70-40B Is Used
Clamping on a machining line
Clamps heavy cast housings on a CNC fixture; the 30-70 mm adjustable range lets one cylinder serve several part variants without changing hardware.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X70-40B the Right Cylinder?
Remember the stop screw only shortens the extend stroke within the 40 mm window and is not a mid-stroke lock, so the rod still drifts if air is lost. Mount with FA flange or LB foot brackets on 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 ACEJ100X70-40B FAQ
At 0.5 MPa it pushes 3927 N and pulls 3769.9 N; at 0.7 MPa push is 5497.8 N and pull is 5277.9 N, with a theoretical maximum of 800.9 kgf at 1.0 MPa. The -40 code sets a 40 mm adjustment window: an external stop screw shortens the 70 mm extend stroke on site, so the usable range is 30-70 mm. It cannot lengthen the stroke past 70 mm, and the stop is a mechanical end stop, not a load-holding brake.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at both ends to absorb end-of-stroke energy. FA flange and LB foot brackets bolt to the standard ISO 21287 face. This model has no magnet, so no sensor can be mounted; order the -S version to enable CMSE / DMSE reed or solid-state switches.
