About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X30-20B
A double acting ISO 21287 compact cylinder, the ACEJ80X30-20B pairs an 80 mm bore with a 30 mm stroke that an external stop screw trims on site: the -20 code gives a 20 mm window, so the usable extend range is 10-30 mm. At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa those rise to 3518.6 N and 3298.7 N, with a theoretical ceiling of 512.6 kgf at 1.0 MPa. The hard-anodized aluminium body carries magnet slots, and the S45C hard-chrome plated 20 mm rod ends in a male thread (the B code).
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight press fixtures and guarded gantries. Air is filtered to 40 um, pressure runs 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and a fixed TPU bumper sits at both ends. This unit has no magnet; order the optional -S code if CMSE / DMSE switch sensing is needed.

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 ACEJ80X30-20B Is Used
Clamping on a CNC fixture
Short-body footprint fits inside machine guards where a full-length ISO 15552 profile cylinder will not; the male rod thread takes standard knuckle fittings.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X30-20B the Right Cylinder?
Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock - on air loss the piston still drifts, so add a separate holding valve for suspended loads. FA flange, LB foot and FTC brackets plus I/Y rod knuckles bolt to the ISO 21287 face; PT ports are standard and G is optional. If position feedback matters, order the -S variant to enable CMSE / DMSE switches.
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 ACEJ80X30-20B FAQ
The -20 code sets a 20 mm adjustment window: an external stop screw shortens the 30 mm extend stroke to any value from 10 to 30 mm. It is a mechanical end stop only - it never holds a load on air loss.
The ISO 21287 compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium barrel, S45C hard-chrome 20 mm rod and fixed TPU bumpers at both ends. This model has no magnet; the optional -S code adds one so CMSE / DMSE switches can be mounted. FA flange, LB foot, FTC brackets and I/Y rod knuckles fit the standard ISO 21287 face; ports are 1/8" PT (G optional), pressure 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s.
