Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X55-30B
The AirTAC ACEJ80~100 Adjustable Compact Cylinder ACEJ80X55-30B is a genuine double acting, double rod, adjustable stroke ISO 21287 compact air cylinder with a Ø80mm bore and 55mm stroke, 1/8" air ports and a hard-anodized aluminium body.

About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X55-30B
A double acting ISO 21287 compact cylinder, the ACEJ80X55-30B pairs an 80 mm bore with a 55 mm stroke that an external stop screw trims on site by up to 30 mm, giving a usable extend range of 25-55 mm. At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N, rising to 3518.6 N on the extend stroke at 0.7 MPa. The male rod thread (B code) on the 20 mm rod bolts straight into standard tooling.
The hard-anodized aluminium body with an S45C hard-chrome rod saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into presses, weld fixtures and gantries where a full-length body will not fit. A fixed TPU bumper at each end absorbs end-of-stroke shock, and the optional -S magnet enables CMSE / DMSE switches when ordered.

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 ACEJ80X55-30B Is Used
Weld fixture clamping
Short-body 80 mm bore clamps hold steel panels against locating pins inside tight weld cells, with the male rod thread picking up custom clamp arms.
Pallet gate and stopper actuation
In warehouse conveyor lines the cylinder lifts and drops heavy gate stops, and the 30 mm adjustment window dials in gate height without re-plumbing.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X55-30B the Right Cylinder?
If the job needs a non-rotating rod or a double rod, look at the TACE or ACED ranges instead. FA flange, LB foot and FTC brackets plus I/Y rod knuckles mount on the ISO 21287 face. The stop screw is a mechanical end stop only: on air loss the piston drifts, so it is not a mid-stroke lock. Order the -S code if position sensing is planned.
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 ACEJ80X55-30B 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 -30 code sets a 30 mm adjustment window, so the external stop screw trims the 55 mm extend stroke anywhere down to 25 mm. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, air filtered to 40 um, temperature -20 to +70 C, and the port is 1/8" PT.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and FA flange, LB foot and FTC brackets bolt to the standard face. A fixed TPU bumper at both ends absorbs end-of-stroke energy. Position sensing needs the optional -S magnet code; with -S ordered, CMSE / DMSE switches mount in the body slots, but without it no magnet is fitted.
