Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X35-30B
The AirTAC ACEJ80~100 Adjustable Compact Cylinder ACEJ80X35-30B is a genuine double acting, double rod, adjustable stroke ISO 21287 compact air cylinder with a Ø80mm bore and 35mm 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 ACEJ80X35-30B
A double acting ISO 21287 compact cylinder, the ACEJ80X35-30B pairs an 80 mm bore with a 35 mm stroke that an external stop screw trims on site within the ordered 30 mm window, giving a usable extend range of 5-35 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 is about 50% shorter in mounting length than an ISO 15552 profile cylinder, so it slots into presses and clamping fixtures where a full-length body simply will not fit.
The S45C hard-chrome plated 20 mm rod runs on a two-way grease-retaining seal with a fixed TPU bumper at each end, and the male rod thread (B code) bolts straight into standard tooling. Speed range is 30-500 mm/s across 0.15-1.0 MPa (22-145 psi) of clean, 40 um filtered air.

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 ACEJ80X35-30B Is Used
Fixture clamping on a CNC line
The compact body, roughly half the mounting length of an ISO 15552 profile cylinder, clamps castings inside a tight machining enclosure where every millimetre of envelope counts.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X35-30B the Right Cylinder?
Remember the stop screw only shortens the extend stroke and is not a mid-stroke lock - on air loss the piston still drifts, so add a separate holding valve if the load must stay put. FA flange and LB foot mountings plus I/Y rod knuckles attach to the ISO 21287 face, and if you need position feedback, order the -S variant so CMSE / DMSE switches can be fitted; this non-S model carries no magnet.
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 ACEJ80X35-30B 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 is a 30 mm adjustment window: an external stop screw shortens the 35 mm extend stroke on site, so the usable range is 5-35 mm. It shortens only - it cannot extend past 35 mm, and it is a mechanical end stop, not a load-holding brake.
It is an ISO 21287 compact cylinder: hard-anodized aluminium body with a roller-burnished bore, S45C hard-chrome plated 20 mm rod, threaded aluminium covers and a fixed TPU bumper at each end. Air supply is 0.15-1.0 MPa (22-145 psi), filtered to 40 um, running 30-500 mm/s between -20 and +70 C. This version has no magnet; order the -S code to enable CMSE / DMSE switches. FA flange, LB foot and I/Y knuckles bolt to the standard face, and the port is 1/8" PT with a male rod thread.
