About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X125-30B
A double acting ISO 21287 compact cylinder, the ACEJ80X125-30B pairs an 80 mm bore with a 125 mm stroke that an external stop screw can trim anywhere in a 30 mm window, giving a usable extend range of 95-125 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 to your tooling.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into presses and gantries where a full-length body will not fit. A fixed TPU bumper at each end absorbs end-of-stroke energy, and the hard-anodized aluminium body with an S45C hard-chrome plated rod stands up to high-cycle duty. Note that this unit carries no magnet; order the optional -S code if you later need CMSE / DMSE switch position feedback.

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 ACEJ80X125-30B Is Used
Gantry pick-and-place lift
The compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder, freeing headroom inside a gantry frame, and the male rod thread accepts a gripper or vacuum plate directly.
Clamp fixture on a machining centre
LB foot mounting and a 95-125 mm adjustable extend range let a fixture builder dial in clamp position for cast housings without shimming, with the 1/8" port feeding high flow for fast 30-500 mm/s cycling.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X125-30B the Right Cylinder?
The 125 mm stroke is well inside the 300 mm maximum standard stroke for bore 80, so no made-to-order build is required. Remember the stop screw is a mechanical end stop, not a mid-stroke lock: on air loss the piston still drifts, so add a separate holding valve for suspended loads. FA flange or LB foot mountings and I/Y rod knuckles suit the male thread; PT ports are standard, with G available. If position sensing matters, specify the -S magnet variant.
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 ACEJ80X125-30B FAQ
At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa push rises to 3518.6 N and pull to 3298.7 N, with a theoretical maximum of 512.6 kgf at 1.0 MPa. The -30 code sets a 30 mm adjustment window: an external stop screw shortens the 125 mm extend stroke by up to 30 mm, so the working range is 95-125 mm. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body, an S45C hard-chrome plated 20 mm rod and threaded aluminium covers, about 50% shorter in mounting length than an ISO 15552 profile cylinder. A fixed TPU bumper at each end absorbs end-of-stroke energy but never locks or holds a load. Mounting options include FA flange and LB foot plus I/Y rod knuckles on the male thread. This model has no magnet; order the optional -S version to enable CMSE / DMSE reed or solid-state switches.
