About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X45-30B
A double acting ISO 21287 compact cylinder, the ACEJ80X45-30B pairs an 80 mm bore with a 45 mm stroke that an external stop screw trims on site by up to 30 mm, giving a usable extend range of 15-45 mm. At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N, rising to 3518.6 N at 0.7 MPa, with a theoretical peak of 512.6 kgf at 1.0 MPa. The male (B code) rod thread on the 20 mm rod bolts straight to standard tooling plates.
The hard-anodized aluminium body with an S45C hard-chrome-plated rod saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight press fixtures and guarded cells. Fixed TPU bumpers absorb end-of-stroke energy, speed spans 30-500 mm/s, and pressure runs 0.15-1.0 MPa (22-145 psi).

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 ACEJ80X45-30B Is Used
Weld fixture clamping
Clamps sheet-metal panels in automotive weld cells where the short ISO 21287 body fits inside tight fixture framing that a full-length cylinder cannot.
Pallet stop-and-lower station
Lowers loaded pallet sections of about 120 kg on conveyor lines, with the male rod thread coupling directly to lift plates.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X45-30B the Right Cylinder?
Size it against neighbours: the 63 mm bore pushes 1558.6 N at 0.5 MPa, while the 100 mm bore reaches 3927.0 N, so this 80 mm model sits in the 2500 N class for heavy clamping and short-lift work. Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock, so the piston still drifts if air is lost. FA flange, LB foot and FTC brackets plus I/Y rod knuckles mount on the ISO 21287 face; this unit has no magnet, so order the -S code if CMSE / DMSE switches are planned later.
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 ACEJ80X45-30B 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: an external stop screw shortens the 45 mm extend stroke by up to 30 mm, so the working range is 15-45 mm. It runs double acting 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.
The hard-anodized aluminium body is an ISO 21287 compact design that saves about 50% of the mounting length of an ISO 15552 profile cylinder, with fixed TPU bumpers at both ends. FA flange, LB foot and FTC brackets plus I/Y rod knuckles bolt to the standard face. Sensors need the optional -S magnet code, which enables CMSE / DMSE switches; this model without -S carries no magnet, so no switch can be read on it.
