About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X70-50S
A double acting ISO 21287 compact cylinder, the ACEJ80X70-50S pairs an 80 mm bore with a 70 mm stroke that an external stop screw trims anywhere in a 50 mm window, giving a usable extend range of 20-70 mm. At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N, rising to 3518.6 N at 0.7 MPa, so it handles heavy clamping and press-fit work in a body far shorter than a conventional frame. Air supply is 0.15-1.0 MPa (22-145 psi), speed runs 30-500 mm/s, and fixed TPU bumpers absorb end-of-stroke shock at both ends.
The hard-anodized aluminium body with an S45C hard-chrome plated 20 mm rod keeps wear low in daily production duty. Because the short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, it slots into weld fixtures and press gantries where a full-length body will not reach.

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 ACEJ80X70-50S Is Used
Bench press and staking
With 3518.6 N available at 0.7 MPa, this bore stakes bushings and presses bearings in small assembly presses where the short body fits under a fixed gantry.
Position-monitored ejection
The fitted -S magnet with CMSE / DMSE switches confirms extend and retract on packaging line ejectors, while the 70 mm stroke clears deep trays.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X70-50S the Right Cylinder?
The stop screw is a mechanical end stop for the extend stroke only, not a mid-stroke lock, so on air loss the piston still drifts and a separate holding valve is needed for suspended loads. FA flange, LB foot and FTC brackets plus I/Y rod knuckles bolt straight to the ISO 21287 face, and the fitted -S magnet lets CMSE / DMSE switches report position without any retrofit.
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 ACEJ80X70-50S 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 -50 code is a 50 mm adjustment window: an external stop screw shortens the 70 mm extend stroke by up to 50 mm, so the working range is 20-70 mm. It runs double acting on air at 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s, with a 1/8" port and a female M12x1.75 rod thread.
It is an ISO 21287 compact cylinder whose short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, S45C hard-chrome rod and fixed TPU bumpers at both ends. The -S magnet this model carries accepts CMSE / DMSE reed or solid-state switches for position feedback. FA flange, LB foot and FTC brackets plus I and Y rod knuckles mount directly on the ISO 21287 face, so it drops into standard fixtures.
