About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X50-50S
A double acting ISO 21287 compact cylinder, the ACEJ80X50-50S pairs an 80 mm bore with a 50 mm stroke that an external stop screw trims anywhere in the 0-50 mm window, so one unit serves several fixture positions. At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa those figures 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 and S45C hard-chrome plated 20 mm rod stand up to daily clamping cycles.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters when a 50 mm stroke must fit inside a welding fixture or press gantry. The fitted -S magnet lets CMSE / DMSE switches report end positions, and the 1/8" port feeds the 30-500 mm/s speed range.

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 ACEJ80X50-50S Is Used
Small press and forming station
With about 3518.6 N at 0.7 MPa, the 80 mm bore drives light staking, embossing and snap-fit pressing on electronics assembly lines where a full-length profile cylinder will not fit.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X50-50S the Right Cylinder?
Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock, so the rod will still drift if air is lost. FA flange or LB foot mounting bolts to the ISO 21287 face, and I or Y rod knuckles suit swinging clamp arms; the -S magnet is already fitted on this model for CMSE / DMSE switch mounting.
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 ACEJ80X50-50S FAQ
The -50 code is a 50 mm adjustment window: an external stop screw shortens the 50 mm extend stroke on site, giving a usable range of 0-50 mm. It is a mechanical end stop only and does not hold a load if air pressure is lost. Operating pressure is 0.15-1.0 MPa (22-145 psi) and speed is 30-500 mm/s.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and gantries. A fixed TPU bumper at each end absorbs end-of-stroke impact. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be clipped into the body slots to signal positions. FA flange and LB foot mounts plus I and Y rod knuckles bolt straight to the ISO 21287 face; the rod end thread is female M12x1.75 and the air port is 1/8".
