About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X175-20S
A double acting ISO 21287 compact cylinder, the ACEJ80X175-20S pairs an 80 mm bore with a 175 mm stroke that an external stop screw trims by up to 20 mm on site, giving a usable extend range of 155-175 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 ceiling of 512.6 kgf at 1.0 MPa. The hard-anodized aluminium body carries magnet slots along its full length, and the -S code on this model means the magnet is fitted, so CMSE or DMSE reed and solid-state switches mount directly without drilling.
The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into press fixtures and gantries where a full-length body will not fit. A fixed TPU bumper at each end absorbs end-of-stroke shock, the S45C hard-chrome rod resists wear, and FA flange, LB foot or FTC brackets bolt straight to the ISO 21287 face.

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 ACEJ80X175-20S Is Used
Palletizing lift-assist
With about 153 kg of vertical lift equivalent at 0.5 MPa, the 80 mm bore raises cartons or trays on warehouse gantries where the short body keeps the frame low.
Packaging line stopper
Stopping moving totes on a bottling conveyor needs repeatable force; the fixed TPU bumper softens each engagement and the fitted magnet feeds a CMSE switch for cycle counting.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X175-20S the Right Cylinder?
Size against neighbours: a 63 mm bore pushes 1558.6 N at 0.5 MPa, while a 100 mm bore reaches 3927.0 N - this 80 mm sits between them at 2513.3 N, ideal for mid-heavy clamping and pressing. Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock: on air loss the piston still drifts, so add a separate holding valve where a load must stay put. Mount with FA flange or LB foot, add I or Y rod knuckles for side misalignment, and note the magnet is already fitted on this -S model for CMSE / DMSE switch positioning. Female M12x1.75 rod thread, 1/8" ports, PT.
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 ACEJ80X175-20S FAQ
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 maximum of 512.6 kgf at 1.0 MPa. The -20 code sets a 20 mm adjustment window: an external stop screw shortens the 175 mm extend stroke by up to 20 mm, so the working range is 155-175 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.
It is an ISO 21287 compact cylinder whose short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits tight guards and jigs. FA flange, LB foot and FTC brackets, plus I and Y rod knuckles, mount on the standard ISO 21287 face. The magnet is the optional -S code and this model carries it, so CMSE / DMSE switches can be slid into the body slots for end-of-stroke signalling. The TPU bumper at both ends is a fixed pad that softens end-of-stroke impact only - it never brakes or holds a load.
