About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X275-20B
The ACEJ80X275-20B is a double acting, adjustable-stroke compact cylinder built to ISO 21287. Its 80 mm bore delivers 2513.3 N in push and 2356.2 N in pull at 0.5 MPa, rising to 3518.6 N at 0.7 MPa, with a theoretical peak of 512.6 kgf at 1.0 MPa. The hard-anodized aluminium body carries a 20 mm S45C hard-chrome rod, and the male rod thread (B code) bolts straight into standard tooling. Air supply runs 0.15-1.0 MPa (22-145 psi) with speeds of 30-500 mm/s.
The -20 code gives a 20 mm adjustment window: an external stop screw trims the extend stroke anywhere between 255 and 275 mm on site, so one cylinder serves several fixture depths. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters inside presses and guarding. Note the stop screw is an end stop only - on air loss the rod still drifts.

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 ACEJ80X275-20B Is Used
Pallet gate actuation
Swings or lifts heavy conveyor gate sections in packaging lines; the 275 mm stroke clears a 250 mm gate leaf and the male rod thread suits knuckle links.
Machine clamp drop
Drops a locating clamp into position inside tight guarding, where the short ISO 21287 body fits space a full-length profile cylinder cannot.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X275-20B 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 - pick the 80 mm when your load sits between roughly 900 and 1500 N of real work. If the job needs position feedback, order the -S variant instead, since this model has no magnet and no CMSE / DMSE switch can be fitted. FA flange or LB foot mounts plus I and Y rod knuckles suit the ISO 21287 face; the male rod thread suits clevis-style tooling. Remember the adjuster trims the extend stroke only and never holds a load.
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 ACEJ80X275-20B 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 80 mm bore uses a 1/8" PT port and a 20 mm rod with male thread. Operating range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C, speed 30-500 mm/s, air filtered to 40 um. The extend stroke is adjustable from 255 to 275 mm via the stop screw.
An external stop screw shortens the extend stroke by up to 20 mm within the ordered -20 window, so the working range is 255-275 mm; it cannot lengthen the stroke past 275 mm. Fixed TPU bumpers at both ends absorb end-of-stroke energy. This unit has no magnet, so CMSE / DMSE switches cannot be mounted - order the -S code for the optional magnet if sensing is needed. FA flange and LB foot mounts bolt to the ISO 21287 face.
