Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X275-50B
The AirTAC ACEJ80~100 Adjustable Compact Cylinder ACEJ80X275-50B is a genuine double acting, double rod, adjustable stroke ISO 21287 compact air cylinder with a Ø80mm bore and 275mm stroke, 1/8" air ports and a hard-anodized aluminium body. Its short compact envelope saves about 50% of the mounting length of an ISO 15552 profile cylinder.

About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X275-50B
The ACEJ80X275-50B is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 275 mm stroke by up to 50 mm on site, giving a usable range of 225-275 mm. The B code gives a male rod thread on the 20 mm rod, and the port is 1/8" PT.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so this heavy-thrust cylinder still fits deep press fixtures and long-stroke gantries where space is tight. A fixed TPU bumper at each end absorbs end-of-stroke energy, and FA flange or LB foot mounts 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 ACEJ80X275-50B Is Used
Pallet stop and eject on conveyor lines
A 275 mm extend stroke kicks a tote off a roller conveyor, and the compact body tucks under guarding that an ISO 15552 profile cylinder of the same stroke cannot fit.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X275-50B the Right Cylinder?
If your load needs more than about 1508 N of sustained work force, step up to the 100 mm bore. The stop screw only shortens the extend stroke and is not a mid-stroke lock - on air loss the piston still drifts, so add a valve or external stop if you must hold position. Order the -S code if you want the optional magnet for CMSE / DMSE switches; this model has no magnet fitted.
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 ACEJ80X275-50B FAQ
At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa it pushes 3518.6 N and pulls 3298.7 N, with a theoretical maximum of 512.6 kgf at 1.0 MPa. The -50 code sets a 50 mm adjustment window: the external stop screw shortens the 275 mm extend stroke anywhere in that window, so the working range is 225-275 mm. It runs double acting on air at 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s.
The ISO 21287 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. FA flange and LB foot mounts bolt to the standard ISO 21287 face. This model has no magnet; order the -S version to enable CMSE / DMSE reed or solid-state switches on the body's magnet slots.
