About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X275-50B
The ACEJ100X275-50B is a double acting ISO 21287 compact cylinder with a 100 mm bore and a 275 mm stroke that an external stop screw can trim by up to 50 mm on site, giving a usable extend range of 225-275 mm. At 0.5 MPa it pushes with 3927 N and pulls with 3769.9 N; at 0.7 MPa those figures rise to 5497.8 N and 5277.9 N. The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so heavy-duty pressing and clamping still fit inside tight machine frames.
The hard-anodized aluminium body carries an S45C hard-chrome-plated 20 mm rod, a fixed TPU bumper at each end absorbs end-of-stroke shock, and the B code gives a male rod thread with a 1/8" PT port. Speed range is 30-500 mm/s over 0.15-1.0 MPa (22-145 psi).

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 (Ø100mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 3770 N |
| 0.7 MPa | 5278 N |
| Max (@1.0 MPa) | 769 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 ACEJ100X275-50B Is Used
Gate drive on a foundry conveyor
The 275 mm stroke swings heavy slide gates between a mold pour station and a cooling conveyor, and the short ISO 21287 body fits where a full-length profile cylinder cannot.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X275-50B the Right Cylinder?
If your load needs less than about 2400 N of working force, step down to the 80 mm bore and save air consumption. Remember the stop screw only shortens the extend stroke and is not a mid-stroke lock, so on air loss the piston still drifts; use a separate valve or lock for holding. Mount with FA flange or LB foot on the ISO 21287 face, and if you need position feedback, order the -S variant so CMSE / DMSE switches can be fitted; this model has no magnet.
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 ACEJ100X275-50B FAQ
Push is 3927 N and pull is 3769.9 N at 0.5 MPa; at 0.7 MPa push reaches 5497.8 N and pull 5277.9 N, with a theoretical maximum of 800.9 kgf at 1.0 MPa. It is double acting with a 275 mm stroke adjustable down to 225 mm via the 50 mm stop-screw window, runs at 30-500 mm/s on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um, has a 1/8" PT port, a 20 mm male-thread rod, and a fixed TPU bumper at both ends. Proof pressure is 1.5 MPa (215 psi) and operating temperature is -20 to +70 C.
It is an ISO 21287 compact cylinder whose hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with threaded aluminium covers and grease-retaining piston seals. FA flange and LB foot mountings bolt to the standard face. Position sensing requires the optional -S magnet code, which allows CMSE / DMSE reed or solid-state switches; this model, ordered without -S, carries no magnet, so no switch can be mounted on it.
