Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X40-10SB
The AirTAC ACEJ80~100 Adjustable Compact Cylinder ACEJ80X40-10SB is a genuine double acting, double rod, adjustable stroke ISO 21287 compact air cylinder with a Ø80mm bore and 40mm 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 ACEJ80X40-10SB
The ACEJ80X40-10SB is a double acting ISO 21287 compact cylinder with an adjustable extend stroke. At 0.5 MPa it pushes with 2513.3 N and pulls with 2356.2 N, rising to 3518.6 N on the extend stroke at 0.7 MPa. The -10 code gives a 10 mm stop-screw window, so the 40 mm stroke can be trimmed on site anywhere between 30 and 40 mm without changing the cylinder. This unit carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be mounted straight on the body, and the B code specifies a male rod thread.
The hard-anodized aluminium body with an S45C hard-chrome-plated rod saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which matters in tight clamping fixtures and guarded machines. Fixed TPU bumpers at both ends absorb end-of-stroke shock, and speed spans 30-500 mm/s.

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 ACEJ80X40-10SB Is Used
Pallet stopper on a heavy-duty conveyor
Mounted under a steel conveyor line, the short ISO 21287 body raises and lowers a stop blade for 200 kg pallets, with the -S magnet feeding a DMSE switch to confirm the up position.
Ejector on an injection mold fixture
A 40 mm extend stroke, trimmed to 35 mm via the stop screw, kicks finished housings off a mold nest; the male rod thread (B code) simplifies knuckle attachment to the ejector plate.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X40-10SB the Right Cylinder?
Remember the stop screw only shortens the extend stroke and is not a mid-stroke lock: on air loss the piston can still drift, so use a separate valve or lock for load holding. FA flange and LB foot mountings bolt to the ISO 21287 face, and PT ports are standard on this model.
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 ACEJ80X40-10SB FAQ
At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa push is 3518.6 N and pull 3298.7 N, with a theoretical maximum of 512.6 kgf at 1.0 MPa. Operating pressure is 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, and the port is 1/8" PT. The -10 window lets the stop screw trim the 40 mm extend stroke down to 30 mm.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body, S45C hard-chrome-plated 20 mm rod and threaded aluminium covers, about 50% shorter in mounting length than an ISO 15552 profile cylinder. Fixed TPU bumpers at both ends absorb end-of-stroke impact but never lock or hold a load. This model includes the optional -S magnet, so CMSE or DMSE reed and solid-state switches mount in the body slots; FA flange and LB foot brackets bolt directly to the standard face.
