Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X100-20SB
The AirTAC ACEJ80~100 Adjustable Compact Cylinder ACEJ80X100-20SB is a genuine double acting, double rod, adjustable stroke ISO 21287 compact air cylinder with a Ø80mm bore and 100mm stroke, 1/8" air ports and a hard-anodized aluminium body.

About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X100-20SB
This is a double acting AirTAC ACEJ with an adjustable extend stroke: an external stop screw trims the 100 mm stroke by up to 20 mm on site, giving a usable range of 80-100 mm without changing the cylinder. At the 80 mm bore it pushes 2513.3 N and pulls 2356.2 N at 0.5 MPa, rising to 3518.6 N at 0.7 MPa, with a theoretical ceiling of 512.6 kgf at 1.0 MPa. The -S magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clamped straight into the body slots for end-of-stroke signalling.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why this bore class fits clamping gantries and press fixtures that a full-length body cannot enter. A fixed TPU bumper at each end absorbs end-of-stroke shock, the hard-anodized aluminium body runs on a 20 mm hard-chrome S45C rod, and the 1/8" ports take air filtered to 40 um at 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 (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 ACEJ80X100-20SB Is Used
Pallet gate actuator
Swinging heavy pallet-line gates needs the 2.5 kN class plus a short body; the ISO 21287 frame fits inside the guard where a profile cylinder would foul the frame.
Tracked clamp with position feedback
With the fitted magnet, CMSE or DMSE switches confirm clamp-seated and released states on a machining-centre fixture running 30-500 mm/s clamp cycles.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X100-20SB the Right Cylinder?
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. The male rod thread (B code) suits rod knuckles, and FA flange or LB foot mounts bolt to the ISO 21287 face; PT ports are standard, with G available to order.
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 ACEJ80X100-20SB FAQ
At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa those figures 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 100 mm extend stroke to as little as 80 mm. The stop is a mechanical end stop only - it never holds a load if air is lost. Operating range is 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s.
It is an ISO 21287 compact cylinder whose short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, 20 mm hard-chrome rod and fixed TPU bumpers at both ends. This -S version carries the magnet, so CMSE or DMSE switches mount in the body slots; models ordered without -S have no magnet. FA flange and LB foot mounts plus I and Y rod knuckles bolt to the standard face, and the male rod thread suits adjustable knuckles.
