About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X35-20SB
A double acting ISO 21287 compact cylinder, the ACEJ80X35-20SB pairs an 80 mm bore with a 35 mm stroke and a 20 mm adjustment window: an external stop screw trims the extend stroke on site anywhere between 15 and 35 mm. At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N, rising to 3518.6 N at 0.7 MPa, with a theoretical ceiling of 512.6 kgf at 1.0 MPa. The male (B code) rod thread and 1/8" PT ports suit heavier tooling plates.
The hard-anodized aluminium body with an S45C hard-chrome plated rod runs at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s and -20 to +70 C, with a fixed TPU bumper at both ends. Because the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, it slots into presses and clamping fixtures where a full-length body will not fit. The fitted -S magnet accepts CMSE / DMSE switches for end-of-stroke sensing.

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 ACEJ80X35-20SB Is Used
Fixture clamping on a machining line
Clamps cast-iron pump housings against a jig; the short ISO 21287 body fits inside the guard envelope where an ISO 15552 profile cylinder would not.
Gated pallet transfer
A stop gate on a conveyor drops and rises 15-35 mm per cycle; the fitted -S magnet with CMSE switches confirms gate-down before the next pallet is released.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X35-20SB the Right Cylinder?
Size the -20 window only if your fixture genuinely needs on-site stroke trimming between 15 and 35 mm; for a fixed stroke, the plain ACE in the same bore is simpler. The stop screw is a mechanical end stop, not a mid-stroke lock, so the rod still drifts if air is lost. FA flange or LB foot mounts plus I/Y rod knuckles bolt to the ISO 21287 face, and the fitted -S magnet lets CMSE / DMSE switches report position.
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 ACEJ80X35-20SB 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 ordered stroke is 35 mm and the -20 code gives a 20 mm adjustment window, so the extend stroke can be trimmed on site anywhere from 15 to 35 mm. It is double acting, runs at 30-500 mm/s and 0.15-1.0 MPa (22-145 psi), and the stop screw is an end stop only, not a load-holding lock.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body, S45C hard-chrome plated 20 mm rod and fixed TPU bumpers at both ends, about 50% shorter in mounting length than an ISO 15552 profile cylinder. FA flange or LB foot mounts and I/Y rod knuckles bolt to the standard face, and 1/8" PT ports feed the air. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be clamped into the body slots for end-of-stroke signalling.
