Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X30-20SB
The AirTAC ACEJ80~100 Adjustable Compact Cylinder ACEJ80X30-20SB is a genuine double acting, double rod, adjustable stroke ISO 21287 compact air cylinder with a Ø80mm bore and 30mm 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 ACEJ80X30-20SB
A double acting ISO 21287 compact cylinder, the ACEJ80X30-20SB pushes with 2513.3 N and pulls with 2356.2 N at 0.5 MPa, rising to 3518.6 N at 0.7 MPa. Its 80 mm bore drives a 20 mm hard-chrome S45C rod through a 30 mm stroke, and the -20 code means an external stop screw trims the extend stroke on site anywhere in a 10-30 mm window. The short hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight presses, guards and gantry fixtures. A fixed TPU bumper at each end absorbs end-of-stroke energy, and the male rod thread (B code) bolts straight to standard tooling.
The fitted -S magnet lets CMSE or DMSE reed or solid-state switches report end positions, while FA flange, LB foot and I/Y rod knuckle hardware mount directly to the ISO 21287 face. Air supply is 0.15-1.0 MPa (22-145 psi), filtered to 40 um, with speed from 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 ACEJ80X30-20SB Is Used
Gantry pick-and-place clamp
Clamping machined aluminium housings on a CNC loading gantry, the short body fits inside the Z-axis frame where a full-length profile cylinder cannot, and CMSE switches confirm grip.
Pallet-stacker gate latch
The about 128 kg vertical-lift equivalent secures heavy latch arms on warehouse equipment, with the male rod thread and LB foot mount tying into the existing chassis bracket.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X30-20SB the Right Cylinder?
Remember the stop screw is a mechanical end stop for the extend stroke only - on air loss the piston drifts, so add a separate valve or lock if the load must be held. With the -S magnet already fitted, add CMSE or DMSE switches for position feedback, and match FA flange or LB foot mounts to your fixture.
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 ACEJ80X30-20SB FAQ
Operating range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, air filtered to 40 um, -20 to +70 C, speed 30-500 mm/s, 1/8" ports, and a 20 mm adjustment window on the 30 mm stroke (usable 10-30 mm).
The ISO 21287 short-body build 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. This model carries the optional -S magnet, so CMSE or DMSE reed or solid-state switches can be clipped into the body slots to signal extend and retract positions.
