About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X55-30SB
A double acting ISO 21287 compact cylinder, the ACEJ80X55-30SB pairs an 80 mm bore with a 55 mm stroke that an external stop screw trims on site: the -30 window lets you set the extend stroke anywhere from 25 to 55 mm without swapping the unit. 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 rod thread (B code) bolts straight into male-threaded tooling.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into presses, clamping fixtures and gantries where a full-length body will not reach. Because the -S magnet is fitted on this model, CMSE or DMSE reed and solid-state switches can be clipped onto the body for end-of-stroke signalling.

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 ACEJ80X55-30SB Is Used
Clamping on machining fixtures
The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it clamps workpieces inside tight CNC jigs where a full-length body would foul the toolpath.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ80X55-30SB the Right Cylinder?
If your jig needs 2000-2500 N of clamp or press force at 0.5 MPa, this 80 mm bore sits right in the sweet spot with headroom. The stop screw is a mechanical end stop for the extend stroke only, so on air loss the piston can still drift - do not rely on it to hold a load mid-stroke. FA flange or LB foot mounts plus I and Y rod knuckles bolt to the ISO 21287 face, and the fitted -S magnet means CMSE / DMSE switches are ready when you are. Runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, -20 to +70 C.
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 ACEJ80X55-30SB 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. The -30 code is a 30 mm adjustment window: an external stop screw shortens the 55 mm extend stroke by up to 30 mm, giving a usable range of 25-55 mm. It cannot lengthen the stroke past 55 mm, and the stop is an end stop only - it never locks or brakes a load.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body, S45C hard-chrome-plated 20 mm rod and a fixed TPU bumper at both ends that decelerates the piston at end of stroke. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder. This model carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be mounted in the body slots for position feedback. Ports are 1/8" (PT), and FA flange or LB foot mounts plus I/Y rod knuckles bolt straight to the standard face.
