Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X55-30SB
The AirTAC ACEJ80~100 Adjustable Compact Cylinder ACEJ100X55-30SB is a genuine double acting, double rod, adjustable stroke ISO 21287 compact air cylinder with a Ø100mm bore and 55mm 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 ACEJ100X55-30SB
A double acting ISO 21287 compact cylinder with a tunable extend stroke, the ACEJ100X55-30SB pairs a 100 mm bore with a 55 mm stroke and a 30 mm adjustment window. An external stop screw trims the extend stroke on site anywhere from 25 to 55 mm, so one cylinder serves several die positions without re-plumbing. At 0.5 MPa it pushes 3927 N and pulls 3769.9 N; at 0.7 MPa push rises to 5497.8 N. The hard-anodized aluminium body with an S45C hard-chrome plated 20 mm rod runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters when a 300 kg-class press head must fit inside a guarded weld cell. The -S magnet this model carries lets CMSE / DMSE switches report end positions, and the fixed TPU bumpers at both ends absorb end-of-stroke shock.

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 (Ø100mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 3770 N |
| 0.7 MPa | 5278 N |
| Max (@1.0 MPa) | 769 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 ACEJ100X55-30SB Is Used
Weld fixture clamping
Clamps steel brackets against weld tables inside tight guarding, where the short ISO 21287 body saves about 50% of the length of an ISO 15552 profile cylinder.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X55-30SB 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 for suspended loads. FA flange or LB foot mountings bolt to the ISO 21287 face, and the male rod thread (B code) suits interchangeable tooling plates; the fitted -S magnet works with CMSE / DMSE switches.
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 ACEJ100X55-30SB FAQ
At 0.5 MPa it pushes 3927 N and pulls 3769.9 N; at 0.7 MPa push is 5497.8 N and pull 5277.9 N; theoretical maximum is 800.9 kgf at 1.0 MPa. The 30 mm stop screw trims the 55 mm extend stroke down to 25 mm on site. Operating range is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, port 1/8" PT, male rod thread on a 20 mm rod.
This version carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be clipped into the body slots to signal both end positions. FA flange, LB foot and FTC brackets plus I/Y rod knuckles bolt straight to the ISO 21287 face. The fixed TPU bumpers at each end absorb end-of-stroke energy but never hold or brake a load.
