About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X275-30B
The ACEJ100X275-30B is a double acting ISO 21287 compact cylinder with a 100 mm bore and a 275 mm stroke that an external stop screw trims by up to 30 mm, giving a usable extend range of 245-275 mm. At 0.5 MPa it pushes 3927 N and pulls 3769.9 N; at 0.7 MPa push rises to 5497.8 N. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so heavy presses and gantries stay compact.
The hard-anodized aluminium body carries a S45C hard-chrome plated 20 mm rod, a fixed TPU bumper at each end, and a 1/8" port. The optional -S magnet enables CMSE / DMSE switches; this unit ships without it. Male rod thread (B code), PT port thread, speed 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 (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 ACEJ100X275-30B Is Used
Pallet clamp and lift-assist arms
With about 240 kg of vertical lift equivalent at 0.5 MPa, the 100 mm bore handles pallet clamping and lift-assist tooling in warehouses where the short ISO 21287 body must fit inside tight guard frames.
Gate and heavy-slide actuation
Drives heavy machine gates and sliding dies in steel and plastics plants; the male rod thread (B code) accepts rod eyes or custom tooling, and LB foot mounting suits long-run slide frames.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X275-30B the Right Cylinder?
The 275 mm stroke is within the 300 mm max standard stroke for bore 100. Remember the stop screw only shortens the extend stroke and is not a mid-stroke lock: on air loss the piston still drifts, so add a separate holding valve if the load must stay put. FA flange or LB foot mountings bolt to the ISO 21287 face, and ordering the -S code adds the magnet for CMSE / DMSE switch sensing.
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 ACEJ100X275-30B FAQ
Push is 3927 N and pull 3769.9 N at 0.5 MPa; at 0.7 MPa push reaches 5497.8 N and pull 5277.9 N, with a theoretical maximum of 800.9 kgf at 1.0 MPa. It is double acting with a 275 mm stroke adjustable down to 245 mm via the stop screw, runs on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um, proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C, speed 30-500 mm/s, 1/8" port, 20 mm male-threaded rod.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body, threaded aluminium covers, a hard-chrome plated S45C rod and fixed TPU bumpers at both ends that only decelerate at stroke ends. Mounting brackets such as FA flange or LB foot bolt to the standard ISO 21287 face. Sensing requires the optional -S magnet ordered with the cylinder; with the -S code, CMSE / DMSE switches track position along the body slots. This model (no S code) has no magnet fitted.
