About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X300-20
A heavy-duty double acting ISO 21287 compact cylinder, the ACEJ100X300-20 pairs a 100 mm bore with a 300 mm stroke that an external stop screw can trim by up to 20 mm, giving a usable extend range of 280-300 mm. At 0.5 MPa it pushes 3927 N and pulls 3769.9 N, and the hard-anodized aluminium body with an S45C hard-chrome plated 20 mm rod stands up to continuous press and clamp duty.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so a 300 mm stroke fits machines where a full-length body would not. For sizing: the push force of 3927 N equates to roughly 400 kg of vertical lift, so with a 2:1 margin plan on lifting about 200 kg vertically. Note this model ships without the optional -S magnet, so CMSE / DMSE switches cannot be read on it as configured.

Where the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X300-20 Is Used
Hydraulic press assist
The 3927 N push at 0.5 MPa pre-presses bearings or bushings into housings before a final hydraulic press cycle, with the 20 mm window letting you trim the 300 mm stroke to the fixture.
Pallet gate lifting
With about 200 kg of vertical lift capacity at a 2:1 margin, the cylinder raises heavy pallet-stop gates and guard doors on packaging lines within a compact envelope.
Aluminium ingot clamping
LB foot mounting and the 280-300 mm adjustable extend range suit long-stroke clamps that hold ingots or extrusions during sawing and machining.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X300-20 the Right Cylinder?
At this bore size the 3927 N push at 0.5 MPa covers heavy clamping, press-fitting and lifting; if your load needs under about 1558 N at 0.5 MPa, the 63 mm bore (1558.6 N push) saves air and space, while the 125 mm bore (6135.9 N push) is the step up. The stop screw is a mechanical end stop for the extend stroke only - it does not lock the piston mid-stroke, and on air loss the rod will drift, so add a separate holding valve if the load must stay put. FA flange or LB foot mounting bolts to the ISO 21287 face; order the -S code if you need the magnet for CMSE / DMSE switches. Female M12x1.75 rod thread, 1/8" ports, PT.
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 ACEJ100X300-20 FAQ
At 0.5 MPa it pushes 3927 N and pulls 3769.9 N; at 0.7 MPa push rises to 5497.8 N and pull to 5277.9 N, with a theoretical maximum of 800.9 kgf at 1.0 MPa. It is double acting with an adjustable extend stroke (20 mm window, usable 280-300 mm), runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C, speed 30-500 mm/s, with 1/8" ports and a female M12x1.75 rod thread.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so a 300 mm stroke fits tight gantries and guards. Fixed TPU bumpers at both ends absorb end-of-stroke energy but do not hold or brake a load. FA flange and LB foot brackets bolt to the standard ISO 21287 face. This version has no magnet; order the -S code to enable CMSE / DMSE switch position sensing.
