About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X55-50S
The ACEJ100X55-50S is a double acting ISO 21287 compact cylinder with an adjustable extend stroke. Its 100 mm bore delivers 3927 N push and 3769.9 N pull at 0.5 MPa, rising to 5497.8 N at 0.7 MPa, so it handles heavy clamping and press-fit work in a body that saves about 50% of the mounting length of an ISO 15552 profile cylinder. The external stop screw trims the 55 mm stroke anywhere within the ordered 50 mm window, giving a usable extend range of 5-55 mm without swapping the cylinder.
In practice, plan for roughly 2356 N of real work at 0.5 MPa, which corresponds to lifting about 200 kg vertically with a 2:1 margin. The hard-anodized aluminium body carries a 20 mm S45C hard-chrome rod, a fixed TPU bumper at each end absorbs end-of-stroke energy, and because this model carries the optional -S magnet, CMSE / DMSE reed or solid-state switches can be mounted directly in the body slots. Air supply is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and the 1/8" port matches the 100 mm bore.

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 | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3770 N |
| 0.7 MPa | 5498 N | 5278 N |
| Max (@1.0 MPa) | 801 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X55-50S Is Used
Heavy fixture clamping
Clamps large machined castings on a CNC fixture with about 2356 N of usable force, and the stop screw dials the clamp travel down from 55 mm to as little as 5 mm per part.
Short-stroke press station
Delivers 3927 N push at 0.5 MPa for staking or press-fitting bushings into housings, with the 5-55 mm adjustable range matching shallow press work.
Pallet lift-and-lower module
Raises roughly 200 kg pallets or die carts vertically with a 2:1 margin, while the fitted -S magnet feeds CMSE switches for down-position confirmation.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X55-50S the Right Cylinder?
Size by force: a 63 mm bore gives 1558.6 N push at 0.5 MPa, while the next step up, the 125 mm bore, reaches 6135.9 N. If your load needs more than about 2356 N of usable force, the 100 mm bore is the right class. Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock, so on air loss the piston still drifts. FA flange, LB foot and FTC brackets plus I/Y rod knuckles bolt straight to the ISO 21287 face, and the fitted -S magnet lets you add CMSE / DMSE switches for end-position 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 ACEJ100X55-50S FAQ
At 0.5 MPa it pushes 3927 N and pulls 3769.9 N; at 0.7 MPa it pushes 5497.8 N and pulls 5277.9 N, with a theoretical maximum of 800.9 kgf at 1.0 MPa. The -50 code is a 50 mm adjustment window: an external stop screw shortens the 55 mm extend stroke by up to 50 mm, so the usable extend range is 5-55 mm. It shortens the stroke only and acts as a mechanical end stop, not a load-holding brake. Operating pressure is 0.15-1.0 MPa (22-145 psi) and speed is 30-500 mm/s.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits tight guards and gantries. It has a hard-anodized aluminium body, a 20 mm hard-chrome-plated S45C rod, a fixed TPU bumper at both ends, and a 1/8" port. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be clipped into the body slots; FA flange, LB foot and FTC brackets plus I/Y knuckles bolt straight to the standard face.
