About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X100-40S
The ACEJ100X100-40S is a double acting, adjustable-stroke compact cylinder built to ISO 21287: a 100 mm bore pushing 3927 N (pull 3769.9 N) at 0.5 MPa, and 5497.8 N at 0.7 MPa. The -40 code adds an external stop screw that trims the extend stroke anywhere in a 40 mm window, giving a usable 60-100 mm range without changing hardware. Its short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so heavy presses and clamps fit into tight machine frames.
This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be slid into the body slots for end-of-stroke signalling. The hard-anodized aluminium body pairs with a 20 mm S45C hard-chrome rod and a female M12x1.75 thread; a fixed TPU bumper at each end absorbs end-of-stroke impact. At 0.5 MPa the push force equates to roughly 400 kgf, so for real work plan on about 2356 N - enough to lift around 200 kg vertically with a 2:1 margin.

Where the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X100-40S Is Used
Bale compaction station
A recycling line compacts loose cardboard into a 500 mm chute; the 100 mm bore delivers 3927 N at 0.5 MPa and the stop screw trims the stroke to the exact bale height within the 40 mm window.
Press-fit bearing assembly
An automotive cell presses bearings into housings needing about 2300 N of working force; the 60-100 mm adjustable range lets one cylinder serve two housing depths, with CMSE switches confirming seat.
Pallet stopper gate
A warehouse conveyor raises a heavy stop gate of roughly 180 kg; the cylinder lifts about 200 kg vertically at 0.5 MPa with a 2:1 margin, and the LB foot mount anchors it under the line frame.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X100-40S the Right Cylinder?
At 100 mm bore this is the top of the mid-range: 3927 N push at 0.5 MPa. Step down to the 63 mm bore (1558.6 N) for lighter clamping, or up to the 125 mm bore (6135.9 N) when the load needs more margin. Remember the stop screw is a mechanical end stop only - on air loss the piston drifts, so add a valve or lock for load holding. FA flange and LB foot mountings bolt to the ISO 21287 face, and the fitted -S magnet lets CMSE / DMSE switches report position. Ports are 1/8" PT; speed range 30-500 mm/s.
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 ACEJ100X100-40S FAQ
At 0.5 MPa it pushes 3927 N and pulls 3769.9 N; at 0.7 MPa push rises to 5497.8 N (pull 5277.9 N), with a theoretical maximum of 800.9 kgf at 1.0 MPa. The -40 code sets a 40 mm adjustment window: an external stop screw shortens the 100 mm extend stroke, so the working range is 60-100 mm. It shortens the stroke only - it never extends past the ordered stroke, and it is not a mid-stroke lock, so the piston still drifts if air is lost. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters in guarded or gantry-mounted machinery. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be clipped into the body slots for position feedback; without -S there is no magnet. FA flange and LB foot brackets bolt straight to the ISO 21287 face, the rod end is female M12x1.75, the port is 1/8" PT, and fixed TPU bumpers at both ends absorb end-of-stroke impact.
