About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X70-40S
The ACEJ100X70-40S 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 push at 0.7 MPa, with a theoretical peak of 800.9 kgf at 1.0 MPa. An external stop screw trims the 70 mm stroke by up to 40 mm, giving a usable extend range of 30-70 mm without changing the cylinder.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into heavy clamping fixtures and press heads where a full-length body will not fit. The hard-anodized aluminium body carries an S45C hard-chrome plated 20 mm rod, with a fixed TPU bumper at each end. Because this model carries the -S magnet code, CMSE or DMSE reed and solid-state switches can be mounted directly in the body slots. As a planning figure, treat roughly 2356 N (about 240 kg) as the practical working push at 0.5 MPa, which corresponds to lifting about 200 kg vertically with a 2:1 margin.

Where the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X70-40S Is Used
Pneumatic press head
The 3927 N push at 0.5 MPa suits short-stroke pressing of bushings and bearings, and the 30-70 mm adjustable window lets one cylinder serve several die heights.
Weld fixture clamping
Clamps automotive panel jigs with roughly 240 kg of practical working force at 0.5 MPa, while the compact body fits between fixture rails that exclude a full-profile cylinder.
Pallet gate actuator
Swings or lifts heavy conveyor gates on packaging lines; the -S magnet with a DMSE switch confirms gate-open and gate-closed positions for the PLC.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X70-40S the Right Cylinder?
At this bore size the step either way is large: a 63 mm ACEJ gives 1558.6 N push at 0.5 MPa, while the 125 mm bore jumps to 6135.9 N, so the 100 mm is the mid-heavy choice for loads in the 300-500 kgf class. Remember 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 valve or lock for load holding. FA flange or LB foot mounts bolt to the ISO 21287 face, and the fitted -S magnet lets CMSE / DMSE switches report end positions. Port is 1/8" PT; the female rod thread is M12x1.75.
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 ACEJ100X70-40S 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; the theoretical maximum is 800.9 kgf at 1.0 MPa. The -40 code is a 40 mm adjustment window: an external stop screw shortens the 70 mm extend stroke by up to 40 mm, so the usable range is 30-70 mm. It shortens the stroke only - it never extends it past 70 mm, and it is an end stop, not a mid-stroke lock.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, S45C hard-chrome rod and fixed TPU bumpers at both ends that absorb end-of-stroke energy. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be fitted in the body slots. FA flange and LB foot mounts plus I and Y rod knuckles bolt straight to the standard face; the port is 1/8" PT and the female rod thread is M12x1.75.
