About the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-40B
This AirTAC ACEJ32X100-40B is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: a 32 mm bore driving a 12 mm hard-chrome-plated S45C rod, delivering 402.1 N push and 345.6 N pull at 0.5 MPa (563 N push at 0.7 MPa). The external stop screw trims the 100 mm stroke by up to 40 mm on site, giving a usable extend range of 60-100 mm without changing the cylinder. Air supply runs 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s, with fixed TPU bumpers at both ends.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs, guarding and gantry frames. The hard-anodized aluminium body with roller-burnished bore resists wear, and the male rod thread (B code) bolts straight to external tooling. As a sizing rule of thumb, plan on roughly 240 N of usable work at 0.5 MPa (about 60% of the push rating), which is around 24 kg of vertical lift with a margin - enough for clamping fixtures, small press heads or gate panels. Note the stop screw is an end stop only: on air loss the rod still drifts, so it is not a load-holding lock.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-40B Is Used
Clamp fixture on a CNC milling jig
The 402.1 N push at 0.5 MPa holds aluminium housings against locators, and the 60-100 mm adjustable range lets the setter dial in clamp travel without swapping cylinders.
Small press or marking head
About 24 kg of vertical lift equivalent with margin suits light staking, embossing or ink-marking heads on short-stroke stations where body length is tight.
Slide gate on a packaging machine
The male rod thread drives a gate linkage directly, and the compact body fits inside guarding where a full-length profile cylinder would not clear the frame.
Is the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-40B the Right Cylinder?
At 32 mm bore this sits in the mid-light class: step down to a 25 mm bore (245.4 N push at 0.5 MPa) for lighter clamps, or up to a 40 mm bore (628.3 N push) when the load grows. The 100 mm stroke is well inside the 200 mm maximum standard stroke for this bore, so no made-to-order stroke is needed. The 40 mm window suits jobs where the final stroke is tuned during commissioning, such as locating stops or clamp travel. Choose the FA flange or LB foot to match the fixture, and remember the magnet is the optional -S code - this unit has none, so no CMSE or DMSE switch can be fitted unless you order -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 ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-40B FAQ
At 0.5 MPa it pushes 402.1 N and pulls 345.6 N; at 0.7 MPa push rises to 563 N and pull to 483.8 N, with a theoretical maximum of 82 kgf at 1.0 MPa. The 32 mm bore takes a 1/8" port, runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C. The stop screw shortens the 100 mm extend stroke by up to 40 mm (usable range 60-100 mm), and the rod end is male thread (B code) with PT port thread.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with fixed TPU bumpers at both ends absorbing end-of-stroke shock. FA flange and LB foot mount on the standard face, plus I and Y rod knuckles. Position sensing requires the optional -S magnet: this model (no S code) has no magnet, so CMSE or DMSE switches cannot be used unless you order the -S version.
