About the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-75SB
The ACEJ32X100-75SB is a double acting ISO 21287 compact cylinder with an adjustable extend stroke. A 32 mm bore delivers 402.1 N push and 345.6 N pull at 0.5 MPa, rising to 563 N at 0.7 MPa, with a theoretical peak of 82 kgf at 1.0 MPa. The -75 code means an external stop screw trims the 100 mm extend stroke down to as little as 25 mm on site, so one cylinder covers a 25-100 mm working range without re-ordering. This unit carries the optional -S magnet and a male rod thread (B code).
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters inside tight machine frames and guarding. Because the magnet is fitted, CMSE or DMSE reed and solid-state switches mount directly in the body slots for end-of-stroke signalling. In practice, plan on roughly 240 N of usable push at 0.5 MPa (about 60% of rating), which corresponds to lifting around 12 kg vertically with a 2:1 margin - enough for small pallets, clamps or gate leaves. FA flange, LB foot and I/Y knuckle hardware bolt straight to the ISO 21287 face.

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 ACEJ32X100-75SB Is Used
Fixture clamp with tunable stroke
On a CNC milling fixture, the 25-100 mm adjustable window lets the machinist shorten the clamp stroke per part family without swapping cylinders, with 402.1 N push holding workpieces against 0.5 MPa supply.
Packaging line pusher station
A carton diverter on a snack-food conveyor uses the male rod thread with a Y knuckle to kick boxes between lanes, while the fitted magnet and a DMSE switch confirm each push completed.
Small parts lift in a test rig
A laboratory lift table raising roughly 12 kg sensor fixtures benefits from the compact body that fits inside the rig frame, taking about 50% less mounting length than an ISO 15552 profile cylinder.
Is the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-75SB the Right Cylinder?
At 32 mm bore you sit mid-range: a 25 mm bore gives 245.4 N push at 0.5 MPa, while a 40 mm bore raises it to 628.3 N - step up if your tooling mass exceeds about 12 kg of vertical lift at a 2:1 margin. Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock: on air loss the piston still drifts, so add a valve or external stop if position must hold. Match FA flange or LB foot mounting to your fixture, and keep the -S magnet (fitted here) so CMSE/DMSE switches remain available. Speed range is 30-500 mm/s across 0.15-1.0 MPa (22-145 psi).
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 ACEJ32X100-75SB FAQ
At 0.5 MPa it pushes 402.1 N and pulls 345.6 N; at 0.7 MPa push is 563 N and pull 483.8 N; theoretical maximum is 82 kgf at 1.0 MPa. It is double acting with a 75 mm adjustment window on the 100 mm extend stroke (usable 25-100 mm), 1/8" PT ports, a 12 mm male-thread rod, operating pressure 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and -20 to +70 C operation on air filtered to 40 um.
The hard-anodized aluminium ISO 21287 body with an S45C hard-chrome rod saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into cramped gantries. Turning the external stop screw shortens the extend stroke anywhere within the ordered 75 mm window - it cannot lengthen travel past 100 mm. Fixed TPU bumpers at both ends absorb end-of-stroke impact, and because the -S magnet is fitted on this model, CMSE or DMSE switches can be clipped into the body slots for position feedback.
