About the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-40SB
The ACEJ32X100-40SB is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 100 mm stroke by up to 40 mm, giving a usable range of 60-100 mm on site. At 0.5 MPa the 32 mm bore delivers 402.1 N push and 345.6 N pull, rising to 563 N push at 0.7 MPa. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding where a full-length body will not fit.
In practice, plan on roughly 241 N (about 24 kgf) of real work at 0.5 MPa, and expect it to lift about 20 kg vertically once a 2:1 margin is applied. The male rod thread (B code) suits rod knuckles and tooling plates, while the fitted -S magnet accepts CMSE / DMSE switches for end-position sensing. A fixed TPU bumper at each end absorbs end-of-stroke energy, and FA flange or LB foot brackets 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 ACEJ32X100-40SB Is Used
Fixture clamping on CNC pallets
The 60-100 mm trim range lets one cylinder serve several pallet heights, and 402.1 N push at 0.5 MPa holds aluminium workpieces firmly during machining.
Packaging line pushers
A short ISO 21287 body fits under low guard rails, while the fitted magnet and CMSE switch confirm each 100 mm or trimmed push completed.
Small pallet ejector stations
With about 20 kg vertical-lift capability at a 2:1 margin, the male-thread rod drives a knuckle lever to tip cartons off a takeaway conveyor.
Is the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-40SB the Right Cylinder?
Size against neighbours: the 25 mm bore gives 245.4 N push at 0.5 MPa, while the 40 mm bore reaches 628.3 N - pick the 32 mm when your load sits between those bands. The 1/8" port matches bores 32-63, and the female-thread rod version (no B code) is available if you prefer a nut-on-rod connection. Remember the stop screw shortens the extend stroke only; it is not a mid-stroke lock, so on air loss the piston still drifts. If you need position feedback, this model already carries the optional -S magnet for CMSE / DMSE switches.
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 ACEJ32X100-40SB 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, with a theoretical maximum of 82 kgf at 1.0 MPa. It 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, with a 1/8" port and 12 mm hard-chrome plated S45C rod.
The -40 code means an external stop screw can shorten the 100 mm extend stroke by up to 40 mm, so you set any extend length between 60 and 100 mm without swapping cylinders. A fixed TPU bumper at both ends absorbs end-of-stroke energy but never locks or holds a load. Because the -S magnet is fitted, CMSE / DMSE reed or solid-state switches mount directly in the body slots for position feedback.
