Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-75B
The AirTAC Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-75B is a genuine double acting, adjustable stroke ISO 21287 compact air cylinder with a Ø32mm bore and 100mm stroke, 1/8" air ports and a hard-anodized aluminium body. Its short compact envelope saves about 50% of the mounting length of an ISO 15552 profile cylinder.

About the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-75B
The ACEJ32X100-75B is a double acting ISO 21287 compact cylinder with an adjustable extend stroke. Its 32 mm bore delivers 402.1 N push and 345.6 N pull at 0.5 MPa, 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.
The -75 code gives a 75 mm adjustment window: an external stop screw trims the 100 mm extend stroke anywhere down to 25 mm on site, no disassembly needed. With 402.1 N of push, plan on roughly 241 N of usable work at 0.5 MPa, which lifts about 20 kg vertically with a 2:1 margin. The male rod thread (B code) bolts straight to I/Y knuckles, and FA flange or LB foot mounts fit the standard ISO 21287 face. The optional -S magnet enables CMSE / DMSE switches; this unit has no magnet fitted.

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 ACEJ32X100-75B Is Used
Jig clamping with trimmed stroke
On a machining fixture, the stop screw sets the clamp travel anywhere from 25 to 100 mm, so one cylinder serves several part heights without swapping hardware.
Small pallet lift-and-push
About 20 kg of vertical lift at a 2:1 margin makes the 32 mm bore a fit for raising small totes or pallet stops on assembly lines running 0.5 MPa.
Gate indexing on packaging lines
Speeds of 30-500 mm/s and the male rod thread let this cylinder drive product gates and diverters, with the 75 mm window matching different gate openings.
Is the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-75B the Right Cylinder?
Size check: a 25 mm bore gives 245.4 N push at 0.5 MPa, while a 40 mm bore raises it to 628.3 N - pick the 32 mm when your load sits between those bands. Remember the stop screw is a mechanical end stop, not a mid-stroke lock, so the rod still drifts if air is lost. If you need position feedback, order the -S code so CMSE / DMSE switches can ride the body slots; this model ships without a magnet.
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 ACEJ32X100-75B FAQ
At 0.5 MPa it pushes 402.1 N and pulls 345.6 N; at 0.7 MPa it pushes 563 N and pulls 483.8 N, with a theoretical maximum of 82 kgf at 1.0 MPa. The -75 code means an external stop screw shortens the 100 mm extend stroke by up to 75 mm, giving a usable range of 25-100 mm. It is double acting, runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), and moves at 30-500 mm/s.
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. FA flange, LB foot and FTC brackets bolt to the standard face, and I/Y rod knuckles suit the male rod thread. Sensors need the optional -S magnet - CMSE / DMSE switches then mount in the body slots; without -S no magnet is fitted.
