About the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X70-10S
The ACEJ32X70-10S is a double acting AirTAC compact cylinder built to ISO 21287, with a 32 mm bore and a 70 mm stroke that an external stop screw can trim anywhere in a 10 mm window, giving a usable extend range of 60-70 mm. At 0.5 MPa it pushes 402.1 N and pulls 345.6 N; at 0.7 MPa those rise to 563 N and 483.8 N, with a theoretical 82 kgf at 1.0 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.
For sizing the load, plan on roughly 241 N of real work at 0.5 MPa (about 0.6 of the push rating), which corresponds to lifting about 20 kg vertically with a 2:1 margin. The hard-anodized aluminium body carries a 12 mm S45C hard-chrome-plated rod with a female M8x1.25 thread, and the -S code on this model means the magnet is fitted, so CMSE / DMSE reed or solid-state switches can be clamped straight onto the body slots. Air supply is filtered to 40 um, pressure runs 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and fixed TPU bumpers absorb end-of-stroke shock at both ends.

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 ACEJ32X70-10S Is Used
Fixture clamping on CNC pallets
The 60-70 mm adjustable extend range lets a jig builder dial in exact clamp position on machining pallets, with 402.1 N of push at 0.5 MPa holding parts against hard stops.
Packaging line pusher arms
A short body that saves about 50% of the mounting length of an ISO 15552 profile cylinder fits between conveyor frames, while the fitted magnet feeds CMSE switch signals to the PLC.
Lab sample press station
Gentle 30-500 mm/s speed control and a 10 mm trim window suit small sample pressing and indexing tasks, lifting about 20 kg vertically with a 2:1 margin.
Is the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X70-10S the Right Cylinder?
At 402.1 N push at 0.5 MPa this bore sits in the mid-light class: step down to the 25 mm bore (245.4 N push) for lighter clamping, or up to the 40 mm bore (628.3 N push) when the load grows. The 10 mm adjuster only shortens the extend stroke, so order the full 70 mm and trim down on site; it is a mechanical end stop, not a mid-stroke lock, so the rod can still drift if air is lost. FA flange and LB foot mountings bolt to the ISO 21287 face, and because the -S magnet is fitted, CMSE / DMSE switches are ready to mount for end-of-stroke signalling.
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 ACEJ32X70-10S 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; theoretical maximum is 82 kgf at 1.0 MPa. For real work, size around 241 N (about 0.6 of push), which is roughly 20 kg of vertical lift with a 2:1 safety margin. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, air filtered to 40 um, temperature -20 to +70 C.
The -10 code gives a 10 mm adjustment window: an external stop screw shortens the 70 mm extend stroke on site, so the usable range is 60-70 mm. It cannot lengthen the stroke past 70 mm, and it is an end stop only, not a load-holding brake. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches mount in the body slots. The 1/8" port suits the 32 mm bore, FA flange or LB foot mountings bolt to the ISO 21287 face, and the fixed TPU bumpers at both ends absorb end-of-stroke energy.
