About the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X70-50S
The ACEJ32X70-50S is a double acting ISO 21287 compact cylinder with a 32 mm bore and a 70 mm stroke that the -50 stop screw trims down to 20 mm on site. At 0.5 MPa it pushes 402.1 N and pulls 345.6 N, rising to 563 N at 0.7 MPa, with a theoretical peak of 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 fixtures and guarding where a full-length body will not fit.
The hard-anodized aluminium body carries a hard-chrome plated S45C rod with a female M8x1.25 thread, and a fixed TPU bumper at each end absorbs end-of-stroke shock. This model carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be clamped into the body slots for end-position sensing. Plan on roughly 240 N (about 24 kg) of usable push at 0.5 MPa, which lifts about 12 kg vertically with a 2:1 margin.

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 ACEJ32X70-50S Is Used
Fixture clamping on CNC pallets
The 402.1 N push at 0.5 MPa clamps aluminium housings in machining fixtures, and the 20-70 mm trim lets one cylinder serve several pallet sizes without re-plumbing.
Reject pusher on packaging lines
A short 70 mm body kicks off-spec cartons from a conveyor lane, with CMSE switches confirming extend and retract at each cycle.
Sample press in lab automation
About 24 kg of usable force at 0.5 MPa presses test cups onto sample trays, and the adjustable window dials in the exact press depth per recipe.
Is the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X70-50S the Right Cylinder?
Size both ways: the 25 mm bore gives 245.4 N push at 0.5 MPa for lighter clamping, while the 40 mm bore reaches 628.3 N when the load grows. If the stop screw must hold position during a power loss, remember it is a mechanical end stop only - the rod still drifts when air is removed, so add an external lock for load holding. FA flange or LB foot mounts bolt to the ISO 21287 face, and the fitted magnet pairs with CMSE / DMSE switches. Air supply: 0.15-1.0 MPa (22-145 psi), filtered to 40 um, speed 30-500 mm/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 ACEJ32X70-50S 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 -50 stop screw shortens the 70 mm extend stroke by up to 50 mm, giving a usable range of 20-70 mm. It runs double acting on 0.15-1.0 MPa (22-145 psi) air 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 fixed TPU bumper at each end to soften stroke ends. This model carries the optional -S magnet, so CMSE or DMSE reed or solid-state switches mount directly in the body slots. FA flange and LB foot mounts plus I/Y rod knuckles bolt to the standard ISO 21287 face.
