About the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X70-50
This ACEJ32X70-50 is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 70 mm stroke by up to 50 mm, giving a usable range of 20-70 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. A practical rule of thumb is to plan for about 60% of the push rating, so roughly 240 N of real work - and in vertical terms that means it lifts about 12 kg with a 2:1 margin.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs, guards and gantries. The hard-anodized aluminium body carries a hard-chrome plated S45C rod, a fixed TPU bumper sits at each end, and FA flange or LB foot mounts plus I/Y rod knuckles bolt straight to the standard face. No magnet is fitted on this version; order the -S code if you need CMSE / DMSE switch sensing.

Where the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X70-50 Is Used
Fixture clamping on CNC machining centers
The 20-70 mm adjustable window lets one cylinder serve several fixture heights, with 402.1 N push at 0.5 MPa holding aluminum or steel parts during milling.
Packaging line product stops
Short ISO 21287 body fits under conveyor guard rails where a full-length profile cylinder will not, trimming the stop position on site within the 50 mm window.
Press-fit of small electronics housings
About 12 kg vertical lift capacity with a 2:1 margin covers light press and snap-fit work on connector and sensor assemblies at 0.5-0.7 MPa.
Is the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X70-50 the Right Cylinder?
At 402.1 N push (0.5 MPa) this 32 mm bore suits clamping and positioning loads up to roughly 240 N in continuous duty. Step down to a 25 mm bore (245.4 N push) for lighter fixtures, or up to a 40 mm bore (628.3 N push) when the load grows. Remember the stop screw is a mechanical end stop only - it sets the extend stroke but does not lock the piston if air is lost. Choose the female M8x1.25 rod thread shown here, or add B for a male thread; PT ports are standard and G is available. If you need position feedback, specify the -S magnet code so CMSE / DMSE switches can be fitted.
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 ACEJ32X70-50 FAQ
Push is 402.1 N and pull 345.6 N at 0.5 MPa; at 0.7 MPa push reaches 563 N and pull 483.8 N, with a theoretical maximum of 82 kgf at 1.0 MPa. It is double acting with a 70 mm stroke adjustable down to 20 mm via the -50 stop screw, 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 12 mm rod, M8x1.25 female thread and 1/8" ports.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and FA flange or LB foot mounts plus I/Y rod knuckles bolt directly to the standard face. A fixed TPU bumper at each end absorbs end-of-stroke energy. Position sensing requires the optional -S magnet code - this model has no magnet fitted, so no CMSE or DMSE switch can be mounted unless you order -S.
