About the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X150-20
The ACEJ32X150-20 is a double acting AirTAC compact cylinder built to ISO 21287, with a 32 mm bore and a 150 mm stroke that an external stop screw can trim by up to 20 mm, giving a usable extend range of 130-150 mm. At 0.5 MPa it pushes 402.1 N and pulls 345.6 N, rising to 563 N on the extend stroke 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, guarding and gantries where a full-length body cannot fit.
For sizing the load, plan on roughly 241 N of real work at 0.5 MPa, which is about 24 kg of vertical lift with a 2:1 margin. The hard-anodized aluminium body carries a 12 mm S45C hard-chrome rod with a female M8x1.25 thread, and 1/8" (PT) ports. A fixed TPU bumper at each end absorbs end-of-stroke energy, and the rod end is female threaded. Note that the stop screw sets the end of stroke only; on air loss the piston can still drift, so it is not a load lock. The magnet is not fitted on this code - order the -S variant if you need CMSE / DMSE switch position sensing.

Where the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X150-20 Is Used
Fixture clamping on CNC pallets
The 402.1 N push at 0.5 MPa clamps aluminium or small steel workpieces, and the 20 mm window lets one cylinder serve several pallet designs between 130 and 150 mm of stroke.
Packaging line push-off stations
A short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits under low conveyor frames while the 150 mm stroke clears the product lane.
Lab and test rig actuation
Speeds of 30-500 mm/s and the 130-150 mm adjustable range suit bench-top press and sample-feed rigs running on 0.15-1.0 MPa (22-145 psi) shop air.
Is the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X150-20 the Right Cylinder?
At 402.1 N push at 0.5 MPa, this 32 mm bore sits between the 25 mm bore (245.4 N push) and the 40 mm bore (628.3 N push); step up if your fixture needs more than about 240 N of working force. The 150 mm stroke is within the 200 mm maximum standard stroke for this bore, so no made-to-order build is required. Mount it on the ISO 21287 face with FA flange or LB foot hardware, and add I or Y rod knuckles where the tooling needs a swivel. If your controller needs end-position feedback, order the -S code so CMSE / DMSE switches can be fitted - this model has no magnet as coded.
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 ACEJ32X150-20 FAQ
This 32 mm bore model delivers 402.1 N push and 345.6 N pull at 0.5 MPa, and 563 N push / 483.8 N pull at 0.7 MPa, with a theoretical maximum of 82 kgf at 1.0 MPa. The ordered stroke is 150 mm and the -20 stop screw trims the extend stroke by up to 20 mm, so the usable range is 130-150 mm. Ports are 1/8" PT, the rod is 12 mm with a female M8x1.25 thread, and speed is 30-500 mm/s.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body, threaded aluminium covers, and a hard-chrome plated S45C rod; a fixed TPU bumper at each end absorbs end-of-stroke energy. FA flange and LB foot mounts bolt to the standard ISO 21287 face. Position sensing needs the optional -S magnet code - this model, coded without S, has no magnet, so CMSE / DMSE switches cannot be fitted unless you order the -S variant.
