About the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X150-50
The ACEJ32X150-50 is a double acting ISO 21287 compact cylinder with an adjustable extend stroke. A 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, with a theoretical peak of 82 kgf at 1.0 MPa. The -50 code means an external stop screw trims the 150 mm extend stroke by up to 50 mm on site, giving a usable range of 100-150 mm without changing the cylinder.
The short ISO 21287 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. A hard-anodized aluminium body pairs with an S45C hard-chrome plated 12 mm rod, and fixed TPU bumpers absorb end-of-stroke shock at both ends. As a rule of thumb, plan for roughly 240 N (about 24 kg) of real work at 0.5 MPa, which corresponds to lifting around 12 kg vertically with a 2:1 margin. Note this unit ships without a magnet; order the -S code if you need CMSE / DMSE switch sensing.

Where the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X150-50 Is Used
Fixture clamping on CNC pallets
The 100-150 mm adjustable extend range lets a machinist dial in clamp travel per pallet, while 402.1 N push at 0.5 MPa seats parts against hard stops in milling and turning fixtures.
Carton ejection from magazine feeders
A packaging line pushing cartons off a stack uses the trimmed stroke to match carton height, and the compact body fits inside the feeder frame where a longer profile cylinder cannot.
Product diverters on conveyor lines
With 345.6 N pull at 0.5 MPa the rod retracts a pusher gate reliably, and the 50 mm adjustment window lets technicians fine-tune divert position without swapping cylinders.
Is the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X150-50 the Right Cylinder?
At 32 mm bore this model sits between the 25 mm size (245.4 N push at 0.5 MPa) and the 40 mm size (628.3 N push at 0.5 MPa), so pick 32 mm when your load needs roughly 240 N of usable force at 0.5 MPa. The 150 mm stroke is within the 200 mm maximum standard stroke for this bore. Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock: on air loss the piston can still drift, so do not rely on it to hold a load. FA flange and LB foot mountings bolt to the ISO 21287 face, and the optional -S magnet enables CMSE / DMSE switches if position feedback is needed later.
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 ACEJ32X150-50 FAQ
At 0.5 MPa it pushes 402.1 N and pulls 345.6 N; at 0.7 MPa push is 563 N and pull 483.8 N; theoretical maximum is 82 kgf at 1.0 MPa. The 32 mm bore has a 12 mm rod with M8x1.25 female thread and a 1/8" port. Operating pressure is 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, and the extend stroke is adjustable from 100 to 150 mm via the -50 stop screw.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and FA flange or LB foot brackets bolt straight to the standard face. Sensing is not included on this unit: the magnet is the optional -S code, so order ACEJ32X150-50S if you want CMSE / DMSE reed or solid-state switches. A fixed TPU bumper at each end absorbs end-of-stroke impact.
