About the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ40X50-10
The ACEJ40X50-10 is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 50 mm stroke by up to 10 mm on site, giving a usable range of 40-50 mm without changing the cylinder. At 0.5 MPa the 40 mm bore delivers 628.3 N push and 571.8 N pull, rising to 879.6 N at 0.7 MPa, with a theoretical maximum of 128.1 kgf at 1.0 MPa.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight guarding and fixture pockets. As a planning figure, treat roughly 377 N (about 60% of the push rating) as the practical work force, which corresponds to lifting about 32 kg vertically 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 a fixed TPU bumper at each end absorbs end-of-stroke impact.

Where the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ40X50-10 Is Used
Fixture clamping on CNC pallets
The 628.3 N push at 0.5 MPa clamps aluminium housings on machining pallets, and the 10 mm stop window lets the setter dial the clamp position after the fixture is bolted down.
Small part press-fit station
With about 377 N of practical work force, the cylinder presses bushings into pump housings on an assembly bench, retracting at up to 500 mm/s to keep cycle time short.
Gate stop on packaging lines
The compact body fits inside conveyor guarding where a full-length profile cylinder cannot, stopping cartons on a 40-50 mm extend stroke between 1/8" ports.
Is the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ40X50-10 the Right Cylinder?
At 628.3 N push at 0.5 MPa this 40 mm bore sits between the 32 mm bore (402.1 N) and the 50 mm bore (981.7 N), so pick it for mid-range clamping and lifting where the smaller bore is marginal and the 50 mm is oversized. The 10 mm window suits fixtures where the exact stop position is finalized after installation. Remember the stop screw only shortens the extend stroke and is a mechanical end stop, not a mid-stroke lock: on air loss the piston still drifts. FA flange or LB foot mounting bolts to the ISO 21287 face, and if position feedback is needed later, order the -S variant so CMSE / DMSE switches can be used; this model has no magnet 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 ACEJ40X50-10 FAQ
At 0.5 MPa it pushes 628.3 N and pulls 571.8 N; at 0.7 MPa push is 879.6 N and pull 800.5 N, with a theoretical maximum of 128.1 kgf at 1.0 MPa. The -10 code is a 10 mm adjustment window: a stop screw on the front cover shortens the 50 mm extend stroke by up to 10 mm, so the working range is 40-50 mm. It 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.
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 absorb end-of-stroke impact. FA flange and LB foot mounts bolt straight to the standard face, and the rod end is a female M8x1.25 thread with 1/8" PT ports. Position sensing requires the optional -S magnet code; this model has no magnet, so CMSE / DMSE switches cannot be fitted unless you order the -S variant.
