About the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-50SB
The ACEJ32X100-50SB is a double acting ISO 21287 compact cylinder with an adjustable extend stroke. Its 32 mm bore delivers 402.1 N push and 345.6 N pull at 0.5 MPa, rising to 563 N at 0.7 MPa, with a theoretical maximum of 82 kgf at 1.0 MPa. The -50 code means an external stop screw trims the 100 mm extend stroke anywhere in a 50 mm window, so one cylinder covers a 50-100 mm working range without swapping parts.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters in tight jigs and guarded cells. A hard-anodized aluminium body carries an S45C hard-chrome rod, and fixed TPU bumpers absorb end-of-stroke shock. In practice, plan for roughly 241 N of real work at 0.5 MPa (about 0.6 of the push rating), which lifts about 20 kg vertically with a 2:1 margin. The fitted -S magnet accepts CMSE / DMSE switches, and the male rod thread (B code) bolts straight into standard fixtures.

Where the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-50SB Is Used
Fixture clamp trimming
On a machining fixture for aluminium housings, the stop screw sets any extend stroke from 50 to 100 mm, so one cylinder serves several part heights with about 241 N of usable clamp force at 0.5 MPa.
Small pallet lift-assist
A vertical lift point on a compact assembly cell raises about 20 kg parts with a 2:1 margin, using the 402.1 N push at 0.5 MPa and the short body that fits where a full-length profile cylinder cannot.
Gantry pick with position check
The fitted -S magnet drives CMSE / DMSE switches for extend and retract confirmation on a pick-and-place gantry, with the 50-100 mm adjustable range matching varied product pitches.
Is the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-50SB the Right Cylinder?
Size check both ways: a 25 mm bore gives only 245.4 N push at 0.5 MPa, so it is marginal for loads near 20 kg; a 40 mm bore pushes 628.3 N if you need headroom. This 32 mm model suits mid-range clamping and lifting between those two. Remember the stop screw is a mechanical end stop, not a mid-stroke lock - on air loss the rod still drifts, so add a separate holding valve for suspended loads. Mount with FA flange or LB foot on the ISO 21287 face; the male thread (B) suits clevis knuckles. If you need position feedback, this unit already carries the -S magnet for CMSE / DMSE switches.
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 ACEJ32X100-50SB 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; the theoretical maximum is 82 kgf at 1.0 MPa. The -50 code gives a 50 mm adjustment window: an external stop screw shortens the 100 mm extend stroke on site, giving a usable 50-100 mm range. It shortens the stroke only - it never extends it past 100 mm, and it is an end stop, not a mid-stroke lock.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body and S45C hard-chrome rod. Fixed TPU bumpers at both ends absorb end-of-stroke energy. FA flange and LB foot mount on the standard face, and the male rod thread suits I or Y knuckles. The -S magnet is fitted on this model, so CMSE / DMSE reed or solid-state switches can be mounted; without the S code there is no magnet. Operating range is 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, -20 to +70 C.
