Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-50B
The AirTAC Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-50B is a genuine double acting, adjustable stroke ISO 21287 compact air cylinder with a Ø32mm bore and 100mm stroke, 1/8" air ports and a hard-anodized aluminium body. Its short compact envelope saves about 50% of the mounting length of an ISO 15552 profile cylinder.

About the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-50B
A double acting ISO 21287 compact cylinder with an adjustable extend stroke, the ACEJ32X100-50B pairs a 32 mm bore with a 100 mm stroke and a 50 mm adjustment window. An external stop screw trims the extend stroke on site anywhere between 50 and 100 mm, so one cylinder serves several station depths. At 0.5 MPa it pushes 402.1 N and pulls 345.6 N; at 0.7 MPa push rises to 563 N, with a theoretical maximum of 82 kgf at 1.0 MPa. The hard-anodized aluminium body and S45C hard-chrome plated rod keep wear down in daily production duty.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters in tight jig plates and guarded cells. A practical sizing note: treat roughly 0.6 of the push force as usable work, so about 241 N, which lifts roughly 24 kg vertically - halve that to about 12 kg if you want a 2:1 margin on a vertical lift. The B code gives a male rod thread on the 12 mm rod, the port is 1/8" PT, and fixed TPU bumpers absorb end-of-stroke shock at both ends. Speed range is 30-500 mm/s over 0.15-1.0 MPa (22-145 psi).

Where the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-50B Is Used
Multi-part jig clamping
The 50-100 mm adjustable extend stroke lets one cylinder serve jig plates with different part heights, with 402.1 N push at 0.5 MPa holding steel brackets firmly during drilling.
Small press-fit station
About 241 N of usable working force at 0.5 MPa is enough to press dowel pins into aluminium housings on an electronics assembly bench, with the stop screw setting the exact bottom position.
Packaging line stopper
Mounted under a conveyor, the 100 mm stroke raises a stop blade for cartons up to roughly 12 kg with a 2:1 vertical margin, and the 50 mm window tunes the blade height per product size.
Is the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-50B the Right Cylinder?
At 402.1 N push at 0.5 MPa, this 32 mm bore suits clamping and pressing jobs in the 240 N working range; 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. The stop screw is a mechanical end stop only - it shortens the extend stroke but does not hold a load if air is lost. Mounting: FA flange or LB foot bolt to the ISO 21287 face, with I and Y rod knuckles available. If you need position feedback, order the -S version, since this model has no magnet and no CMSE / DMSE sensor 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 ACEJ32X100-50B 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. It is double acting with an adjustable extend stroke: the -50 stop screw trims the 100 mm stroke down to 50 mm. 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, fluid air filtered to 40 um. Port is 1/8" PT, rod is 12 mm with male thread (B code).
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits where a full-length cylinder will not. Fixed TPU bumpers at both ends absorb end-of-stroke shock. FA flange and LB foot mountings plus I/Y rod knuckles bolt to the standard face. This model has no magnet; the optional -S code adds one so CMSE or DMSE switches can be mounted for end-position sensing.
