About the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-30B
The ACEJ32X100-30B is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 100 mm stroke anywhere within the ordered 30 mm window, giving a usable range of 70-100 mm without changing the cylinder. At 0.5 MPa it pushes with 402.1 N and pulls with 345.6 N, and the male rod thread (the B code) bolts straight into linkage arms and tooling plates.
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 slide assemblies. For sizing, plan on roughly 240 N of real work at 0.5 MPa (about 60% of the rating), which is a vertical lift of around 24 kg - or about 12 kg with a 2:1 margin. FA flanges, LB feet and I/Y rod knuckles mount on the standard face, and the optional -S magnet enables CMSE / DMSE switches; without -S no magnet is fitted. Speed range is 30-500 mm/s.

Where the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-30B Is Used
Fixture clamp stroke tuning
On a machining-centre jig, the 30 mm window lets the setter dial the clamp stroke between 70 and 100 mm to clear a swarf guard while still seating the part, using the 402.1 N push at 0.5 MPa.
Packaging pusher with male-thread linkage
A carton pusher on a food line uses the B male rod thread for a quick-release clevis, with the 345.6 N pull stroke retracting the paddle clear of the 100 mm conveyor gap.
Small press ejection
In a light stamping die, the cylinder ejects parts with 563 N available at 0.7 MPa, and the stop screw sets a repeatable 70 mm ejection height for shallow parts.
Is the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-30B the Right Cylinder?
At 32 mm bore this unit delivers 402.1 N push at 0.5 MPa - a step up from the 25 mm bore (245.4 N) if your clamp or slide needs more force, while the 40 mm bore (628.3 N) is the next size if 402 N is marginal. The -30 window suits fixtures where the final stroke is tuned on the machine, trimming down to 70 mm; if you need the full 100 mm always, the fixed-stroke ACE32X100 does the same job. Remember the stop screw is an end stop only - on air loss the rod drifts, so add a valve or external lock for load holding. Order the -S code if you need position sensing.
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 ACEJ32X100-30B FAQ
At 0.5 MPa it pushes 402.1 N and pulls 345.6 N; at 0.7 MPa push rises to 563 N and pull to 483.8 N, with a theoretical maximum of 82 kgf at 1.0 MPa. The -30 code is a 30 mm adjustment window: an external stop screw shortens the 100 mm extend stroke by up to 30 mm, so the working range is 70-100 mm. It cannot lengthen the stroke beyond 100 mm, and the stop is not a mid-stroke lock - on air loss the piston still drifts.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, S45C hard-chrome rod and fixed TPU bumpers at both ends. Position sensing requires the optional -S magnet, which allows CMSE / DMSE switches; this model has no S code, so no magnet is fitted. FA flange, LB foot and I/Y rod knuckles bolt to the standard mounting face, and the air port is 1/8" PT.
