About the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-40S
The ACEJ32X100-40S is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 100 mm stroke by up to 40 mm on site, giving a usable range of 60-100 mm without changing the cylinder. At 0.5 MPa the 32 mm bore delivers 402.1 N push and 345.6 N pull, rising to 563 N push at 0.7 MPa. In practice, plan on roughly 240 N of real work at 0.5 MPa, and for vertical lifts expect about 20 kg with a 2:1 margin (the theoretical lift is about 41 kg).
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs, guards and gantries. A hard-anodized aluminium body with a hard-chrome plated S45C rod resists wear, fixed TPU bumpers absorb end-of-stroke energy, and the fitted -S magnet accepts CMSE / DMSE switches for end-position sensing. Operating range is 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s.

Where the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-40S Is Used
Fixture clamping on CNC pallets
The 60-100 mm trim range lets one cylinder serve several fixture heights, and 402.1 N push at 0.5 MPa secures aluminium or small steel parts between machining cycles.
Packaging line pusher gates
A 100 mm stroke diverts cartons or trays at line speed up to 500 mm/s, while the fitted magnet and a DMSE switch confirm the gate is fully retracted before product passes.
Lab sample press station
About 240 N of usable force at 0.5 MPa gives gentle, repeatable pressing of vials or test coupons, and the compact body fits inside a benchtop guard where a full-length profile cylinder would not.
Is the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-40S the Right Cylinder?
Check the load both ways before committing: the smaller 25 mm bore pushes only 245.4 N at 0.5 MPa, while the larger 40 mm bore reaches 628.3 N, so the 32 mm class at 402.1 N sits between them for medium clamping and positioning. Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock - on air loss the piston still drifts, so add a separate holding valve for suspended loads. FA flange or LB foot mounting bolts to the standard ISO 21287 face, and this model 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 ACEJ32X100-40S FAQ
At 0.5 MPa it pushes 402.1 N and pulls 345.6 N; at 0.7 MPa push rises to 563 N (pull 483.8 N). Theoretical maximum is 82 kgf at 1.0 MPa. The ordered stroke is 100 mm with a 40 mm adjustment window, so the extend stroke can be trimmed anywhere from 60 to 100 mm via the external stop screw. Speed range is 30-500 mm/s and operating pressure is 0.15-1.0 MPa (22-145 psi).
It is an ISO 21287 compact cylinder - about 50% shorter in mounting length than an ISO 15552 profile cylinder - with a hard-anodized aluminium body, hard-chrome plated S45C rod and fixed TPU bumpers at both ends. This model carries the optional -S magnet, so CMSE or DMSE reed or solid-state switches can be clipped into the body slots to signal extend and retract positions. FA flange and LB foot mountings bolt straight to the standard face.
