About the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-20SB
A double acting ISO 21287 compact cylinder, the ACEJ32X100-20SB pairs a 32 mm bore with a 100 mm stroke that an external stop screw can trim by up to 20 mm on site, giving a usable extend range of 80-100 mm. At 0.5 MPa it pushes 402.1 N and pulls 345.6 N; at 0.7 MPa those rise to 563 N and 483.8 N, with a theoretical ceiling of 82 kgf at 1.0 MPa. The male rod thread (B code) and PT ports suit direct tooling attachment.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight guards and fixtures. Because the -S magnet is fitted, CMSE / DMSE reed or solid-state switches can be mounted anywhere along the body slots. For sizing, plan on roughly 241 N of real work at 0.5 MPa (about 0.6 of the push figure), which lifts about 20 kg vertically with a 2:1 margin. A fixed TPU bumper at each end absorbs end-of-stroke shock, and speed spans 30-500 mm/s.

Where the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-20SB Is Used
Fixture clamp with trimmable stroke
On a CNC jig the stop screw lets machinists dial the 100 mm extend stroke down to 80 mm for shorter part stacks, with 402.1 N of clamp force at 0.5 MPa.
Packaging line pusher
The compact body fits under low conveyor guards where a full-length profile cylinder cannot, pushing cartons with about 241 N of usable force at 0.5 MPa.
Position-verified ejector
With the fitted -S magnet, CMSE / DMSE switches confirm extend and retract on a small-parts ejection station, while the male rod thread drives the ejector pin directly.
Is the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-20SB the Right Cylinder?
At this force class the 32 mm bore delivers 402.1 N push at 0.5 MPa; step down to a 25 mm bore (245.4 N) for lighter clamping or up to a 40 mm bore (628.3 N) when the load grows. Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock, so the piston still drifts if air is lost. FA flange or LB foot mountings bolt to the ISO 21287 face, and the fitted -S magnet lets CMSE / DMSE switches report end positions.
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 ACEJ32X100-20SB FAQ
Push is 402.1 N and pull is 345.6 N at 0.5 MPa; at 0.7 MPa push reaches 563 N and pull 483.8 N, with a theoretical maximum of 82 kgf at 1.0 MPa. The -20 code sets a 20 mm adjustment window: an external stop screw shortens the 100 mm extend stroke by up to 20 mm, so the working range is 80-100 mm. It trims the stroke only; it never lengthens it past 100 mm.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and FA flange or LB foot brackets bolt straight to its face. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be slid into the body slots for end-position sensing. A fixed TPU bumper at each end absorbs end-of-stroke energy; it is not a load-holding brake.
