About the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-50S
The ACEJ32X100-50S 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. The -50 code means an external stop screw trims the 100 mm stroke by up to 50 mm on site, giving a usable extend range of 50-100 mm without changing the cylinder.
The hard-anodized aluminium body with an S45C hard-chrome rod saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding. Because the magnet is fitted (the -S option), CMSE or DMSE reed and solid-state switches mount directly in the body slots. At 0.5 MPa, plan on roughly 240 N (about 24 kgf) of usable push force, which lifts about 12 kg vertically with a 2:1 margin.

Specifications follow the official AirTAC ACE-series (ISO 21287) datasheet. Body: hard-anodized aluminium alloy; piston rod: S45C carbon steel with hard-chrome plating. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G. A built-in magnet is OPTIONAL — add the -S code to fit CMSE / DMSE position sensors.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-50S Is Used
Fixture clamping on CNC machining centers
The 50-100 mm trim range lets one cylinder serve multiple fixture heights, with 402.1 N push clamping aluminum housings securely at 0.5 MPa.
Product stopper gates on packaging lines
The compact body fits under low conveyor frames where an ISO 15552 profile cylinder would not, and the fitted magnet signals gate position via CMSE switches.
Sample press in laboratory automation
About 24 kgf of usable push at 0.5 MPa presses vials or test plates gently, while the 30-500 mm/s speed band matches delicate cycle profiles.
Is the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-50S the Right Cylinder?
Size the load first: at 0.5 MPa this bore pushes 402.1 N, so keep real work near 240 N. A 25 mm bore (245.4 N push) suits lighter clamps, while a 40 mm bore (628.3 N push) covers heavier tooling. Remember the stop screw is an end stop only - on air loss the rod still drifts, so add a separate lock if position must hold. FA flange or LB foot mounts bolt to the ISO 21287 face, and the fitted -S magnet accepts CMSE / DMSE switches for end-of-stroke 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 ACEJ32X100-50S FAQ
At 0.5 MPa it pushes 402.1 N and pulls 345.6 N; at 0.7 MPa, 563 N push and 483.8 N pull; 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 to any setting from 50 to 100 mm. It is a mechanical end stop, not a mid-stroke lock - the rod still drifts if air is lost. Operating pressure is 0.15-1.0 MPa (22-145 psi) and speed is 30-500 mm/s.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, ideal for cramped jigs and gantries. A fixed TPU bumper at each end absorbs end-of-stroke impact. This model carries the optional -S magnet, so CMSE or DMSE reed or solid-state switches mount in the body slots. It has a female M8x1.25 rod thread, 1/8" air port, and FA flange or LB foot mounting options.
