About the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ40X200-20
The ACEJ40X200-20 is a double acting AirTAC compact cylinder built to ISO 21287, with a 40 mm bore and a 200 mm stroke that an external stop screw trims by up to 20 mm on site, giving a usable extend range of 180-200 mm. At 0.5 MPa it pushes 628.3 N and pulls 571.8 N; at 0.7 MPa those rise to 879.6 N and 800.5 N, with a theoretical ceiling of 128.1 kgf at 1.0 MPa. Its short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight guards and gantries where a full-length body will not fit.
For real-world sizing, plan on roughly 377 N of usable push at 0.5 MPa (about 60% of the rating), which is the vertical-lift equivalent of lifting around 38 kg with a 2:1 margin. The hard-anodized aluminium body carries a hard-chrome plated S45C rod with a female M8x1.25 thread, and fixed TPU bumpers absorb end-of-stroke energy at both ends. Air supply is 0.15-1.0 MPa (22-145 psi) filtered to 40 um, speed runs 30-500 mm/s, and the 1/8" port depends only on the 40 mm bore. FA flange and LB foot mounts bolt to the standard ISO 21287 face.

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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 572 N |
| 0.7 MPa | 880 N | 800 N |
| Max (@1.0 MPa) | 128 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 ACEJ40X200-20 Is Used
CNC fixture clamping
The 628.3 N push at 0.5 MPa clamps aluminium housings in machining fixtures, and the 20 mm adjustment window lets one cylinder serve several part heights from 180 to 200 mm.
Packaging line pushers
With a 200 mm stroke at 30-500 mm/s, it diverts cartons on conveyor lines, and the compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder under low guards.
Pallet gate lifting
The 571.8 N pull at 0.5 MPa raises light pallet-stop gates on warehouse conveyors; plan on about 38 kg of vertical lift with a 2:1 margin.
Is the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ40X200-20 the Right Cylinder?
Size this 40 mm bore when your load needs 571.8-628.3 N of pull or push at 0.5 MPa. Step down to a 32 mm bore (402.1 N push) for lighter clamping, or up to a 50 mm bore (981.7 N push) if the 200 mm stroke carries heavier tooling. The 200 mm stroke sits exactly at the bore's maximum standard length, so no made-to-order build is needed. Remember the stop screw only shortens the extend stroke within the 20 mm window and is not a mid-stroke lock: on air loss the piston still drifts. Order the -S code if you later need CMSE or DMSE switches; this unit ships without a magnet.
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 ACEJ40X200-20 FAQ
At 0.5 MPa it pushes 628.3 N and pulls 571.8 N; at 0.7 MPa it pushes 879.6 N and pulls 800.5 N, with a theoretical maximum of 128.1 kgf at 1.0 MPa. The -20 code sets a 20 mm adjustment window: an external stop screw shortens the 200 mm extend stroke anywhere in the 180-200 mm range. It is a mechanical end stop only, so on air loss the piston still drifts. Operating pressure is 0.15-1.0 MPa (22-145 psi) and speed is 30-500 mm/s.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body, a hard-chrome plated S45C rod threaded M8x1.25 female, and fixed TPU bumpers at both ends that decelerate the piston at the ends of travel. Mounting options include FA flange and LB foot brackets that bolt to the standard ISO 21287 face. This model has no magnet fitted; order the optional -S version to enable CMSE or DMSE reed or solid-state switches along the body's magnet slots.
