About the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE40X5S
The ASE40X5S is a single acting push, spring-return compact cylinder built to ISO 21287: air extends the 12 mm rod, and the return spring retracts it to the home position. This 40 mm bore, 5 mm stroke version delivers 556.8 N of push at 0.5 MPa (net of the spring) and 808.1 N at 0.7 MPa, with the optional -S magnet fitted so CMSE / DMRE switches can be mounted. Wait - sensors are CMSE / DMSE only. Minimum working pressure is 0.2 MPa (28-145 psi operating range, proof 1.5 MPa (215 psi)).
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight clamping nests and guarded stations. A hard-anodized aluminium body carries a roller-burnished bore, the S45C rod is hard-chrome plated, and a fixed TPU bumper absorbs end-of-stroke energy at both ends. For planning: about 334 N of the 556.8 N rating is a realistic working force at 0.5 MPa, which lifts roughly 28 kg vertically with a 2:1 margin.

Theoretical Output Force (Ø40mm)
| Pressure | Push force (spring return) |
|---|---|
| 0.5 MPa | 556.8 N |
| 0.7 MPa | 808.1 N |
Single-acting push: air extends the rod; the return spring retracts it. Forces already net the spring; minimum working pressure is 0.2 MPa. Single-acting strokes are short (Ø12 to 10 mm, Ø16-100 to 25 mm).

Where the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE40X5S Is Used
Short-travel part clamping
The 5 mm stroke is ideal for a yes/no clamp on a CNC fixture that seats a machined aluminium housing against a stop - 556.8 N at 0.5 MPa holds it firmly, and the spring releases the part the moment air drops.
Eject or kick-off station
Use the push stroke to nudge a small plastic cap off a filling-line nest into a chute. One air line, spring return, and the 50-500 mm/s speed band lets you tune the kick.
Presence check with feedback
Because the -S magnet is fitted, a CMSE or DMSE switch on the body confirms the rod reached the extended position - useful for verifying a lid or connector is fully seated before the next cycle starts.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE40X5S the Right Cylinder?
At 40 mm bore you sit mid-range: a 32 mm bore gives 352.5 N at 0.5 MPa, while a 50 mm bore raises that to 875.5 N. If your clamp needs more than about 334 N of usable force, stay at 40 mm; if the part is lighter, the 32 mm saves space. Remember the spring pulls the rod home on air loss - it will not hold a mid-stroke position. Mount with FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot or FTC brackets; the M8x1.25 female rod thread accepts standard knuckles. 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 0.2 – 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 Single-acting: do not force the rod against the spring.
- check Installation by qualified personnel per AirTAC docs.
Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE40X5S FAQ
Push force is 556.8 N at 0.5 MPa and 808.1 N at 0.7 MPa, both already net of the return spring. Bore 40 mm, stroke 5 mm, rod 12 mm with M8x1.25 female thread, 1/8" PT port. Operating pressure 0.2-1.0 MPa (28-145 psi), proof 1.5 MPa (215 psi), temperature -20 to +70 C, speed 50-500 mm/s, air filtered to 40 um.
The ISO 21287 short body cuts mounting length by roughly half compared with an ISO 15552 profile cylinder, which helps inside guards and gantries. A fixed TPU bumper at each end simply decelerates the piston at the ends of travel - it is not adjustable and never locks or brakes a load. Mounting brackets (FA/FB, LB, CA/CB, CR, SDB, FTC) bolt straight to the ISO 21287 face.
