About the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE100X25B
The ASE100X25B is a single acting push cylinder with spring return: air extends the 20 mm rod and the internal spring retracts it, so one air line is all the machine needs. This is the largest bore in AirTAC's ISO 21287 compact family - a 100 mm piston delivering 3640.7 N of push at 0.5 MPa (5211.5 N at 0.7 MPa), both figures already net of the return spring. The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits heavy clamping inside tight press fixtures and guarding.
In practice, plan on roughly 2184 N of usable push at 0.5 MPa (about 60% of rating), which corresponds to lifting about 185 kg vertically with a 2:1 margin. The hard-anodized aluminium body carries a roller-burnished bore, the S45C rod is hard-chrome plated, and a fixed TPU bumper at each end absorbs end-of-stroke shock. Minimum working pressure is 0.2 MPa to overcome the spring, with a 0.2-1.0 MPa (28-145 psi) operating band, 50-500 mm/s speed and a 1/4" PT port.

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 (Ø100mm)
| Pressure | Push force (spring return) |
|---|---|
| 0.5 MPa | 3640.7 N |
| 0.7 MPa | 5211.5 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 ASE100X25B Is Used
Press-fit clamping of bearing housings
The 3640.7 N push at 0.5 MPa seats automotive bearing housings into housings on a 25 mm short stroke, with the spring retracting the tool automatically between cycles.
Gate locking on heavy machine guards
Air extends the plunger to lock a CNC enclosure gate; on air loss the spring pulls it home, and the compact body fits inside the guard's narrow frame extrusion.
Case squaring on palletizing lines
A 100 mm bore square pushes misaligned cartons flush at up to 500 mm/s, with the fixed TPU bumpers absorbing the stop at each end of the 25 mm stroke.
Is the Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE100X25B the Right Cylinder?
At 3640.7 N push (0.5 MPa) this 100 mm bore is the top of the range - step down to ASE80X25B (2316.2 N) for lighter clamps or up from ASE63X25B (1420.5 N) if 63 mm falls short. The B code gives a male 20 mm rod thread (M12x1.75 female on the plain version) with a PT port thread; order G instead for BSPP plumbing. Strokes run short by design - 25 mm standard for this bore - and the spring returns the rod home on air loss rather than holding a mid-stroke position. FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot or FTC mounting bolts straight to the ISO 21287 face, and add the -S code if you need the optional 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 ASE100X25B FAQ
It is single acting push with spring return, so the quoted forces are already net of the spring: 3640.7 N at 0.5 MPa and 5211.5 N at 0.7 MPa. At least 0.2 MPa is needed to beat the return spring. Operating range is 0.2-1.0 MPa (28-145 psi), proof pressure 1.5 MPa (215 psi), speed 50-500 mm/s, air filtered to 40 um, and the port is 1/4" PT with a male rod thread (B code).
The ISO 21287 compact body is hard-anodized aluminium with an S45C hard-chrome rod and a fixed TPU bumper at each end that decelerates the piston at stroke ends. The magnet is not fitted on this code - order the optional -S version to enable CMSE / DMSE switches for end-of-stroke sensing. FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot and FTC brackets mount directly to the standard face.
