Airtac ATE Single Acting Guided Compact Cylinder ATE16X25S
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE16X25S is a genuine single acting, pull (spring return) ISO 21287 compact air cylinder with a Ø16mm bore and 25mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. Its short compact envelope saves about 50% of the mounting length of an ISO 15552 profile cylinder.

About the Airtac ATE Single Acting Guided Compact Cylinder ATE16X25S
This is a single acting pull cylinder: an internal spring extends the 8 mm rod and compressed air retracts it, so the ATE16X25S sits normally extended and returns to that home position on air loss. Net pull force is 53.3 N at 0.5 MPa (83.5 N at 0.7 MPa, already after the spring), with working pressure 0.2-1.0 MPa (28-145 psi) and a 0.2 MPa minimum to overcome the spring. The -S code on this model means the magnet is fitted, so CMSE / DMSE reed or solid-state switches can be clipped onto the body for end-of-stroke signalling.
The body is an ISO 21287 compact build in hard-anodized aluminium, roughly 50% shorter in mounting length than an ISO 15552 profile cylinder, which is why it drops into tight jigs and guarded assemblies where a full-length body will not fit. A fixed TPU bumper at each end absorbs end-of-stroke energy, the S45C rod is hard-chrome plated, and the M5x0.8 port follows the bore. For planning: about 32 N of that 53.3 N is a realistic working figure at 0.5 MPa, and vertically it lifts roughly 2.7 kg 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 (Ø16mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 53.3 N |
| 0.7 MPa | 83.5 N |
Single-acting pull: the spring extends the rod; air 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 ATE Single Acting Guided Compact Cylinder ATE16X25S Is Used
Small-part ejection from machining nests
The spring-extended rod pushes a finished 2-3 kg aluminium bushing out of a CNC nest when air is vented, and the 25 mm stroke clears the part for pick-up.
Position-flagged test fixtures
With the fitted -S magnet, a DMSE switch on the body confirms the retracted state of a spring-return probe in an electronics test jig before the cycle starts.
Carton flap hold-open on a packing line
The spring holds a guide flap open at rest; a 0.5 MPa air pulse pulls it closed (53.3 N net) to release each carton into the sealing station.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE16X25S the Right Cylinder?
At 53.3 N net pull (0.5 MPa) this 16 mm bore suits light retraction tasks such as spring-return clamping of small brackets or clearing a 2-3 kg part from a nest. Step down to the 12 mm bore (25.9 N) for tiny fixtures, or up to 20 mm (88.1 N) when the load creeps past about 32 N of real work. Strokes are short by design; 25 mm is the standard length here. Mount with FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot or FTC brackets plus I/Y rod knuckles, and note the female M4x0.7 rod thread (order the B code for male thread). Because the spring returns the rod, it will not hold a mid-stroke position on air loss - it goes home extended.
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 ATE Single Acting Guided Compact Cylinder ATE16X25S FAQ
Net pull (after the return spring) is 53.3 N at 0.5 MPa and 83.5 N at 0.7 MPa. Operating pressure is 0.2-1.0 MPa (28-145 psi) with 0.2 MPa as the minimum to beat the spring; proof pressure is 1.5 MPa (215 psi). Air must be filtered to 40 um, speed range is 50-500 mm/s, temperature -20 to +70 C, and the port is M5x0.8. The spring extends the rod; air retracts it, so on air loss the rod returns extended and no mid-stroke position is held.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body and threaded covers, saving about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at each end to absorb end-of-stroke energy. This model carries the optional -S magnet, so CMSE or DMSE reed / solid-state switches mount directly in the body slots; models ordered without the -S code have no magnet. Mounting options include FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot and FTC, with I/Y rod knuckles and an M4x0.7 female rod thread.
