About the Airtac ATE Single Acting Guided Compact Cylinder ATE32X15S
This ATE32X15S is a single acting pull cylinder from AirTAC, built on the ISO 21287 compact body that trims about 50% of the mounting length of an ISO 15552 profile cylinder. At 0.5 MPa it delivers a net pull of 296 N, and at 0.7 MPa that rises to 434.2 N, with the spring already subtracted from both figures. The bore is 32 mm, the stroke is 15 mm, and the rod is 12 mm with a female M8x1.25 thread. Because this model carries the optional -S magnet, you can fit CMSE or DMSE reed or solid-state switches for position sensing, which is handy for automated cycles where you need to confirm the rod has returned. For a real-world load, plan on about 178 N of usable force at 0.5 MPa, which translates to roughly 18 kg of vertical lift with a 2:1 safety margin, so you can match it against a part weight before you build the fixture.
The body is hard-anodized aluminium alloy, and the S45C carbon-steel rod is hard-chrome plated for wear resistance. The fixed TPU bumper at each end absorbs the impact of the stroke, and the minimum working pressure is 0.2 MPa, with a proof pressure of 1.5 MPa. Air must be filtered to 40 um, and the operating range is 0.2-1.0 MPa (28-145 psi), with speeds from 50 to 500 mm/s. The temperature window is -20 to +70 C, so it suits most factory floor conditions without special treatment.

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 | Pull force (spring return) |
|---|---|
| 0.5 MPa | 296.0 N |
| 0.7 MPa | 434.2 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 ATE32X15S Is Used
Jig Clamping on a CNC Fixture
Use the 296 N pull at 0.5 MPa to retract a locating pin in a CNC workholding jig, where the spring extends the pin to seat the part and air pulls it clear for unloading. The short ISO 21287 body fits under the fixture table, and the optional -S magnet lets a CMSE switch confirm the pin is fully retracted before the next cycle starts.
Gate Stop on a Packaging Line
Mount this cylinder on a conveyor to pull a stop finger down and let a carton pass, with the spring lifting the finger back up to block the next item. The 15 mm stroke is enough to clear a typical package edge, and the 434.2 N pull at 0.7 MPa handles the inertia of a moving box without stalling.
Valve Actuator for a Pneumatic System
In a small automation cell, use the ATE32X15S to pull a spool valve or a flow-control lever back to its home position, relying on the spring to return it when air is vented. The fixed TPU bumper keeps the end-of-stroke impact quiet, and the 1/8" port matches common manifold fittings for quick integration.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE32X15S the Right Cylinder?
When you size this ATE32X15S, compare it against the smaller ATE25X25, which pulls 170.9 N at 0.5 MPa, and the larger ATE40X25, which pulls 500.3 N at the same pressure. For a 15 mm stroke, the 32 mm bore gives you a middle ground between compact size and force, but if your load is under 170 N you could drop to the 25 mm bore and save space, while anything over 500 N would push you to the 40 mm bore. Remember that the spring returns the rod to the extended position when air is off, so it does not hold a mid-stroke position; it simply retracts when you apply pressure. The 1/8" port is standard for this bore, and you can choose FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, or FTC mounting brackets to fit your fixture. Since this unit has the -S magnet, you can add CMSE or DMSE switches, but if you do not need sensing, a non-magnet version would be lighter on cost.
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 ATE32X15S FAQ
The ATE32X15S delivers a net pull of 296 N at 0.5 MPa and 434.2 N at 0.7 MPa, with the spring force already subtracted. The minimum working pressure is 0.2 MPa, and the maximum is 1.0 MPa (145 psi), with a proof pressure of 1.5 MPa. The speed range is 50-500 mm/s, and the operating temperature is -20 to +70 C.
The ISO 21287 compact design saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits in narrow jigs or behind guards where a full-length cylinder would not. The fixed TPU bumper at both ends absorbs the end-of-stroke energy to reduce noise and wear, but it is not adjustable and does not lock or hold a load. The body is hard-anodized aluminium, and the rod is hard-chrome plated S45C steel for durability.
