Airtac ATE Single Acting Guided Compact Cylinder ATE32X5SB
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE32X5SB is a genuine single acting, pull (spring return) ISO 21287 compact air cylinder with a Ø32mm bore and 5mm stroke, 1/8" 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 ATE32X5SB
The ATE32X5SB is a single acting, spring-extend pull cylinder built to the ISO 21287 compact format. A 32 mm bore delivers 296 N of pull at 0.5 MPa (434.2 N at 0.7 MPa), both figures already net of the return spring, and only 0.2 MPa (28 psi) of air is needed to overcome the spring and retract the rod. The S code in this model means the optional -S magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clipped onto the body to report the retracted position.
Because the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, it slots into tight clamping nests and gauge heads where a full-length body will not fit. The hard-anodized aluminium barrel carries a hard-chrome plated S45C rod with a male thread (the B code), and a fixed TPU bumper at each end absorbs end-of-stroke shock. In practice the 296 N pull supports roughly 178 N (about 18 kg) of real work at 0.5 MPa, and with a 2:1 margin it lifts about 15 kg vertically.

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 ATE32X5SB Is Used
Fixture release pin
Spring keeps a locating pin extended in a CNC jig; 296 N of pull at 0.5 MPa retracts it 5 mm so the operator can load a machined housing.
Packaging gate kicker
On a carton line, the normally-extended paddle diverts boxes; a 3-way valve applies air to pull it clear for 5 mm of pass-through travel.
Sample probe retraction
In a lab autosampler, the spring-extended probe sits in the stream; air pulls it back 5 mm between cycles, with a DMSE switch confirming the parked state.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE32X5SB the Right Cylinder?
At 5 mm stroke this is a micro-retraction actuator: the spring holds the rod out and air pulls it back a short distance for ejection, gating or release duties. If 296 N at 0.5 MPa is more than you need, the ATE25X5S gives 170.9 N in the same compact envelope; if you need roughly 70% more muscle, step up to the ATE40X5SB for 500.3 N. Remember that on air loss the spring returns the rod to its extended home position and no mid-stroke position is held. The ISO 21287 mounting face accepts FA/FB flanges, LB feet, CA/CB clevises, CR, SDB pivot and FTC brackets plus I/Y rod knuckles, and the fitted -S magnet lets you add CMSE / DMSE switches without reordering.
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 ATE32X5SB FAQ
This single acting pull cylinder gives 296 N at 0.5 MPa and 434.2 N at 0.7 MPa, both net of the return spring, from a 32 mm bore with a 5 mm stroke. Working pressure is 0.2-1.0 MPa (28-145 psi) with 1.5 MPa (215 psi) proof, air filtered to 40 um, speed 50-500 mm/s, and temperature -20 to +70 C. The spring extends the rod; air retracts it, so the unit fails to the extended position.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium barrel, S45C hard-chrome rod with male thread, and fixed TPU bumpers at both ends that only decelerate the stroke ends. Because this model carries the -S magnet, CMSE or DMSE reed and solid-state switches mount directly on the body slots; models ordered without the S code have no magnet.
