Airtac ATE Single Acting Guided Compact Cylinder ATE32X20B
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE32X20B is a genuine single acting, pull (spring return) ISO 21287 compact air cylinder with a Ø32mm bore and 20mm 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 ATE32X20B
This AirTAC ATE32X20B is a single acting, spring-extend compact cylinder that pulls on air pressure, delivering a net pull of 296 N at 0.5 MPa and 434.2 N at 0.7 MPa. Its ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, fitting into tight machine frames and guarding where a full-length unit won't go.
The hard-anodized aluminium body and S45C hard-chrome rod resist wear in repetitive cycles, while the fixed TPU bumper at both ends absorbs end-of-stroke impact. With a male rod thread (B code) and PT port, this unit is ready for direct linkage. For a real-world load, plan on about 18 kg of safe vertical work at 0.5 MPa, a practical margin below the full rating.

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 ATE32X20B Is Used
Jig Clamping
Pull a locating pin or clamp arm in a CNC fixture, using the 296 N pull to secure a part during drilling or milling. The compact body fits under the worktable, and the spring extends the pin when air is released.
Gate Divider
Retract a stop or diverter on a packaging conveyor to route products into separate lanes. The 20 mm stroke and 434.2 N pull at 0.7 MPa handle light cartons, while the TPU bumper quiets the end of each cycle.
Guard Lock
Pull a safety interlock bolt on a machine access door, releasing it when air is applied. The spring extends the bolt to lock the guard when air pressure drops, providing a fail-safe position without a separate brake.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE32X20B the Right Cylinder?
For a lighter pull, the ATE25X20 offers 170.9 N at 0.5 MPa, while stepping up to the ATE40X20 gives 500.3 N at the same pressure. This 32 mm bore unit suits short-stroke pull applications up to 25 mm standard, with a minimum working pressure of 0.2 MPa to overcome the return spring. The spring extends the rod at rest and on air loss, so it does not hold a mid-stroke position. Mounting options include FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, and FTC brackets, all compatible with the ISO 21287 face. Note that this model has no magnet, so sensor mounting is not possible; choose the -S option for CMSE or 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 ATE Single Acting Guided Compact Cylinder ATE32X20B FAQ
The ATE32X20B 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. It operates from 0.2 to 1.0 MPa (28-145 psi) and has a proof pressure of 1.5 MPa (215 psi). Speed range is 50-500 mm/s, and the port is 1/8".
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits into tight jigs and gantries. The fixed TPU bumper at both ends absorbs end-of-stroke energy, and the hard-anodized aluminium body resists wear. This model has a male rod thread and no magnet; order the -S option to enable CMSE or DMSE sensors.
