Airtac ATE Single Acting Guided Compact Cylinder ATE32X20
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE32X20 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 ATE32X20
This AirTAC ATE32X20 is a single acting pull cylinder with a spring return, meaning the spring extends the rod and air retracts it. With a 32 mm bore, it delivers a net pull of 296 N at 0.5 MPa and 434.2 N at 0.7 MPa, so you can plan for about 18 kg of safe vertical lifting at 0.5 MPa with a 2:1 margin. The ISO 21287 short body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which helps it fit into tight jigs and guards where a full-length unit will not. The hard-anodized aluminium body and S45C hard-chrome rod resist wear, and the fixed TPU bumper at both ends absorbs end-of-stroke energy without needing adjustment.
This model has no magnet fitted, so it cannot accept CMSE or DMSE sensors unless you order the optional -S code. The port is 1/8" PT, and the female rod thread is M8x1.25, so it mounts directly to standard ISO 21287 fixtures. Operating pressure is 0.2-1.0 MPa (28-145 psi), and the speed range is 50-500 mm/s, making it a reliable choice for short-stroke pull applications.

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 ATE32X20 Is Used
Jig Clamping
Use the ATE32X20 to pull a clamp arm down onto a workpiece in a CNC fixture, with 296 N at 0.5 MPa holding parts securely during light machining.
Gate Positioning
Mount this cylinder on a small conveyor line to retract a stop gate, pulling it down to let a box pass, then the spring extends it back up to block the next item.
Pneumatic Test Rig
In a lab test setup, use the ATE32X20 to pull a sensor probe away from a test piece after measurement, with the spring returning it to the ready position automatically.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE32X20 the Right Cylinder?
For a 32 mm bore, the ATE32X20 provides 296 N of pull at 0.5 MPa, which suits light clamping or indexing tasks. If you need more force, consider the ATE40X25 with 500.3 N at 0.5 MPa, or step down to the ATE25X25 with 170.9 N for smaller loads. This cylinder is spring-extend, so it returns to the extended position on air loss and does not hold a mid-stroke position. Choose the optional -S code if you need a magnet for CMSE or DMSE sensors, and select from FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, or FTC mounts to match your fixture.
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 ATE32X20 FAQ
The ATE32X20 delivers a net pull of 296 N at 0.5 MPa and 434.2 N at 0.7 MPa, with these values already accounting for the return spring. The minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi). The operating pressure range is 0.2-1.0 MPa (28-145 psi), and the speed range is 50-500 mm/s.
The ATE32X20 has a short body that saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits into tight spaces on jigs, guards, and gantries. It uses a fixed TPU bumper at both ends to absorb end-of-stroke impact, and the optional -S magnet enables CMSE or DMSE sensors for position detection.
