About the Airtac ATE Single Acting Guided Compact Cylinder ATE20X20SB
This AirTAC ATE20X20SB is a single acting pull cylinder, spring-return, so the spring extends the rod and air retracts it. With a 20 mm bore, it delivers 88.1 N of pull at 0.5 MPa, net of the return spring, making it a compact force source for light automation tasks.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, fitting into tight machine guards and gantries. The optional -S magnet is fitted here, enabling CMSE or DMSE switches for position sensing. For a real load, plan for about 53 N of work at 0.5 MPa, which lifts roughly 5.4 kg vertically with a 2:1 safety 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 (Ø20mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 88.1 N |
| 0.7 MPa | 135.2 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 ATE20X20SB Is Used
Jig Clamping
Use in a small fixture to pull a clamp arm onto a workpiece, with the spring extending to release. The 88.1 N pull at 0.5 MPa secures light parts in a CNC or assembly jig.
Label Applicator
Retract a label tamp head in a packaging line, pulling it back after applying a label to a box. The compact body fits between guide rails, and the spring returns the head for the next cycle.
Guard Interlock
Pull a safety latch on a machine guard, with the spring extending to lock the guard when air is off. The 20 mm stroke and M5x0.8 port suit small pneumatic control panels.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE20X20SB the Right Cylinder?
For a lighter pull, consider the ATE16X25 with 53.3 N at 0.5 MPa, while the ATE25X25 offers 170.9 N for heavier tasks. This ATE20X20SB with a 20 mm stroke suits short-stroke applications; it does not hold a mid-stroke position on air loss, as the spring returns the rod to its extended home. The male rod thread (B code) and M5x0.8 port simplify mounting, and the optional magnet is already included for sensor feedback.
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 ATE20X20SB FAQ
The ATE20X20SB provides a pull force of 88.1 N at 0.5 MPa and 135.2 N at 0.7 MPa, both net of the return spring. Minimum working pressure is 0.2 MPa, and proof pressure is 1.5 MPa (215 psi).
The ISO 21287 short body is about 50% shorter than an ISO 15552 profile cylinder, saving mounting space in tight fixtures. It includes a fixed TPU bumper at both ends to absorb end-of-stroke energy, and the optional -S magnet allows CMSE or DMSE switch mounting.
