Airtac ATE Single Acting Guided Compact Cylinder ATE50X20
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE50X20 is a genuine single acting, pull (spring return) ISO 21287 compact air cylinder with a Ø50mm 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 ATE50X20
This ATE50X20 is a single acting pull cylinder with spring return, meaning the spring extends the rod and air retracts it. At 0.5 MPa it delivers 775 N of pull force, net of the spring, so you can plan real work around that figure.
Its ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, which lets it fit into tight gantries and machine guards where a full-length cylinder would not. The optional -S magnet is not fitted here, so no sensor can be mounted unless you order the -S code; the fixed TPU bumper at both ends absorbs end-of-stroke energy without adjustment.

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 (Ø50mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 775.0 N |
| 0.7 MPa | 1127.5 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).

ACE-family variants: ACE (double acting), ASE / ATE (single acting push / pull), ACED (double rod), ACEJ (adjustable stroke), TACE / TACED (non-rotating twin-guide yoke). Mounting accessories: FA / FB flange, LB foot, CA / CB clevis, CR, SDB pivot, FTC; plus I and Y knuckles. Thread PT (blank) / G.
Where the Airtac ATE Single Acting Guided Compact Cylinder ATE50X20 Is Used
Jig clamping
Use the 775 N pull to retract a clamp arm in a CNC fixture, freeing the operator's hands for part loading and unloading.
Sorting gate
Pull a diverter gate in a small parts sorter; the 20 mm stroke is enough to redirect items on a narrow conveyor without taking up much space.
Press guard interlock
Retract a safety guard pin on a bench press; the spring extends the pin to block operation when air is off, meeting a simple safety function.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE50X20 the Right Cylinder?
For a lighter pull, consider the ATE40X25 with 500.3 N at 0.5 MPa, or step up to the ATE63X25 for 1320 N. Since this is a spring-extend cylinder, it returns to the extended position on air loss and 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.
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 ATE50X20 FAQ
At 0.5 MPa the pull is 775 N, and at 0.7 MPa it is 1127.5 N, both net of the return spring. Minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi).
No, this model has no magnet, so a sensor cannot be mounted. To use CMSE or DMSE switches, you must order the -S code, which adds the optional magnet.
