Airtac ATE Single Acting Guided Compact Cylinder ATE50X20SB
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE50X20SB 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 ATE50X20SB
This AirTAC ATE50X20SB is a single acting pull cylinder with a spring that extends the rod and air that retracts it, delivering a net pull of 775 N at 0.5 MPa. Its ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, letting it fit into tight machine guards and gantries where a full-length unit would not.
The hard-anodized aluminium body and S45C hard-chrome rod resist wear in continuous cycling, while the fixed TPU bumper absorbs end-of-stroke impact. With the optional -S magnet fitted, you can mount CMSE or DMSE switches for position sensing. For a 2:1 safety margin, this cylinder lifts about 39 kg vertically at 0.5 MPa, so plan real work loads around that figure rather than 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 (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).

Where the Airtac ATE Single Acting Guided Compact Cylinder ATE50X20SB Is Used
Jig Retraction
Pull a locating pin back from a workpiece on a CNC fixture, using the 775 N net force at 0.5 MPa to overcome friction and the compact body to fit under the table.
Gate Release
Retract a stop gate on a packaging conveyor to let a carton pass, with the 20 mm stroke clearing the path and the TPU bumper handling rapid cycling.
Guard Latch
Pull a safety interlock latch on a machine guard, where the spring-extend fail-safe returns the latch to the locked position when air is removed.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE50X20SB the Right Cylinder?
Choose this 50 mm bore when you need a compact pull action with a net 775 N at 0.5 MPa, such as retracting a clamp or a light gate. If your load is lighter, the 40 mm bore offers 500 N at 0.5 MPa, while the 63 mm bore steps up to 1320 N for heavier pulls. The 20 mm stroke suits short indexing moves, and the male rod thread (B) simplifies attachment to clevises or rod knuckles. Remember, the spring returns the rod to extended on air loss, so it does not hold a mid-stroke position.
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 ATE50X20SB FAQ
At 0.5 MPa, the net pull force is 775 N, and at 0.7 MPa it is 1127.5 N. These values already account for the return spring, so they are the usable pull forces. The minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa.
The short body saves about 50% of the mounting length compared to an ISO 15552 profile cylinder, so it fits into tight spaces like gantries or inside machine frames. The fixed TPU bumper at both ends absorbs end-of-stroke energy, and the optional -S magnet allows CMSE or DMSE switches for position sensing.
