Airtac ATE Single Acting Guided Compact Cylinder ATE50X20B
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE50X20B 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 ATE50X20B
This ATE50X20B is a single acting pull cylinder with a spring that extends the rod and air that retracts it, delivering 775 N of pull at 0.5 MPa. Its ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, fitting into tight machine guards and gantries where full-length cylinders cannot go.
The 50 mm bore unit has a 16 mm hard-chrome plated S45C rod and a 1/8" port, with a fixed TPU bumper at both ends to absorb impact. At 0.5 MPa, this cylinder can safely lift about 47 kg vertically with a 2:1 safety margin, making it practical for light lifting tasks. The male rod thread (B code) simplifies attachment of custom tooling without needing a rod-end adapter.

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 ATE50X20B Is Used
Jig Retraction
In a CNC machining center, this ATE50X20B pulls a locating pin out of a fixture after clamping, using its 775 N pull to overcome the pin's return spring. The compact body fits between the fixture base and the machine table where a longer cylinder would interfere with chip removal.
Sorting Gate Pull
On a parcel sorting conveyor, this cylinder retracts a diverting gate to let packages pass straight through. The 20 mm stroke is enough to clear the gate from the package path, and the spring extends it back into place when air is released, defaulting to the divert position.
Clamp Release
In an automated assembly station, this unit pulls a spring-loaded clamp open to release a finished part. With 1127.5 N at 0.7 MPa, it reliably overcomes the clamp's spring force, and the fixed TPU bumper prevents shock when the rod reaches the end of its travel.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE50X20B the Right Cylinder?
For lighter pull applications, consider the ATE40X25 with 500 N at 0.5 MPa, while the ATE63X25 offers 1320 N for heavier work. This ATE50X20B sits between them, providing 775 N of pull force net of the spring, which is suitable for medium-duty retraction tasks. The spring extends the rod at rest, so it does not hold a mid-stroke position; plan for full extension when air is off. Mounting options include FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, and FTC brackets that bolt directly to the ISO 21287 face. This model has no magnet, so CMSE or DMSE sensors cannot be fitted; order the -S code if you need position sensing.
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 ATE50X20B FAQ
The ATE50X20B is a single acting pull cylinder with spring extend. Its net pull force is 775 N at 0.5 MPa and 1127.5 N at 0.7 MPa, already accounting for the return spring. The minimum working pressure is 0.2 MPa, operating range is 0.2-1.0 MPa (28-145 psi), and proof pressure is 1.5 MPa (215 psi). Speed range is 50-500 mm/s, and the port size is 1/8".
The ATE50X20B uses an ISO 21287 compact body that is about 50% shorter than an ISO 15552 profile cylinder, saving mounting space in tight machinery. The hard-anodized aluminium body and S45C hard-chrome rod provide durability. A fixed TPU bumper at each end absorbs end-of-stroke energy. This model has a male rod thread and no magnet, so order the -S option if you need to mount CMSE or DMSE sensors.
