Airtac ATE Single Acting Guided Compact Cylinder ATE50X15S
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE50X15S is a genuine single acting, pull (spring return) ISO 21287 compact air cylinder with a Ø50mm bore and 15mm 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 ATE50X15S
This ATE50X15S is a single acting pull cylinder, meaning its spring extends the rod and air retracts it, with forces already net of the spring. At 0.5 MPa it delivers 775 N of pull, so it can handle a safe working load of about 465 N (47 kg) when you apply a 0.6 factor for real-world duty.
Its ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, saving valuable space in tight fixtures. The optional -S magnet is fitted here, enabling CMSE or DMSE switches for position sensing, and the hard-anodized aluminium body with a hard-chrome S45C rod resists wear in daily service.

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 ATE50X15S Is Used
Jig Clamping
Use the 775 N pull at 0.5 MPa to retract a clamping arm in a CNC fixture, holding parts securely during machining. The compact body fits under a worktable where a longer cylinder would not.
Sorting Gate
In a packaging line, this cylinder pulls a diverter gate to route products to different lanes. The spring extends the gate when air is off, keeping the default path clear, and the 15 mm stroke is enough for small cartons.
Test Probe Retraction
On an automated test station, retract a sensor probe with 775 N to clear the part after inspection. The fixed TPU bumper at both ends absorbs the stop, and the -S magnet lets you confirm probe position with a DMSE switch.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE50X15S the Right Cylinder?
For lighter pull tasks, consider the ATE40X25S with 500 N at 0.5 MPa, while the ATE63X25S offers 1320 N for heavier loads. This 50 mm bore with 15 mm stroke suits applications needing moderate force in a compact envelope, but remember it does not hold a mid-stroke position on air loss - the spring returns it to extended. Mounting options include FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, and FTC brackets, and the optional magnet is already included for sensor integration.
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 ATE50X15S FAQ
At 0.5 MPa, the pull force is 775 N, and at 0.7 MPa it rises to 1127.5 N, both net of the return spring. The minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi).
The body is about 50% shorter than an ISO 15552 profile cylinder, so it fits in tight spaces like guard enclosures or gantries. It uses a fixed TPU bumper at both ends to absorb end-of-stroke energy, and the optional -S magnet allows CMSE or DMSE switches for position feedback.
