Airtac ATE Single Acting Guided Compact Cylinder ATE50X15SB
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE50X15SB 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 ATE50X15SB
This AirTAC ATE50X15SB is a single acting pull cylinder with a spring-return mechanism, meaning the spring extends the rod and air retracts it. It delivers a net pull force of 775 N at 0.5 MPa and 1127.5 N at 0.7 MPa, already accounting for the spring resistance.
Its ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, making it ideal for tight spaces. The 50 mm bore version has a 16 mm hard-chrome plated rod and a 1/8" port. With the optional -S magnet fitted, you can add CMSE or DMSE sensors for position detection, and the fixed TPU bumper at both ends absorbs end-of-stroke impact.

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 ATE50X15SB Is Used
Jig Clamping
Use in a CNC fixture to pull a clamp arm down onto a workpiece, delivering 775 N of holding force at 0.5 MPa in a compact envelope that fits under a machine guard.
Parts Ejector
Retract a pin to release a molded plastic part from a die cavity. The spring extends the pin to push the part out, and air pulls it back for the next cycle.
Sorting Gate
Pull a diverter flap across a conveyor track to route packages. The 15 mm stroke and 50 mm bore provide quick, reliable actuation in a tight transfer station.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE50X15SB the Right Cylinder?
When sizing, compare this 50 mm bore with the 40 mm bore (500.3 N pull at 0.5 MPa) for lighter loads, or the 63 mm bore (1320 N pull at 0.5 MPa) for heavier work. The spring returns the rod to its extended position on air loss, but it does not hold a mid-stroke position. This model has a male rod thread (B code) and a PT port, and the -S magnet enables sensor mounting. Mounting options include FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, and FTC brackets.
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 ATE50X15SB FAQ
At 0.5 MPa, the pull force is 775 N, and at 0.7 MPa it is 1127.5 N. These values are 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, saving mounting length in tight fixtures. It has a fixed TPU bumper at both ends to absorb impact, and the optional -S magnet allows you to mount CMSE or DMSE sensors for position feedback.
