Airtac ATE Single Acting Guided Compact Cylinder ATE20X15B
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE20X15B is a genuine single acting, pull (spring return) ISO 21287 compact air cylinder with a Ø20mm bore and 15mm stroke, M5×0.8 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 ATE20X15B
This AirTAC ATE20X15B is a single acting pull cylinder, spring-return type, so the spring extends the rod and air retracts it. With a 20 mm bore, it delivers 88.1 N of pull at 0.5 MPa, net of the return spring, making it a compact force source for light assembly tasks.
Its ISO 21287 short body takes about 50% less mounting length than an ISO 15552 profile cylinder, so it fits into tight machine guards and gantries. The hard-anodized aluminium body and S45C hard-chrome rod resist wear, while the fixed TPU bumper at both ends absorbs end-of-stroke impact. At 0.5 MPa, a safe working load is about 53 N, or roughly 5.4 kg vertically with a 2:1 margin, helping you match real part weights without oversizing.

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 (Ø20mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 88.1 N |
| 0.7 MPa | 135.2 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 ATE20X15B Is Used
Jig Clamping on CNC Fixtures
Use the 88.1 N pull to retract a spring-loaded clamp pin in a CNC fixture, freeing a part for quick changeover. The compact body fits under the workholding plate without protruding into the machining envelope.
Carton Tabbing in Packaging Lines
Drive a tab-folding finger that pulls a carton flap into place before sealing. The 15 mm stroke and 5.4 kg vertical lift capacity handle lightweight cardboard without crushing it, and the fixed bumper prevents flap bounce.
Safety Gate Latch on Small Presses
Retract a latch bolt that holds a safety guard closed on a benchtop press. The spring extends the bolt to lock the guard when air is off, meeting fail-safe needs, while the short body mounts inside the guard frame.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE20X15B the Right Cylinder?
For lighter pulls, the ATE16X25 offers 53.3 N at 0.5 MPa, while the ATE25X25 steps up to 170.9 N, so you can scale force with bore size. This ATE20X15B has a male rod thread (B code) and a PT port, and its 15 mm stroke suits short pick-and-place motions. Remember, on air loss the spring returns the rod to its extended home position, so it does not hold a mid-stroke load; choose a double-acting ACE model if you need powered return and position control.
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 ATE20X15B FAQ
The ATE20X15B delivers 88.1 N at 0.5 MPa and 135.2 N at 0.7 MPa, both net of the return spring. It operates from 0.2 MPa minimum pressure up to 1.0 MPa (28-145 psi), with a proof pressure of 1.5 MPa (215 psi). The fixed TPU bumper handles end-of-stroke impact, and the speed range is 50-500 mm/s.
Yes, the ATE20X15B is an ISO 21287 compact cylinder, so its body is about 50% shorter than an ISO 15552 profile cylinder of the same bore. It has a hard-anodized aluminium body and a male rod thread (B code). This model has no magnet, so it cannot accept CMSE or DMSE sensors; order the -S version if you need position sensing.
