Airtac ATE Single Acting Guided Compact Cylinder ATE16X25SB
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE16X25SB is a genuine single acting, pull (spring return) ISO 21287 compact air cylinder with a Ø16mm bore and 25mm 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 ATE16X25SB
This is a single acting pull cylinder from AirTAC's ISO 21287 compact range: an internal spring extends the 8 mm rod and compressed air retracts it, so the ATE16X25SB sits normally extended and fails to the extended position when air is lost. Pull force is 53.3 N at 0.5 MPa (83.5 N at 0.7 MPa), already net of the spring, and the spring only gives way once supply reaches 0.2 MPa. The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into slim test fixtures and small gate assemblies a full-length body cannot enter.
Practical sizing: treat roughly 32 N (about 3.3 kg of pull work) as the realistic working force at 0.5 MPa instead of the full 53.3 N rating. For vertical retraction duty that translates to lifting roughly 2.7 kg with a 2:1 margin, enough for small covers, chutes and sensor flags. The hard-anodized aluminium body carries a roller-burnished bore, the S45C rod is hard-chrome plated, and fixed TPU bumpers absorb end-of-stroke shock at both ends.

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 (Ø16mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 53.3 N |
| 0.7 MPa | 83.5 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 ATE16X25SB Is Used
Lab slide gate retraction
The 53.3 N pull at 0.5 MPa retracts a small acrylic guard slide on a benchtop test rig, and the spring pushes it closed the moment air drops.
Flag sensor actuation
With the fitted magnet and a DMSE switch, the 25 mm stroke trips a position flag on a packaging counting head, confirming retraction at 0.2 MPa minimum.
Fixture latch release
The normally-extended rod holds a small jig latch closed; applying air pulls it open, and the compact body fits inside the fixture plate where an ISO 15552 profile cylinder would overhang.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE16X25SB the Right Cylinder?
At bore 16 the ATE16X25SB delivers 53.3 N of spring-netted pull at 0.5 MPa. If your load needs more, step up to the ATE20X25 (88.1 N pull at 0.5 MPa) or the ATE25X25 (170.9 N); if less, the ATE12X10 (25.9 N) covers it. Keep strokes short: this single acting pull design tops out at 25 mm standard travel for bore 16, and the spring cannot hold a mid-stroke position. The B code gives a male rod thread with a PT port, and because the S magnet is fitted you can bolt on CMSE or DMSE switches for end-of-stroke signalling. FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot and FTC brackets plus I/Y rod knuckles mount directly on the ISO 21287 face.
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 ATE16X25SB FAQ
Pull force is 53.3 N at 0.5 MPa and 83.5 N at 0.7 MPa, both net of the return spring. It is a single acting pull cylinder: the spring extends the 8 mm rod, air retracts it, and at least 0.2 MPa is needed to move against the spring. Operating range is 0.2-1.0 MPa (28-145 psi), proof 1.5 MPa (215 psi), speed 50-500 mm/s, temperature -20 to +70 C, air filtered to 40 um, port M5x0.8, male rod thread (B code) with PT port thread.
The ISO 21287 body is a hard-anodized aluminium tube with threaded aluminium covers, cutting mounting length by roughly half versus an ISO 15552 profile cylinder. Fixed TPU bumpers at each end absorb end-of-stroke impact. The S in the model code means the optional magnet is fitted on this unit, so CMSE or DMSE reed or solid-state switches can be clamped into the body slots; models without the -S code carry no magnet.
