About the Airtac ATE Single Acting Guided Compact Cylinder ATE25X25SB
This AirTAC ATE25X25SB is a single acting pull cylinder with a spring return, meaning the spring extends the rod and air retracts it. It delivers a net pull of 170.9 N at 0.5 MPa and 253.3 N at 0.7 MPa, with a minimum working pressure of 0.2 MPa to overcome the spring.
The ISO 21287 compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder, fitting into tight spaces. With the optional -S magnet, you can mount CMSE or DMSE switches for position sensing. For a safe vertical lift, plan for about 10 kg (170.9 N / 9.81 / 2) with a 2:1 margin.

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 (Ø25mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 170.9 N |
| 0.7 MPa | 253.3 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 ATE25X25SB Is Used
Jig Clamping
Use in a drill jig to pull a clamp arm down onto a workpiece, with the spring returning the arm up when air is released. The compact body fits under the fixture table.
Vertical Gate
Actuate a small safety gate on a packaging line, pulling it down to block access. The 170.9 N pull at 0.5 MPa is enough for a light aluminum guard, and the spring lifts it back up.
Part Ejector
Retract a pin to eject a small plastic part from a mold cavity. With the -S magnet, a DMSE switch confirms the pin is fully retracted before the next cycle starts.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE25X25SB the Right Cylinder?
For a smaller option, the ATE20X25 offers 88.1 N pull at 0.5 MPa, while the ATE32X25 provides 296.0 N. This 25 mm bore suits light clamping or positioning tasks. Remember, the spring returns the rod to extended on air loss, so it does not hold a mid-stroke position. Mounting options include FA/FB flange, LB foot, CA/CB clevis, and more.
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 ATE25X25SB FAQ
At 0.5 MPa, the pull force is 170.9 N, and at 0.7 MPa it is 253.3 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).
Yes, this model includes the optional -S magnet, allowing you to mount CMSE or DMSE reed or solid-state switches. The magnet is not standard on all ATE cylinders; you must order the -S code to get it.
