Airtac ATE Single Acting Guided Compact Cylinder ATE40X25S
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE40X25S is a genuine single acting, pull (spring return) ISO 21287 compact air cylinder with a Ø40mm bore and 25mm 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 ATE40X25S
This AirTAC ATE40X25S is a single acting pull cylinder with spring return, built to the ISO 21287 compact standard. Its hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder, freeing space in tight machine frames and guarding. The S45C hard-chrome rod retracts with 500.3 N at 0.5 MPa, net of the return spring, and the fixed TPU bumper absorbs end-of-stroke impact.
The optional -S magnet is fitted on this model, so CMSE or DMSE reed and solid-state switches can mount directly in the body slots for position sensing. For a real-world check, the 500.3 N pull at 0.5 MPa translates to about 51 kg of theoretical lift; with a 2:1 safety margin, plan for roughly 25 kg of vertical work. The 1/8" port keeps installation simple, and the spring extends the rod automatically when air pressure drops below 0.2 MPa.

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 (Ø40mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 500.3 N |
| 0.7 MPa | 729.0 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 ATE40X25S Is Used
Jig Clamp Retract
Use the 500.3 N pull at 0.5 MPa to retract a locating pin in a CNC fixture. The compact ISO 21287 body fits under the worktable, and the spring extends the pin when the cycle ends.
Gate Divider
Mount this cylinder on a packaging conveyor to pull a diverting gate open. The 25 mm stroke clears the product path, and the optional -S magnet lets a DMSE switch confirm the gate is fully retracted.
Safety Guard Latch
In a press cell, the ATE40X25S pulls a guard latch free before the door opens. The spring extends the latch on air failure, keeping the guard closed, and the fixed TPU bumper prevents shock at the end of travel.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE40X25S the Right Cylinder?
Choose the ATE40X25S when you need a compact pull action with a 25 mm stroke and a 500.3 N pull at 0.5 MPa. If your fixture needs less force, the ATE32X25 delivers 296.0 N at 0.5 MPa; for heavier retracts, step up to the ATE50X25 with 775.0 N at the same pressure. This model carries the -S magnet, so order CMSE or DMSE switches separately to detect rod position. The spring returns the rod to its extended home position on air loss, but it does not hold a mid-stroke load. Mounting options include FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, and FTC brackets, plus I and Y rod knuckles.
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 ATE40X25S FAQ
The ATE40X25S delivers a pull force of 500.3 N at 0.5 MPa and 729 N at 0.7 MPa, both net of the return spring. The minimum working pressure is 0.2 MPa, operating range is 0.2-1.0 MPa (28-145 psi), and proof pressure is 1.5 MPa (215 psi).
The hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder, so it fits in machine guards and gantries where a full-length cylinder will not. The fixed TPU bumper absorbs end-of-stroke energy, and the optional -S magnet on this model allows CMSE or DMSE switches to be mounted for position feedback.
