Airtac ATE Single Acting Guided Compact Cylinder ATE100X25B
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE100X25B is a genuine single acting, pull (spring return) ISO 21287 compact air cylinder with a Ø100mm bore and 25mm stroke, 1/4" 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 ATE100X25B
This AirTAC ATE100X25B is a single acting pull cylinder, spring-extend type, in a compact ISO 21277 body that saves about 50% of the mounting length of an ISO 15552 profile cylinder. With a 100 mm bore, it delivers 3483.6 N of pull at 0.5 MPa, net of the return spring, and 4991.6 N at 0.7 MPa.
At 0.5 MPa, the usable vertical lift is about 213 kg (3483.6 N divided by 9.81, then halved for a 2:1 safety margin), so it can handle substantial parts in a press or lift fixture. The hard-anodized aluminium body and S45C hard-chrome rod resist wear, and the fixed TPU bumper at both ends absorbs end-of-stroke impact without adjustment. Minimum working pressure is 0.2 MPa to overcome the spring.

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 (Ø100mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 3483.6 N |
| 0.7 MPa | 4991.6 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 ATE100X25B Is Used
Press Toggle Pull
In a stamping press, this ATE100X25B retracts a heavy die or slide with 3483.6 N at 0.5 MPa, and the compact body fits under a tight bolster plate where a full-length cylinder would not.
Conveyor Gate Retract
Use it to pull a 200 kg conveyor diverter gate back at 0.5 MPa, relying on the spring to extend the gate into position when air is off, ensuring fail-safe closure.
Fixture Clamp Unlock
In a CNC fixture, this cylinder pulls a clamp arm away from a workpiece with 4991.6 N at 0.7 MPa, and the TPU bumper prevents shock when the arm hits the stop.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE100X25B the Right Cylinder?
For a smaller footprint with lighter loads, consider the ATE80X25 with 2159.1 N pull at 0.5 MPa, while this ATE100X25B offers nearly 62% more force for heavier pulls. The male rod thread (B code) simplifies direct coupling to a load, and the 1/4" port suits larger flow requirements. Since this model has no -S magnet, it cannot mount CMSE or DMSE sensors; order the -S code if you need position sensing. On air loss, the spring returns the rod to its extended home position, so it does not hold a mid-stroke position.
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 ATE100X25B FAQ
At 0.5 MPa, the pull force is 3483.6 N, and at 0.7 MPa it is 4991.6 N, both net of the return spring. The operating pressure range is 0.2-1.0 MPa (28-145 psi), with a proof pressure of 1.5 MPa (215 psi). Speed range is 50-500 mm/s.
No, this model does not have the optional -S magnet, so it cannot mount CMSE or DMSE switches. If you need position sensing, order the -S version (ATE100X25SB) which includes the magnet. The cylinder uses a fixed TPU bumper at both ends, not an adjustable cushion.
