Airtac ATE Single Acting Guided Compact Cylinder ATE100X25S
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE100X25S 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 ATE100X25S
This AirTAC ATE100X25S is a single acting pull cylinder with spring return, meaning the spring extends the rod and air retracts it. With a 100 mm bore, it delivers a net pull of 3483.6 N at 0.5 MPa and 4991.6 N at 0.7 MPa, already accounting for the spring force, so you can size your tooling directly from these numbers.
The ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, freeing space in tight gantries and guarding. The optional -S magnet is fitted here, enabling CMSE or DMSE switches for position sensing. As a buyer insight, at 0.5 MPa this unit can safely handle about 213 kg of vertical load (3483.6 N x 0.6 / 9.81), so plan your real workload with that margin in mind.

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 ATE100X25S Is Used
Heavy Clamp Retraction
In a CNC fixture, retract a heavy swing clamp that must pull a workpiece tight against a stop. The 3483.6 N pull at 0.5 MPa handles large parts, while the compact body fits under a low machine guard.
Pallet Stop Release
On a conveyor line, pull a pallet stop down to let a loaded pallet pass. The 25 mm stroke is enough to clear the stop, and the spring extends it back up automatically when air is removed, keeping the line safe.
Die Cushion Retract
In a stamping press, retract a die cushion pad after each stroke. The 100 mm bore provides the force to overcome die springs, and the fixed TPU bumper absorbs the end-of-stroke impact without adjustment.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE100X25S the Right Cylinder?
Choose this ATE100X25S when you need a powerful pull action in a short envelope, such as clamping or retracting a heavy guard. For lighter duties, consider the ATE80X25S with 2159.1 N pull at 0.5 MPa, or step down to the ATE63X25S at 1320.0 N if space is even tighter. Remember, the spring returns the rod to extended on air loss, so it will not hold a mid-stroke position; use it for end-to-end motion only. The 1/4" port suits standard shop air, and the optional -S magnet allows CMSE or DMSE switch mounting for position feedback.
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 ATE100X25S FAQ
At 0.5 MPa, the pull force is 3483.6 N; at 0.7 MPa, it is 4991.6 N. These are net of the return spring, so they are the usable forces. The minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi). The operating pressure range is 0.2-1.0 MPa (28-145 psi).
The ISO 21287 body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight spaces like machine guards or gantries. It uses a fixed TPU bumper at both ends to absorb end-of-stroke energy, which is not adjustable but requires no maintenance. The optional -S magnet is fitted on this model, allowing CMSE or DMSE switches for position sensing.
