About the Airtac ATE Single Acting Guided Compact Cylinder ATE50X25
This ATE50X25 is a single acting pull cylinder with a spring return, meaning the spring extends the rod and air retracts it. With a 50 mm bore, it delivers a net pull of 775 N at 0.5 MPa and 1127.5 N at 0.7 MPa, already accounting for the spring force. The ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight machine frames and guarding where a longer cylinder would not. For real work, plan for about 465 N at 0.5 MPa, which is roughly 47 kg of vertical lift with a 2:1 safety margin, helping you match it to an actual part weight. The hard-anodized aluminium body and S45C hard-chrome rod resist wear in continuous cycling, and the fixed TPU bumper at both ends absorbs end-of-stroke impact without adjustment.
This model has no magnet fitted, so it cannot trigger a sensor; order the optional -S code to add the magnet for CMSE or DMSE switches. The rod end is female with an M10x1.5 thread, and the port is 1/8" PT. Operating pressure is 0.2-1.0 MPa (28-145 psi), with a proof pressure of 1.5 MPa (215 psi), and speed ranges from 50 to 500 mm/s. The spring returns the rod to its extended home position on air loss, so it does not hold a mid-stroke position under load.

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 (Ø50mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 775.0 N |
| 0.7 MPa | 1127.5 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 ATE50X25 Is Used
Fixture Clamp Retract
Use the ATE50X25 to retract a locating pin or clamp in a CNC fixture after machining. The 775 N pull at 0.5 MPa clears the part, and the spring extends the pin for the next cycle, saving space in the fixture envelope.
Gate Divider Pull
Mount this cylinder on a packaging conveyor to pull a diverter gate back, letting products pass straight. The 25 mm stroke matches typical gate travel, and the compact body fits under the conveyor frame without protruding.
Pallet Stop Release
In an automated warehouse, the ATE50X25 retracts a pallet stop to release a pallet onto a transfer station. The 1127.5 N pull at 0.7 MPa handles the stop's inertia, and the spring returns it to block the next pallet.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE50X25 the Right Cylinder?
For a smaller option, the ATE40X25 offers a 500.3 N pull at 0.5 MPa, while the ATE63X25 steps up to 1320 N at the same pressure, giving you a clear force ladder for sizing. Since this is a single acting pull cylinder, it is best for applications where the load is pulled back by air and the spring returns the rod, not for pushing tasks. The spring does not lock or hold a load in position, so use it where the rod can rest extended when air is off. Mounting options include FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, and FTC brackets, all compatible with the ISO 21287 face. If you need position sensing, remember to order the -S code for the magnet; without it, no sensor can be mounted.
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 ATE50X25 FAQ
The ATE50X25 delivers a net pull of 775 N at 0.5 MPa and 1127.5 N at 0.7 MPa, with the spring force already subtracted. Minimum working pressure is 0.2 MPa, and proof pressure is 1.5 MPa (215 psi). The 50 mm bore uses a 16 mm rod and a 1/8" PT port.
The ATE50X25 has an ISO 21287 compact body that is about 50% shorter than an ISO 15552 profile cylinder, so it fits into machine guards and gantries where a full-length cylinder would not. The fixed TPU bumper at both ends absorbs end-of-stroke energy, and the optional -S magnet enables CMSE or DMSE sensors for position feedback.
