Airtac ATE Single Acting Guided Compact Cylinder ATE63X25
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE63X25 is a genuine single acting, pull (spring return) ISO 21287 compact air cylinder with a Ø63mm 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 ATE63X25
A single acting pull cylinder of the ISO 21287 compact family, the ATE63X25 keeps its rod normally extended by an internal spring and uses air pressure only to retract it. At 0.5 MPa the net pull is 1320 N (1903.2 N at 0.7 MPa, already deducted for the spring), driven through a 16 mm hard-chrome-plated S45C rod with a female M10x1.5 thread and a 1/8" PT port. Minimum working pressure is 0.2 MPa, the speed range is 50-500 mm/s, and the fluid must be air filtered to 40 um.
The short ISO 21287 body cuts roughly 50% of the mounting length you would need for an ISO 15552 profile cylinder, which is why this bore class slots into cramped welding fixtures and press-side tooling. On the buyer side, the 1320 N net pull at 0.5 MPa translates to a vertical lift of about 134 kg, and with a 2:1 margin you should plan on lifting roughly 67 kg vertically. A fixed TPU bumper at each end absorbs end-of-stroke shock, and the hard-anodized aluminium body resists wear in high-cycle duty.

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 (Ø63mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 1320.0 N |
| 0.7 MPa | 1903.2 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 ATE63X25 Is Used
Welding fixture clamping
The spring-extended rod holds a locating pin or gate out of the weld zone; 1320 N of retraction at 0.5 MPa pulls the tool clear each cycle, and the short body fits inside the fixture frame.
Press-side part ejector
Mounted on a stamping cell, the 25 mm stroke kicks finished blanks off the die table; the 1/8" port and 50-500 mm/s speed keep ejection fast and repeatable.
Pallet-stacker gate latch
In warehouse gate and latch mechanisms the normally-extended spring keeps the latch engaged on air loss, while about 67 kg of safe vertical lift capacity covers heavy gate hardware.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE63X25 the Right Cylinder?
Size against neighbours: the ATE50X25 pulls 775 N at 0.5 MPa, while stepping up to the ATE80X25 gives 2159.1 N, so the 63 mm bore at 1320 N sits squarely in the mid-heavy retraction class. Remember that the spring only returns the rod to its extended home position on air loss; it will not hold a mid-stroke position, so use a stop or external lock if you need one. Bolt it down with FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot or FTC brackets, and if you want position detection, order the -S code so CMSE / DMSE switches can ride the body - without -S there is no magnet fitted.
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 ATE63X25 FAQ
Net of the return spring, the ATE63X25 pulls 1320 N at 0.5 MPa and 1903.2 N at 0.7 MPa. Operating pressure is 0.2-1.0 MPa (28-145 psi) with a 1.5 MPa (215 psi) proof rating, and at least 0.2 MPa is required to overcome the spring. Speed range is 50-500 mm/s on air filtered to 40 um, over a -20 to +70 C temperature span.
The ISO 21287 compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and a fixed TPU bumper at each end absorbs end-of-stroke impact. Sensors are possible only with the optional -S magnet code, which lets CMSE / DMSE switches mount on the body; the standard ATE63X25 ships with no magnet, and mounting options include FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot and FTC.
