Airtac ATE Single Acting Guided Compact Cylinder ATE25X25B
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE25X25B is a genuine single acting, pull (spring return) ISO 21287 compact air cylinder with a Ø25mm bore and 25mm stroke, M5×0.8 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 ATE25X25B
A single acting pull cylinder built to the ISO 21287 compact format, the ATE25X25B uses a 25 mm bore and 25 mm stroke with a 10 mm male-threaded rod (the B code). A spring holds the rod extended and compressed air retracts it, so at 0.5 MPa you get 170.9 N of pull net of the spring, rising to 253.3 N at 0.7 MPa. The hard-anodized aluminium body with a roller-burnished bore and S45C hard-chrome-plated rod stands up to continuous jig work, and a fixed TPU bumper at each end absorbs end-of-stroke shock.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight clamping fixtures and guarded stations a full-length body cannot reach. For positioning, add the optional -S magnet code so CMSE or DMSE switches can read end positions; without -S there is no magnet in the body. As a sizing rule, treat roughly 102 N (about 60% of the 0.5 MPa rating) as your usable pull, which lifts around 8.7 kg vertically with a 2:1 margin.

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 (Ø25mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 170.9 N |
| 0.7 MPa | 253.3 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 ATE25X25B Is Used
Spring-out clamp retraction
On a small fixture for aluminium brackets, the spring keeps the clamp engaged and air pulls the rod back 25 mm to release the part between cycles.
Slide return on a dial table
A 25 mm retract stroke clears a locating pin on an indexing rotary table; 170.9 N at 0.5 MPa is enough for the light spring-loaded slide.
Position-flagged gate on a filler
With the optional -S magnet, a DMSE switch confirms the gate has retracted before the fill head steps, protecting a bottling line interlock.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE25X25B the Right Cylinder?
At 170.9 N pull at 0.5 MPa, this 25 mm bore suits light clamping and part-return duty. Step down to the 20 mm bore (88.1 N at 0.5 MPa) for gentler retraction, or up to the 32 mm bore (296.0 N at 0.5 MPa) when the load grows. Remember the spring returns the rod to its extended home on air loss and will not hold a mid-stroke position, so add a separate stop if you need one. FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot and FTC mounts bolt straight to the ISO 21287 face, and the male rod thread (B) takes I or Y knuckles directly. Order the -S code if CMSE or DMSE switching is planned.
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 ATE25X25B FAQ
It is a single acting pull cylinder: the spring extends the rod and air retracts it. Pull is 170.9 N at 0.5 MPa and 253.3 N at 0.7 MPa, both net of the return spring. Minimum working pressure is 0.2 MPa, range 0.2-1.0 MPa (28-145 psi), proof 1.5 MPa (215 psi), speed 50-500 mm/s, temperature -20 to +70 C, air filtered to 40 um. Port is M5x0.8, rod thread is male, and stroke is 25 mm.
The ISO 21287 compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits shallow fixtures and guarded areas. Switch sensing is not fitted as standard: order the optional -S magnet code to enable CMSE or DMSE switches; without -S the body carries no magnet. A fixed TPU bumper at both ends softens end-of-stroke contact.
