Airtac ATE Single Acting Guided Compact Cylinder ATE25X15SB
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE25X15SB is a genuine single acting, pull (spring return) ISO 21287 compact air cylinder with a Ø25mm bore and 15mm 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 ATE25X15SB
This is a single acting pull cylinder from AirTAC, built to the ISO 21287 compact standard. The spring extends the 10 mm rod, and air retracts it, delivering a net pull of 170.9 N at 0.5 MPa (253.3 N at 0.7 MPa) after accounting for the spring force. Its hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder, making it a fit for tight machine guarding and compact jigs.
The body features a roller-burnished bore for smooth operation, and the S45C piston rod is hard-chrome plated for wear resistance. This model includes the optional -S magnet, so you can mount CMSE or DMSE sensors to confirm the rod position. With a fixed TPU bumper at both ends, it decelerates gently at stroke limits, and the minimum working pressure to overcome the spring is 0.2 MPa.

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 ATE25X15SB Is Used
Jig Clamping
Use the 170.9 N pull at 0.5 MPa to retract a locating pin in a CNC fixture. The compact body fits between vise jaws, and the spring return extends the pin when air is released, clearing the part for unloading.
Gate Locking
In a small parts hopper, this cylinder can pull a sliding gate shut. The spring extends the gate to block parts, and air retracts it to release a metered flow. The 15 mm stroke is ideal for thin gates.
Belt Tensioner
Mount this cylinder to pull a tensioner arm on a light conveyor. The 170.9 N force keeps the belt taut, while the TPU bumper absorbs the end-of-stroke shock. The optional -S magnet lets a sensor confirm the arm is in the retracted position.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE25X15SB the Right Cylinder?
For a lighter pull, the 20 mm bore ATE20X25 delivers 88.1 N at 0.5 MPa, while stepping up to the 32 mm bore ATE32X25 provides 296.0 N at the same pressure. This 25 mm bore unit offers a balance of force and compact size for moderate loads. Remember, the spring extends the rod at rest, so it does not hold a mid-stroke position on air loss. With the -S magnet fitted, you can use CMSE or DMSE switches for position sensing, and the M5x0.8 port suits small-bore plumbing.
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 ATE25X15SB FAQ
This single acting pull cylinder provides a net pull of 170.9 N at 0.5 MPa and 253.3 N at 0.7 MPa, with the spring force already subtracted. 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 ATE25X15SB has a short body that saves about 50% of the mounting length compared to an ISO 15552 profile cylinder. This makes it suitable for tight spaces. It also has a fixed TPU bumper at both ends to absorb impact, and the optional -S magnet allows for CMSE or DMSE sensor mounting to detect the rod position.
