Airtac ATE Single Acting Guided Compact Cylinder ATE80X25SB
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE80X25SB is a genuine single acting, pull (spring return) ISO 21287 compact air cylinder with a Ø80mm 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 ATE80X25SB
A single acting pull cylinder with spring return, the ATE80X25SB keeps the rod normally extended: the internal spring pushes it out, and compressed air retracts it. At 0.5 MPa the net pull is 2159.1 N after the spring is subtracted, rising to 3101.6 N at 0.7 MPa, so this 80 mm bore handles heavy clamping and hold-down work where a compact footprint matters. Air filtered to 40 um at 0.2-1.0 MPa (28-145 psi) drives it, with a speed range of 50-500 mm/s.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why this large-bore version fits into tight press fixtures and gantry clamps that cannot accept a full-length body. The hard-anodized aluminium bore resists wear, the 20 mm S45C hard-chrome rod stands up to side loading better than smaller rods, and a fixed TPU bumper at each end absorbs end-of-stroke shock. At 0.5 MPa, plan on roughly 1295 N of real work (about 0.6 of the rated pull), which is the vertical lift equivalent of roughly 66 kg - halve that to about 33 kg if you want a 2:1 margin on a lifting fixture.

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 (Ø80mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 2159.1 N |
| 0.7 MPa | 3101.6 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 ATE80X25SB Is Used
Press fixture hold-down
The spring keeps hold-down pads extended over aluminum extrusions on a CNC press table; 2159.1 N net pull at 0.5 MPa retracts them only when the cycle commands it.
Pallet clamp on a machining line
Normally-extended clamps lock pallets into a transfer line fixture; the 25 mm stroke clears just enough for pallet change, and the short body fits under the fixture plate.
Battery pack lid latch
In an EV assembly cell, the spring-extended rod latches heavy battery lids; 0.2 MPa minimum air is enough to release, and CMSE switches (via the -S magnet) confirm latch state.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE80X25SB the Right Cylinder?
Size by net pull: if 2159.1 N at 0.5 MPa is more than you need, the ATE63X25SB delivers 1320.0 N at the same pressure; if you need more, the ATE100X25SB reaches 3483.6 N. Remember the spring only returns the rod to its extended home position on air loss - it will not hold a mid-stroke position, so add a stop or external lock if your process needs one. The male rod thread (B code) pairs with I or Y rod knuckles, and FA/FB flanges, LB feet, CA/CB clevises, CR, SDB pivot or FTC brackets bolt straight to the ISO 21287 face. This model carries the optional -S magnet, so CMSE / DMSE switches can be mounted for end-of-stroke signaling.
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 ATE80X25SB FAQ
Net of the return spring, pull is 2159.1 N at 0.5 MPa and 3101.6 N at 0.7 MPa. It runs on air filtered to 40 um at 0.2-1.0 MPa (28-145 psi), proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C, speed 50-500 mm/s. The spring extends the rod; air retracts it, and at least 0.2 MPa is needed to overcome the spring.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body and a 20 mm hard-chrome plated S45C rod. A fixed TPU bumper at each end absorbs end-of-stroke shock; it only decelerates the rod and never locks or holds a load. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be clamped to the body for end-of-stroke detection.
