Airtac ATE Single Acting Guided Compact Cylinder ATE80X20B
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE80X20B is a genuine single acting, pull (spring return) ISO 21287 compact air cylinder with a Ø80mm bore and 20mm 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 ATE80X20B
This AirTAC ATE80X20B is a single acting pull cylinder, meaning its spring extends the rod and air retracts it, with forces already net of the spring. With an 80 mm bore, it delivers 2159.1 N of pull at 0.5 MPa, enough to handle substantial retraction tasks in tight spaces.
The ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, saving valuable mounting length in automated jigs and gantries. The male rod thread (B code) simplifies attachment, and the fixed TPU bumper at both ends absorbs end-of-stroke energy. For real work, plan on about 1295 N (0.6 times the rating) at 0.5 MPa, which translates to lifting roughly 132 kg vertically with a 2:1 safety margin.

Where the Airtac ATE Single Acting Guided Compact Cylinder ATE80X20B Is Used
Jig Retraction
In a CNC machining center, this cylinder retracts a locating pin from a fixture after clamping, with the spring extending it back into place when air is released. The 2159.1 N pull at 0.5 MPa clears even slightly stuck pins, and the short body fits between the spindle and workholding.
Conveyor Stop
On a pallet conveyor, this unit pulls a stop block down to let a pallet pass, then the spring raises it to halt the next one. The 20 mm stroke is enough to clear the pallet edge, and the fixed TPU bumper prevents loud impacts at high cycle rates.
Gate Actuator
In a packaging line, this cylinder retracts a safety gate to allow product flow, then the spring returns it to the closed position when air is cut. The 80 mm bore provides reliable force to move the gate against light friction, and the compact body mounts easily in the machine frame.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE80X20B the Right Cylinder?
For a lighter retraction task, consider the ATE63X25 with 1320.0 N pull at 0.5 MPa, or step up to the ATE100X25 for 3483.6 N at the same pressure. This 80 mm bore model suits applications needing a strong pull in a compact envelope, but remember it is spring-extend, so it does not hold a mid-stroke position on air loss. The male rod thread and 1/4" port are ready for standard connections, and since this model lacks the -S code, no magnet is fitted for sensors.
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 ATE80X20B FAQ
At 0.5 MPa, the pull force is 2159.1 N, and at 0.7 MPa it is 3101.6 N, both net of the return spring. 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), with a speed range of 50-500 mm/s.
The hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder, so it fits in tight spaces where a full-length cylinder would not. It uses a fixed TPU bumper at both ends to absorb energy, and the male rod thread (B code) allows direct mounting of clevis or rod knuckles. Since this model has no -S code, it has no magnet, so CMSE or DMSE sensors cannot be used unless you order the optional -S version.
