Airtac ATE Single Acting Guided Compact Cylinder ATE100X20SB
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE100X20SB is a genuine single acting, pull (spring return) ISO 21287 compact air cylinder with a Ø100mm 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 ATE100X20SB
A single acting pull cylinder with spring return, the ATE100X20SB keeps the rod normally extended: the spring pushes it out and compressed air retracts it, delivering 3483.6 N of pull at 0.5 MPa (4991.6 N at 0.7 MPa), both figures already net of the spring. Built to ISO 21287, its short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so a 100 mm bore fits clamping stations and press fixtures where a full-length body simply will not go.
The hard-anodized aluminium body carries a roller-burnished bore, and the 20 mm S45C rod is hard-chrome plated with a male thread (the B code) for direct fixture attachment. At this force class, plan on roughly 2090 N of usable work at 0.5 MPa - about 213 kg - rather than the full rating. The S in the model code means the optional -S magnet is fitted, so CMSE / DMSE switches can be clipped onto the body slots for end-of-stroke sensing. Air supply must be filtered to 40 um; working range is 0.2-1.0 MPa (28-145 psi) with 0.2 MPa as the minimum to overcome the spring, and speed runs 50-500 mm/s.

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 (Ø100mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 3483.6 N |
| 0.7 MPa | 4991.6 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 ATE100X20SB Is Used
Heavy clamp release in weld fixtures
Spring holds the clamp open and air pulls the 20 mm rod to release a stamped automotive bracket - 3483.6 N at 0.5 MPa clears welded parts without a powered extend line.
Slide retraction on a press loader
The normally extended rod keeps a locating slide home; on command, air retracts it 20 mm so a steel billet can drop into the die, failing safe to extended on air loss.
Gate latch pull on pallet conveyors
Air retracts the latch pin against the spring between pallets; the short ISO 21287 body tucks under the conveyor frame where a full-length profile cylinder would collide.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE100X20SB the Right Cylinder?
For short-stroke retraction work around 3483.6 N at 0.5 MPa, this 100 mm bore is the right class: step down to ATE80X20SB (2159.1 N) for lighter clamps or accept that a smaller bore cannot reach this pull. Vertically, the rod can lift about 177 kg with a 2:1 margin - match that against your part weight before ordering. Remember the spring returns the rod to its extended home position on air loss and will not hold a mid-stroke point. Mount with FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot or FTC brackets, all of which bolt straight to the ISO 21287 face; I and Y rod knuckles suit the male thread. If you need a powered return stroke instead of a spring, choose the ACE double-acting version; for a normally retracted push action, look at ASE.
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 ATE100X20SB FAQ
Net of the return spring, pull is 3483.6 N at 0.5 MPa and 4991.6 N at 0.7 MPa. Working pressure is 0.2-1.0 MPa (28-145 psi) with 0.2 MPa the minimum needed to beat the spring, proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C, speed 50-500 mm/s, and air filtered to 40 um. The spring extends the rod; air retracts it, so the cylinder is normally extended at rest.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and a fixed TPU bumper at both ends absorbs end-of-stroke energy. The S in ATE100X20SB means the optional -S magnet is fitted on this unit, so CMSE / DMSE reed or solid-state switches can be mounted in the body slots; models ordered without -S carry no magnet. FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot and FTC brackets bolt straight to the mounting face.
