Airtac ATE Single Acting Guided Compact Cylinder ATE63X20SB
The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE63X20SB is a genuine single acting, pull (spring return) ISO 21287 compact air cylinder with a Ø63mm bore and 20mm stroke, 1/8" 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 ATE63X20SB
This AirTAC ATE63X20SB is a single acting pull cylinder with a spring that extends the rod and air that retracts it, giving a net pull of 1320 N at 0.5 MPa. The 63 mm bore and 20 mm stroke fit into tight spaces because the ISO 21287 compact body is about 50% shorter than an ISO 15552 profile cylinder, saving valuable mounting length on automated fixtures.
With the optional -S magnet fitted, this model works with CMSE or DMSE sensors for position feedback, and the male rod thread (B code) simplifies linkage. For real work, plan on about 80 kg of vertical lift at 0.5 MPa (1320 N divided by 9.81, then halved for a 2:1 safety margin), so it can handle moderate part-handling tasks without over-engineering.

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 (Ø63mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 1320.0 N |
| 0.7 MPa | 1903.2 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 ATE63X20SB Is Used
Jig Clamping
Use the ATE63X20SB to pull a clamp arm down onto a workpiece in a CNC milling fixture, where the 20 mm stroke and 1320 N pull secure parts during machining.
Sorting Gate
In a packaging line, this cylinder retracts a diverter gate to route boxes to a secondary conveyor, with the spring returning the gate to the default path when air is off.
Test Rig Actuator
On a quality-control test bench, the ATE63X20SB pulls a probe into contact with a component, applying a consistent 1320 N force at 0.5 MPa to check seal integrity.
Is the Airtac ATE Single Acting Guided Compact Cylinder ATE63X20SB the Right Cylinder?
Choose this 63 mm bore when you need a compact pull action with 1320 N at 0.5 MPa; if your load is lighter, a 50 mm bore provides 775 N at 0.5 MPa, while a larger 80 mm bore delivers 2159.1 N at 0.5 MPa for heavier pulls. The 20 mm stroke is within the standard 25 mm limit for this bore, and the spring extends the rod at rest, so it does not hold a mid-stroke position on air loss. Mount with FA/FB flange, LB foot, CA/CB clevis, or SDB pivot brackets, and order the -S magnet for CMSE/DMSE switches.
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 ATE63X20SB FAQ
The ATE63X20SB provides a net pull force of 1320 N at 0.5 MPa and 1903.2 N at 0.7 MPa, with the spring force already subtracted. The minimum working pressure is 0.2 MPa, and the operating range is 0.2-1.0 MPa (28-145 psi), with a proof pressure of 1.5 MPa (215 psi).
The hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight jigs and guards. The fixed TPU bumper absorbs end-of-stroke impact, and the optional -S magnet allows CMSE or DMSE sensors to detect rod position.
