Airtac ASQ Series Single Acting Slim Cylinder ASQ63X30SB
The AirTAC Airtac ASQ Series Single Acting Slim Cylinder ASQ63X30SB is a genuine single-acting COMPACT (JIS) cylinder (single acting, push type) with a Ø63mm bore and 30mm stroke. Air pushes the rod and an internal spring performs the opposite stroke, so one solenoid line drives the motion — ideal for short-stroke clamping and ejection in tight spaces.

About the Airtac ASQ Series Single Acting Slim Cylinder ASQ63X30SB
The AirTAC ASQ63X30SB is a 63mm bore JIS compact cylinder engineered for single-acting push operation. Supplying air to the single PT1/4 port extends the Ø20mm rod, while an internal mechanical spring handles retraction. This configuration requires just one solenoid valve line, streamlining your pneumatics. At 0.5 MPa it generates 1558.6 N of theoretical push force, climbing to 2182 N at 0.7 MPa. Because an internal return spring consumes some energy, the actual net output is lower than these raw figures—always verify the exact net force from the official datasheet before finalizing your design.
Built with a space-saving riveted body, this unit includes a fixed NBR elastomer bumper at the stroke ends to soften impact rather than relying on adjustable air cushions. The 30mm travel represents the maximum standard stroke for this bore size, as the internal spring limits overall extension length. Equipped with the -S option, the piston carries a magnet for position sensing via reed or solid-state electronic switches. The -B option provides a male M18x1.5 thread on the rod end, allowing direct mechanical coupling to your tooling.

Specifications follow the official AirTAC ACQ-family datasheet. Single-acting types start at 0.2 MPa (the spring must be overcome). Confirm against the product label before installation.
Theoretical Output Force (Ø63mm, Push)
| Pressure | Push force (before spring) |
|---|---|
| 0.5 MPa | 1559 N |
| 0.7 MPa | 2182 N |
These are theoretical air-side forces; the return-spring force reduces the NET usable output. Single-acting push only — the spring performs the opposite stroke. Confirm the net figure from the datasheet and size with a safety margin.

Where the Airtac ASQ Series Single Acting Slim Cylinder ASQ63X30SB Is Used
Heavy-Duty Stamping Ejector
Ejects dense stamped metal components from a hydraulic press bed using a robust 30mm push stroke, relying on the internal spring to retract safely during the pressing cycle.
Automotive Welding Clamp
Holds heavy chassis brackets in position during robotic welding operations, utilizing the male M18x1.5 rod thread for secure fixture mounting and the magnet for stroke confirmation.
Pallet Load Squaring
Pushes corrugated cartons squarely against a guide rail on a high-speed packaging conveyor before stretch wrapping, with the fixed NBR bumper absorbing the sudden stop.
Is the Airtac ASQ Series Single Acting Slim Cylinder ASQ63X30SB the Right Cylinder?
Choosing this 63mm bore provides the highest push capacity in the ASQ family, delivering 1558.6 N theoretical force at 0.5 MPa. If your application requires less force, stepping down to the 50mm bore drops the theoretical output to 981.8 N at 0.5 MPa. Since 63mm is the largest available bore in this compact series, exceeding the 2182 N theoretical limit at 0.7 MPa requires moving to a different cylinder family entirely. The 30mm stroke shown here is the absolute maximum for this bore; if your mechanism needs longer travel, you must switch to the double-acting ACQ series. When ordering, confirm the 63mm bore, 30mm stroke, S magnet for sensing, and B male M18x1.5 rod thread.
Quick checklist
- ✓ Net push force (after spring) at your pressure
- ✓ Stroke ≤ 30 mm (single-acting limit)
- ✓ Single air line saves a valve/port
- ✓ Magnet (S) for sensors?
- ✓ Female (blank) or male (B) rod thread
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.2 – 1.0 MPa operating pressure.
- check Remember the spring performs the return stroke.
- check Avoid side load on the short piston rod.
- check Handle the C-clip carefully; seat it fully in its groove.
- check Installation by qualified personnel per AirTAC docs.
Airtac ASQ Series Single Acting Slim Cylinder ASQ63X30SB FAQ
The theoretical push force is 1558.6 N at 0.5 MPa and 2182 N at 0.7 MPa. These figures represent the raw air-side force before the return spring; the net usable force is lower and must be confirmed from the datasheet. Operating pressure ranges from 0.2 to 1.0 MPa, with the 0.2 MPa minimum necessary to overcome the internal spring. The maximum standard stroke for this 63mm bore is 30 mm.
As a single-acting push type, the cylinder relies on its internal spring to retract the rod automatically to its rest position whenever air pressure is lost or exhausted. This fail-safe behavior ensures the tooling pulls back safely. Deceleration at the stroke ends is handled by fixed NBR elastomer bumpers, not adjustable air cushions; for high kinetic energy loads, consider adding external shock absorbers.
