Airtac ASQ Series Single Acting Slim Cylinder ASQ50X5SB
The AirTAC Airtac ASQ Series Single Acting Slim Cylinder ASQ50X5SB is a genuine single-acting COMPACT (JIS) cylinder (single acting, push type) with a Ø50mm bore and 5mm 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 ASQ50X5SB
The AirTAC ASQ50X5SB is a single-acting, push-type JIS compact cylinder where air extends the rod and an internal mechanical spring handles retraction. Feeding one pneumatic line simplifies plumbing while providing a fail-safe retract when pressure drops. It features a 50mm bore and 5mm stroke, generating a theoretical push force of 981.8N at 0.5 MPa and 1374.4N at 0.7 MPa before spring deduction. You should verify the exact net output from the official datasheet, as the return mechanism consumes a portion of this raw energy.
This specific configuration includes the -S magnet for tracking position with reed or solid-state electronic switches, plus the -B option for an M18x1.5 male piston rod end that attaches directly to tooling. Instead of adjustable pneumatic cushions, it relies on fixed NBR elastomer bumpers to soften end-of-stroke impacts. Operating pressure spans 0.2-1.0 MPa, requiring a minimum of 0.2 MPa to overcome the internal spring tension.

| Series | ASQ JIS compact single-acting cylinder |
| Bore size | Ø50 mm |
| Stroke | 5 mm |
| Acting type | Single acting, push type |
| Port size | PT1/4 |
| Rod end thread | M10×1.5 female / M18×1.5 male (B) |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.2 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 50 – 500 mm/s |
| Cushion | Bumper |
| Max standard stroke | Up to 30 mm |
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 (Ø50mm, Push)
| Pressure | Push force (before spring) |
|---|---|
| 0.5 MPa | 982 N |
| 0.7 MPa | 1374 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 ASQ50X5SB Is Used
Stamping Ejector
Pushes small metal or plastic blanks out of a progressive die press using the M18x1.5 male rod end for rapid tooling swaps.
Package Diverter
Extends a 5mm paddle to briefly contact and reroute lightweight cartons on a packaging line, relying on spring retraction for a fast reset.
Part Hold-Down
Applies a brief clamping force to hold a wooden workpiece stationary beneath a CNC routing head during automated machining.
Is the Airtac ASQ Series Single Acting Slim Cylinder ASQ50X5SB the Right Cylinder?
For a 50mm bore, the theoretical push output is 981.8N at 0.5 MPa. If your application requires less force, stepping down to a 40mm bore yields 628.3N, while moving up to a 63mm bore provides 1558.6N. This 5mm stroke is well within the 30mm maximum limit for this size. If your design requires longer travel than 30mm, you must switch to the double-acting ACQ series. To finalize your order, confirm the 50mm bore, 5mm stroke, the -S magnet for sensing, and the -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 ASQ50X5SB FAQ
The theoretical push force is 981.8N at 0.5 MPa and 1374.4N at 0.7 MPa, though the internal return spring lowers the net usable output. Operating pressure is 0.2-1.0 MPa, requiring a 0.2 MPa minimum to overcome the spring, and the maximum stroke for a 50mm bore is 30mm.
It is single-acting, so if air pressure is lost or exhausted, the internal spring automatically retracts the rod to its rest position. End-of-travel impact is absorbed by fixed NBR elastomer bumpers rather than adjustable pneumatic cushions, meaning external shock absorbers may be needed for high-energy loads.
