Airtac ASQ Series Single Acting Slim Cylinder ASQ50X30SB
The AirTAC Airtac ASQ Series Single Acting Slim Cylinder ASQ50X30SB is a genuine single-acting COMPACT (JIS) cylinder (single acting, push type) with a Ø50mm 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 ASQ50X30SB
The AirTAC ASQ50X30SB is a 50mm JIS compact single-acting push cylinder. Air delivered to one port extends the rod, while an internal mechanical spring handles retraction upon exhaust. This design requires only a single solenoid valve, simplifying your pneumatic plumbing. It delivers a theoretical push force of 981.8N at 0.5 MPa and 1374.4N at 0.7 MPa before the spring resistance is factored in; always verify the net output from the official datasheet for your specific load.
This unit includes a -S magnet for position sensing via reed or solid-state switches, and a -B male M18x1.5 rod end that couples directly to tooling. It features a fixed NBR elastomer bumper to manage end-of-stroke energy rather than an adjustable air cushion. Because the return spring occupies internal length, the stroke is capped at 30mm; if your application requires longer travel, a double-acting ACQ series cylinder is the better choice.
Airtac ASQ Series Single Acting Slim Cylinder ASQ50X30SB Technical Specifications
| Model | Airtac ASQ Series Single Acting Slim Cylinder ASQ50X30SB |
|---|---|
| Series | ASQ JIS compact single-acting cylinder |
| Bore size | Ø50 mm |
| Stroke | 30 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 ASQ50X30SB Is Used
CNC Vise Clamping
Provides robust holding force for aluminum workpieces during light CNC milling, utilizing the male thread for direct fixture mounting.
Carton Flap Folding
Extends rapidly to fold corrugated box flaps prior to tape sealing, with the spring ensuring a safe retract if air pressure drops.
Stamping Ejector
Pushes formed sheet metal parts out of a press die cavity, relying on the fixed NBR bumper to absorb the impact at full extension.
Is the Airtac ASQ Series Single Acting Slim Cylinder ASQ50X30SB the Right Cylinder?
For sizing within the 12-63mm ASQ range, stepping down to a 40mm bore drops the 0.5 MPa theoretical push to 628.3N, while stepping up to a 63mm bore raises it to 1558.6N. If your mechanism needs a stroke beyond the 30mm maximum allowed for this 50mm bore, you must switch to the double-acting ACQ equivalent. When ordering this exact configuration, confirm the 50mm bore, 30mm stroke, the S magnet option, and the B male M18x1.5 rod thread to ensure proper integration with your PT1/4 ported air supply.
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 ASQ50X30SB FAQ
The theoretical push force is 981.8N at 0.5 MPa and 1374.4N at 0.7 MPa before spring deduction; verify net force from the datasheet. It is a single-acting push cylinder requiring 0.2-1.0 MPa to overcome the return spring, with a maximum stroke of 30mm.
The -S option provides a piston magnet compatible with both reed and electronic solid-state switches. End-of-stroke energy is absorbed by a fixed NBR elastomer bumper, not an adjustable air cushion, so external shock absorbers may be needed for high-speed loads.
