Airtac ATQ Single Acting Thin Cylinder ATQ50X30S
The AirTAC Airtac ATQ Single Acting Thin Cylinder ATQ50X30S is a genuine single-acting COMPACT (JIS) cylinder (single acting, pull type) with a Ø50mm bore and 30mm stroke. Air pulles 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 ATQ Single Acting Thin Cylinder ATQ50X30S
The AirTAC ATQ50X30S is a JIS compact single-acting pull-type cylinder. Feeding air to the single PT1/4 port retracts the Ø20 mm rod, while an internal spring extends it upon exhaust. This makes the powered motion a pull, leaving the extend stroke to the spring. It delivers a theoretical pull force of 824.6 N at 0.5 MPa and 1154.5 N at 0.7 MPa before the return spring's resistance is factored in.
Because the return spring lowers the net usable output, you should confirm the exact net force from the datasheet. Operating pressure must be at least 0.2 MPa to overcome the spring. This 50 mm bore unit includes a fixed NBR elastomer bumper at each end for end-of-stroke contact, and the -S suffix provides a built-in piston magnet compatible with reed or solid-state electronic switches.
Airtac ATQ Single Acting Thin Cylinder ATQ50X30S Technical Specifications

| Bore size | Ø50 mm |
| Stroke | 30 mm |
| Acting type | Single acting, pull 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, Pull)
| Pressure | Pull force (before spring) |
|---|---|
| 0.5 MPa | 825 N |
| 0.7 MPa | 1155 N |
These are theoretical air-side forces; the return-spring force reduces the NET usable output. Single-acting pull only — the spring performs the opposite stroke. Confirm the net figure from the datasheet and size with a safety margin.

Where the Airtac ATQ Single Acting Thin Cylinder ATQ50X30S Is Used
Wire Tensioning
Pulls a tensioning idler back against a cable assembly on a wire drawing machine, releasing tension safely when air pressure drops.
Pallet Stopper Retract
Draws a spring-loaded pallet stop gate down out of the conveyor path to let packaged boxes pass on a packaging line.
Clamp Release
Retracts a holding clamp on a CNC fixture, allowing the internal spring to push the jaws open for metal part unloading.
Is the Airtac ATQ Single Acting Thin Cylinder ATQ50X30S the Right Cylinder?
For sizing context, dropping to a 40 mm bore yields a 527.8 N theoretical pull at 0.5 MPa, while stepping up to a 63 mm bore provides 1401.5 N. This 50 mm model hits a solid middle ground for heavier tensioning tasks. The 30 mm stroke is the maximum standard single-acting travel for this bore; if your application requires a longer retraction distance, you must switch to a double-acting ACQ cylinder. When ordering, verify the 50 mm bore, 30 mm stroke, the -S magnet for sensing, and the default female M10x1.5 rod-end thread.
Quick checklist
- ✓ Net pull 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 ATQ Single Acting Thin Cylinder ATQ50X30S FAQ
It provides a theoretical pull force of 824.6 N at 0.5 MPa and 1154.5 N at 0.7 MPa before the spring. The internal spring extends the rod on exhaust, requiring a 0.2 MPa minimum operating pressure. The maximum standard stroke is 30 mm.
If air pressure is lost, the internal spring automatically extends the rod to its rest position. At the end of travel, a fixed NBR elastomer bumper absorbs impact. It is not an adjustable air cushion, so for high kinetic energy loads you should slow the approach or use an external shock absorber.
