Airtac ATQ Single Acting Thin Cylinder ATQ50X30B
The AirTAC Airtac ATQ Single Acting Thin Cylinder ATQ50X30B 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 ATQ50X30B
The AirTAC ATQ50X30B is a JIS compact single-acting PULL cylinder. Feeding air to the single PT1/4 port retracts the piston rod, while exhausting that line allows an internal spring to push it back out. This makes the powered motion a pull, with a fail-safe spring-extend behavior that naturally suits hold-down-release or tensioning tasks. With a 50mm bore, it provides a theoretical pull force of 824.6N at 0.5 MPa and 1154.5N at 0.7 MPa before spring deduction.
This specific variant features a male M18x1.5 threaded rod end for direct load coupling. It carries a fixed NBR elastomer bumper at each end to soften end-of-stroke impact rather than relying on an adjustable air cushion. The 30mm stroke represents the maximum standard travel for this bore size, and the body includes magnetic-switch grooves ready for external sensors, though this unit ships without a magnet.
Airtac ATQ Single Acting Thin Cylinder ATQ50X30B Technical Specifications

| Series | ATQ JIS compact single-acting cylinder |
| 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 ATQ50X30B Is Used
Hold-Down Release
Ideal for clamping fixtures where air pulls a hold-down tight, and loss of pressure safely releases the clamp via the spring-extend action.
Gate Retraction
Used on packaging lines to pull a diverter gate inward, allowing the internal spring to push the gate back to its open rest position when air is removed.
Tensioning Mechanism
Maintains belt or wire tension by pulling against a load, with the male M18x1.5 rod end securing the tensioning pulley directly.
Is the Airtac ATQ Single Acting Thin Cylinder ATQ50X30B the Right Cylinder?
For a 50mm bore, the ATQ50X30B offers the maximum 30mm single-acting travel. If you need less pull force, the neighboring 40mm bore provides a 527.8N theoretical pull at 0.5 MPa; stepping up to the 63mm bore yields 1401.5N at 0.5 MPa. Should your application require a longer stroke than 30mm, you must switch to the double-acting ACQ series. When ordering, verify the 50mm bore, 30mm stroke, the male M18x1.5 rod thread, and note that this SKU omits the -S magnet.
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 ATQ50X30B FAQ
It delivers a theoretical pull of 824.6N at 0.5 MPa and 1154.5N at 0.7 MPa before the return spring is factored in. The spring lowers net output, so verify exact net force from the datasheet. It has a 30mm stroke (the maximum for this bore) and operates from 0.2 to 1.0 MPa.
Since it is a single-acting pull type, losing air pressure causes the internal spring to extend the rod to its rest position. To manage impact at the ends of travel, the cylinder uses a fixed NBR elastomer bumper rather than an adjustable air cushion.
