Airtac ATQ Single Acting Thin Cylinder ATQ50X15B
The AirTAC Airtac ATQ Single Acting Thin Cylinder ATQ50X15B is a genuine single-acting COMPACT (JIS) cylinder (single acting, pull type) with a Ø50mm bore and 15mm 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 ATQ50X15B
The AirTAC ATQ50X15B is a single-acting pull-type JIS compact cylinder where supplying air to one port retracts the rod. An internal mechanical spring drives the extension stroke when air exhausts. It delivers a theoretical pull force of 824.6 N at 0.5 MPa and 1154.5 N at 0.7 MPa before accounting for the return spring. The spring lowers the net usable output, so confirming exact net force from the datasheet is recommended.
This 50 mm bore unit features a 20 mm piston rod with an M18x1.5 male thread end for direct load coupling. It operates from 0.2 to 1.0 MPa, needing the 0.2 MPa minimum to overcome the spring. Fixed NBR elastomer bumpers manage end-of-travel impact instead of adjustable air cushions. The body includes magnetic-switch grooves, though this specific configuration ships without a magnet.

| Stroke | 15 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 ATQ50X15B Is Used
Gate Retraction
Pulls a diverter gate closed on a packaging conveyor to halt product flow, allowing the spring to safely extend the gate back open upon air loss.
Pallet Stopper Pull
Retracts a spring-loaded stopper pin on a roller transport line to release loaded pallets, utilizing the 824.6 N theoretical pull at 0.5 MPa.
Tension Release Mechanism
Draws back a tensioning clamp on an assembly fixture to free a workpiece, relying on the fail-safe spring extension to reset the clamp.
Is the Airtac ATQ Single Acting Thin Cylinder ATQ50X15B the Right Cylinder?
For sizing, the adjacent 40 mm bore offers 527.8 N theoretical pull at 0.5 MPa, while the 63 mm bore provides 1401.5 N at 0.5 MPa. If your application requires travel beyond the 30 mm maximum standard stroke for this 50 mm bore, you must switch to a double-acting ACQ cylinder. When ordering, verify the 15 mm stroke, the 50 mm bore, the male rod thread option, and note the absence of the magnet suffix.
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 ATQ50X15B FAQ
It is a single-acting pull cylinder with a 15 mm stroke and a 50 mm bore. The theoretical pull force is 824.6 N at 0.5 MPa and 1154.5 N at 0.7 MPa before spring reduction. It requires a minimum operating pressure of 0.2 MPa to overcome the return spring, and the maximum standard stroke for this bore is 30 mm.
Fixed NBR elastomer bumpers absorb impact at the stroke ends instead of adjustable air cushions. Because it is a pull-type cylinder, loss of air pressure causes the internal spring to fail-safe by extending the rod to its rest position.
