Airtac ATQ Single Acting Thin Cylinder ATQ63X15B
The AirTAC Airtac ATQ Single Acting Thin Cylinder ATQ63X15B is a genuine single-acting COMPACT (JIS) cylinder (single acting, pull type) with a Ø63mm 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 ATQ63X15B
The AirTAC ATQ63X15B is a JIS compact cylinder engineered for single-acting PULL operation. Feeding compressed air to the single PT1/4 port retracts the 20mm piston rod, while an internal mechanical spring drives its extension upon exhaust. This fail-safe design naturally defaults to the extended position, making it well-suited for hold-down-release or tensioning workflows where unpressurized retraction is undesirable. Delivering a theoretical pull force of 1401.5 N at 0.5 MPa (and 1962.2 N at 0.7 MPa) before accounting for the return spring, it handles substantial loads within a minimal footprint.
This 63mm bore unit features a fixed NBR elastomer bumper at each end to soften end-of-stroke impacts, deliberately avoiding complex adjustable air cushions. It includes a male M18x1.5 threaded rod end for direct load coupling. Although the body retains standard magnetic-switch grooves, this specific configuration ships without the internal magnet. Operating effectively between 0.2-1.0 MPa, it sustains speeds of 50-500 mm/s across its 15mm travel.

| 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 (Ø63mm, Pull)
| Pressure | Pull force (before spring) |
|---|---|
| 0.5 MPa | 1402 N |
| 0.7 MPa | 1962 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 ATQ63X15B Is Used
Press Ejection Pin Retrieval
Draws heavy ejection pins back inside molding machinery, relying on the robust spring to safely push the pins outward when the air supply cuts off.
Heavy Conveyor Gate Retraction
Pulls a heavy diverter gate closed on a sorting line, using the male M18x1.5 thread for a rigid linkage while the spring firmly opens it during halts.
Pneumatic Tensioning System
Maintains steady belt or cable tension in large packaging equipment, pulling the tensioning idler back against the load and extending it upon pressure loss.
Is the Airtac ATQ Single Acting Thin Cylinder ATQ63X15B the Right Cylinder?
For sizing down within the 12-63mm range, the 50mm bore variant offers a lower theoretical pull of 824.6 N at 0.5 MPa, which may better suit lighter tensioning duties. If your mechanism requires a longer extension distance exceeding the 30mm maximum standard stroke for this bore, transitioning to a double-acting ACQ series cylinder becomes necessary. When finalizing this configuration, verify the 63mm bore, 15mm stroke, the male M18x1.5 rod thread, and confirm the absence of the -S magnet option to ensure seamless integration.
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 ATQ63X15B FAQ
This single-acting PULL cylinder uses air to retract the rod and a spring to extend it. It has a 63mm bore, a 15mm stroke (maximum standard stroke is 30mm), and requires a minimum operating pressure of 0.2 MPa. The theoretical pull force is 1401.5 N at 0.5 MPa and 1962.2 N at 0.7 MPa; because an internal spring performs the extension, actual net output force is lower and should be confirmed from the datasheet.
It relies on a fixed NBR elastomer bumper at each end to absorb impact energy, rather than an adjustable air cushion. In the event of air pressure loss, the internal spring automatically pushes the rod to the extended rest position, providing a reliable fail-safe mechanism for your mechanical sequence.
