Airtac ATQ Single Acting Thin Cylinder ATQ63X20B
The AirTAC Airtac ATQ Single Acting Thin Cylinder ATQ63X20B is a genuine single-acting COMPACT (JIS) cylinder (single acting, pull type) with a Ø63mm bore and 20mm 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 ATQ63X20B
The AirTAC ATQ63X20B is a JIS compact single-acting pull cylinder. Feeding air to the single PT1/4 port retracts the 20mm rod, while an internal spring drives the extension stroke upon exhaust. This fail-safe behavior ensures the rod extends to its rest position if air pressure drops, which is ideal for hold-down-release or tensioning operations. It operates reliably from a 0.2 MPa minimum pressure up to 1.0 MPa.
At 0.5 MPa, this 63mm bore unit provides a theoretical pull force of 1401.5 N before spring resistance, reaching 1962.2 N at 0.7 MPa. The return spring lowers the net output, so you should confirm exact net force values from the datasheet. This variant includes a male M18x1.5 rod-end thread for direct load coupling, fixed NBR bumpers for end-of-stroke impact absorption, and body sensor grooves, though it ships without a magnet.

| Bore size | Ø63 mm |
| Stroke | 20 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 (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 ATQ63X20B Is Used
Tensioning Clamps
Pulls heavy material taut during machining by retracting the rod against spring resistance, then releases tension automatically via spring extension when air is exhausted.
Heavy Gate Retraction
Draws back a substantial safety gate or heavy stop block on automated assembly lines using the male M18x1.5 thread for a rigid mechanical linkage.
Press Hold-Down Release
Holds a large workpiece securely by pulling a clamp down during processing, utilizing the fail-safe spring extension to lift the clamp and free the part on air loss.
Is the Airtac ATQ Single Acting Thin Cylinder ATQ63X20B the Right Cylinder?
For sizing, the ATQ63X20B sits at the top of the compact series. If 1401.5 N theoretical pull at 0.5 MPa is excessive, step down to the 50mm bore (824.6 N). There is no larger bore in this family. This model has a 20mm stroke, safely under the 30mm maximum for single-acting versions. If your application requires longer travel, switch to the double-acting ACQ series. When ordering, verify the 63mm bore, 20mm stroke, male M18x1.5 rod thread, and note the absence of 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 ATQ63X20B FAQ
This 63mm bore cylinder has a 20mm stroke (max 30mm for this size). It provides a theoretical pull force of 1401.5 N at 0.5 MPa and 1962.2 N at 0.7 MPa before the return spring. The spring lowers net output, so verify exact net force from the datasheet. It requires a 0.2 MPa minimum operating pressure to overcome the spring.
It uses fixed NBR elastomer bumpers at the stroke ends to absorb impact, rather than adjustable air cushions. For high-energy cycles, you may need an external shock absorber. Because it is a single-acting pull type, losing air pressure causes the internal spring to automatically extend the rod to its outward rest position.
