Airtac ATQ Single Acting Thin Cylinder ATQ63X20S
The AirTAC Airtac ATQ Single Acting Thin Cylinder ATQ63X20S 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 ATQ63X20S
The AirTAC ATQ63X20S is a 63mm JIS compact cylinder engineered for single-acting PULL operation. Supplying air to the single PT1/4 port retracts the Ø20mm rod, while an internal mechanical spring drives the extension stroke upon exhaust. This configuration is ideal for hold-down-release tasks where unpowered extension is required. Theoretical pull force is 1401.5N at 0.5MPa and 1962.2N at 0.7MPa (before spring); verify net output via the datasheet as the return mechanism lowers usable force.
This 20mm travel unit stays within the 30mm maximum stroke limit for this bore size. It integrates a fixed NBR elastomer bumper at each end to soften impact, rather than an adjustable air cushion. The included -S piston magnet enables tracking by both reed and solid-state electronic switches via the body grooves. Operating pressure spans 0.2-1.0MPa, with 0.2MPa as the floor to overcome the spring.
Airtac ATQ Single Acting Thin Cylinder ATQ63X20S Technical Specifications

| 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 ATQ63X20S Is Used
Packaging Line Hold-Down
Retracts a clamping pin on a packaging conveyor to release cartons, using the spring to safely extend the stop when air is removed.
Stamping Press Tensioner
Pulls a gripper closed to maintain belt tension on a stamping press, relying on the 1401.5N theoretical pull at 0.5MPa.
Sorter Gate Retraction
Draws back a sorting gate on a warehouse diverter, allowing the internal spring to fail-safe extend the barrier during pressure loss.
Is the Airtac ATQ Single Acting Thin Cylinder ATQ63X20S the Right Cylinder?
For slightly lower force, the 50mm bore offers 824.6N theoretical pull at 0.5MPa; if 1962.2N at 0.7MPa is insufficient, note that 63mm is the largest ATQ bore. If your application needs travel beyond 30mm, switch to the double-acting ACQ series. When ordering this 63mm bore unit, verify the 20mm 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 ATQ63X20S FAQ
It provides a theoretical pull of 1401.5N at 0.5MPa and 1962.2N at 0.7MPa before the spring. The internal spring extends the rod on exhaust. Operating pressure is 0.2-1.0MPa (0.2MPa minimum to overcome the spring), and max standard stroke for a 63mm bore is 30mm.
It uses a fixed NBR elastomer bumper at each end to absorb impact, not an adjustable air cushion. For high-energy cycles, slow the approach or add an external shock absorber. The -S magnet works with reed or electronic solid-state switches in the body grooves.
