Airtac ATQ Single Acting Thin Cylinder ATQ63X20SB
The AirTAC Airtac ATQ Single Acting Thin Cylinder ATQ63X20SB 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 ATQ63X20SB
The AirTAC ATQ63X20SB 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 extension upon exhaust. This reversed action is ideal for hold-down-release logic. Theoretical pull force is 1401.5N at 0.5MPa and 1962.2N at 0.7MPa; because the return spring consumes energy, actual net output is lower and must be verified from the datasheet.
This SB variant includes a male M18x1.5 rod-end thread for direct load coupling and a built-in piston magnet (-S). The magnet enables position detection using either reed or solid-state electronic switches. Travel is managed by a fixed NBR elastomer bumper at the ends, which is distinct from an adjustable air cushion. Operating pressure spans 0.2-1.0MPa, requiring a 0.2MPa minimum to overcome the spring.

| 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 ATQ63X20SB Is Used
Heavy Pin Extraction
Retracting to physically draw a heavy locking pin out of a machining fixture before unloading the finished component.
Gate Retraction
Pulling a heavy safety gate closed on an automated assembly line, using the spring to safely extend it open during air loss.
Tensioning Mechanism
Applying robust clamping tension on a thick material web, where exhausting the port releases the tension band instantly.
Is the Airtac ATQ Single Acting Thin Cylinder ATQ63X20SB the Right Cylinder?
For sizing within the 12-63mm bore range, consider the ATQ50X20SB if your load requires less theoretical pull (824.6N at 0.5MPa). As the 63mm bore is the largest available in this family, exceeding its capacity would require evaluating alternative cylinder series. The 20mm stroke is well within the 30mm maximum limit for this bore; if your application demands longer travel, you must transition to the double-acting ACQ series. Confirm your ordering criteria carefully: 63mm bore, 20mm stroke, S magnet, and B male rod 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 ATQ63X20SB FAQ
The theoretical pull force (before spring) is 1401.5N at 0.5MPa and 1962.2N at 0.7MPa. The return spring lowers the net output, so confirm exact figures from the datasheet. Operating pressure is 0.2-1.0MPa with a 0.2MPa minimum to overcome the spring, and the maximum standard stroke is 30mm.
Loss of air pressure causes the internal spring to automatically extend the rod to its resting position. End-of-stroke impact is controlled by a fixed NBR elastomer bumper rather than an adjustable cushion; for high-energy cycles, use an external shock absorber or reduce the approach speed.
