Airtac ATQ Single Acting Thin Cylinder ATQ63X5SB
The AirTAC Airtac ATQ Single Acting Thin Cylinder ATQ63X5SB is a genuine single-acting COMPACT (JIS) cylinder (single acting, pull type) with a Ø63mm bore and 5mm 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 ATQ63X5SB
The AirTAC ATQ63X5SB is a single-acting PULL-type compact cylinder where compressed air retracts the 20mm piston rod, while an internal spring extends it upon exhaust. It delivers a theoretical pull force of 1401.5N at 0.5MPa and 1962.2N at 0.7MPa. Note that the return spring lowers the net usable output, so always confirm the exact net force from the official datasheet.
Featuring a 63mm bore and a short 5mm stroke, this JIS-form factor actuator operates from 0.2 to 1.0 MPa. The 0.2 MPa minimum is required to overcome the return spring. It uses a fixed NBR elastomer bumper at each end for end-of-travel impact absorption rather than an adjustable air cushion. The -S option includes a built-in piston magnet compatible with reed or solid-state electronic switches, and the -B option provides a male M18x1.5 rod-end thread for direct load coupling.

| 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 ATQ63X5SB Is Used
Web Tension Release
Pulls a tensioning idler roller back 5mm to slacken packaging film webs during machine stoppages or roll changes.
Retractable Guide Gate
Draws a conveyor lane deflector plate inward against spring pressure to temporarily open a diverting path for sorted goods.
Clamp Withdrawal
Releases a holding clamp on an automated machining center by pulling the 20mm rod back 5mm to clear the workpiece.
Is the Airtac ATQ Single Acting Thin Cylinder ATQ63X5SB the Right Cylinder?
For sizing within the 12-63mm bore range, the ATQ50 offers a smaller bore with a theoretical pull of 824.6N at 0.5MPa, making it a lighter alternative if 63mm is oversized. Since 63mm is the largest available bore in this series, there is no larger single-acting pull option. If your application requires a longer travel distance than the 30mm maximum stroke limit for this bore size, you must switch to a double-acting ACQ cylinder. When ordering, verify the 63mm bore, 5mm stroke, -S magnet for sensing, 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 ATQ63X5SB FAQ
This single-acting pull cylinder provides a theoretical pull force of 1401.5N at 0.5MPa and 1962.2N at 0.7MPa before spring deduction. The internal spring extends the rod on exhaust, requiring a 0.2 MPa minimum operating pressure. The maximum standard stroke for a 63mm bore is 30mm, and this specific model has a 5mm stroke.
Loss of air pressure causes the internal spring to automatically extend the rod to its resting position, which is ideal for hold-down-release or tensioning fail-safe logic. Instead of an adjustable air cushion, the cylinder uses a fixed NBR elastomer bumper at each end to absorb impact energy at speeds up to 500 mm/s.
