Airtac ATQ Single Acting Thin Cylinder ATQ63X5S
The AirTAC Airtac ATQ Single Acting Thin Cylinder ATQ63X5S 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 ATQ63X5S
The AirTAC ATQ63X5S is a single-acting pull-type JIS compact cylinder. Feeding air to its single PT1/4 port retracts the 20mm rod, while an internal spring drives the extend motion upon exhaust. It delivers a 1401.5 N theoretical pull at 0.5 MPa (1962.2 N at 0.7 MPa) before the return spring lowers the net output, which you should confirm from the datasheet.
Designed for short-stroke tasks, this 5mm travel unit features a fixed NBR elastomer bumper to absorb end-of-stroke energy rather than an adjustable air cushion. The built-in magnet (-S) allows position sensing using either reed or solid-state electronic switches. If air pressure drops below the 0.2 MPa minimum or fails entirely, the spring forces the rod to its extended rest position for safe hold-down-release logic.
Airtac ATQ Single Acting Thin Cylinder ATQ63X5S Technical Specifications
| Model | Airtac ATQ Single Acting Thin Cylinder ATQ63X5S |
|---|---|
| Series | ATQ JIS compact single-acting cylinder |
| Bore size | Ø63 mm |
| Stroke | 5 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 ATQ63X5S Is Used
Gate Retraction
Pulling a heavy diverter gate closed on a packaging conveyor using the spring-extend fail-safe to release the gate when air stops.
Clamp Release
Holding a large metal casting under tension during machining, then exhausting air so the internal spring extends the rod to drop the part.
Pin Extraction
Drawing a heavy locating pin out of a stamping fixture against a 0.2 MPa minimum pressure requirement to overcome the return spring.
Is the Airtac ATQ Single Acting Thin Cylinder ATQ63X5S the Right Cylinder?
For lighter tensioning loads, the adjacent 50mm bore offers an 824.6 N theoretical pull at 0.5 MPa. If you need longer travel beyond the 30mm maximum for this 63mm bore, select a double-acting ACQ cylinder. When ordering, verify your required 5mm stroke, the 63mm bore, the -S magnet, 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 ATQ63X5S FAQ
It provides a 1401.5 N theoretical pull at 0.5 MPa and 1962.2 N at 0.7 MPa before the spring lowers net output. The single-acting spring-extend design requires a 0.2 MPa minimum air pressure, and the maximum standard stroke for a 63mm bore is 30mm.
Loss of air pressure causes the internal spring to extend the rod to its rest position. End-of-stroke energy is managed by a fixed NBR elastomer bumper, not an adjustable cushion, so external shock absorbers may be needed for high-speed loads. The -S magnet works with reed or solid-state electronic switches.
