Airtac ATQ Single Acting Thin Cylinder ATQ63X5B
The AirTAC Airtac ATQ Single Acting Thin Cylinder ATQ63X5B 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 ATQ63X5B
The ATQ63X5B is a JIS compact single-acting pull-type cylinder. Feeding air to the single PT1/4 port retracts the Ø20 mm rod, while an internal spring drives the extension motion upon exhaust. It delivers a theoretical pull force of 1401.5 N at 0.5 MPa and 1962.2 N at 0.7 MPa before the return spring. Because the spring counteracts the air pressure, the actual net output is lower and must be verified from the official datasheet.
This unit features a male M18x1.5 rod-end thread (-B) for direct mechanical coupling to your tensioning or hold-down-release mechanism. It uses a fixed NBR elastomer bumper at the stroke ends to soften impact rather than an adjustable air cushion. Operating pressure spans 0.2-1.0 MPa, requiring a minimum of 0.2 MPa to overcome the internal spring. The 5 mm stroke is well within the 30 mm maximum travel limit for this 63 mm bore size.
Airtac ATQ Single Acting Thin Cylinder ATQ63X5B Technical Specifications

| 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 ATQ63X5B Is Used
Tensioning Systems
Ideal for maintaining cable or belt tension in heavy material handling lines, using the spring-extend rest position to pull the rod out and release slack when air is removed.
Hold-Down Release
Secures heavy fabricated metal components during machining; supplying air pulls the rod back to clear the part for robotic unloading.
Pin Extraction
Draws locking pins out of large jigs and dies on automotive assembly floors, relying on the male M18x1.5 thread for a rigid load connection.
Is the Airtac ATQ Single Acting Thin Cylinder ATQ63X5B the Right Cylinder?
If 1401.5 N of theoretical pull at 0.5 MPa is excessive, step down to the 50 mm bore offering 824.6 N. If your application requires even greater retraction power, this 63 mm bore is the largest available in the series. The 5 mm stroke is short and precise; if your mechanism needs travel beyond 30 mm, you must switch to a double-acting ACQ cylinder. When ordering, confirm the 63 mm bore, 5 mm stroke, male M18x1.5 rod thread (-B), and note that this specific configuration ships without a 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 ATQ63X5B FAQ
It provides a theoretical pull of 1401.5 N at 0.5 MPa and 1962.2 N at 0.7 MPa before the return spring lowers the net output. The operating pressure is 0.2-1.0 MPa (0.2 MPa minimum to overcome the spring). The 5 mm stroke is within the 30 mm maximum limit for this 63 mm bore.
Loss of air pressure causes the internal spring to extend the rod to its rest position, ensuring a safe release of the load. Impact deceleration is handled by a fixed NBR elastomer bumper, not an adjustable air cushion; for high-energy approaches, slow the speed or add an external shock absorber.
