Airtac ATQ Single Acting Thin Cylinder ATQ63X20
The AirTAC Airtac ATQ Single Acting Thin Cylinder ATQ63X20 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 ATQ63X20
The AirTAC ATQ63X20 is a single-acting PULL-type compact cylinder where supplying air to one port retracts the rod, while an internal spring extends it upon exhaust. It delivers a robust 1401.5 N theoretical pull at 0.5 MPa and 1962.2 N at 0.7 MPa. Remember these figures represent theoretical pull before the spring; the internal return spring lowers the net output, so confirm exact net force values from the official datasheet.
Designed with a 63 mm bore and 20 mm stroke, this JIS compact unit uses a PT1/4 port and a 20 mm piston rod with a female M10x1.5 thread. It relies on a fixed NBR elastomer bumper to absorb end-of-stroke energy rather than an adjustable air cushion. If your machine needs longer travel than this 30 mm maximum single-acting limit, a double-acting ACQ is required.
Airtac ATQ Single Acting Thin Cylinder ATQ63X20 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 ATQ63X20 Is Used
Heavy Pin Extraction
Pulling large locating pins out of heavy machining fixtures when air pressure is applied to the 63 mm bore.
Gate Retraction
Withdrawing a heavy pneumatic stop gate on a packaging conveyor using the spring-extend fail-safe to clear the path.
Tension Release
Releasing tension on large web materials by retracting a 20 mm rod, letting the internal spring push the assembly back to rest.
Is the Airtac ATQ Single Acting Thin Cylinder ATQ63X20 the Right Cylinder?
When sizing this 63 mm bore unit, dropping down to the 50 mm bore drops the theoretical pull to 824.6 N at 0.5 MPa. Moving up is not possible as 63 mm is the largest in this family. If your assembly requires a stroke longer than the 30 mm maximum, you must switch to a double-acting ACQ. To order, confirm the 20 mm stroke, select the S option if you need a magnet for sensors, and specify the female M10x1.5 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 ATQ63X20 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. The spring lowers net output, so verify net force via the datasheet. Operating pressure is 0.2-1.0 MPa with a 0.2 MPa minimum to overcome the spring, and the maximum standard stroke is 30 mm.
It is a single-acting pull type, meaning 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 air cushion. For high kinetic energy loads, use an external shock absorber.
