Airtac ATQ Single Acting Thin Cylinder ATQ63X25SB
The AirTAC Airtac ATQ Single Acting Thin Cylinder ATQ63X25SB is a genuine single-acting COMPACT (JIS) cylinder (single acting, pull type) with a Ø63mm bore and 25mm 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 ATQ63X25SB
The AirTAC ATQ63X25SB is a JIS compact single-acting pull cylinder, meaning compressed air fed to its PT1/4 port retracts the Ø20 mm rod, while an internal spring drives extension upon exhaust. This fail-safe extend behavior suits mechanisms needing automatic retraction to a resting forward state during a pressure drop. The bore is 63 mm.
It delivers a theoretical pull force of 1401.5 N at 0.5 MPa and 1962.2 N at 0.7 MPa before spring resistance; verify net output from the datasheet. The 25 mm stroke fits within the 30 mm maximum limit for this bore. A fixed NBR elastomer bumper absorbs end-of-travel impact, and the -S magnet enables tracking via reed or solid-state switches.

| Stroke | 25 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 ATQ63X25SB Is Used
Web Tensioning
Applies a strong pull to maintain tension on packaging film or wire extrusion lines, with the spring ensuring a safe slack-release if air pressure is lost.
Pallet Stop Gate
Retracts a heavy physical barrier on a conveyor to let pallets pass, using the spring-extend action to lock the gate back into position as a default rest state.
Clamp Release Mechanism
Draws back a holding fixture on machining centers to free finished parts, relying on the 1962.2 N theoretical pull to overcome stubborn spring-loaded tooling.
Is the Airtac ATQ Single Acting Thin Cylinder ATQ63X25SB the Right Cylinder?
For lower force needs, the 50 mm bore offers 824.6 N theoretical pull at 0.5 MPa. If your application requires a longer travel distance beyond the 30 mm maximum, select a double-acting ACQ cylinder. To configure this model correctly, confirm the 63 mm bore, 25 mm stroke, the -S magnet, and the -B male M18x1.5 rod-end thread for direct load coupling.
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 ATQ63X25SB FAQ
The theoretical pull force is 1401.5 N at 0.5 MPa and 1962.2 N at 0.7 MPa before spring reduction; always check the datasheet for net force. It requires a 0.2 MPa minimum operating pressure to overcome the internal spring, supports a 25 mm stroke, and runs at 0.2-1.0 MPa.
The cylinder uses a fixed NBR elastomer bumper at the stroke ends for impact absorption rather than an adjustable air cushion. The included -S magnet allows position detection using either reed or electronic solid-state switches.
