Airtac ATQ Single Acting Thin Cylinder ATQ25X30SB
The AirTAC Airtac ATQ Single Acting Thin Cylinder ATQ25X30SB is a genuine single-acting COMPACT (JIS) cylinder (single acting, pull type) with a Ø25mm bore and 30mm 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 ATQ25X30SB
The AirTAC ATQ25X30SB is a single-acting pull-type JIS compact cylinder. Feeding air to the single M5x0.8 port retracts the 12mm rod, while an internal spring drives extension upon exhaust. It yields a theoretical pull of 188.9N at 0.5MPa and 264.5N at 0.7MPa before the return spring lowers net output, which you should verify via the datasheet.
This 25mm bore unit features a 30mm stroke, hitting the maximum standard travel for this size. It includes a fixed TPU elastomer bumper to manage end-of-stroke energy rather than an adjustable air cushion. Equipped with both the -S magnet and -B male M10x1.25 rod-end thread, it couples directly to loads and supports reed or solid-state electronic sensing.
Airtac ATQ Single Acting Thin Cylinder ATQ25X30SB Technical Specifications
| Model | Airtac ATQ Single Acting Thin Cylinder ATQ25X30SB |
|---|---|
| Series | ATQ JIS compact single-acting cylinder |
| Bore size | Ø25 mm |
| Stroke | 30 mm |
| Acting type | Single acting, pull type |
| Port size | M5×0.8 |
| Rod end thread | M6×1.0 female / M10×1.25 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 (Ø25mm, Pull)
| Pressure | Pull force (before spring) |
|---|---|
| 0.5 MPa | 189 N |
| 0.7 MPa | 264 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 ATQ25X30SB Is Used
Withdraw a Locator Pin
Powers the retraction of a 12mm rod to pull a定位 pin out of an assembly fixture, using the internal spring to extend it back into position during air loss.
Retract a Package Stop
Utilizes the 264.5N theoretical pull at 0.7MPa to retract a conveyor gating arm out of the product path, allowing boxed goods to pass freely.
Tension a Clamping Belt
Draws a male M10x1.25 threaded fixture backward to maintain belt tension on a packaging machine, releasing tension safely when air is removed.
Is the Airtac ATQ Single Acting Thin Cylinder ATQ25X30SB the Right Cylinder?
If you need less retraction force, step down to the 20mm bore providing 117.8N theoretical pull at 0.5MPa. For heavier pulling, move up to the 32mm bore yielding 301.6N at 0.5MPa. Travel is capped at 30mm for single-acting pull types; longer reach requires the double-acting ACQ series. When ordering, confirm the 25mm bore, 30mm stroke, -S magnet, and -B male M10x1.25 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 ATQ25X30SB FAQ
It provides a theoretical pull of 188.9N at 0.5MPa and 264.5N at 0.7MPa before the return spring lowers the net output. It requires a minimum operating pressure of 0.2MPa to overcome the spring, and the 30mm stroke is the maximum standard travel for this 25mm bore.
Loss of air pressure causes the internal spring to extend the rod to its resting position. The -S magnet enables position detection using either reed or solid-state electronic switches, and the fixed TPU bumper absorbs impact at stroke ends without external adjustment.
