Airtac ATQ Single Acting Thin Cylinder ATQ20X30B
The AirTAC Airtac ATQ Single Acting Thin Cylinder ATQ20X30B is a genuine single-acting COMPACT (JIS) cylinder (single acting, pull type) with a Ø20mm 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 ATQ20X30B
The AirTAC ATQ20X30B is a single-acting PULL-type compact cylinder where pressurized air retracts the 10mm rod, while an internal spring extends it upon exhaust. At 0.5 MPa it provides a 117.8 N theoretical pull force (164.9 N at 0.7 MPa) before the return spring's resistance is factored in. You must confirm the net output from the datasheet, as the spring lowers the usable force.
This JIS-format actuator features a male M8x1.25 rod-end thread (-B) for direct load coupling and uses an M5x0.8 port. It incorporates a fixed TPU elastomer bumper at the stroke ends rather than an adjustable air cushion. Because it lacks the -S suffix, it ships without a sensor magnet, though the body retains magnetic-switch grooves for future automation upgrades.

| Bore size | Ø20 mm |
| Stroke | 30 mm |
| Acting type | Single acting, pull type |
| Port size | M5×0.8 |
| Rod end thread | M5×0.8 female / M8×1.25 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 (Ø20mm, Pull)
| Pressure | Pull force (before spring) |
|---|---|
| 0.5 MPa | 118 N |
| 0.7 MPa | 165 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 ATQ20X30B Is Used
Gripper Retraction
Pulls a mechanical gripper closed on metal components during CNC loading, using the spring to safely release the part when air is cut.
Diverter Arm Pull
Retracts a sorting gate stop on a packaging line; the spring automatically extends the barrier to halt product flow during pressure loss.
Pin Extraction
Draws a locating pin out of a fixture on a warehouse pallet system, ensuring the pin protrudes to secure the pallet when unpowered.
Is the Airtac ATQ Single Acting Thin Cylinder ATQ20X30B the Right Cylinder?
If 117.8 N of theoretical pull is insufficient, step up to the 25 mm bore (188.9 N at 0.5 MPa); if you need less force, the 16 mm bore offers 75.4 N. This 20 mm bore is capped at a 30 mm maximum stroke for single-acting use; any longer travel requires shifting to the double-acting ACQ series. When ordering, verify the 30 mm stroke limit, the male M8x1.25 rod thread, and the lack of a magnet on this specific configuration.
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 ATQ20X30B FAQ
It has a 30 mm stroke (the maximum for a 20 mm bore). The theoretical pull is 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa before the return spring. It requires a minimum 0.2 MPa operating pressure to overcome the spring, and the spring extends the rod when air is exhausted.
It relies on a fixed TPU elastomer bumper at each end to absorb impact, not an adjustable air cushion. For high-speed loads, external shock absorbers are recommended. This model lacks a -S magnet, so it cannot trigger reed or solid-state switches, though the body has grooves for adding a magnetized version later.
