Airtac ATQ Single Acting Thin Cylinder ATQ20X15
The AirTAC Airtac ATQ Single Acting Thin Cylinder ATQ20X15 is a genuine single-acting COMPACT (JIS) cylinder (single acting, pull type) with a Ø20mm bore and 15mm 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 ATQ20X15
The AirTAC ATQ20X15 is a JIS compact single-acting pull cylinder. Supplying air to the single port retracts the 10mm rod, while an internal spring extends it upon exhaust. This makes the powered stroke a pull motion, with a fail-safe design that extends the rod if air pressure drops below the 0.2 MPa minimum. The 20mm bore yields a theoretical pull force of 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa before spring deduction.
This 15mm stroke unit uses an M5x0.8 port and a female M5x0.8 rod-end thread. It relies on a fixed elastomer bumper for end-of-stroke impact absorption rather than an adjustable air cushion. The body includes standard magnetic-switch grooves, though this specific configuration ships without the internal magnet. The compact footprint and short travel suit tight assembly areas where tensioning or part release is the primary objective.
Airtac ATQ Single Acting Thin Cylinder ATQ20X15 Technical Specifications

| Bore size | Ø20 mm |
| Stroke | 15 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 ATQ20X15 Is Used
Pin Extraction
Pulls locating pins out of machined fixtures on automated CNC mills to allow finished part ejection.
Gate Retraction
Withdraws a pneumatic stopper gate on a packaging line to release queued cartons down the flow.
Gripper Release
Tensions a mechanical gripper closed during press cycles and springs open to drop stamped components.
Is the Airtac ATQ Single Acting Thin Cylinder ATQ20X15 the Right Cylinder?
For this 20mm bore, the theoretical pull output is 117.8 N at 0.5 MPa. If your application requires less force, the 16mm bore variant offers 75.4 N at 0.5 MPa. If more force is needed, the 25mm bore provides 188.9 N at 0.5 MPa. The 15mm stroke fits well within the 30mm maximum travel for this bore size. Should your project require longer travel, a double-acting ACQ cylinder is the correct alternative. When ordering, confirm the 20mm bore, 15mm stroke, female M5x0.8 rod thread, and whether you need the -S magnet option for sensor tracking.
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 ATQ20X15 FAQ
The theoretical pull force is 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa before spring deduction. It is a single-acting pull cylinder with a spring-extend function, requiring a 0.2 MPa minimum operating pressure. The maximum standard stroke for this 20mm bore is 30mm, and this 15mm variant operates at speeds of 50-500 mm/s.
It uses a fixed TPU elastomer bumper at the ends to absorb impact energy rather than an adjustable air cushion. The body features standard sensor grooves for mounting reed or solid-state switches, but this specific model ships without the internal magnet. If position detection is required, select the -S magnet option.
