Airtac ATQ Single Acting Thin Cylinder ATQ16X20S
The AirTAC Airtac ATQ Single Acting Thin Cylinder ATQ16X20S is a genuine single-acting COMPACT (JIS) cylinder (single acting, pull type) with a Ø16mm 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 ATQ16X20S
The AirTAC ATQ16X20S is a JIS compact single-acting PULL cylinder where supplying air to one M5x0.8 port retracts the Ø8 mm rod, while an internal spring extends it upon exhaust. This fail-safe extend behavior naturally suits hold-down-release or tensioning logic. Theoretical pull force is 75.4 N at 0.5 MPa and 105.6 N at 0.7 MPa before the return spring lowers net output, which you should confirm from the datasheet.
Featuring a built-in magnet (-S suffix), the body integrates seamlessly with reed or electronic solid-state switches via its magnetic grooves. A fixed TPU elastomer bumper manages end-of-stroke energy instead of an adjustable air cushion. Operating pressure spans 0.2-1.0 MPa, needing 0.2 MPa minimum to overcome the spring, and this 20 mm stroke represents the maximum standard travel for a 16 mm bore.
Airtac ATQ Single Acting Thin Cylinder ATQ16X20S Technical Specifications

| Bore size | Ø16 mm |
| Stroke | 20 mm |
| Acting type | Single acting, pull type |
| Port size | M5×0.8 |
| Rod end thread | M4×0.7 female / M6×1.0 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 20 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 (Ø16mm, Pull)
| Pressure | Pull force (before spring) |
|---|---|
| 0.5 MPa | 75 N |
| 0.7 MPa | 106 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 ATQ16X20S Is Used
Pin Extraction
Uses the powered retract stroke to pull a locating pin on a packaging machine, allowing the spring to safely extend the pin back out when air is removed.
Gate Retraction
Draws back a sorting gate on a conveyor line; the spring-extend fail-safe ensures the gate opens fully if the compressed air supply drops.
Gripper Release
Pulls a small mechanical gripper closed during operation, relying on the internal spring to automatically open the jaws upon exhaust.
Is the Airtac ATQ Single Acting Thin Cylinder ATQ16X20S the Right Cylinder?
For sizing within the 12-63 mm range, stepping down to the 12 mm bore yields a 42.4 N theoretical pull at 0.5 MPa, while stepping up to the 20 mm bore provides 117.8 N at 0.5 MPa. Since 20 mm is the maximum standard stroke for this 16 mm bore, any application requiring longer travel must use a double-acting ACQ cylinder. When ordering, verify the 16 mm bore, 20 mm stroke, -S magnet option, and default female M4x0.7 rod-end thread.
Quick checklist
- ✓ Net pull force (after spring) at your pressure
- ✓ Stroke ≤ 20 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 ATQ16X20S FAQ
It provides a theoretical pull force of 75.4 N at 0.5 MPa and 105.6 N at 0.7 MPa before the spring lowers net output. It requires a 0.2 MPa minimum operating pressure to overcome the internal spring, and this 20 mm stroke is the maximum standard travel for a 16 mm bore single-acting pull cylinder.
Loss of air pressure causes the internal spring to extend the rod to its rest position, making it ideal for tensioning or release logic. End-of-stroke energy is managed by a fixed TPU elastomer bumper rather than an adjustable air cushion, and the -S magnet works with reed or electronic solid-state switches.
