Airtac ATQ Single Acting Thin Cylinder ATQ40X15B
The AirTAC Airtac ATQ Single Acting Thin Cylinder ATQ40X15B is a genuine single-acting COMPACT (JIS) cylinder (single acting, pull type) with a Ø40mm 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 ATQ40X15B
The ATQ40X15B is a JIS compact single-acting pull cylinder where supplying air to the single PT1/8 port retracts the Ø16 mm rod, while an internal spring drives extension upon exhaust. This fail-safe behavior ensures the rod extends to its rest position if air pressure drops, suiting hold-down-release or tensioning workflows. It delivers a theoretical pull of 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa before spring deduction; verify the net output via the datasheet.
This 40 mm bore variant features a 15 mm stroke and a male M14x1.5 rod end that couples directly to your load. Travel is capped at 30 mm for this bore size, and the body incorporates fixed NBR elastomer bumpers to soften end-of-stroke impacts rather than adjustable air cushions. Although the body retains magnetic-switch grooves, this specific SKU ships without a piston magnet.
Airtac ATQ Single Acting Thin Cylinder ATQ40X15B Technical Specifications
| Model | Airtac ATQ Single Acting Thin Cylinder ATQ40X15B |
|---|---|
| Series | ATQ JIS compact single-acting cylinder |
| Bore size | Ø40 mm |
| Stroke | 15 mm |
| Acting type | Single acting, pull type |
| Port size | PT1/8 |
| Rod end thread | M8×1.25 female / M14×1.5 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 (Ø40mm, Pull)
| Pressure | Pull force (before spring) |
|---|---|
| 0.5 MPa | 528 N |
| 0.7 MPa | 739 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 ATQ40X15B Is Used
Clamp Release Mechanism
Uses the spring-extend fail-safe to automatically open a machining fixture and release a finished metal part when compressed air is cut off.
Diverter Gate Retraction
Pulls a sorting gate out of the product flow on a packaging line, relying on the 527.8 N theoretical pull to overcome guide friction.
Tensioning Pullback
Draws back a tensioning pulley on an automated textile machine, using the male M14x1.5 thread for a direct rigid linkage.
Is the Airtac ATQ Single Acting Thin Cylinder ATQ40X15B the Right Cylinder?
For sizing context, dropping to a 32 mm bore reduces the theoretical pull to 301.6 N at 0.5 MPa, while stepping up to a 50 mm bore raises it to 824.6 N at 0.5 MPa. If your mechanism needs travel beyond 30 mm, switch to the double-acting ACQ series. When ordering this pull-type unit, confirm the 40 mm bore, 15 mm stroke, male M14x1.5 rod thread, and whether your application requires adding an S-suffix magnet for reed or solid-state sensors.
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 ATQ40X15B FAQ
It provides a theoretical pull of 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa before spring deduction. It is a single-acting pull type requiring a 0.2 MPa minimum operating pressure to overcome the spring, with a maximum standard stroke of 30 mm for this 40 mm bore.
It uses fixed NBR elastomer bumpers at the ends to absorb impact rather than adjustable air cushions. The body features grooves for reed or solid-state switches, but this specific model lacks the internal piston magnet, so external sensors will not detect position without modification.
