Airtac ATQ Single Acting Thin Cylinder ATQ50X5SB
The AirTAC Airtac ATQ Single Acting Thin Cylinder ATQ50X5SB is a genuine single-acting COMPACT (JIS) cylinder (single acting, pull type) with a Ø50mm bore and 5mm 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 ATQ50X5SB
The ATQ50X5SB is a JIS compact cylinder configured for single-acting PULL operation. Supplying air to its single PT1/4 port retracts the 20mm piston rod, while an internal mechanical spring drives the extension stroke upon venting. This unit delivers a theoretical pull force of 824.6N at 0.5MPa and 1154.5N at 0.7MPa before spring resistance; verify the exact net output via the official datasheet.
This specific configuration includes an -S piston magnet for position sensing and a -B male M18x1.5 rod-end thread for direct load coupling. It features a fixed NBR elastomer bumper at the ends to soften end-of-trroke impacts rather than an adjustable air cushion. Operating pressure spans 0.2-1.0MPa, requiring a 0.2MPa minimum to overcome the return mechanism.
Airtac ATQ Single Acting Thin Cylinder ATQ50X5SB Technical Specifications

| Bore size | Ø50 mm |
| Stroke | 5 mm |
| Acting type | Single acting, pull type |
| Port size | PT1/4 |
| Rod end thread | M10×1.5 female / M18×1.5 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 (Ø50mm, Pull)
| Pressure | Pull force (before spring) |
|---|---|
| 0.5 MPa | 825 N |
| 0.7 MPa | 1155 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 ATQ50X5SB Is Used
Pin Extraction
Retracts a 20mm rod to withdraw locating pins in heavy fabrication jigs, relying on 824.6N of theoretical 0.5MPa pull force to release the part.
Gate Retraction
Pulls a diverter gate closed on a packaging line, using the spring-extend fail-safe to automatically open the passage if compressed air is lost.
Tension Release
Draws back a tensioning clamp on a web handling machine, where the short 5mm stroke and male M18x1.5 thread provide precise take-up adjustment.
Is the Airtac ATQ Single Acting Thin Cylinder ATQ50X5SB the Right Cylinder?
For sizing context, scaling down to a 40mm bore drops the theoretical 0.5MPa pull to 527.8N, whereas stepping up to 63mm raises it to 1401.5N. This 5mm stroke is well within the 30mm maximum for this bore size. If an application demands longer travel than 30mm, a double-acting ACQ series cylinder is required. Confirm ordering essentials: 50mm bore, 5mm stroke, -S magnet for electronic or reed switches, and -B male M18x1.5 rod 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 ATQ50X5SB FAQ
It is a single-acting pull cylinder with a 5mm stroke and 30mm maximum standard stroke limit. Theoretical pull is 824.6N at 0.5MPa and 1154.5N at 0.7MPa before spring reduction. It requires a 0.2MPa minimum operating pressure to function.
Loss of air pressure causes the internal spring to extend the rod to its resting position, ideal for hold-down-release logic. End-of-stroke energy is managed by a fixed NBR elastomer bumper, not an adjustable air cushion. The -S magnet allows tracking with either reed or solid-state switches.
