Airtac ATQ Single Acting Thin Cylinder ATQ20X5SB
The AirTAC Airtac ATQ Single Acting Thin Cylinder ATQ20X5SB is a genuine single-acting COMPACT (JIS) cylinder (single acting, pull type) with a Ø20mm 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 ATQ20X5SB
The AirTAC ATQ20X5SB is a single-acting pull-type JIS compact cylinder where compressed air fed to its M5x0.8 port retracts the 10mm rod, while an internal spring extends it upon exhaust. This fail-safe extend behavior naturally suits hold-down-release and tensioning logic. Theoretical pull force is 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa, though the return spring lowers net output, which you should confirm from the datasheet.
This configuration includes a male M8x1.25 rod-end thread (-B) for direct load coupling and a built-in magnet (-S) for tracking with reed or solid-state switches. It uses a fixed TPU elastomer bumper at each end rather than an adjustable air cushion, and its 5mm stroke stays well under the 30mm maximum travel allowed for this 20mm bore.
Airtac ATQ Single Acting Thin Cylinder ATQ20X5SB Technical Specifications
| Model | Airtac ATQ Single Acting Thin Cylinder ATQ20X5SB |
|---|---|
| Series | ATQ JIS compact single-acting cylinder |
| Bore size | Ø20 mm |
| Stroke | 5 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 ATQ20X5SB Is Used
Pin Extraction Jig
Applies air-driven retraction to pull a locating pin out of a clamped fixture, letting the internal spring safely extend it back to a resting hold position.
Package Stopper Release
Retracts a gating stop on a packaging conveyor to release cartons, relying on the spring-extend fail-safe to block the next item if air pressure drops.
Gripper Tensioning Arm
Draws a mechanical gripper closed on delicate electronics using the male M8 thread, exhausting air to let the spring open the jaws safely.
Is the Airtac ATQ Single Acting Thin Cylinder ATQ20X5SB the Right Cylinder?
For a 20mm bore, theoretical pull is 117.8 N at 0.5 MPa. Stepping down to a 16mm bore drops the theoretical pull to 75.4 N, while moving up to a 25mm bore raises it to 188.9 N. If your application needs longer travel beyond the 30mm single-acting limit, consider a double-acting ACQ cylinder. To order this pull-type unit correctly, verify the 20mm bore, 5mm stroke, -S magnet, and -B male 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 ATQ20X5SB FAQ
Theoretical pull is 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa before spring deduction; operating pressure is 0.2-1.0 MPa with a 0.2 MPa minimum to overcome the spring. It is a single-acting pull type with spring extend, and the 5mm stroke is under the 30mm max for this 20mm bore.
Loss of air pressure causes the internal spring to extend the rod to its rest position. End-of-stroke energy is absorbed by a fixed TPU elastomer bumper, not an adjustable air cushion, so high-speed applications may need external shock absorption.
