Airtac PTB Single Acting Pen-Type Cylinder PTB10X30SR
The AirTAC Airtac PTB Single Acting Pen-Type Cylinder PTB10X30SR is a single acting, pull type (spring extend) pen-size mini cylinder with a Ø10mm bore and 30mm stroke. A single air port drives the pull stroke; the built-in return spring resets the rod when air is released, so only one solenoid line is needed.

About the Airtac PTB Single Acting Pen-Type Cylinder PTB10X30SR
The AirTAC PTB10X30SR is a JIS pen-size single-acting pull cylinder. Air entering the single M5x0.8 port retracts the Ø4 mm rod, while an internal spring pushes it back out upon exhaust release. This spring-extend design ensures the rod fails safe in the extended position during air loss, making it ideal for holding parts or returning tooling to a home state. You get 23.5 N of net pull at 0.5 MPa and 36.7 N at 0.7 MPa.
Built with a SUS304 stainless barrel and a slim body, it saves space in tight jigs. The built-in piston magnet (-S) allows position sensing with reed or electronic switches. Because pull acts on the smaller rod-side area, this output is lower than a matching push cylinder. For real-world planning, target a safe working load of roughly 14 N (about 60 percent of the 0.5 MPa figure) to account for seal friction and smooth travel.
Airtac PTB Single Acting Pen-Type Cylinder PTB10X30SR Technical Specifications
| Model | Airtac PTB Single Acting Pen-Type Cylinder PTB10X30SR |
|---|---|
| Series | PTB JIS pen-size mini cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Stroke | 30 mm |
| Acting type | Single acting, pull type (spring extend) |
| Port size | M5×0.8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.2 – 0.7 MPa |
| Proof pressure | 1.2 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 50 – 800 mm/s |
| Return | Return spring (pull by air) |
| Max standard stroke | Up to 60 mm |
The spring holds the rod extended; applying air retracts it, and removing air lets the spring push the rod back out. Forces below are the NET spring-deducted values from the AirTAC thrust table. Confirm against the product label before installation.
Net Pull Force (Ø10mm)
| Pressure | Net pull force |
|---|---|
| 0.5 MPa | 23.5 N |
| 0.7 MPa (max) | 36.7 N |
These are the usable pull forces after the return spring is subtracted, taken directly from the AirTAC single-acting thrust table. Minimum operating pressure is set by the spring, so this model needs at least the lower pressure shown to move.

Where the Airtac PTB Single Acting Pen-Type Cylinder PTB10X30SR Is Used
Hold-Down Clamping
Uses spring pressure to keep a workpiece extended and clamped, retracting only when air is applied to release the part.
Wire Belt Tensioner
Maintains constant tension on a belt or wire by default, pulling back to slacken the line when pressurized.
Retract-to-Open Gate
Spring force holds a diverter gate closed across the belt; a single air signal pulls the gate open to pass items.
Is the Airtac PTB Single Acting Pen-Type Cylinder PTB10X30SR the Right Cylinder?
This 10 mm bore provides 23.5 N net pull at 0.5 MPa. If your jig needs less force, stepping down to the Ø6 bore yields 7.1 N. If you need more pull, the Ø12 bore offers 33.1 N. The internal return spring sets a 0.2 MPa minimum pressure before motion begins. Remember that the thin Ø4 mm rod handles coaxial thrust; over this 30 mm stroke, add an external guide for any off-axis loads to prevent side loading.
The fixed TPU bumper decelerates only the last few millimeters of travel. At higher cycling speeds with real tooling mass, it can bottom out, so meter-out the exhaust or add an external shock absorber. This configuration includes the -S magnet for sensing and the R axial inlet for in-line plumbing.
Quick checklist
- ✓ Net pull force at your working pressure
- ✓ Only one air line / solenoid needed
- ✓ Fail-safe extend on air loss
- ✓ Magnet (S) for sensors?
- ✓ Stroke ≤ 60 mm (single-acting limit)
- ✓ Keep the load coaxial — avoid side load
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.2 – 0.7 MPa operating pressure.
- check Allow for spring force in the stroke direction.
- check Do not add an external return mechanism.
- check Keep the load coaxial; avoid side load on the thin rod.
- check Do not dismantle the front or back cover.
Airtac PTB Single Acting Pen-Type Cylinder PTB10X30SR FAQ
The PTB10X30SR provides 23.5 N of net pull at 0.5 MPa and 36.7 N at 0.7 MPa. Because the internal spring opposes motion, a minimum pressure of 0.2 MPa is required before the rod retracts. Upon air loss, the spring pushes the rod back out to the extended position.
Yes, the -S suffix indicates a built-in piston magnet. This allows you to mount AirTAC reed or electronic solid-state switches directly to the body for position detection. The fixed TPU bumper handles end-of-stroke deceleration.
