Airtac PTB Single Acting Pen-Type Cylinder PTB10X30CB
The AirTAC Airtac PTB Single Acting Pen-Type Cylinder PTB10X30CB 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 PTB10X30CB
The AirTAC PTB10X30CB is a JIS pen-size mini cylinder built for single-acting pull operation. Air entering the single M5x0.8 port retracts the Ø4 mm rod, while an internal spring pushes it back out upon exhaust release. This fail-safe extended state ensures your tooling returns home if air pressure drops. You get 23.5 N of net pull at 0.5 MPa, with the return spring force already deducted.
Featuring a SUS304 stainless barrel and a CB double clevis back cover, this unit handles pivoting loads easily. The slim body saves space on tight jigs. A fixed TPU bumper decelerates the stroke near the ends. Plan for a safe working load of roughly 14 N to account for seal friction and smooth travel.
Airtac PTB Single Acting Pen-Type Cylinder PTB10X30CB Technical Specifications
| Model | Airtac PTB Single Acting Pen-Type Cylinder PTB10X30CB |
|---|---|
| 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 PTB10X30CB Is Used
Pivoting Hold-Down Clamp
Uses the CB clevis to swing clear of a part; air pulls the rod back to release, and the spring failsafe extends to clamp securely.
Wire Belt Tensioner
Applies steady tension by pulling back on a belt run; the spring maintains tension automatically when shop air is removed.
Retract-to-Open Gate
Air retracts the rod to pull a lightweight diverter gate open, letting the spring push it closed as a safe default state.
Is the Airtac PTB Single Acting Pen-Type Cylinder PTB10X30CB the Right Cylinder?
When sizing this 10 mm bore option, compare it to the 6 mm variant offering 7.1 N, or step up to the 12 mm bore providing 33.1 N of net pull at 0.5 MPa. The internal return spring demands a minimum 0.2 MPa operating pressure before the rod will move. Without live air, the spring reliably holds the rod extended.
The CB double clevis mount is ideal for applications requiring a pivoting articulation. The rod-end thread is M8x1.0. Because the rod is only 4 mm thick, avoid side loads and add an external linear bearing for off-axis forces.
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 PTB10X30CB FAQ
The net pull force is 23.5 N at 0.5 MPa and 36.7 N at the 0.7 MPa maximum. The internal spring sets a 0.2 MPa minimum pressure before motion begins. If air is lost, the spring forces the rod into the extended position.
A fixed TPU bumper at each end absorbs impact over the final few millimeters of travel. Because it is not adjustable, you should meter-out the exhaust or add an external shock absorber when cycling real tooling mass at higher speeds. The spring handles the full extend stroke automatically.
