Airtac PTB Single Acting Pen-Type Cylinder PTB10X15SCB
The AirTAC Airtac PTB Single Acting Pen-Type Cylinder PTB10X15SCB is a single acting, pull type (spring extend) pen-size mini cylinder with a Ø10mm bore and 15mm 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 PTB10X15SCB
The AirTAC PTB10X15SCB is a JIS pen-size single-acting pull cylinder where air entering the M5x0.8 port retracts the rod, while an internal spring pushes it back out. It provides 23.5 N of net pull at 0.5 MPa and 36.7 N at the 0.7 MPa maximum. Because the spring constantly pushes outward, losing air pressure forces the rod into a fail-safe extended position, ideal for holding parts or returning mechanisms to a home spot.
This variant includes a built-in piston magnet for position sensing with reed or electronic switches, plus a CB double clevis back cover for pivoting loads. The slim SUS304 stainless body and fixed TPU bumper save space in tight jigs. For smooth operation, plan for a safe working load of about 14 N (roughly 60 percent of the 0.5 MPa rating) to account for seal friction.
Airtac PTB Single Acting Pen-Type Cylinder PTB10X15SCB Technical Specifications
| Model | Airtac PTB Single Acting Pen-Type Cylinder PTB10X15SCB |
|---|---|
| Series | PTB JIS pen-size mini cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Stroke | 15 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 PTB10X15SCB Is Used
Hold-Down Clamping
Uses the spring-extended rod to keep a workpiece secured, retracting only when air is applied to release the part.
Wire Belt Tensioner
Maintains steady pulling tension on a belt or wire, yielding slightly when air exhausts to absorb line shock.
Retract-To-Open Gate
Pulls a lightweight diverter gate closed via the CB clevis, defaulting to an open state on air loss for safe clearing.
Is the Airtac PTB Single Acting Pen-Type Cylinder PTB10X15SCB the Right Cylinder?
When sizing this 10 mm bore, note its 23.5 N net pull at 0.5 MPa is lower than a matching push cylinder because the powered stroke acts on the smaller rod-side area. Stepping down to a 6 mm bore yields only 7.1 N, while moving up to a 12 mm bore provides 33.1 N. The internal return spring sets a 0.2 MPa minimum pressure before motion begins.
Confirm your ordering essentials: this 15 mm stroke is well within the 60 mm limit, the rod end features an M8x1.0 thread, and the Ø4 mm rod requires an external guide if subjected to off-axis loads over long strokes.
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 PTB10X15SCB FAQ
It generates 23.5 N of net pull at 0.5 MPa and 36.7 N at the 0.7 MPa maximum. Because an internal spring holds the rod extended, a minimum of 0.2 MPa is required to overcome the spring and retract the rod.
The fixed TPU bumper only decelerates the last few millimeters of travel. At higher speeds with real tooling mass, it can bottom out, so you should meter-out the exhaust or add an external shock absorber. The built-in magnet works with reed or electronic switches.
