Airtac PTB Single Acting Pen-Type Cylinder PTB10X5SCB
The AirTAC Airtac PTB Single Acting Pen-Type Cylinder PTB10X5SCB is a single acting, pull type (spring extend) pen-size mini cylinder with a Ø10mm bore and 5mm 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 PTB10X5SCB
The AirTAC PTB10X5SCB is a JIS pen-size single-acting pull cylinder where air entering the single M5x0.8 port retracts the rod, and an internal spring pushes it back out upon exhaust. This fail-safe extended state is ideal for holding parts when air pressure drops. It yields a 23.5 N net pull at 0.5 MPa and 36.7 N at 0.7 MPa, with the return spring force already subtracted.
Built with a SUS304 stainless barrel and a slim Ø4 mm rod, this variant includes a built-in magnet for position sensing and a CB double clevis for pivoting loads. The fixed TPU bumper decelerates the stroke near the ends, but with heavy tooling mass at higher speeds, adding an external shock absorber is advised. Because the rod is only 4 mm thick, use an external guide to prevent side-loading damage.
Airtac PTB Single Acting Pen-Type Cylinder PTB10X5SCB Technical Specifications
| Model | Airtac PTB Single Acting Pen-Type Cylinder PTB10X5SCB |
|---|---|
| Series | PTB JIS pen-size mini cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Stroke | 5 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 PTB10X5SCB Is Used
Fail-Safe Hold-Down Clamp
Keeps a workpiece clamped by spring pressure during an air loss event, using the 5 mm stroke to retract and release only when pressurized air is applied.
Pivoting Wire Tensioner
Uses the CB double clevis to pivot naturally while maintaining steady tension on a belt or wire, retracting the 4 mm rod to slacken the line on demand.
Retract-to-Open Gate
Holds a small diverting gate closed via spring force on a conveyor line, pulling the gate open only when the single air line is energized.
Is the Airtac PTB Single Acting Pen-Type Cylinder PTB10X5SCB the Right Cylinder?
This 10 mm bore generates 23.5 N of usable pull at 0.5 MPa. If your task needs less force, the Ø6 bore offers 7.1 N; stepping up to the Ø12 provides 33.1 N. Plan for a safe working load of roughly 14 N, which is about 60 percent of the 0.5 MPa rating, to account for seal friction. For vertical lifts, expect it to securely pull or hold around 1.2 kg with a 2:1 safety margin.
Remember the internal spring requires a minimum 0.2 MPa of pressure to overcome before retraction begins. The CB double clevis accommodates angular movement, and the integrated magnet supports reed or electronic switches. Confirm your port size is M5x0.8 and the rod-end thread is M8x1.0 before finalizing the build.
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 PTB10X5SCB FAQ
The net pull force is 23.5 N at 0.5 MPa and 36.7 N at the 0.7 MPa maximum. Because an internal spring constantly pushes the rod out, a minimum of 0.2 MPa is required before the cylinder can retract the rod.
The fixed TPU bumper cushions the last few millimeters of travel but is not adjustable, so meter-out the exhaust if moving heavy tooling. The built-in magnet allows you to track rod position using reed or electronic switches.
