Airtac PTB Single Acting Pen-Type Cylinder PTB12X10R
The AirTAC Airtac PTB Single Acting Pen-Type Cylinder PTB12X10R is a single acting, pull type (spring extend) pen-size mini cylinder with a Ø12mm bore and 10mm 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 PTB12X10R
The AirTAC PTB12X10R is a JIS pen-size single-acting pull cylinder. Air entering the M5x0.8 port retracts the Ø5 mm rod, while an internal spring pushes it back out. This spring-extend design ensures the rod stays safely extended if air pressure drops. It yields a usable 33.1 N net pull at 0.5 MPa.
Built with a SUS304 stainless barrel and a slim mini body, it fits tight jigs and light end-of-arm tooling. The fixed TPU bumper decelerates the stroke at both ends. Because pulling acts on the rod-side annular area, output is lower than a matching push cylinder, making correct sizing essential.
Airtac PTB Single Acting Pen-Type Cylinder PTB12X10R Technical Specifications
| Model | Airtac PTB Single Acting Pen-Type Cylinder PTB12X10R |
|---|---|
| Series | PTB JIS pen-size mini cylinder |
| Bore size | Ø12 mm |
| Rod diameter | Ø5 mm |
| Stroke | 10 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 (Ø12mm)
| Pressure | Net pull force |
|---|---|
| 0.5 MPa | 33.1 N |
| 0.7 MPa (max) | 51.8 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 PTB12X10R Is Used
Hold-Down Clamping
Keeps a workpiece clamped under spring pressure. Air retracts the pin to release the part, saving energy during idle cycles.
Wire Tensioning
Maintains steady tension on a wire or belt. The spring constantly pulls back, while air releases the tension on command.
Retract-to-Open Gate
Holds a small diverter gate open by default. Applying air pulls the actuator back to close the path securely.
Is the Airtac PTB Single Acting Pen-Type Cylinder PTB12X10R the Right Cylinder?
This 12 mm bore provides 33.1 N net pull at 0.5 MPa and 51.8 N at 0.7 MPa. If your task needs less force, the Ø10 bore offers 23.5 N at 0.5 MPa; for heavier pulling, the Ø16 bore provides 65.0 N. Plan for a safe working load of about 20 N, which is roughly 60 percent of the 0.5 MPa rating, to account for seal friction.
The internal return spring demands a minimum 0.2 MPa to overcome its resistance and move the rod. This configuration includes the R axial back cover for inline plumbing. It lacks a sensor magnet, so position detection is unavailable.
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 PTB12X10R FAQ
The net pull force is 33.1 N at 0.5 MPa and 51.8 N at 0.7 MPa. Because an internal spring extends the rod, a minimum air pressure of 0.2 MPa is required to overcome the spring and retract the piston.
It uses a fixed TPU bumper at each end to decelerate the stroke over the last few millimeters. It is not adjustable. If you move real tooling mass at high speeds, meter-out the exhaust or add an external shock absorber to prevent bottoming out.
