Airtac PTB Single Acting Pen-Type Cylinder PTB10X15R
The AirTAC Airtac PTB Single Acting Pen-Type Cylinder PTB10X15R 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 PTB10X15R
The AirTAC PTB10X15R is a JIS pen-size single-acting pull cylinder where air entering one M5x0.8 port retracts the rod, while an internal spring pushes it back out. It provides a usable net pull of 23.5 N at 0.5 MPa and 36.7 N at the 0.7 MPa maximum. The slim SUS304 stainless body saves space in tight jigs, and the fixed TPU bumper cushions the stroke ends.
Because the return spring constantly opposes the air stroke, a minimum 0.2 MPa is required before motion begins. If pneumatic pressure drops, the spring ensures the rod fails safe in the extended position. Plan for a safe working load of about 14 N, which accounts for friction and smooth travel.
Airtac PTB Single Acting Pen-Type Cylinder PTB10X15R Technical Specifications
| Model | Airtac PTB Single Acting Pen-Type Cylinder PTB10X15R |
|---|---|
| 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 PTB10X15R Is Used
Hold-Down Clamp
Uses spring pressure to keep a workpiece extended, then retracts to release the part for machining.
Wire Tensioner
Maintains constant outward tension on a filament or belt, pulling back only when air is applied.
Retract-to-Open Gate
Blocks a conveyor lane by default and pulls the gate open to divert parts upon actuation.
Is the Airtac PTB Single Acting Pen-Type Cylinder PTB10X15R the Right Cylinder?
This 10 mm bore generates 23.5 N of net pull at 0.5 MPa. If your task needs less force, the 6 mm bore offers 7.1 N; stepping up to the 12 mm bore provides 33.1 N. The R suffix specifies an axial inline air inlet, simplifying hose routing alongside the M8x1.0 rod-end thread.
Remember the internal spring sets a minimum 0.2 MPa operating pressure to overcome its bias. The thin 4 mm rod handles coaxial thrust well, but over this 15 mm stroke you should add an external guide for any off-axis loads to prevent side loading.
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 PTB10X15R FAQ
It delivers a net pull of 23.5 N at 0.5 MPa and 36.7 N at the 0.7 MPa maximum. Because an internal spring holds the rod extended, a minimum 0.2 MPa air pressure is needed to overcome the spring and retract the rod.
Air drives the powered retraction stroke, while the spring handles the extension. A fixed TPU bumper decelerates the rod at the end of travel, but with heavy tooling mass at higher speeds you should meter-out the exhaust or add an external shock absorber.
