Airtac PTB Single Acting Pen-Type Cylinder PTB10X15SR
The AirTAC Airtac PTB Single Acting Pen-Type Cylinder PTB10X15SR 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 PTB10X15SR
The AirTAC PTB10X15SR 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. It provides 23.5 N of net pull at 0.5 MPa and 36.7 N at the 0.7 MPa maximum. Because the return spring constantly opposes the air stroke, these figures already reflect the usable force after spring deduction.
This configuration features a built-in piston magnet for position sensing alongside an axial R back cover for in-line plumbing. The slim SUS304 stainless body incorporates a fixed TPU bumper at each end to decelerate the last few millimeters of travel. 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 and smooth motion.
Airtac PTB Single Acting Pen-Type Cylinder PTB10X15SR Technical Specifications
| Model | Airtac PTB Single Acting Pen-Type Cylinder PTB10X15SR |
|---|---|
| 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 PTB10X15SR Is Used
Hold-Down Clamp
Uses spring pressure to keep a workpiece extended safely, applying 23.5 N of pulling force at 0.5 MPa to secure parts during light machining.
Wire Tensioner
Maintains constant tension on filaments or belts by defaulting to the extended position, retracting only when 0.2 MPa air pressure is applied.
Retract-to-Open Gate
Diverts packages on a line by pulling a guide inward; the spring automatically pushes the guide back out to block flow if the air supply drops.
Is the Airtac PTB Single Acting Pen-Type Cylinder PTB10X15SR the Right Cylinder?
When sizing this 10 mm bore actuator, compare its 23.5 N net pull at 0.5 MPa against adjacent options. Dropping down to the 6 mm bore yields only 7.1 N, whereas stepping up to the 12 mm bore provides 33.1 N. Choose this model when your mechanism requires moderate pulling force within a compact footprint. Remember the internal spring sets a 0.2 MPa minimum pressure before motion begins, and the rod is fail-safe extended upon air loss.
Confirm your ordering essentials: the 15 mm stroke sits well below the 60 mm single-acting limit, and the -S suffix enables use with reed or electronic switches. The slender 4 mm rod handles coaxial thrust well, but over this stroke or under off-axis loads you should add an external guide or linear bearing 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 PTB10X15SR 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 holds the rod extended, a minimum pressure of 0.2 MPa is required before the air can overcome the spring to retract the rod.
The -S suffix indicates a built-in piston magnet compatible with reed or electronic switches. The fixed TPU bumper at each end only decelerates the last few millimeters of travel; at higher speeds with real tooling mass, meter-out the exhaust or add an external shock absorber.
