Airtac PTB Single Acting Pen-Type Cylinder PTB10X15CB
The AirTAC Airtac PTB Single Acting Pen-Type Cylinder PTB10X15CB 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 PTB10X15CB
The AirTAC PTB10X15CB is a JIS pen-size single-acting pull cylinder with a 10 mm bore and 15 mm stroke. A built-in spring holds the rod extended, while supplying air to the single M5x0.8 port retracts it. This fail-safe extended state is ideal for holding or returning mechanisms when air pressure drops. The CB double clevis back cover accommodates pivoting mountings.
Because the powered stroke pulls against the rod-side annular area, the usable force is lower than a matching push cylinder. This model yields a 23.5 N net pull at 0.5 MPa and 36.7 N at 0.7 MPa. The SUS304 stainless build and fixed TPU bumper ensure durability in tight jigs. Plan for a safe working load of roughly 14 N to account for friction and smooth travel.
Airtac PTB Single Acting Pen-Type Cylinder PTB10X15CB Technical Specifications
| Model | Airtac PTB Single Acting Pen-Type Cylinder PTB10X15CB |
|---|---|
| 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 PTB10X15CB Is Used
Pivoting Hold-Down Clamp
Uses the CB clevis to swing down and grip parts. The spring-extend design ensures the clamp releases upward safely if air pressure is lost.
Wire Belt Tensioner
Maintains consistent tension on moving lines. The single air line retracts the rod to adjust slack, while the spring provides a steady extended pull.
Retract-To-Open Gate
Pulls a lightweight diverter gate closed during operation. Air exhaustion lets the spring push the gate open, defaulting to a safe open state.
Is the Airtac PTB Single Acting Pen-Type Cylinder PTB10X15CB the Right Cylinder?
Select this 10 mm bore actuator when you need a compact pull force of 23.5 N at 0.5 MPa. If your application requires less force, the 6 mm variant offers 7.1 N, while stepping up to the 12 mm bore provides 33.1 N. The internal return spring demands a minimum 0.2 MPa operating pressure before motion begins, and the rod safely extends outward upon air loss.
Confirm the 15 mm stroke meets your travel requirement, as single-acting versions cap at 60 mm. This configuration includes a CB double clevis for pivoting loads and lacks a sensor magnet. The M8x1.0 rod-end thread and M5x0.8 air port simplify integration into existing pneumatic setups.
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 PTB10X15CB FAQ
It provides a 23.5 N net pull at 0.5 MPa and 36.7 N at 0.7 MPa. The internal spring requires a minimum 0.2 MPa to initiate retraction, and the rod fails safe to the extended position upon air loss.
The fixed TPU bumper decelerates the rod over the last few millimeters but cannot stop heavy masses at high speeds; meter-out the exhaust or add an external shock absorber if needed. The 4 mm rod is built for coaxial thrust, so use an external guide to prevent side-loading damage.
