Airtac PTB Single Acting Pen-Type Cylinder PTB10X10CB
The AirTAC Airtac PTB Single Acting Pen-Type Cylinder PTB10X10CB is a single acting, pull type (spring extend) pen-size mini cylinder with a Ø10mm 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 PTB10X10CB
The AirTAC PTB10X10CB is a JIS pen-size single-acting pull cylinder where air entering the 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 0.7 MPa. The CB double clevis allows pivoting on a pin, while the SUS304 stainless barrel and slim body fit light end-of-arm tooling.
Because the return spring constantly opposes the air stroke, plan for a safe working load of roughly 14 N to account for seal friction. If lifting a part vertically, this actuator handles about 1.2 kg with a 2:1 safety margin. The fixed TPU bumper decelerates the last few millimeters of travel, but at high speeds with real tooling mass, you should meter-out the exhaust or add an external shock absorber.
Airtac PTB Single Acting Pen-Type Cylinder PTB10X10CB Technical Specifications
| Model | Airtac PTB Single Acting Pen-Type Cylinder PTB10X10CB |
|---|---|
| Series | PTB JIS pen-size mini cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 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 (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 PTB10X10CB Is Used
Pivoting Hold-Down Clamp
Uses the CB clevis to swing and clamp parts securely, relying on the spring to safely lift the rod out of the way when air is removed.
Wire Belt Tensioner
Applies steady pulling tension on moving lines, automatically releasing the pull back to a safe extended position during an air loss event.
Retract-to-Open Gate
Pulls a light diverter gate closed to sort items, letting the internal spring instantly push the gate open when the single solenoid stops.
Is the Airtac PTB Single Acting Pen-Type Cylinder PTB10X10CB the Right Cylinder?
This 10 mm bore yields 23.5 N 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. A minimum pressure of 0.2 MPa is required to overcome the spring before motion starts. Without live air, the spring holds the rod extended, making it fail-safe for hold-down or return-to-home tasks.
The Ø4 mm piston rod is built for coaxial thrust, so over the 10 mm stroke or under off-axis loads, add an external guide or linear bearing to prevent side loading. This configuration includes a CB double clevis and no sensor magnet.
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 PTB10X10CB FAQ
The net pull force is 23.5 N at 0.5 MPa and 36.7 N at 0.7 MPa. Because an internal spring holds the rod extended, a minimum of 0.2 MPa is required before air can retract the piston.
The CB back cover is a double clevis for pivoting mounts. It uses a fixed TPU bumper to soften the last few millimeters of travel; for heavy tooling at high speeds, meter-out the exhaust or add an external shock absorber.
