Airtac PTB Single Acting Pen-Type Cylinder PTB10X5R
The AirTAC Airtac PTB Single Acting Pen-Type Cylinder PTB10X5R is a single acting, pull type (spring extend) pen-size mini cylinder with a Ø10mm bore and 5mm 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 PTB10X5R
The AirTAC PTB10X5R 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 (36.7 N at 0.7 MPa), with the return spring force already subtracted from these figures. Because the powered stroke pulls against the smaller rod-side area, this output is naturally lower than a same-bore push cylinder.
The slim SUS304 stainless body saves space on tight jigs, while the fixed TPU bumper cushions the stroke ends. If air pressure drops, the spring forces the rod into the extended position, creating a fail-safe out state for hold-down or return-to-home tasks. Plan for a safe working load of about 14 N, which accounts for friction and smooth travel.
Airtac PTB Single Acting Pen-Type Cylinder PTB10X5R Technical Specifications
| Model | Airtac PTB Single Acting Pen-Type Cylinder PTB10X5R |
|---|---|
| Series | PTB JIS pen-size mini cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Stroke | 5 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 PTB10X5R Is Used
Micro Hold-Down Clamp
Uses the fail-safe extended spring state to hold a light workpiece in place, retracting only when air is applied to release the part.
Wire Belt Tensioner
Applies continuous spring tension on a routing belt, pulling back to slacken the line when compressed air is introduced.
Return Actuator
Resets a small probe or lever to its home position automatically, using the spring to extend the rod after the pulling task finishes.
Is the Airtac PTB Single Acting Pen-Type Cylinder PTB10X5R the Right Cylinder?
This 10 mm bore generates 23.5 N net pull at 0.5 MPa. Stepping down to a 6 mm bore yields only 7.1 N, whereas moving up to a 12 mm bore provides 33.1 N, giving you clear scaling for your fixture requirements. The internal return spring sets a 0.2 MPa minimum pressure before motion begins, and the rod safely extends if air is lost.
The short 5 mm stroke is ideal for micro-clamping. The R suffix specifies an axial inline air inlet, and the rod-end features an M8x1.0 thread. The Ø4 mm piston rod is designed strictly for coaxial thrust; if your tooling imposes side loads, add an external linear bearing guide.
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 PTB10X5R FAQ
The net pull force is 23.5 N at 0.5 MPa and 36.7 N at the 0.7 MPa maximum. A minimum of 0.2 MPa is required to overcome the return spring and retract the rod; below this, the spring holds the rod extended.
A fixed TPU bumper decelerates the rod over the last few millimeters of travel but is not adjustable; at high speeds with heavy tooling, meter-out the exhaust or add an external shock absorber. This specific model does not include a sensor magnet.
