Airtac PTB Single Acting Pen-Type Cylinder PTB16X10R
The AirTAC Airtac PTB Single Acting Pen-Type Cylinder PTB16X10R is a single acting, pull type (spring extend) pen-size mini cylinder with a Ø16mm 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 PTB16X10R
The AirTAC PTB16X10R 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 65 N of net pull at 0.5 MPa, reaching 101.2 N at the 0.7 MPa maximum. Because the return spring constantly opposes the air stroke, the rod stays safely extended on air loss.
This variant features an R axial inlet for in-line plumbing and a fixed TPU bumper at each end to soften end-of-stroke impacts. The slim SUS304 stainless body saves space in tight jigs. Plan for a safe working load of about 39 N, which is roughly 60 percent of the rated figure, to account for seal friction and smooth travel.
Airtac PTB Single Acting Pen-Type Cylinder PTB16X10R Technical Specifications
| Model | Airtac PTB Single Acting Pen-Type Cylinder PTB16X10R |
|---|---|
| Series | PTB JIS pen-size mini cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 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 (Ø16mm)
| Pressure | Net pull force |
|---|---|
| 0.5 MPa | 65.0 N |
| 0.7 MPa (max) | 101.2 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 PTB16X10R Is Used
Hold-Down Clamp
Keeps a workpiece clamped under spring pressure, retracting only when air is applied to release the part.
Wire Tensioner
Maintains steady pulling tension on a wire or belt, yielding back automatically when air pressure cycles.
Retract-to-Open Gate
Holds a diverter gate open by default and pulls it closed momentarily to sort items on a line.
Is the Airtac PTB Single Acting Pen-Type Cylinder PTB16X10R the Right Cylinder?
This 16 mm bore generates 65 N net pull at 0.5 MPa. If your task needs less force, the 12 mm bore offers 33.1 N at the same pressure. Since 16 mm is the largest PTB option, moving higher requires switching to a double-acting PB body. The internal spring sets a 0.2 MPa minimum pressure before motion begins, and the rod fail-safe extends when exhaust vents.
Confirm the 10 mm stroke fits your cycle. The thin Ø5 mm rod handles coaxial thrust well, but over this short stroke you should still avoid side loads by adding an external guide if tooling mass is high. The R back cover provides direct axial mounting for compact manifolds.
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 PTB16X10R FAQ
The net pull force is 65 N at 0.5 MPa and 101.2 N at the 0.7 MPa maximum. A minimum pressure of 0.2 MPa is required to overcome the return spring and move the rod. Releasing air lets the spring fail-safe extend the rod back out.
A fixed TPU bumper decelerates the rod over the last few millimeters of travel but is not adjustable. At higher speeds with real tooling mass, meter-out the exhaust or add an external shock absorber. This model does not include a sensor magnet.
