Airtac PTB Single Acting Pen-Type Cylinder PTB16X10SR
The AirTAC Airtac PTB Single Acting Pen-Type Cylinder PTB16X10SR 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 PTB16X10SR
The AirTAC PTB16X10SR is a JIS pen-size single-acting pull cylinder where air retracts the rod and an internal spring pushes it back out. If air pressure drops, the spring ensures the rod fails safe in the extended position. It yields 65 N of net pull at 0.5 MPa, reaching 101.2 N at the 0.7 MPa maximum. Because the powered stroke acts on the smaller rod-side area, this pull figure is naturally lower than the equivalent push force of a matching bore.
This variant includes a built-in piston magnet for position sensing with reed or electronic switches, and an R axial inlet for inline plumbing. The slim SUS304 stainless body saves space on tight jigs. A fixed TPU bumper cushions the stroke ends. For smooth travel, plan for a safe working load of roughly 39 N, which accounts for seal friction at about sixty percent of the rated force.
Airtac PTB Single Acting Pen-Type Cylinder PTB16X10SR Technical Specifications
| Model | Airtac PTB Single Acting Pen-Type Cylinder PTB16X10SR |
|---|---|
| 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 PTB16X10SR Is Used
Hold-Down Clamp
Uses spring pressure to keep a workpiece held out safely, applying 65 N of net pull at 0.5 MPa to retract the clamp when air is applied.
Wire Tensioner
Maintains constant outward tension on a belt or wire, pulling back to release the line using a single solenoid air line for simpler valving.
Retract-to-Open Gate
Blocks a conveyor lane by default with the rod extended, then retracts the 10 mm stroke to open the gate only when pneumatic pressure is applied.
Is the Airtac PTB Single Acting Pen-Type Cylinder PTB16X10SR the Right Cylinder?
Select this 16 mm bore, 10 mm stroke model when you need short retraction with a fail-safe extend state. If your task requires less force, stepping down to the 12 mm bore gives 33.1 N of net pull at 0.5 MPa. Moving up is not possible within this pen-size series as 16 mm is the largest option. The internal return spring sets a minimum 0.2 MPa operating pressure before the rod will move. Confirm your valving needs only one M5x0.8 port and an M10x1.0 rod-end thread for tooling attachment.
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 PTB16X10SR FAQ
The PTB16X10SR provides 65 N of net pull at 0.5 MPa and 101.2 N at the 0.7 MPa maximum. The internal spring requires a minimum 0.2 MPa of air pressure before the rod begins to retract, and the rod fails safe in the extended position on air loss.
A fixed TPU bumper decelerates the rod at the stroke ends, but at higher speeds with real tooling mass you should meter-out the exhaust or add an external shock absorber. The built-in magnet works with reed or electronic switches for precise position sensing.
