Airtac PTB Single Acting Pen-Type Cylinder PTB16X30SR
The AirTAC Airtac PTB Single Acting Pen-Type Cylinder PTB16X30SR is a single acting, pull type (spring extend) pen-size mini cylinder with a Ø16mm bore and 30mm 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 PTB16X30SR
The AirTAC PTB16X30SR is a JIS pen-size single-acting pull cylinder. Air entering the single M5x0.8 port retracts the Ø5 mm rod, while an internal spring pushes it back out upon exhaust release. This provides 65 N of net pull at 0.5 MPa. Because the return spring constantly opposes the air stroke, the rod fails safe in the extended position if air pressure drops.
A built-in magnet allows position sensing with reed or electronic switches. The slim SUS304 stainless body saves space in tight jigs, and a fixed TPU bumper cushions the stroke ends. For smooth operation, plan for a safe working load of about 39 N, which accounts for roughly sixty percent of the rated force to overcome seal friction.
Airtac PTB Single Acting Pen-Type Cylinder PTB16X30SR Technical Specifications
| Model | Airtac PTB Single Acting Pen-Type Cylinder PTB16X30SR |
|---|---|
| Series | PTB JIS pen-size mini cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Stroke | 30 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 PTB16X30SR Is Used
Hold-Down Clamping
Keeps a workpiece secured by pulling a clamp pin, with the spring automatically extending the rod to release the part safely upon air loss.
Belt Tensioner
Maintains steady tension on a conveyor belt by retracting against the spring force, providing a consistent pull of about 3.3 kg with a two-to-one safety margin.
Retract-To-Open Gate
Pulls a lightweight diverter gate closed during processing and springs it open to a safe home position when the pneumatic signal stops.
Is the Airtac PTB Single Acting Pen-Type Cylinder PTB16X30SR the Right Cylinder?
This 16 mm bore generates 65 N net pull at 0.5 MPa and 101.2 N at the 0.7 MPa maximum. If your task needs less force, the 12 mm bore yields 33.1 N at 0.5 MPa. For heavier demands, stepping up requires a double-acting PB cylinder, as 16 mm is the largest pen-size option. The internal spring sets a 0.2 MPa minimum pressure before motion begins.
The thin Ø5 mm rod handles coaxial thrust well, but over this 30 mm stroke you should add an external linear bearing if any off-axis load exists. This configuration includes the S magnet for sensing and the R axial back cover for inline plumbing. Rod-end threading is M10x1.0.
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 PTB16X30SR FAQ
The net pull force is 65 N at 0.5 MPa and 101.2 N at the 0.7 MPa maximum. Because the internal spring constantly opposes air input, a minimum pressure of 0.2 MPa is required before the rod begins to retract. Without air, the spring holds the rod extended.
The S suffix denotes a built-in piston magnet compatible with reed or electronic switches. Cushioning relies on a fixed TPU bumper at each end. It only decelerates the last few millimeters of travel, so at higher speeds with real tooling mass you should meter-out the exhaust or add an external shock absorber.
