Airtac PTB Single Acting Pen-Type Cylinder PTB16X15R
The AirTAC Airtac PTB Single Acting Pen-Type Cylinder PTB16X15R is a single acting, pull type (spring extend) pen-size mini cylinder with a Ø16mm bore and 15mm 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 PTB16X15R
The AirTAC PTB16X15R is a JIS pen-size single-acting pull cylinder where air entering one M5x0.8 port retracts the rod, while an internal spring pushes it back out. It provides 65 N of net pull at 0.5 MPa and 101.2 N at the 0.7 MPa maximum. Because the return spring constantly opposes the air stroke, these figures already reflect the usable force after spring deduction.
This configuration uses an axial R back cover for inline plumbing, keeping the slim SUS304 stainless body compact for tight jigs. A fixed TPU bumper cushions the stroke ends. If pneumatic pressure drops, the spring forces the rod to its extended state, creating a fail-safe out condition for hold-down or return-to-home mechanisms.
Airtac PTB Single Acting Pen-Type Cylinder PTB16X15R Technical Specifications
| Model | Airtac PTB Single Acting Pen-Type Cylinder PTB16X15R |
|---|---|
| Series | PTB JIS pen-size mini cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Stroke | 15 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 PTB16X15R Is Used
Hold-Down Clamping
Uses the spring-extended rod to hold parts securely by default, retracting only when air is applied to release the workpiece.
Wire Tensioning
Maintains constant outward tension on filaments or belts, pulling back to relieve tension during automated threading cycles.
Retract-To-Open Gate
Keeps a routing gate closed via spring force on air loss, opening the lane safely only when pressurized to retract the rod.
Is the Airtac PTB Single Acting Pen-Type Cylinder PTB16X15R the Right Cylinder?
This 16 mm bore yields 65 N net pull at 0.5 MPa. Stepping down to a 12 mm bore drops the usable pull to 33.1 N, while no larger single-acting option exists in this pen series, making the 16 mm the top choice for maximum pull force. Plan for a safe working load of about 39 N, which assumes roughly 60 percent of the rated figure to account for seal friction.
The internal spring establishes a 0.2 MPa minimum pressure before motion begins. With a 15 mm stroke, the slender Ø5 mm rod handles coaxial thrust well, but avoid side loads. Confirm your build requires the R axial inlet and no magnetic sensor switch.
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 PTB16X15R FAQ
It delivers 65 N net pull at 0.5 MPa and 101.2 N at the 0.7 MPa maximum. The internal spring requires at least 0.2 MPa before the rod moves, and the rod fails safe to the extended position on air loss.
It uses a fixed TPU bumper at each end to decelerate the last few millimeters of travel. Because it is not adjustable, metering out the exhaust or adding an external shock absorber is recommended when cycling real tooling mass at higher speeds.
