Airtac PTB Single Acting Pen-Type Cylinder PTB16X60R
The AirTAC Airtac PTB Single Acting Pen-Type Cylinder PTB16X60R is a single acting, pull type (spring extend) pen-size mini cylinder with a Ø16mm bore and 60mm 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 PTB16X60R
The AirTAC PTB16X60R is a JIS pen-size single-acting pull cylinder with a 16 mm bore and 60 mm stroke. Air entering the M5x0.8 port retracts the rod, while an internal spring pushes it back out. Because the return spring constantly opposes the air stroke, this model yields a usable 65 N net pull at 0.5 MPa (101.2 N at the 0.7 MPa maximum). The R suffix designates an axial inlet for inline plumbing.
Without live air, the spring reliably holds the rod extended, making it fail-safe for tasks where the outward position is the secure state. The slim SUS304 stainless body incorporates a fixed TPU bumper at each end to soften end-of-stroke impacts. For smooth operation, plan for a safe working load of about 39 N, which accounts for roughly 60 percent of the rated 0.5 MPa force.

| Rod diameter | Ø5 mm |
| Stroke | 60 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 PTB16X60R Is Used
Tension Hold-Down
Pulls clamps tight against a part with 65 N force, releasing tension instantly when air is removed.
Retract-To-Open Gate
Uses the single air line to pull a diverter gate open, letting the spring push it closed as a fail-safe.
Wire Belt Tensioner
Maintains steady pulling tension on a belt or wire, automatically extending outward if air pressure drops.
Is the Airtac PTB Single Acting Pen-Type Cylinder PTB16X60R the Right Cylinder?
Selecting this 16 mm bore provides the highest net pull in the PTB family, stepping up from the 33.1 N available at 0.5 MPa from a 12 mm bore. Since 16 mm is the largest option, there is no larger bore to size up to; if 65 N is insufficient, a double-acting PB cylinder may be required. The internal spring sets a minimum 0.2 MPa pressure before motion begins. Confirm your ordering essentials: this configuration includes a 60 mm stroke, no sensor magnet, and an R axial back cover.
Because this unit features the maximum 60 mm single-acting stroke, the slender Ø5 mm rod is prone to bending under off-axis loads. Add an external linear bearing or guide for any tooling that cannot maintain perfectly coaxial thrust. Furthermore, the fixed TPU bumper only decelerates the last few millimeters of travel; at high cycling speeds with heavy end-of-arm tooling, meter-out the exhaust or install an external shock absorber to prevent bottoming out.
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 PTB16X60R FAQ
The net pull force is 65 N at 0.5 MPa and 101.2 N at the 0.7 MPa maximum. A minimum of 0.2 MPa is required to overcome the return spring and retract the rod. If air loss occurs, the spring forces the rod back out to the extended position.
Air drives the rod inward on the retract stroke, and the spring pushes it outward. A fixed TPU bumper at each end absorbs the final few millimeters of impact. Because the bumper is non-adjustable, high speeds with heavy masses require metering the exhaust or adding an external shock absorber.
