Airtac PTB Single Acting Pen-Type Cylinder PTB16X60SCB
The AirTAC Airtac PTB Single Acting Pen-Type Cylinder PTB16X60SCB 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 PTB16X60SCB
The AirTAC PTB16X60S is a JIS pen-size single-acting pull cylinder engineered for spring-extend operation. Supplying air to the single M5x0.8 port retracts the rod, while exhaust allows the internal spring to push it back out. This provides a fail-safe extended state during air loss, delivering 65 N of net pull at 0.5 MPa and 101.2 N at the 0.7 MPa maximum. The slim SUS304 stainless body integrates a built-in magnet for position sensing and a CB double clevis for pivoting loads.
Because the powered stroke acts on the rod-side area, this pull force is lower than a matching push cylinder. The fixed TPU bumper decelerates motion over the last few millimeters of the 60 mm stroke. 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 to offset seal friction.

| 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 PTB16X60SCB Is Used
Pivoting Hold-Down Clamp
Uses the CB double clevis to swing clear of a workspace. Air pulls the 60 mm rod back to release the part, and the spring fails safe to the extended clamping position.
Tensioning Arm
Maintains constant belt or wire tension. The spring holds the material taut during exhaust, while the 65 N pull at 0.5 MPa retracts the guide to slacken or reset the line.
Retract-to-Open Gate
Controls a lightweight diverter on a packaging line. A single solenoid line pulls the gate closed, and removing air lets the spring push it back open to prevent jams.
Is the Airtac PTB Single Acting Pen-Type Cylinder PTB16X60SCB the Right Cylinder?
This 16 mm bore provides 65 N net pull at 0.5 MPa. If your pivoting application requires less force, the 12 mm bore offers 33.1 N under the same pressure. Moving up is unnecessary as this is the largest standard pen-size option, yielding the highest available pull. Keep in mind the internal spring sets a 0.2 MPa minimum pressure before motion occurs, and without live air the rod remains safely extended. The CB double clevis mount requires a matching pivoting pin, and the integrated S magnet supports reed or electronic switches.
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 PTB16X60SCB 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 opposes motion, a minimum pressure of 0.2 MPa is required before the rod retracts. Upon air loss, the spring pushes the rod back out to the extended fail-safe state.
The S suffix indicates 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 final few millimeters, so with heavy tooling mass at mid speed you should meter-out the exhaust or add an external shock absorber.
