Airtac PTB Single Acting Pen-Type Cylinder PTB16X40SCB
The AirTAC Airtac PTB Single Acting Pen-Type Cylinder PTB16X40SCB is a single acting, pull type (spring extend) pen-size mini cylinder with a Ø16mm bore and 40mm 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 PTB16X40SCB
The AirTAC PTB16X40SCB is a JIS pen-size single-acting pull cylinder where air entering the M5x0.8 port retracts the rod, and an internal spring pushes it back out. This fail-safe extended state is ideal for holding parts when air pressure drops. It yields 65 N of net pull at 0.5 MPa and 101.2 N at the 0.7 MPa maximum.
Built with a SUS304 stainless barrel and a slim 16 mm body, it saves space on light end-of-arm tooling. The CB double clevis allows pivoting loads, and the built-in magnet supports reed or electronic switches. A fixed TPU bumper cushions the stroke ends.
Airtac PTB Single Acting Pen-Type Cylinder PTB16X40SCB Technical Specifications
| Model | Airtac PTB Single Acting Pen-Type Cylinder PTB16X40SCB |
|---|---|
| Series | PTB JIS pen-size mini cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Stroke | 40 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 PTB16X40SCB Is Used
Pivoting Hold-Down Clamp
Uses the CB clevis to swing onto a workpiece, applying 65 N of pull to secure it during machining.
Wire Belt Tensioner
Maintains steady tension on a routing belt, with the spring automatically extending the rod to take up slack on air loss.
Retract-to-Open Gate
Pulls a diverter gate closed during operation and safely springs it open to clear the conveyor path when air is removed.
Is the Airtac PTB Single Acting Pen-Type Cylinder PTB16X40SCB the Right Cylinder?
This 16 mm bore gives 65 N net pull at 0.5 MPa. Stepping down, the 12 mm bore yields 33.1 N, which is often too weak for heavier clamping. Moving up is not possible as this is the largest PTB option. Plan for a safe working load of roughly 39 N, which is about 60 percent of the rated figure, to account for seal friction.
The internal spring sets a 0.2 MPa minimum pressure before motion begins. Because the rod is only Ø5 mm, use an external linear bearing for the 40 mm stroke to prevent side-load damage. Confirm your ordering needs: the S suffix adds the magnet, and CB specifies the double clevis pivot mount.
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 PTB16X40SCB FAQ
It provides 65 N of net pull at 0.5 MPa and 101.2 N at the 0.7 MPa maximum. The return spring requires a minimum of 0.2 MPa to overcome its force and move the rod.
The fixed TPU bumper decelerates the rod only for the last few millimeters of travel. For higher speeds with real tooling mass, add an external shock absorber. The S suffix denotes a built-in magnet compatible with reed or electronic switches.
