Airtac PTB Single Acting Pen-Type Cylinder PTB16X10CB
The AirTAC Airtac PTB Single Acting Pen-Type Cylinder PTB16X10CB is a single acting, pull type (spring extend) pen-size mini cylinder with a Ø16mm bore and 10mm 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 PTB16X10CB
The AirTAC PTB16X10CB is a JIS pen-size single-acting pull cylinder featuring a 16 mm bore and 10 mm stroke. Air entering the single M5x0.8 port retracts the Ø5 mm rod, while an internal spring pushes it back out upon exhaust release. This spring-extend design ensures the rod fails safe in the extended position during air loss, making it ideal for holding or return-to-home tasks. You get 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 slim mini body, it saves space in tight jigs and light end-of-arm tooling. The CB double clevis back cover accommodates pivoting loads. A fixed TPU bumper decelerates the stroke at both ends. Because the return spring counteracts the air stroke, a minimum pressure of 0.2 MPa is required before motion begins.
Airtac PTB Single Acting Pen-Type Cylinder PTB16X10CB Technical Specifications
| Model | Airtac PTB Single Acting Pen-Type Cylinder PTB16X10CB |
|---|---|
| Series | PTB JIS pen-size mini cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Stroke | 10 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 PTB16X10CB Is Used
Pivoting Hold-Down Clamp
Uses the CB double clevis to swing into position, applying 65 N of net pull at 0.5 MPa to secure parts during machining.
Wire Belt Tensioner
Maintains steady tension on belts or cables, with the internal spring automatically extending the rod to compensate for slack.
Retract-to-Open Gate
Pulls a lightweight diverter gate out of the product flow path on command, letting the spring safely push it closed if air fails.
Is the Airtac PTB Single Acting Pen-Type Cylinder PTB16X10CB the Right Cylinder?
This 16 mm bore provides 65 N net pull at 0.5 MPa. If your task needs less force, the 12 mm bore yields 33.1 N at the same pressure; stepping up is impossible as 16 mm is the largest PTB option. Plan for a safe working load of about 39 N, which assumes 60 percent of the rated 0.5 MPa force to account for seal friction and smooth travel.
Remember the spring sets a minimum 0.2 MPa operating pressure before the rod retracts. The thin Ø5 mm rod handles coaxial thrust well, but over long strokes or off-axis loads you should add an external guide or linear bearing to prevent side-load damage. Confirm the CB double clevis and M10x1.0 rod-end thread match your mounting geometry.
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 PTB16X10CB FAQ
The net pull force is 65 N at 0.5 MPa and 101.2 N at the 0.7 MPa maximum. Because an internal spring holds the rod extended, a minimum pressure of 0.2 MPa is required before air can retract the piston.
It uses a fixed TPU bumper at each end to decelerate the last few millimeters of travel. The bumper is not adjustable or a locking brake, so at higher speeds with real tooling mass you should meter-out the exhaust or add an external shock absorber.
