Airtac PTB Single Acting Pen-Type Cylinder PTB12X60SCB
The AirTAC Airtac PTB Single Acting Pen-Type Cylinder PTB12X60SCB is a single acting, pull type (spring extend) pen-size mini cylinder with a Ø12mm 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 PTB12X60SCB
The AirTAC PTB12X60SCB is a JIS pen-size single-acting pull cylinder, meaning air entering the M5x0.8 port retracts the rod while an internal spring pushes it back out. It provides 33.1 N of net pull at 0.5 MPa and 51.8 N at 0.7 MPa. Because the spring constantly holds the rod extended, the cylinder fails safe in the out position if air pressure drops.
This 60 mm stroke unit features a built-in piston magnet for position sensing and a CB double clevis back cover for pivoting loads. The slim SUS304 stainless body includes a fixed TPU bumper at each end. For smooth operation, plan for a safe working load of about 20 N, which accounts for seal friction at typical pressures.

|---|---|
| Series | PTB JIS pen-size mini cylinder |
| Bore size | Ø12 mm |
| 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 |

| 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 (Ø12mm)
| Pressure | Net pull force |
|---|---|
| 0.5 MPa | 33.1 N |
| 0.7 MPa (max) | 51.8 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 PTB12X60SCB Is Used
Pivoting Hold-Down Clamp
Uses the CB double clevis to swing into position, applying 33.1 N net pull to secure light panels while the spring safely holds the clamp open.
Wire Belt Tensioner
Maintains steady tension on packaging belts, relying on the spring-extend design to automatically take up slack during operation.
Retract-to-Open Gate
Powers a small diverter gate closed via air pressure, then springs back to the open position to clear the conveyor lane when exhaust is released.
Is the Airtac PTB Single Acting Pen-Type Cylinder PTB12X60SCB the Right Cylinder?
This 12 mm bore provides 33.1 N net pull at 0.5 MPa. If your jig needs less force, the 10 mm bore yields 23.5 N; stepping up to the 16 mm bore offers 65.0 N. Remember the internal spring requires a minimum 0.2 MPa pressure to overcome before retraction begins, and the rod safely stays extended without live air.
At the maximum 60 mm stroke, the slender Ø5 mm rod needs an external guide or linear bearing to prevent side-loading damage. The CB double clevis allows pivoting, and the M10x1.0 rod-end thread secures your tooling. Confirm your solenoid matches the single air line requirement.
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 PTB12X60SCB FAQ
It delivers 33.1 N net pull at 0.5 MPa and 51.8 N at 0.7 MPa. Because an internal spring constantly pushes the rod out, a minimum of 0.2 MPa air pressure is required before the rod can retract.
The built-in magnet works with AirTAC reed or electronic switches for end-of-stroke detection. A fixed TPU bumper decelerates the piston in the final few millimeters, but at high speeds with heavy tooling you should meter-out the exhaust or add an external shock absorber.
