Airtac PTB Single Acting Pen-Type Cylinder PTB10X30SCB
The AirTAC Airtac PTB Single Acting Pen-Type Cylinder PTB10X30SCB is a single acting, pull type (spring extend) pen-size mini cylinder with a Ø10mm bore and 30mm 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 PTB10X30SCB
The AirTAC PTB10X30SCB is a JIS pen-size single-acting pull cylinder where air entering one M5x0.8 port retracts the rod, and exhausting that air lets an internal spring push it back out. Because the return spring constantly fights the air stroke, this 10mm bore model provides a net usable pull of 23.5N at 0.5MPa and 36.7N at the 0.7MPa maximum. The slim SUS304 stainless body and Ø4mm rod keep weight low for tight jigs and end-of-arm tooling.
Losing air pressure forces the rod to its extended state, offering a fail-safe out position for hold-down or return-to-home tasks. The CB double clevis back cover accommodates pivoting loads, while the built-in magnet (-S) supports reed or electronic switches. A fixed TPU bumper cushions the stroke ends, and the single air line simplifies valving compared to double-acting units.

| Model | Airtac PTB Single Acting Pen-Type Cylinder PTB10X30SCB |
|---|---|
| Series | PTB JIS pen-size mini cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Stroke | 30 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 (Ø10mm)
| Pressure | Net pull force |
|---|---|
| 0.5 MPa | 23.5 N |
| 0.7 MPa (max) | 36.7 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 PTB10X30SCB Is Used
Pivoting Hold-Down Clamp
Uses the CB double clevis to swing into place; air retracts the rod to grip parts, and the spring fails safe to release if air drops.
Wire Belt Tensioner
Pulls back to maintain precise tension on a routing belt; the single air line keeps control panels simple while the spring holds baseline tension.
Retract-to-Open Gate
Air pulls the 30mm stroke back to open a small diverter gate on a conveyor, and the spring automatically closes it during an air loss event.
Is the Airtac PTB Single Acting Pen-Type Cylinder PTB10X30SCB the Right Cylinder?
When sizing this 10mm bore, consider its 23.5N net pull at 0.5MPa. Dropping to the Ø6 bore yields only 7.1N, which is likely too weak for a pivoting clevis setup, whereas stepping up to the Ø12 bore provides 33.1N of retraction force. Plan for a safe working load of roughly 14N, which accounts for seal friction at 60% of the 0.5MPa rating. For vertical movements, expect to hold or pull about 1.2kg with a sane 2:1 safety margin.
The internal spring mandates a 0.2MPa minimum pressure before motion begins, and the unit fails safe to the extended position on air loss. The thin Ø4mm rod handles coaxial thrust well but requires an external guide if subjected to off-axis loads. Confirm your pivot pin matches the CB clevis and that your stroke does not exceed the 60mm single-acting limit.
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 PTB10X30SCB FAQ
This 10mm bore cylinder provides a net pull of 23.5N at 0.5MPa and 36.7N at the 0.7MPa maximum. The internal spring requires at least 0.2MPa to overcome its resistance and initiate the retract stroke. On air loss, the spring forces the rod to the extended fail-safe position.
It uses a fixed TPU bumper at each end to decelerate the last few millimeters of travel; because it is not adjustable, metering out the exhaust or adding an external shock absorber is recommended for high-speed tooling. The built-in magnet works with AirTAC reed or electronic switches for position sensing.
