Airtac PTB Single Acting Pen-Type Cylinder PTB10X45SCB
The AirTAC Airtac PTB Single Acting Pen-Type Cylinder PTB10X45SCB is a single acting, pull type (spring extend) pen-size mini cylinder with a Ø10mm bore and 45mm 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 PTB10X45SCB
The AirTAC PTB10X45SCB is a JIS pen-size single-acting pull cylinder where air entering the single M5x0.8 port retracts the rod, and an internal spring pushes it back out upon exhaust. This fail-safe extended state is ideal for holding or returning to a home position when air pressure drops. It yields a net pull of 23.5 N at 0.5 MPa and 36.7 N at 0.7 MPa, with the return spring force already deducted.
Built with a SUS304 stainless barrel and a slim Ø10 mm body, it saves space in tight jigs. The CB double clevis allows pivoting mount integration. Because the powered stroke acts on the smaller rod-side annular area, this pull rating is lower than a matching push cylinder. The fixed TPU bumper decelerates motion at the end of the stroke, and the -S suffix indicates a built-in piston magnet for position sensing.

| Model | Airtac PTB Single Acting Pen-Type Cylinder PTB10X45SCB |
|---|---|
| Series | PTB JIS pen-size mini cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Stroke | 45 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 PTB10X45SCB Is Used
Hold-Down Clamp
Spring pressure keeps the clamp extended safely, while a single air line pulls the rod back to release the workpiece.
Wire Tensioner
Maintains steady tension on a wire or belt in the extended state, using air to momentarily slacken the line.
Retract-to-Open Gate
Air retracts the pin to open a diverter gate on a conveyor, and the spring failsafe closes it automatically.
Is the Airtac PTB Single Acting Pen-Type Cylinder PTB10X45SCB the Right Cylinder?
This 10 mm bore generates 23.5 N net pull at 0.5 MPa. If your task needs less force, the Ø6 bore offers 7.1 N; stepping up to the Ø12 bore provides 33.1 N. Plan for a safe working load of about 14 N (roughly 60% of the 0.5 MPa rating) to account for seal friction and smooth travel. For vertical lifts, expect to hold or pull around 1.2 kg with a sane 2:1 safety margin.
The internal return spring sets a minimum operating pressure of 0.2 MPa before motion begins, with a maximum limit of 0.7 MPa. The Ø4 mm rod is designed for coaxial thrust; over this 45 mm stroke, add an external linear bearing if the load is off-axis to prevent side-loading damage. Confirm the CB double clevis fits your pivot pin before ordering.
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 PTB10X45SCB FAQ
The net pull force is 23.5 N at 0.5 MPa and 36.7 N at 0.7 MPa (maximum pressure). Because the internal spring opposes the air stroke, a minimum of 0.2 MPa is required before the rod begins to move. The spring holds the rod extended by default.
Yes, the -S suffix denotes a built-in piston magnet compatible with AirTAC reed or electronic solid-state switches. The cylinder uses a fixed TPU bumper at each end that decelerates the last few millimeters of travel; at high speeds with heavy tooling mass, meter-out the exhaust or add an external shock absorber.
