Airtac PTB Single Acting Pen-Type Cylinder PTB10X30R
The AirTAC Airtac PTB Single Acting Pen-Type Cylinder PTB10X30R 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 PTB10X30R
The AirTAC PTB10X30R is a JIS pen-size single-acting pull cylinder where air entering one M5x0.8 port retracts the rod, while an internal spring pushes it back out. It provides 23.5 N of net pull at 0.5 MPa and 36.7 N at 0.7 MPa. Because the spring constantly holds the rod extended, losing air pressure automatically drives the tool to a safe outward state.
This slim SUS304 stainless body features an axial R inlet for inline plumbing and a fixed TPU bumper at each end. For smooth operation, plan for a safe working load of about 14 N, which accounts for seal friction. The Ø4 mm rod handles coaxial thrust well, but over this 30 mm stroke you should add an external guide if any off-axis load is present.

|---|---|
| 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 PTB10X30R Is Used
Hold-Down Clamp
Pulls a lightweight latch down during processing and releases to let the spring push the jaw open when air stops.
Belt Tensioner
Maintains steady outward tension on a timing belt and retracts to slacken the line for maintenance changes.
Retract-to-Open Gate
Draws a diverter gate back to redirect small parts, relying on the spring to push the guide safely home on exhaust.
Is the Airtac PTB Single Acting Pen-Type Cylinder PTB10X30R the Right Cylinder?
Sizing this actuator requires comparing its 23.5 N net pull at 0.5 MPa against neighboring bores. Stepping down to Ø6 yields only 7.1 N, whereas stepping up to Ø12 provides 33.1 N. Choose the Ø10 if 23.5 N is sufficient, keeping in mind the return spring sets a 0.2 MPa minimum pressure before motion begins.
Confirm your plumbing uses the axial R back cover and M5x0.8 port. Since the powered stroke pulls inward and the spring fails safe extended, verify your fixture expects a retracted actuation and an extended rest position.
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 PTB10X30R FAQ
It generates 23.5 N of net pull at 0.5 MPa and 36.7 N at 0.7 MPa. The internal return spring requires a minimum of 0.2 MPa to overcome spring tension and move the rod. Without air, the spring holds the rod fully extended.
It uses a fixed TPU bumper at each end to decelerate the last few millimeters of travel. Because it is not adjustable, running at high speeds with heavy tooling mass can bottom out the bumper. In those cases, meter-out the exhaust or add an external shock absorber.
