Airtac PTB Single Acting Pen-Type Cylinder PTB10X40R
The AirTAC Airtac PTB Single Acting Pen-Type Cylinder PTB10X40R is a single acting, pull type (spring extend) pen-size mini cylinder with a Ø10mm bore and 40mm 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 PTB10X40R
The AirTAC PTB10X40R is a JIS pen-size single-acting pull cylinder with a 10 mm bore and 40 mm stroke. Air entering the M5x0.8 port retracts the Ø4 mm rod, while an internal spring pushes it back out upon exhaust release. This fail-safe extended state is ideal for holding or returning tools when air pressure drops. It supplies about 23.5 N of net pull at 0.5 MPa.
Built with a SUS304 stainless barrel and slim mini body, it saves space in tight jigs. The fixed TPU bumper decelerates motion at stroke ends. Because pulling acts on the smaller rod-side area, this net force is lower than a matching push-type unit. Plan for a safe working load of roughly 14 N, which accounts for seal friction and smooth travel.
Airtac PTB Single Acting Pen-Type Cylinder PTB10X40R Technical Specifications
| Model | Airtac PTB Single Acting Pen-Type Cylinder PTB10X40R |
|---|---|
| Series | PTB JIS pen-size mini cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Stroke | 40 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 PTB10X40R Is Used
Hold-Down Clamp
Uses spring pressure to keep a workpiece extended safely, then retracts the rod via air to release the part for machining.
Belt Tensioner
Applies steady pulling force on a belt or wire, with the 40 mm stroke absorbing slack during automated cycling.
Retract-to-Open Gate
Pulls a lightweight diverter gate closed on actuation, relying on the spring to open it automatically on air loss.
Is the Airtac PTB Single Acting Pen-Type Cylinder PTB10X40R the Right Cylinder?
Select this 10 mm bore actuator when you need 23.5 N of net pull at 0.5 MPa (36.7 N at the 0.7 MPa maximum). If your task requires less force, the Ø6 bore offers 7.1 N at 0.5 MPa. For heavier tensioning, stepping up to the Ø12 bore provides 33.1 N. Remember the internal spring sets a 0.2 MPa minimum pressure before motion begins. This PTB10X40R configuration features an R axial inlet and lacks a sensor magnet.
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 PTB10X40R FAQ
It provides a net pull of 23.5 N at 0.5 MPa and 36.7 N at the 0.7 MPa maximum. The return spring requires a 0.2 MPa minimum pressure before the rod moves. Without live air, the spring holds the rod fail-safe extended.
The Ø4 mm rod is designed for coaxial thrust only; over the 40 mm stroke, add an external guide to prevent bending. The fixed TPU bumper only decelerates the last few mm, so meter-out the exhaust or add a shock absorber when moving real tooling mass at mid to high speeds.
