Airtac PTB Single Acting Pen-Type Cylinder PTB10X5CB
The AirTAC Airtac PTB Single Acting Pen-Type Cylinder PTB10X5CB is a single acting, pull type (spring extend) pen-size mini cylinder with a Ø10mm bore and 5mm 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 PTB10X5CB
The AirTAC PTB10X5CB is a JIS pen-size single-acting pull cylinder where air entering one M5x0.8 port retracts the rod, and an internal spring pushes it back out. It delivers 23.5 N of net pull at 0.5 MPa (36.7 N at the 0.7 MPa maximum). Because the return spring constantly pushes outward, the rod automatically extends to a safe state if air pressure drops.
This variant uses a CB double clevis back cover for pivoting mountings and carries no sensor magnet. The slim SUS304 stainless body saves space on light end-of-arm tooling. A fixed TPU bumper cushions the stroke ends, and the M8x1.0 rod-end thread handles your tooling attachment.
Airtac PTB Single Acting Pen-Type Cylinder PTB10X5CB Technical Specifications
| Model | Airtac PTB Single Acting Pen-Type Cylinder PTB10X5CB |
|---|---|
| Series | PTB JIS pen-size mini cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Stroke | 5 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 PTB10X5CB Is Used
Pivoting Hold-Down Clamp
Uses the CB double clevis to swing a small latch, pulling the rod back to unclamp a delicate part before the spring safely extends it.
Wire Belt Tensioner
Applies steady retraction to maintain tension on a light packaging belt, relying on the spring to slacken the line on air loss.
Retract-to-Open Gate
Pulls a miniature diverter gate out of the product stream upon actuation, letting the internal spring push the gate closed as a default.
Is the Airtac PTB Single Acting Pen-Type Cylinder PTB10X5CB the Right Cylinder?
When sizing this bore, note the 23.5 N net pull at 0.5 MPa is lower than the matching push cylinder because pull acts on the smaller rod-side area. If your pivoting clamp needs less force, stepping down to the Ø6 bore gives 7.1 N; if you need more retraction muscle, the Ø12 bore provides 33.1 N. The internal spring sets a 0.2 MPa minimum pressure before the rod moves, and the CB clevis requires a matching pin.
For real-world planning, target a safe working load of about 14 N (roughly 60 percent of the 0.5 MPa figure) to account for seal friction. Vertically, this translates to holding or pulling about 1.2 kg with a sane 2:1 margin. The Ø4 mm rod is built for coaxial thrust, so avoid side loads.
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 PTB10X5CB FAQ
It provides 23.5 N of net pull at 0.5 MPa and 36.7 N at the 0.7 MPa maximum. The internal spring requires a minimum of 0.2 MPa before the rod moves, and the rod fails safe in the extended position without air.
It uses a fixed TPU bumper at each end to decelerate the last few millimeters of travel. Because it is not adjustable, you should meter-out the exhaust or add an external shock absorber when cycling real tooling mass at higher speeds.
