Airtac PTB Single Acting Pen-Type Cylinder PTB10X45SR
The AirTAC Airtac PTB Single Acting Pen-Type Cylinder PTB10X45SR 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 PTB10X45SR
The AirTAC PTB10X45SR 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 return spring constantly opposes the air stroke, these figures already reflect the usable force after spring deduction.
This configuration includes an axial R back cover for inline plumbing and a built-in S magnet for position sensing. The SUS304 stainless build and fixed TPU bumper ensure durability in tight spaces. Plan for a safe working load of about 14 N, which accounts for seal friction and smooth travel. The slim Ø4 mm rod is designed strictly for coaxial thrust, so over this 45 mm stroke you should add an external linear bearing if any off-axis load is present.
Airtac PTB Single Acting Pen-Type Cylinder PTB10X45SR Technical Specifications
| Model | Airtac PTB Single Acting Pen-Type Cylinder PTB10X45SR |
|---|---|
| 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 PTB10X45SR Is Used
Hold-Down Clamping
Uses spring pressure to keep a workpiece extended safely, applying 23.5 N net pull at 0.5 MPa to retract and release the part when air is applied.
Wire Belt Tensioner
Maintains steady tension on belts or wires by default, using the single air line to pull back and slacken the material during changeovers.
Retract-To-Open Gate
Holds a lightweight diverter gate closed via spring force, opening the path only when the solenoid energizes the M5x0.8 port to pull the rod.
Is the Airtac PTB Single Acting Pen-Type Cylinder PTB10X45SR the Right Cylinder?
This 10 mm bore generates 23.5 N net pull at 0.5 MPa. If your application requires less force, the Ø6 bore offers 7.1 N at the same pressure. If you need more power, stepping up to the Ø12 bore yields 33.1 N. The internal spring sets a 0.2 MPa minimum pressure before motion begins, and without live air the rod stays safely extended.
Confirm your ordering essentials: this PTB10X45SR features a 45 mm stroke, an M8x1.0 rod-end thread, and the S magnet compatible with reed or electronic switches. The fixed TPU bumper only decelerates the last few millimeters of travel, so at mid-to-high speeds with real tooling mass you should meter-out the exhaust or add an external shock absorber.
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 PTB10X45SR FAQ
It delivers 23.5 N net pull at 0.5 MPa and 36.7 N at 0.7 MPa. The internal spring requires a minimum of 0.2 MPa before the rod moves. Upon air loss, the spring fails safe by pushing the rod to the extended position.
The built-in S magnet works with both reed and electronic AirTAC switches. The fixed TPU bumper at each end decelerates the last few millimeters of travel but is not adjustable; for high tooling mass, add external shock absorption.
