Airtac PTB Single Acting Pen-Type Cylinder PTB16X15SR
The AirTAC Airtac PTB Single Acting Pen-Type Cylinder PTB16X15SR is a single acting, pull type (spring extend) pen-size mini cylinder with a Ø16mm bore and 15mm 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 PTB16X15SR
The AirTAC PTB16X15SR 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. It provides 65 N of net pull at 0.5 MPa and 101.2 N at the 0.7 MPa maximum. The built-in magnet allows tracking with reed or electronic switches.
Because the return mechanism constantly pushes outward, losing air pressure forces the rod into a safe extended position. The slim SUS304 stainless body incorporates a fixed TPU bumper to soften end-of-stroke impacts. For smooth operation, plan for a safe working load of roughly 39 N, which accounts for seal friction and travel consistency.
Airtac PTB Single Acting Pen-Type Cylinder PTB16X15SR Technical Specifications
| Model | Airtac PTB Single Acting Pen-Type Cylinder PTB16X15SR |
|---|---|
| Series | PTB JIS pen-size mini cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Stroke | 15 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 (Ø16mm)
| Pressure | Net pull force |
|---|---|
| 0.5 MPa | 65.0 N |
| 0.7 MPa (max) | 101.2 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 PTB16X15SR Is Used
Hold-Down Clamping
Uses spring pressure to keep a part extended securely, retracting only when air is applied to release the workpiece.
Belt Tensioner
Maintains steady outward tension on a belt or wire, pulling back to slacken the line during changeovers.
Retract-to-Open Gate
Holds a diverting gate closed by default and pulls it open pneumatically to route products on a line.
Is the Airtac PTB Single Acting Pen-Type Cylinder PTB16X15SR the Right Cylinder?
This 16 mm bore generates 65 N of net pull at 0.5 MPa. Stepping down to a 12 mm bore drops the usable pull to 33.1 N, while stepping up is unavailable as 16 mm is the largest PTB option. The internal spring requires at least 0.2 MPa before motion begins, and the unit fails safe to the extended state without live air.
The R suffix specifies an axial inlet for inline plumbing, and the S suffix adds the piston magnet for position sensing. The rod end features an M10x1.0 thread. Confirm your valving only requires one solenoid line to drive the retraction stroke.
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 PTB16X15SR FAQ
It delivers 65 N of net pull at 0.5 MPa and 101.2 N at the 0.7 MPa maximum. The opposing spring requires a minimum of 0.2 MPa to overcome internal resistance before the rod retracts.
The fixed TPU bumper decelerates the rod over the last few millimeters of travel but is not adjustable; at high speeds with heavy tooling, meter-out the exhaust or add an external shock absorber. The S suffix indicates a built-in magnet compatible with reed or electronic switches.
