Airtac PSB Single Acting Compact Cylinder PSB16X15SR
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB16X15SR is a single acting, push type (spring return) pen-size mini cylinder with a Ø16mm bore and 15mm stroke. A single air port drives the push stroke; the built-in return spring resets the rod when air is released, so only one solenoid line is needed.

About the Airtac PSB Single Acting Compact Cylinder PSB16X15SR
The AirTAC PSB16X15SR is a JIS pen-size single-acting push cylinder that extends via one M5x0.8 air port and relies on an internal spring to retract. It yields 74.8 N of net push at 0.5 MPa, with the return spring force already subtracted. This fail-safe design ensures the rod pulls back home automatically upon air loss.
The slim SUS304 stainless body integrates an R axial inlet, a fixed TPU bumper, and a built-in magnet for position sensing. Because the internal return spring opposes motion, a minimum 0.2 MPa is required before the rod extends. Plan for a safe working load of roughly 45 N, which is about 60 percent of the 0.5 MPa rating.
Airtac PSB Single Acting Compact Cylinder PSB16X15SR Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB16X15SR |
|---|---|
| Series | PSB JIS pen-size mini cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Stroke | 15 mm |
| Acting type | Single acting, push type (spring return) |
| 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 (push by air) |
| Max standard stroke | Up to 60 mm |
The spring holds the rod retracted; applying air pushes the rod out, and removing air lets the spring return it. Forces below are the NET spring-deducted values from the AirTAC thrust table. Confirm against the product label before installation.
Net Push Force (Ø16mm)
| Pressure | Net push force |
|---|---|
| 0.5 MPa | 74.8 N |
| 0.7 MPa (max) | 115.0 N |
These are the usable push 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 PSB Single Acting Compact Cylinder PSB16X15SR Is Used
Stamping Ejector
Pushes formed metal blanks out of a die on a press line, with the spring ensuring the pin retracts clear before the next cycle.
Package Diverter
Extends a lightweight gate arm to route cardboard cartons down a sorting lane, safely defaulting to the closed position on air loss.
Clamp Release
Applies 45 N of holding force to secure a film roll during sealing, then vents to let the spring pull back and release the web.
Is the Airtac PSB Single Acting Compact Cylinder PSB16X15SR the Right Cylinder?
This 16 mm bore generates 74.8 N net push at 0.5 MPa, sitting below the next size up and well above the 42.9 N offered by a 12 mm bore. The internal spring dictates a 0.2 to 0.7 MPa operating range, guaranteeing a fail-safe retracted state during pressure drops. Confirm your ordering essentials: 16 mm bore, 15 mm stroke, S magnet, R axial inlet, and your preferred mounting bracket.
The Ø5 mm rod handles coaxial thrust, but over long strokes or off-axis loads you should add an external linear bearing. The fixed TPU bumper decelerates the final few millimeters; at high speeds with heavy tooling, meter-out the exhaust or install an external shock absorber.
Quick checklist
- ✓ Net push force at your working pressure
- ✓ Only one air line / solenoid needed
- ✓ Fail-safe retract 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 PSB Single Acting Compact Cylinder PSB16X15SR FAQ
It provides 74.8 N of net push at 0.5 MPa and 115 N at 0.7 MPa. Because an internal spring returns the rod, a minimum of 0.2 MPa is required to overcome the spring before extension begins. The rod stays fail-safe retracted whenever air pressure is removed.
Yes, the built-in S magnet works with both reed and electronic AirTAC switches. The fixed TPU bumper cushions the last few millimeters of travel but is not adjustable; for heavy tooling at high speeds, add external shock absorption or meter-out the exhaust.
