Airtac PSB Single Acting Compact Cylinder PSB16X5SR
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB16X5SR is a single acting, push type (spring return) pen-size mini cylinder with a Ø16mm bore and 5mm 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 PSB16X5SR
The AirTAC PSB16X5SR is a JIS pen-size single-acting push cylinder with a 5mm stroke. Air entering the M5x0.8 port extends the Ø5mm rod, while an internal spring retracts it upon exhaust. This fail-safe design ensures the rod returns home if air pressure drops, needing only one solenoid line for simpler tubing. It supplies 74.8N of net push at 0.5 MPa.
The SUS304 stainless barrel and slim body fit easily into tight jigs. A fixed TPU bumper decelerates the stroke at both ends. The built-in magnet (-S) supports reed or electronic switches for position sensing. Plan for a safe working load of about 45N, which is roughly 60 percent of the 0.5 MPa rating.
Airtac PSB Single Acting Compact Cylinder PSB16X5SR Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB16X5SR |
|---|---|
| Series | PSB JIS pen-size mini cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Stroke | 5 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 PSB16X5SR Is Used
Short-Stroke Part Ejector
Pushes finished metal pins out of a lathe collet in tight spaces, relying on the spring to retract instantly when air stops.
Carton Flap Tucker
Extends 5mm to fold small cardboard flaps on a packing line, safely returning home if the air supply fails.
Sensor Alignment Gate
Briefly pushes a part against a hard stop for a vision check, using the fail-safe retract to clear the area quickly.
Is the Airtac PSB Single Acting Compact Cylinder PSB16X5SR the Right Cylinder?
This 16mm bore provides 74.8N net push at 0.5 MPa and 115N at 0.7 MPa. If you need less force, the 12mm bore offers 42.9N at 0.5 MPa. Because the internal spring sets a 0.2 MPa minimum pressure before motion starts, ensure your supply can overcome it. The short 5mm stroke is ideal for compact ejection.
Ordering requires confirming the bore, stroke, magnet (S), and the R axial inlet. The Ø5mm rod handles coaxial thrust well, but avoid side loads. For vertical lifts, expect to raise about 3.8kg safely with a 2:1 margin.
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 PSB16X5SR FAQ
It delivers 74.8N of net push at 0.5 MPa and 115N at 0.7 MPa. The internal return spring requires a minimum operating pressure of 0.2 MPa before the rod moves. The spring automatically retracts the rod on air loss.
It uses a fixed TPU bumper to decelerate the stroke at the ends, which is not adjustable. The built-in magnet works with AirTAC reed or electronic switches. At high speeds with heavy tooling, meter-out the exhaust or add an external shock absorber.
