Airtac PSB Single Acting Compact Cylinder PSB16X45R
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB16X45R is a single acting, push type (spring return) pen-size mini cylinder with a Ø16mm bore and 45mm 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 PSB16X45R
The AirTAC PSB16X45R is a JIS pen-size single-acting push cylinder, meaning air entering its M5x0.8 port extends the rod while an internal spring retracts it upon exhaust. This single-line operation cuts tubing complexity and ensures the rod springs safely back home if air pressure drops. It supplies 74.8 N of net push at 0.5 MPa and 115 N at the 0.7 MPa maximum.
Built with a SUS304 stainless barrel and a slender Ø5 mm rod, this unit fits cramped jigs and light end-of-arm tooling. It relies on a fixed TPU bumper to soften the final few millimeters of travel. For smooth operation, plan for a safe working load of roughly 45 N, which accounts for seal friction and smooth motion.
Airtac PSB Single Acting Compact Cylinder PSB16X45R Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB16X45R |
|---|---|
| Series | PSB JIS pen-size mini cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Stroke | 45 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 PSB16X45R Is Used
Stamping Ejector
Pushes formed metal parts out of a press die. The spring-return design guarantees the ejector pin clears the mold cavity when the air supply stops.
Package Diverter
Acts as a sorting gate on a packaging line to push cartons onto a secondary belt. Fail-safe retraction keeps the main lane unobstructed during power loss.
Clamp Release
Applies 45 N of safe holding force to secure a workpiece on an assembly fixture, then releases the part instantly when the single solenoid valve exhausts.
Is the Airtac PSB Single Acting Compact Cylinder PSB16X45R the Right Cylinder?
This 16 mm bore generates 74.8 N net push at 0.5 MPa. If your task needs less force, the 12 mm bore yields 42.9 N at that same pressure, whereas stepping up is impossible as 16 mm is the largest pen-size option in this family. Remember the internal spring demands a minimum 0.2 MPa operating pressure before the piston can move. Confirm your ordering code covers the 45 mm stroke, axial R inlet, and any required LB, FA, or CJ mounting brackets.
Because the rod is only 5 mm thick, it handles coaxial thrust well but risks bending under off-axis loads over its 45 mm stroke. Add an external linear bearing if your assembly imposes side loads. The non-adjustable TPU bumper decelerates lightly loaded tooling, but at high cycling speeds you should 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 PSB16X45R FAQ
It provides 74.8 N of net push at 0.5 MPa and 115 N at 0.7 MPa. The internal return spring requires a minimum of 0.2 MPa to overcome spring tension and extend the rod. If air loss occurs, the spring pulls the rod back to a safe retracted position.
This model uses a fixed TPU bumper at each end to decelerate the piston over the last few millimeters of travel. It is not adjustable, so at high speeds with heavy tooling you should meter-out the exhaust or add an external shock absorber. This specific unit lacks a magnetic piston, so position sensing is not supported.
