Airtac PSB Single Acting Compact Cylinder PSB16X45SCB
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB16X45SCB 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 PSB16X45SCB
The AirTAC PSB16X45SCB is a single-acting push cylinder that uses one air line to extend the rod and an internal spring to retract it safely upon exhaust. It provides 74.8 N of net push at 0.5 MPa and 115 N at the 0.7 MPa maximum. The CB double clevis back cover accommodates pivoting loads.
This JIS pen-size mini body uses an M5x0.8 port and a fixed TPU bumper at each end to soften end-of-stroke impact. The built-in -S magnet supports reed or electronic switches. Plan for a safe working load of roughly 45 N, which accounts for friction and smooth travel.
Airtac PSB Single Acting Compact Cylinder PSB16X45SCB Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB16X45SCB |
|---|---|
| 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 PSB16X45SCB Is Used
Pivoting Part Ejector
Uses the CB clevis to swing and push finished plastic parts off a conveyor belt, relying on the spring to safely retract the rod when air pressure drops.
Carton Flap Folder
Extends to fold packaging flaps on a filling line, with the single air line simplifying valve requirements while the bumper absorbs the stroke impact.
Fail-Safe Clamp Release
Holds a workpiece during machining; the spring-return design guarantees the clamp retracts to a safe position if the factory air supply is interrupted.
Is the Airtac PSB Single Acting Compact Cylinder PSB16X45SCB the Right Cylinder?
This 16 mm bore generates 74.8 N net push at 0.5 MPa. Sizing down, the 12 mm bore yields 42.9 N; sizing up is not available as this is the largest pen-size option. The internal spring demands a minimum 0.2 MPa to overcome its return force and move the rod.
The Ø5 mm rod handles coaxial thrust well, but over the 45 mm stroke you should add an external guide for any off-axis loads. Confirm your ordering essentials: 16 mm bore, 45 mm stroke, S magnet, CB double clevis, and any mounting bracket.
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 PSB16X45SCB FAQ
It delivers 74.8 N net push at 0.5 MPa and 115 N at 0.7 MPa. Because the internal return spring opposes the air stroke, a minimum operating pressure of 0.2 MPa is required before the rod begins to move.
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 for reed or electronic switches.
