Airtac PSB Single Acting Compact Cylinder PSB16X45CB
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB16X45CB 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 PSB16X45CB
The AirTAC PSB16X45CB is a JIS pen-size single-acting push cylinder with a 45 mm stroke. Air entering the single M5x0.8 port extends the Ø5 mm rod, while an internal spring retracts it upon exhaust. This fail-safe design ensures the rod returns home if air pressure drops. It delivers 74.8 N of net push at 0.5 MPa and 115 N at 0.7 MPa.
Built with a SUS304 stainless barrel and a CB double clevis back cover, this unit accommodates pivoting loads. The fixed TPU bumper decelerates the stroke at each end. Plan for a safe working load of roughly 45 N, which accounts for seal friction and smooth travel.
Airtac PSB Single Acting Compact Cylinder PSB16X45CB Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB16X45CB |
|---|---|
| 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 PSB16X45CB Is Used
Pivoting Part Diverter
Uses the CB double clevis to swing a gate on a packaging line, pushing items onto an auxiliary belt with 74.8 N of force.
Fail-Safe Clamp Release
Holds a machined bracket during milling; the spring automatically retracts the rod on air loss to safely clear the workspace.
Lightweight Vertical Lift
Ejects finished molded parts upward, safely lifting components weighing about 3.8 kg with a standard 2:1 safety margin.
Is the Airtac PSB Single Acting Compact Cylinder PSB16X45CB the Right Cylinder?
This 16 mm bore generates 74.8 N net push at 0.5 MPa. If your application requires less force, the Ø12 bore provides 42.9 N at the same pressure; stepping up is not possible as Ø16 is the largest pen-size option in this series. A minimum of 0.2 MPa is required to overcome the return spring before motion begins.
Confirm your ordering essentials: 16 mm bore, 45 mm stroke, CB double clevis inlet, and no magnet. The thin Ø5 mm rod handles coaxial thrust well, but over this 45 mm stroke you should add an external guide to prevent side loading.
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 PSB16X45CB FAQ
The net push force is 74.8 N at 0.5 MPa and 115 N at 0.7 MPa (maximum pressure). Because an internal spring returns the rod, a minimum of 0.2 MPa is required before the cylinder can move.
It uses a fixed TPU bumper at each end to decelerate the rod over the last few millimeters. The bumper is not adjustable; at higher speeds with heavy tooling mass, meter-out the exhaust or add an external shock absorber.
