Airtac PSB Single Acting Compact Cylinder PSB16X50SCB
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB16X50SCB is a single acting, push type (spring return) pen-size mini cylinder with a Ø16mm bore and 50mm 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 PSB16X50SCB
The AirTAC PSB16X50SCB is a JIS pen-size single-acting push cylinder featuring a 16 mm bore and 50 mm stroke. Air entering the single M5x0.8 port extends the Ø5 mm rod, while an internal spring ensures fail-safe retraction upon exhaust. You gain 74.8 N of net push at 0.5 MPa and 115 N at the 0.7 MPa maximum, making it ideal for simplified valving on light end-of-arm tooling.
This variant includes a built-in piston magnet for position sensing with reed or electronic switches, plus a CB double clevis back cover for pivoting mountings. The SUS304 stainless barrel and slim body fit tight jigs. It uses a fixed TPU bumper at each end to decelerate motion, and the M10x1.0 rod-end thread handles your tooling attachment.
Airtac PSB Single Acting Compact Cylinder PSB16X50SCB Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB16X50SCB |
|---|---|
| Series | PSB JIS pen-size mini cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Stroke | 50 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 PSB16X50SCB Is Used
Pivoting Part Ejector
Uses the CB double clevis to swing and push finished metal parts off a milling table, relying on the spring to safely retract the pin during air loss.
Package Gate Diverter
Extends to block or guide boxes on a packaging line, with the single air line simplifying tubing and reducing solenoid costs on the conveyor frame.
Clamp Release Mechanism
Applies 74.8 N of thrust at 0.5 MPa to hold a light workpiece, returning to a retracted state automatically when the pneumatic signal drops.
Is the Airtac PSB Single Acting Compact Cylinder PSB16X50SCB the Right Cylinder?
This 16 mm bore provides 74.8 N net push at 0.5 MPa. Sizing down, the 12 mm bore yields 42.9 N at the same pressure, offering a lighter alternative if your load permits. Because the internal spring sets a 0.2 MPa minimum operating pressure before motion begins, ensure your supply can overcome this threshold. The fail-safe retracted hold keeps parts released during air loss.
When ordering, confirm the 50 mm stroke, the S magnet option, and the CB double clevis inlet. For heavy tooling mass at high speeds, the fixed TPU bumper may bottom out; meter-out the exhaust or add an external shock absorber. Plan for a safe working load of about 45 N, which allows a smooth 2:1 vertical lift margin of roughly 3.8 kg.
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 PSB16X50SCB FAQ
The net push force is 74.8 N at 0.5 MPa and 115 N at 0.7 MPa. The internal return spring requires a minimum operating pressure of 0.2 MPa before the rod moves, and the cylinder fails safe to a retracted position on air loss.
The S suffix indicates a built-in piston magnet for reed or electronic switches. It uses a fixed TPU bumper at each end to decelerate the last few millimeters of travel; at high speeds with real mass, meter-out the exhaust or add an external shock absorber.
