Airtac PSB Single Acting Compact Cylinder PSB16X50SR
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB16X50SR 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 PSB16X50SR
The AirTAC PSB16X50SR is a 16 mm bore, single-acting push pen cylinder with a 50 mm stroke. Air entering the single M5x0.8 port extends the Ø5 mm rod against an internal return spring, yielding 74.8 N of net push at 0.5 MPa and 115 N at 0.7 MPa. Because the spring constantly opposes the air stroke, these figures represent the true usable force after spring deduction. The slim SUS304 stainless body and axial R inlet plumbing make it ideal for cramped jigs.
This model includes a built-in piston magnet (S suffix) for position sensing with reed or electronic switches. It features a fixed TPU bumper at each end to soften end-of-stroke impact. Without live air, the internal spring provides a fail-safe retract, pulling the rod back to its home position automatically.
Airtac PSB Single Acting Compact Cylinder PSB16X50SR Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB16X50SR |
|---|---|
| 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 PSB16X50SR Is Used
Part Ejection
Uses the spring-return push to eject machined aluminum parts from a CNC fixture, ensuring the rod safely retracts if air pressure drops.
Gate Diversion
Acts as a sorting gate pusher on a packaging conveyor, extending to divert cardboard cartons and springing back to clear the line.
Clamp Release
Provides single-line clamping pressure for lightweight woodwork assembly, holding components while glue sets before releasing on exhaust.
Is the Airtac PSB Single Acting Compact Cylinder PSB16X50SR the Right Cylinder?
Selecting this 16 mm bore provides the maximum push force in the PSB family, stepping up from the Ø12 bore which offers 42.9 N of net push at 0.5 MPa. Plan for a safe working load of about 45 N (roughly 60 percent of the 74.8 N rating) to account for seal friction and smooth travel. In vertical lift applications, this translates to lifting about 3.8 kg with a sane 2:1 safety margin. A minimum operating pressure of 0.2 MPa is required to overcome the return spring before motion begins.
When ordering, confirm the 50 mm stroke, the S magnet option for switches, the R axial back cover inlet, and your mounting bracket choice. The thin Ø5 mm rod is designed for coaxial thrust; over this 50 mm stroke, add an external linear bearing if the application involves any off-axis loads to prevent rod binding.
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 PSB16X50SR FAQ
The net push force is 74.8 N at 0.5 MPa and 115 N at the 0.7 MPa maximum. Because an internal spring returns the rod, a minimum operating pressure of 0.2 MPa is required before the piston moves. The spring also ensures the rod fails safe retracted upon air loss.
This model uses a fixed TPU bumper at each end to decelerate the last few millimeters of travel; it is not adjustable, so meter-out the exhaust or add an external shock absorber if moving heavy tooling at high speeds. The S suffix indicates a built-in piston magnet compatible with AirTAC reed or electronic switches.
