Airtac PSB Single Acting Compact Cylinder PSB16X50CB
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB16X50CB 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 PSB16X50CB
The AirTAC PSB16X50CB is a JIS pen-size single-acting push cylinder with a 50 mm stroke and a CB double clevis back cover. 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 the 0.7 MPa maximum.
Built with a SUS304 stainless barrel and a slim mini body, it fits tight jigs and light end-of-arm tooling. A fixed TPU bumper cushions the stroke ends. For a safe working load, plan for about 45 N of real work, which is roughly 60 percent of the 0.5 MPa rating. The CB clevis accommodates pivoting loads, and the M10x1.0 rod-end thread simplifies tooling attachment.
Airtac PSB Single Acting Compact Cylinder PSB16X50CB Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB16X50CB |
|---|---|
| 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 PSB16X50CB Is Used
Pivoting Part Diverter
Uses the CB double clevis to swing a gate on a packaging line, pushing items to a secondary lane with 74.8 N of force at 0.5 MPa.
Fail-Safe Clamp Release
Secures an aluminum extrusion during machining. The spring safely retracts the clamp on air loss, preventing part or machine damage.
Lightweight Vertical Lift
Elevates small electronic components. With a 2:1 safety margin, it lifts about 3.8 kg vertically, matching real part weights for smooth travel.
Is the Airtac PSB Single Acting Compact Cylinder PSB16X50CB the Right Cylinder?
This 16 mm bore provides the highest net push in the PSB series, stepping up from the 12 mm bore which yields 42.9 N at 0.5 MPa. Since 16 mm is the largest available pen-size option, applications requiring more force must switch to a larger non-pen body. The internal return spring sets a 0.2 MPa minimum pressure before motion begins. Confirm your ordering essentials: 16 mm bore, 50 mm stroke, CB double clevis inlet, and no magnet.
Because the rod is only Ø5 mm, the 50 mm stroke demands an external guide or linear bearing to prevent side-loading damage. The fixed TPU bumper only decelerates the last few millimeters. At higher cycling speeds with heavy tooling mass, it bottoms out, so meter-out the exhaust or add 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 PSB16X50CB FAQ
The net usable push force is 74.8 N at 0.5 MPa and 115 N at the 0.7 MPa maximum. The internal return spring requires a minimum of 0.2 MPa before the rod can extend, and it fail-safe retracts the rod upon air loss.
It uses a fixed TPU bumper at each end to decelerate the last few millimeters of travel. The CB back cover is a double clevis designed for pivoting loads. At high speeds with real mass, meter-out the exhaust or add an external shock absorber.
