Airtac PSB Single Acting Compact Cylinder PSB16X15CB
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB16X15CB is a single acting, push type (spring return) pen-size mini cylinder with a Ø16mm bore and 15mm 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 PSB16X15CB
The AirTAC PSB16X15CB is a single-acting push cylinder with a built-in spring that retracts the rod upon air loss, ensuring a fail-safe home position for clamping or ejection tasks. It uses an M5x0.8 port and generates 74.8 N of net push force at 0.5 MPa. A single solenoid line drives the extension, simplifying tubing and cutting valve costs compared to double-acting units.
Built on a slim JIS pen-size body, the SUS304 stainless barrel and rod resist moisture in tight jigs. The CB double clevis accommodates pivoting loads, and a fixed TPU bumper cushions the stroke ends. Plan for a safe working load of roughly 45 N to account for seal friction and smooth travel.
Airtac PSB Single Acting Compact Cylinder PSB16X15CB Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB16X15CB |
|---|---|
| Series | PSB JIS pen-size mini cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Stroke | 15 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 PSB16X15CB Is Used
Pivoting Part Ejector
Uses the CB double clevis to swing and push finished metal parts off a machining center conveyor, relying on the spring to retract safely if air pressure drops.
Carton Flap Folder
Extends to fold corrugated cardboard flaps during case packing, with the spring-return design ensuring the mechanism retracts clear of the product flow.
Gate Diverter
Pushes a lightweight routing gate on an assembly line to sort components, using the fail-safe retract feature to open the default path during an outage.
Is the Airtac PSB Single Acting Compact Cylinder PSB16X15CB the Right Cylinder?
This 16 mm bore provides 74.8 N net push at 0.5 MPa (115 N at the 0.7 MPa maximum). If your task needs less force, the 12 mm bore yields 42.9 N at 0.5 MPa; for heavier work, this is the largest pen-size option available. The internal return spring requires at least 0.2 MPa before the rod moves. Confirm your ordering essentials: 16 mm bore, 15 mm stroke, CB double clevis, and no magnet.
The Ø5 mm rod handles coaxial thrust well, but over long strokes or off-axis loads you should add an external guide to prevent side load damage. The fixed TPU bumper only decelerates the last few millimeters, so at high speeds with real tooling mass, 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 PSB16X15CB FAQ
It delivers 74.8 N of net push at 0.5 MPa and 115 N at 0.7 MPa. Because an internal spring opposes the air stroke, a minimum of 0.2 MPa is required before the rod extends. The spring automatically retracts the rod when air is exhausted.
The CB back cover is a double clevis designed for pivoting mountings. Cushioning is handled by a fixed TPU bumper at each end that decelerates the last few millimeters of travel. It is not adjustable, so with heavy tooling mass at high speeds you should meter-out the exhaust or use an external shock absorber.
