Airtac PSB Single Acting Compact Cylinder PSB16X35SU
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB16X35SU is a single acting, push type (spring return) pen-size mini cylinder with a Ø16mm bore and 35mm 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 PSB16X35SU
The AirTAC PSB16X35SU is a JIS pen-size single-acting push cylinder that extends via one M5x0.8 air line and retracts via a built-in return spring. It provides 74.8 N of net push at 0.5 MPa and 115 N at 0.7 MPa. The integrated spring ensures the rod safely pulls back to a fail-safe home position whenever exhaust occurs or air pressure drops.
Featuring a SUS304 stainless barrel and a slim body, it fits easily into tight jigs. This configuration includes a built-in piston magnet for position sensing and a U-style 90-degree side inlet for flat plumbing. The Ø5 mm rod has an M10x1.0 end thread. A fixed TPU bumper cushions the stroke ends, and plan for a safe working load of roughly 45 N to account for friction.
Airtac PSB Single Acting Compact Cylinder PSB16X35SU Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB16X35SU |
|---|---|
| Series | PSB JIS pen-size mini cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Stroke | 35 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 PSB16X35SU Is Used
Part Ejector
Pushes machined components off a conveyor lane; the spring guarantees the arm retracts clear of passing parts if the air supply fails.
Clamp Release
Applies 74.8 N of thrust at 0.5 MPa to hold a light workpiece, then releases automatically when air is removed.
Flap Folder
Extends to tuck carton flaps on a packaging line, utilizing the 90-degree side inlet to keep tubing flush against the machine frame.
Is the Airtac PSB Single Acting Compact Cylinder PSB16X35SU the Right Cylinder?
This 16 mm bore generates 74.8 N net push at 0.5 MPa. Stepping down to a 12 mm bore yields 42.9 N, while no larger single-acting option exists in this pen-size family. The internal spring requires a minimum of 0.2 MPa before motion begins. Plan for a vertical lift capacity of about 3.8 kg using a sane 2:1 safety margin.
Because the Ø5 mm rod is slender, add an external linear bearing for any off-axis loads over this 35 mm stroke. Confirm your ordering essentials: 16 mm bore, 35 mm stroke, S magnet, U side inlet, and your chosen mounting bracket.
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 PSB16X35SU FAQ
The net push force is 74.8 N at 0.5 MPa and 115 N at 0.7 MPa. Because an internal spring opposes the air stroke, a minimum pressure of 0.2 MPa is required to move the rod. The spring automatically retracts the rod on air loss.
Yes, the built-in S magnet works with both reed and electronic AirTAC switches. The fixed TPU bumper decelerates the rod over the last few millimeters of travel. For high-speed cycles with heavy tooling, meter-out the exhaust or add an external shock absorber.
