Airtac PSB Single Acting Compact Cylinder PSB16X35U
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB16X35U 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 PSB16X35U
The AirTAC PSB16X35U is a JIS pen-size single-acting push cylinder that extends its Ø5 mm rod using one air line, relying on a built-in spring to retract safely upon exhaust loss. It supplies 74.8 N of net push at 0.5 MPa and 115 N at the 0.7 MPa maximum. The U back cover provides a 90-degree side inlet for flat plumbing in tight spaces.
Built with a SUS304 stainless barrel and slim body, it carries a fixed TPU bumper at each end. Because the internal spring opposes extension, a minimum 0.2 MPa is required before motion begins. Plan for a safe working load of about 45 N, which is roughly 60 percent of the 0.5 MPa rating, to account for seal friction.
Airtac PSB Single Acting Compact Cylinder PSB16X35U Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB16X35U |
|---|---|
| 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 PSB16X35U Is Used
Part Ejector
Pushes machined pins off a conveyor belt; the spring safely pulls the rod back if the air supply drops.
Clamp Release
Holds a workpiece forward during machining, then exhausts to let the internal spring retract the rod for unloading.
Flap Folder
Extends to tuck carton flaps on a packaging line, using the 90-degree side inlet to keep tubing flush against the frame.
Is the Airtac PSB Single Acting Compact Cylinder PSB16X35U the Right Cylinder?
This 16 mm bore generates 74.8 N net push at 0.5 MPa. If you need less force, the 12 mm bore offers 42.9 N; stepping up is impossible as this is the largest diameter in the series. The 35 mm stroke fits well within the 60 mm single-acting limit. Remember the spring fail-safe retracts the rod home when air is removed. Confirm your ordering code details: bore, stroke, no magnet, U side inlet, and any 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 PSB16X35U FAQ
It provides a net push of 74.8 N at 0.5 MPa and 115 N at 0.7 MPa. The internal return spring requires a minimum of 0.2 MPa before the rod begins to move, and the rod fails safe to the retracted position on air loss.
It uses a fixed TPU bumper to decelerate the rod over the last few millimeters. At high speeds with real tooling mass, meter-out the exhaust or add an external shock absorber. The Ø5 mm rod is for coaxial thrust only, so add an external guide for off-axis loads.
