Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X30R
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X30R is a single acting, push type (spring return) pen-size mini cylinder with direct front-cover mounting (M5×0.8 thread). A single air port drives the push stroke on a Ø16mm bore, 30mm stroke; the return spring resets the rod when air is released.

About the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X30R
The AirTAC PSBR16X30R is a JIS pen-size single-acting push cylinder with a 16mm bore and 30mm stroke. It provides 74.8N net push at 0.5MPa and 115N at 0.7MPa. A return spring brings the rod home safely when air stops, making it fail-safe retracted. The slim SUS316L stainless body has a fixed TPU bumper and an R axial inlet for inline plumbing.
You bolt this actuator straight to a fixture via the direct front-cover M5x0.8 thread, eliminating extra brackets. Air enters the M5x0.8 port to extend the rod. Plan for a safe working load of about 45N (roughly 60% of the 0.5MPa figure) to account for seal friction and smooth travel.

|---|---|
| Series | PSBR JIS pen-size front-mount cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Stroke | 30 mm |
| Acting type | Single acting, push type (spring return) |
| Front-mount thread | M5×0.8 |
| Port size | M5×0.8 |
|---|---|
| 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 100 mm |
The spring holds the rod retracted; applying air pushes the rod out, and removing air lets the spring return it. Front cover carries the mounting thread (M5×0.8); barrel is SUS316L. Forces below are NET spring-deducted values. Confirm against the product label.
Net Push Force (Ø16mm)
| Pressure | Net push force |
|---|---|
| 0.5 MPa | 74.8 N |
| 0.7 MPa (max) | 115.0 N |
These are usable push forces after the return spring is subtracted, 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 PSBR Single Acting Square Head Compact Cylinder PSBR16X30R Is Used
Part Ejector
Uses the spring-return push to eject machined parts from a fixture, ensuring the arm safely retracts if air pressure drops.
Panel Pusher
Bolts directly via the front M5x0.8 thread to push lightweight panels into a nesting area within a compact jig.
Clamp Release
Applies 74.8N net push at 0.5MPa to hold a workpiece, with the spring automatically opening the clamp on air loss.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X30R the Right Cylinder?
This 16mm bore yields 74.8N net push at 0.5MPa. If you need less force, the 12mm bore gives 42.9N at the same pressure. If you require more power, 16mm is the largest available in this series, so you would need to step up to a different body profile. The internal spring sets a 0.2MPa minimum pressure before the rod moves.
The single solenoid line simplifies wiring, and the direct M5x0.8 front-mount thread secures the cylinder without a separate bracket. The thin 5mm rod handles coaxial thrust well, but over long strokes or off-axis loads you should add an external linear bearing to prevent side load damage. This specific configuration includes an R axial inlet and no sensor magnet.
Quick checklist
- ✓ Net push force at your working pressure
- ✓ Bolt directly through the front cover (M5×0.8)
- ✓ Only one air line / solenoid needed
- ✓ Fail-safe retract on air loss
- ✓ Magnet (S) for sensors?
- ✓ Stroke ≤ 100 mm (single-acting limit)
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 Match bolt size and engagement to the front thread.
- check Do not add an external return mechanism.
- check Keep the load coaxial; avoid side load on the thin rod.
Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X30R FAQ
The net push force is 74.8N at 0.5MPa and 115N at 0.7MPa. Because it is single-acting push with a return spring, it requires a minimum pressure of 0.2MPa to overcome the spring before the rod moves, and it fails safe to the retracted position on air loss.
The cylinder bolts directly to your fixture using the M5x0.8 front-cover thread, saving space without extra brackets. The SUS316L stainless barrel provides excellent corrosion resistance for damp or washdown environments, and the fixed TPU bumper decelerates the rod at the end of stroke.
