Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X80SU
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X80SU 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, 80mm stroke; the return spring resets the rod when air is released.

About the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X80SU
The AirTAC PSBR16X80SU is a single-acting push pen cylinder with an 80mm stroke. Air entering the M5x0.8 port extends the rod, while an internal spring retracts it automatically. You get 74.8N of net push at 0.5 MPa and 115N at the 0.7 MPa maximum. The fail-safe design holds the rod retracted on air loss.
This 16mm bore model features a built-in magnet for electronic or reed switches, plus a U 90-degree side inlet for flat plumbing. The direct front-cover M5x0.8 mounting thread bolts straight to your fixture, and the SUS316L stainless barrel handles damp environments. A fixed TPU bumper decelerates the stroke end. Plan for a safe working load of about 45N, which is roughly 60 percent of the 0.5 MPa rating.

|---|---|
| Series | PSBR JIS pen-size front-mount cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Stroke | 80 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 PSBR16X80SU Is Used
Part Ejection
Uses the 80mm stroke to push machined parts off a conveyor line, with the spring ensuring the arm clears the workspace on air loss.
Panel Pusher
Deploys the rod to index lightweight panels into a testing station, relying on the 74.8N net push at 0.5 MPa for smooth travel.
Clamp Release
Extends to relieve a holding fixture, where the single-acting design cuts solenoid wiring and guarantees the clamp engages when air stops.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X80SU the Right Cylinder?
At 80mm, this cylinder uses its full stroke efficiently while keeping a compact footprint. If you need less force, the 12mm bore yields 42.9N net push at 0.5 MPa. If you require more power, this 16mm bore is the largest in the series at 74.8N. The direct front-cover thread simplifies assembly, and the spring ensures a safe retract on air loss.
Confirm the M5x0.8 front-mount thread matches your bolt size. The 90-degree side inlet requires flat plumbing space. The internal return spring sets a 0.2 MPa minimum pressure before motion begins.
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 PSBR16X80SU FAQ
The net push force is 74.8N at 0.5 MPa and 115N at 0.7 MPa. Because it is spring-return, a minimum pressure of 0.2 MPa is required to overcome the spring and move the rod.
It mounts directly via an M5x0.8 front-cover thread. The S suffix indicates a built-in piston magnet for electronic or reed switches, and the SUS316L barrel suits corrosive environments.
