Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X80U
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X80U 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 PSBR16X80U
The AirTAC PSBR16X80U is a single-acting push pen cylinder that extends via one M5x0.8 air port and retracts automatically via a return spring. It supplies 74.8 N of net push at 0.5 MPa, climbing to 115 N at the 0.7 MPa maximum. If air pressure drops, the spring holds the rod safely retracted.
A direct M5x0.8 front-cover mounting thread bolts the slim SUS316L stainless body straight to your fixture. The fixed TPU bumper decelerates the stroke near the end of travel. With an 80 mm stroke, the slim Ø5 mm rod is built for coaxial thrust, so add an external guide for any off-axis loads.

| 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 PSBR16X80U Is Used
Part Ejector
Pushes machined parts off a conveyor line with 74.8 N net force, relying on the spring to retract the rod safely when air is cut.
Panel Pusher
Extends 80 mm to index lightweight panels using the direct front-cover thread for tight jig integration.
Clamp Release
Overrides a mechanical clamp with a compact 16 mm pen body, returning to the home position automatically via the internal spring.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X80U the Right Cylinder?
This 16 mm bore yields 74.8 N net push at 0.5 MPa. Stepping down, a 12 mm bore provides 42.9 N. Stepping up is not possible as 16 mm is the largest pen size. Plan for a safe working load of about 45 N, which is roughly 60 percent of the 0.5 MPa figure, to account for seal friction.
The return spring sets a 0.2 MPa minimum pressure before the rod moves. The U suffix denotes a 90-degree side inlet for flat plumbing. The direct front-mount thread eliminates extra brackets, and the fail-safe spring ensures a retracted state on air loss.
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 PSBR16X80U FAQ
The net push force is 74.8 N at 0.5 MPa and 115 N at the 0.7 MPa maximum. Because the internal return spring resists motion, a minimum pressure of 0.2 MPa is required before the rod extends. The spring ensures fail-safe retraction upon air loss.
It mounts directly via an M5x0.8 thread on the front cover, eliminating separate brackets. The U suffix indicates a 90-degree side air inlet on the back cover for flat hose routing. The SUS316L stainless barrel suits damp environments.
