Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X80R
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X80R 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 PSBR16X80R
The AirTAC PSBR16X80R is a single-acting push pen-size mini cylinder with an 80mm stroke. Air entering the M5x0.8 port extends the rod, while an internal spring retracts it. This fail-safe design ensures the rod returns home on air loss. It delivers 74.8N of net push at 0.5 MPa and 115N at 0.7 MPa.
The SUS316L stainless barrel suits damp environments, and the direct M5x0.8 front-cover mounting thread bolts straight to your fixture. A fixed TPU bumper decelerates the stroke end. For this 80mm stroke, the slim Ø5mm rod handles coaxial thrust, so add an external guide for off-axis loads.
Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X80R Technical Specifications
| Model | Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X80R |
|---|---|
| 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 PSBR16X80R Is Used
Part Ejector
Pushes machined components out of a fixture using 74.8N net force, with the spring ensuring the ejector pin retracts safely when air pressure drops.
Lane Diverter
Direct M5x0.8 front-mount thread secures the cylinder to a conveyor side rail, extending to deflect parts onto a secondary belt before retracting.
Clamp Release
Overcomes a mechanical latch to release a held panel, relying on the fail-safe retract feature to keep the clamp closed during an air supply failure.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X80R the Right Cylinder?
This 16mm bore provides 74.8N net push at 0.5 MPa. Stepping down, the 12mm bore yields 42.9N. If you need powered extension and retraction, choose the PBR double-acting series; for a pull-type spring return, use PTBR. The R suffix specifies an axial air inlet for in-line plumbing.
Plan for a safe working load of about 45N, which is roughly 60% of the 0.5 MPa figure, to account for seal friction. This equates to lifting about 3.8kg vertically with a 2:1 margin. The internal spring requires a minimum 0.2 MPa 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 PSBR16X80R FAQ
The net usable push force is 74.8N at 0.5 MPa and 115N at the 0.7 MPa maximum. Because it is spring-return, the internal spring sets a 0.2 MPa minimum pressure required before the rod can extend.
It mounts directly via the M5x0.8 thread on the front cover, eliminating separate brackets. The R suffix indicates an axial back cover inlet for in-line air plumbing. The SUS316L stainless barrel provides corrosion resistance.
