Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X15SR
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X15SR 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, 15mm stroke; the return spring resets the rod when air is released.

About the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X15SR
The AirTAC PSBR16X15SR is a single-acting push pen cylinder that uses air pressure to extend and an internal spring to retract. It provides 74.8 N of net push at 0.5 MPa and 115 N at 0.7 MPa. The return spring ensures the rod moves safely back to its home position on air loss.
This model features a built-in magnet for reed or electronic switches and an R axial inlet. The direct M5x0.8 front-cover thread bolts straight to your fixture, saving space. A fixed TPU bumper absorbs impact at the stroke ends. Plan for a safe working load of about 45 N, 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 | 15 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 PSBR16X15SR Is Used
Part Ejection
Uses the 74.8 N push stroke to eject machined components from a fixture, with the spring ensuring hands-free retraction.
Panel Pusher
Extends to index lightweight panels along a guide rail, relying on the direct front-mount thread for a compact footprint.
Clamp Release
Overcomes a holding mechanism to release a workpiece, returning to a safe retracted state if the air supply drops.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X15SR the Right Cylinder?
Selecting this 16 mm bore gives 74.8 N net push at 0.5 MPa. If you need less force, the 12 mm bore version yields 42.9 N. If you need more power, you exceed the 115 N maximum available at 0.7 MPa for this series. The M5x0.8 front-mount thread secures the body directly to your jig.
The M5x0.8 air port connects to one solenoid line. The internal spring sets a 0.2 MPa minimum pressure before motion begins. The slim SUS316L barrel is ideal for tight setups, and the thin 5 mm rod requires an external guide for off-axis loads.
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 PSBR16X15SR FAQ
It delivers 74.8 N of net push at 0.5 MPa and 115 N at 0.7 MPa. Because it is spring-return, a minimum pressure of 0.2 MPa is required to overcome the spring and extend the rod.
It mounts directly via the M5x0.8 thread on the front cover. The S option includes a built-in piston magnet compatible with reed or electronic switches. The SUS316L barrel suits damp environments.
