Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X75SR
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X75SR 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, 75mm stroke; the return spring resets the rod when air is released.

About the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X75SR
The AirTAC PSBR16X75SR is a single-acting push pen cylinder that extends via one M5x0.8 air port and retracts automatically via an internal spring. It supplies 74.8 N of net push at 0.5 MPa, reaching 115 N at the 0.7 MPa maximum. If air pressure drops, the spring securely holds the rod retracted for a fail-safe state.
You bolt this 16mm bore unit straight to a fixture using the direct M5x0.8 front-cover thread. The SUS316L stainless barrel shrinks the footprint for compact jigs. A fixed TPU bumper cushions the stroke ends. Because the return spring sets a 0.2 MPa minimum operating pressure, plan for a safe working load of roughly 45 N 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 | 75 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 PSBR16X75SR Is Used
Part Ejector
Pushes machined components out of a tight fixture using the direct front mount, then springs back to clear the workspace.
Panel Diverter
Extends to deflect lightweight boards on a line and failsafe retracts on air loss to prevent conveyor jams.
Clamp Release
Overcomes holding force to unclamp parts, using the 45 N safe working load to free components reliably.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X75SR the Right Cylinder?
This 16mm bore provides 74.8 N net push at 0.5 MPa. Stepping down, a 12mm bore yields 42.9 N, while stepping up is unavailable as 16mm is the largest in the series. The 75mm stroke sits comfortably under the 100mm limit for this bore.
The direct M5x0.8 front-cover thread mounts without extra brackets. The thin Ø5 mm rod handles coaxial thrust well, but over this 75mm stroke you should add an external linear bearing for any off-axis loads. The built-in -S magnet supports reed or electronic switches, and the R axial inlet streamlines in-line plumbing.
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 PSBR16X75SR FAQ
It delivers 74.8 N net push at 0.5 MPa and 115 N at the 0.7 MPa maximum. The internal return spring requires a minimum 0.2 MPa operating pressure to extend the rod.
It mounts directly via an M5x0.8 front-cover thread, separate from the M5x0.8 air port. The slim body features a SUS316L stainless barrel, and the -S magnet works with reed or electronic switches.
