Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X25SU
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X25SU 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, 25mm stroke; the return spring resets the rod when air is released.

About the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X25SU
The AirTAC PSBR16X25SU is a single-acting push pen cylinder that extends via one M5x0.8 air port and retracts via an internal spring. It delivers 74.8 N of net push at 0.5 MPa, rising to 115 N at the 0.7 MPa maximum. The fail-safe spring design ensures the rod pulls home on air loss, keeping wiring simple with just one solenoid line.
This 16mm bore model features a direct M5x0.8 front-cover mounting thread, allowing it to bolt straight onto your jig without extra brackets. The SUS316L stainless barrel suits damp environments, while a fixed TPU bumper cushions the stroke ends. A built-in magnet enables position sensing with reed or electronic switches.

|---|---|
| Series | PSBR JIS pen-size front-mount cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Stroke | 25 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 PSBR16X25SU Is Used
Part Ejector
Uses the spring-return push action to eject machined parts from a chuck. The direct front-mount thread secures it tightly to the machine bed.
Panel Pusher
Extends to push lightweight panels into a machining cell. The fail-safe retract guarantees the pusher clears the work area on air loss.
Clamp Release
Applies 74.8 N net push at 0.5 MPa to disengage a holding clamp. The 90-degree side inlet keeps the pneumatic plumbing compact.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X25SU the Right Cylinder?
This 16mm bore provides 74.8 N net push at 0.5 MPa. Sizing down, the 12mm bore yields 42.9 N; sizing up is not available as this is the largest in the series.
The direct front-cover M5x0.8 thread mounts flush to fixtures, and the U suffix adds a 90-degree side inlet for flat plumbing. The 5mm rod handles coaxial thrust well, but add an external guide for off-axis loads. Confirm your solenoid and switch type when ordering.
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 PSBR16X25SU 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 creates resistance, a minimum pressure of 0.2 MPa is required before the rod extends. The spring ensures the cylinder fails safe in the retracted position.
The S suffix indicates a built-in piston magnet compatible with reed or electronic switches. The U suffix provides a 90-degree side air inlet. It mounts directly via the M5x0.8 front-cover thread, and the SUS316L stainless barrel resists corrosion in damp environments.
