Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X25U
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X25U 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 PSBR16X25U
The AirTAC PSBR16X25U is a single-acting push pen cylinder that extends via air pressure and retracts via an internal spring, ensuring a fail-safe home position on air loss. It supplies 74.8 N of net push at 0.5 MPa and 115 N at 0.7 MPa. A 90-degree side inlet keeps plumbing flat against your jig.
The direct M5x0.8 front-cover thread bolts straight to your fixture, saving space. The SUS316L stainless barrel suits damp environments, while a fixed TPU bumper cushions 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 | 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 PSBR16X25U Is Used
Part Ejector
Pushes machined pins out of a lathe collet. The spring retract pulls the rod back safely when air drops.
Panel Pusher
Slides a lightweight front plate into a test fixture using the direct front-cover thread for a flush mount.
Clamp Release
Overcomes a secondary latch to free a clamped part. The 90-degree side inlet eases hose routing.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X25U the Right Cylinder?
This 16mm bore provides 74.8 N net push at 0.5 MPa. Stepping down to a 12mm bore drops the output to 42.9 N, while moving up is unavailable within this pen-size format. The internal spring sets a 0.2 MPa minimum pressure before motion begins.
The rod is only 5mm thick, so add an external guide for off-axis loads over long strokes. The M5x0.8 air port feeds the extend chamber, and the M5x0.8 front-mount thread handles attachment. Confirm the U side-inlet fits your manifold layout.
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 PSBR16X25U FAQ
It delivers 74.8 N net push at 0.5 MPa and 115 N at 0.7 MPa. The return spring requires a minimum 0.2 MPa to extend the rod, and the cylinder fails safely retracted on air loss.
The M5x0.8 front-cover thread bolts directly to your bracket without extra hardware. The SUS316L stainless barrel resists corrosion, and the fixed TPU bumper decelerates the last few millimeters of travel.
