Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X25R
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X25R 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 PSBR16X25R
The AirTAC PSBR16X25R is a single-acting push pen cylinder that delivers 74.8 N of net push at 0.5 MPa. Air entering the M5x0.8 port extends the rod, while an internal spring retracts it automatically. Because the spring holds the rod retracted on air loss, the actuator is fail-safe and requires only one solenoid line.
This 16 mm bore unit bolts straight to a fixture via its direct M5x0.8 front-cover thread, eliminating extra brackets. The SUS316L stainless barrel shrinks the footprint for tight jigs. A fixed TPU bumper decelerates the rod near 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 PSBR16X25R Is Used
Part Ejector
Pushes machined pins out of a chuck using 74.8 N net force, with the spring retracting the rod safely when air drops.
Panel Pusher
Indexes light electronic panels forward on a conveyor using the direct M5x0.8 front-mount thread to save assembly space.
Clamp Release
Overrides a mechanical latch to free a carton on a packaging line, relying on the fail-safe retracted hold.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X25R the Right Cylinder?
For lighter tasks, the 12 mm bore variant offers 42.9 N net push at 0.5 MPa, while this 16 mm bore provides 74.8 N at the same pressure. If you need maximum thrust, this model reaches 115 N at the 0.7 MPa ceiling. The internal return spring sets a 0.2 MPa minimum pressure before motion begins.
The direct M5x0.8 front-cover mounting thread secures the body without a separate bracket. This specific configuration includes an R axial inlet for inline plumbing and lacks a sensor magnet. The 25 mm stroke stays well within the 100 mm limit for this bore.
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 PSBR16X25R FAQ
The spring is already deducted, yielding 74.8 N net push at 0.5 MPa and 115 N at 0.7 MPa. The internal spring requires a 0.2 MPa minimum pressure to extend the rod.
The M5x0.8 front-cover thread bolts straight to your jig without extra brackets. The SUS316L stainless barrel provides a slim pen-size profile for compact tooling.
