Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X75U
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X75U 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 PSBR16X75U
The AirTAC PSBR16X75U is a single-acting push, spring-return pen cylinder featuring a direct M5x0.8 front-cover mounting thread. Air entering the M5x0.8 port extends the rod, while an internal spring retracts it on air loss, ensuring a fail-safe retracted position. It supplies 74.8 N of net push at 0.5 MPa and 115 N at the 0.7 MPa maximum.
The SUS316L stainless barrel suits damp environments, and the fixed TPU bumper decelerates the rod at stroke ends. For this 75 mm stroke, the 5 mm rod is built for coaxial thrust, so add an external guide if you have off-axis loads. 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 | 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 PSBR16X75U Is Used
Part Ejection
Uses the 74.8 N push stroke to eject machined parts from a fixture, with the spring safely pulling the rod back when air pressure drops.
Panel Pusher
Direct front-mount thread secures the slim body tightly to a sub-plate for pushing lightweight panels along an assembly line.
Clamp Release
Applies forward thrust to release a holding clamp, relying on the fail-safe retract design to prevent accidental clamping during an air supply failure.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X75U the Right Cylinder?
This 16 mm bore provides 74.8 N net push at 0.5 MPa. Stepping down to a 12 mm bore yields 42.9 N, while this 16 mm unit is the largest in the series, maxing out at 115 N at 0.7 MPa. Choose this model when you need higher force in a compact footprint.
The direct M5x0.8 front-mount thread bolts straight to your fixture, and the U suffix indicates a 90-degree side air inlet. The internal spring sets a 0.2 MPa minimum pressure before motion begins, and the rod fails safe to the retracted position on air loss.
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 PSBR16X75U FAQ
The net push force is 74.8 N at 0.5 MPa and 115 N at the 0.7 MPa maximum. Because it is a single-acting push cylinder with a return spring, it requires a minimum pressure of 0.2 MPa before the rod begins to move.
It mounts directly via an M5x0.8 thread on the front cover, eliminating the need for a separate bracket. The barrel is constructed from SUS316L stainless steel for durability in damp environments, and it features a fixed TPU bumper at each end.
