Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X75SU
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X75SU 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 PSBR16X75SU
The AirTAC PSBR16X75SU is a single-acting push pen cylinder with a 16mm bore and 75mm stroke. It delivers 74.8N of net push at 0.5 MPa and 115N at the 0.7 MPa maximum. A built-in return spring brings the rod home safely on air loss, making it fail-safe retracted. The SUS316L stainless barrel shrinks the footprint for tight jigs.
You bolt directly via the front-cover M5x0.8 thread, eliminating extra brackets. Air enters the M5x0.8 port to extend the rod, while the U suffix adds a 90-degree side inlet for flat plumbing. The S suffix provides a piston magnet for reed or electronic switches. A fixed TPU bumper cushions the stroke ends.

| 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 PSBR16X75SU Is Used
Part Ejection
Uses the 74.8N push to eject machined parts from a fixture, with the spring safely retracting the rod when air drops.
Panel Pusher
Bolts directly via the M5x0.8 front thread to push lightweight panels into a test jig without needing a separate bracket.
Clamp Release
Applies single-acting push to hold a carton flap, then releases automatically on air loss to prevent tearing.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X75SU the Right Cylinder?
This 16mm bore yields 74.8N net push at 0.5 MPa. Sizing both ways: stepping down to 12mm gives 42.9N, and since 16mm is the largest pen size, moving up requires a different body family. Plan for a safe working load of about 45N, which is roughly 60% of the 0.5 MPa figure to account for seal friction.
The internal spring sets a 0.2 MPa minimum pressure before motion. With a 2:1 margin, expect to lift about 3.8 kg vertically. The thin Ø5 mm rod handles coaxial thrust well, but over this 75mm stroke add an external linear bearing for any off-axis loads. Confirm the M5x0.8 front-mount thread matches your fixture.
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 PSBR16X75SU FAQ
The net push force is 74.8N at 0.5 MPa and 115N at the 0.7 MPa maximum. Because it is spring-return, a minimum pressure of 0.2 MPa is required to overcome the spring before the rod moves.
It mounts directly via an M5x0.8 front-cover thread. The SUS316L barrel resists damp environments, and the built-in S magnet works with reed or electronic switches for position sensing.
