Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X75R
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X75R 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 PSBR16X75R
The AirTAC PSBR16X75R is a single-acting push, spring-return pen-size mini cylinder. Air entering the M5x0.8 port extends the rod, while an internal spring retracts it on air loss for fail-safe retraction. 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 or washdown environments.
You mount this actuator directly via its front-cover M5x0.8 thread, eliminating extra brackets to save space on light end-of-arm tooling. The fixed TPU bumper decelerates the rod near the end of its 75 mm travel. A built-in return spring sets a 0.2 MPa minimum pressure before motion begins. Plan for a safe working load of about 45 N, which is roughly 60 percent of the 0.5 MPa rating, to account for seal friction.

|---|---|
| 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 PSBR16X75R Is Used
Part Ejector
Uses the 74.8 N net push to eject machined components from a fixture, with the spring ensuring the rod retracts safely when air pressure drops.
Panel Pusher
Advances a lightweight panel along a conveyor guide, relying on the direct front-cover M5x0.8 thread to save space inside the machine frame.
Clamp Release
Overcomes a mechanical clamp spring to release a workpiece, using the axial R inlet to keep pneumatic plumbing neatly in line.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X75R the Right Cylinder?
Selecting this 16 mm bore over the smaller 12 mm size upgrades your net push from 42.9 N to 74.8 N at 0.5 MPa. If you need less force, the 12 mm option offers a slimmer profile. This 75 mm stroke sits well below the 100 mm limit for this bore. The thin Ø5 mm rod handles coaxial thrust well, but over this 75 mm length you should add an external linear bearing for any off-axis loads.
The direct front-cover M5x0.8 thread secures the body straight into your fixture. This R variant uses an axial air inlet for in-line plumbing. It lacks a sensor magnet, so choose a PBR double-acting cylinder if you need powered retraction or position feedback.
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 PSBR16X75R 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 spring-return, a minimum pressure of 0.2 MPa is required before the rod moves, and the spring holds the rod retracted on air loss.
It mounts directly via a front-cover M5x0.8 thread. The barrel is made of SUS316L stainless steel for durability in damp environments. This model has no sensor magnet and uses an axial R air inlet.
