Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X15SU
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X15SU 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, 15mm stroke; the return spring resets the rod when air is released.

About the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X15SU
The AirTAC PSBR16X15SU is a single-acting push pen cylinder that extends via one M5x0.8 air port and retracts via an internal spring. It delivers 74.8 N of net push at 0.5 MPa and 115 N at the 0.7 MPa maximum. The fail-safe spring holds the rod home on air loss, needing just one solenoid line.
A 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. The built-in magnet works with reed or electronic switches.

|---|---|
| Series | PSBR JIS pen-size front-mount cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Stroke | 15 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 PSBR16X15SU Is Used
Part Ejector
Pushes machined parts off a conveyor line with 74.8 N net force, retracting safely when air drops.
Panel Pusher
Extends 15mm to index lightweight panels, using the direct front thread to bolt directly into tight jig frames.
Clamp Release
Overcomes spring tension to release holding clamps, relying on the fail-safe retract to secure parts on air loss.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X15SU the Right Cylinder?
This 16mm bore provides 74.8 N net push at 0.5 MPa. Stepping down, the 12mm bore yields 42.9 N; stepping up is unavailable as 16mm is the largest in the series. Plan for a safe working load of about 45 N (roughly 60% of the 0.5 MPa figure) to account for seal friction.
The spring sets a 0.2 MPa minimum pressure before motion. The direct front-cover M5x0.8 thread mounts without extra brackets, and the U suffix provides a 90-degree side air inlet for flat plumbing.
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 PSBR16X15SU 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 0.2 MPa minimum pressure is required to overcome the spring and extend the rod.
It mounts directly via an M5x0.8 front-cover thread. The S suffix indicates a built-in piston magnet compatible with reed or electronic switches, and the SUS316L barrel resists corrosion in damp environments.
