Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X50U
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X50U 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, 50mm stroke; the return spring resets the rod when air is released.

About the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X50U
The AirTAC PSBR16X50U is a single-acting push pen cylinder that extends via one M5x0.8 air port and retracts via an internal spring. It provides 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 retracted on air loss, simplifying wiring to one solenoid line.
A direct M5x0.8 front-cover thread mounts the slim SUS316L stainless body straight to your fixture. The fixed TPU bumper decelerates the rod near stroke end. For smooth travel, 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 | 50 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 PSBR16X50U Is Used
Part Ejector
Pushes machined parts off a conveyor line with 74.8 N net force, relying on the spring to retract safely when air pressure drops.
Panel Pusher
Extends 50 mm to index lightweight panels using the direct front-cover thread for tight jig integration and minimal footprint.
Clamp Release
Overrides a mechanical latch to release a clamped workpiece, with the fail-safe retract ensuring the clamp stays locked on air loss.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X50U the Right Cylinder?
This 16 mm bore with a 50 mm stroke sits at the top of the PSBR range, offering the highest net thrust. If sizing down, the 12 mm bore yields 42.9 N of net push at 0.5 MPa. Because 16 mm is the largest available, heavier loads require a different cylinder family. The internal spring sets a 0.2 MPa minimum pressure before motion begins.
The U suffix provides a 90-degree side air inlet for flat plumbing. The direct front-cover M5x0.8 thread bolts straight to the jig, so confirm your thread engagement. The thin 5 mm rod handles coaxial thrust well, but over this 50 mm stroke you should add an external guide for any off-axis loads.
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 PSBR16X50U FAQ
It delivers 74.8 N of net push at 0.5 MPa and 115 N at the 0.7 MPa maximum. The return spring requires a minimum 0.2 MPa of air pressure to extend the rod, and the cylinder fails safe to the retracted position on air loss.
It mounts directly via an M5x0.8 thread on the front cover, eliminating separate brackets. The slim pen-size barrel is made of SUS316L stainless steel for durability in damp environments, and the U suffix denotes a 90-degree side air inlet.
