Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X50SU
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X50SU 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 PSBR16X50SU
The AirTAC PSBR16X50SU is a JIS pen-size single-acting push cylinder with a 50 mm stroke. Air entering the M5x0.8 port extends the rod to provide 74.8 N of net push at 0.5 MPa, while an internal spring retracts the rod for fail-safe operation. The SUS316L stainless barrel shrinks the envelope for tight jigs.
You bolt this unit straight to a fixture via the direct M5x0.8 front-cover thread, eliminating extra brackets. A fixed TPU bumper decelerates the rod at travel ends. Because the return spring sets a minimum pressure of 0.2 MPa, plan your air supply accordingly to ensure reliable motion.

|---|---|
| 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 PSBR16X50SU Is Used
Part Ejection
Uses the 74.8 N push stroke to eject machined components from a fixture, with the spring ensuring the arm retracts clear on air loss.
Panel Pusher
Bolts directly via the M5x0.8 front-cover thread to push lightweight panels into a locating rail without needing a separate bracket.
Clamp Release
Applies forward thrust to release a secondary clamp in a packaging line, relying on the fail-safe retract to secure the clamp during an outage.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X50SU the Right Cylinder?
This 16 mm bore generates 74.8 N net push at 0.5 MPa and 115 N at the 0.7 MPa maximum. Stepping down to a 12 mm bore drops the 0.5 MPa force to 42.9 N, while this 16 mm unit offers the highest thrust in the series. The internal spring guarantees the rod stays retracted if air pressure drops.
For sizing, target a safe working load of about 45 N, which is roughly 60 percent of the 0.5 MPa rating to account for seal friction. This equates to lifting about 3.8 kg vertically with a sane 2:1 margin. The U suffix provides a 90-degree side air inlet for flat plumbing, and the S suffix adds a piston magnet for reed or electronic switches.
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 PSBR16X50SU FAQ
It delivers 74.8 N of net push at 0.5 MPa and 115 N at the 0.7 MPa maximum. The internal return spring requires a minimum pressure of 0.2 MPa before the rod can extend, and the spring pulls the rod back to a fail-safe retracted position on air loss.
The unit bolts directly to a fixture using the M5x0.8 front-cover thread. The SUS316L stainless barrel suits damp environments, and the S suffix indicates a built-in piston magnet that works with reed or electronic switches for position sensing.
