Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X30SR
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X30SR 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, 30mm stroke; the return spring resets the rod when air is released.

About the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X30SR
The AirTAC PSBR16X30SR is a single-acting push pen cylinder that extends via one M5x0.8 air port and retracts automatically via an internal spring. It yields 74.8 N of net push at 0.5 MPa, safely failing to a retracted position if air pressure drops. A built-in magnet enables position sensing with reed or electronic switches.
This 16 mm bore unit mounts directly via its front-cover M5x0.8 thread, eliminating extra brackets to save space. The SUS316L stainless barrel suits damp environments, while a fixed TPU bumper absorbs end-of-stroke impacts. For real-world sizing, plan for a safe working load of roughly 45 N, which equates to lifting about 3.8 kg vertically with a 2:1 margin.

|---|---|
| Series | PSBR JIS pen-size front-mount cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Stroke | 30 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 PSBR16X30SR Is Used
Part Ejection
Uses the spring-return push to eject machined components from a fixture, ensuring the arm safely retracts when air stops.
Panel Pusher
Direct front-mount M5x0.8 thread bolts right to a sub-plate to push lightweight panels into a machining nest.
Clamp Release
Applies 74.8 N net push at 0.5 MPa to hold a carton flap, then relies on the spring to withdraw the rod for cycle reset.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X30SR the Right Cylinder?
This 16 mm bore provides 74.8 N net push at 0.5 MPa and 115 N at the 0.7 MPa maximum. If you need less force, the 12 mm bore delivers 42.9 N at 0.5 MPa; for heavier tasks, this is the largest available pen size. The internal spring requires a minimum 0.2 MPa to move the rod.
The direct front-cover M5x0.8 thread secures the body straight to your fixture. The axial R back cover allows inline plumbing. Because the Ø5 mm rod is slender, add an external guide for off-axis loads over this 30 mm stroke.
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 PSBR16X30SR FAQ
The net push force is 74.8 N at 0.5 MPa and 115 N at the 0.7 MPa maximum. Because an internal spring returns the rod, a minimum pressure of 0.2 MPa is required before the piston extends, and the cylinder fails safe to the retracted position on air loss.
It mounts directly via the front-cover M5x0.8 thread. The -S suffix denotes a built-in piston magnet compatible with reed or electronic switches. The SUS316L stainless barrel provides corrosion resistance for damp environments.
