Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X40R
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X40R 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, 40mm stroke; the return spring resets the rod when air is released.

About the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X40R
The AirTAC PSBR16X40R is a JIS pen-size single-acting push cylinder with a 16mm bore and 40mm stroke. Air entering the M5x0.8 port extends the rod, while an internal spring retracts it on air release. This fail-safe design keeps the rod retracted during pressure loss, requiring only one solenoid line. It delivers 74.8N of net push at 0.5 MPa and 115N at 0.7 MPa.
The direct M5x0.8 front-cover mounting thread bolts straight to your fixture, saving space in tight assemblies. The SUS316L stainless barrel suits damp environments, and a fixed TPU bumper cushions the stroke ends. The thin Ø5mm rod is built for coaxial thrust, so add an external guide for off-axis loads. For smooth operation, plan for a safe working load of about 45N, which is roughly 60% of the 0.5MPa rating.

|---|---|
| Series | PSBR JIS pen-size front-mount cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Stroke | 40 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 PSBR16X40R Is Used
Part Ejection
Uses the spring-return push to eject machined parts from a chute. The fail-safe retract ensures the ejector clears the workspace if air pressure drops suddenly.
Panel Pusher
Extends to push lightweight panels into a testing jig. The direct front-cover thread mounts flush to the machine frame, minimizing the footprint.
Clamp Release
Applies 74.8N net push at 0.5MPa to open a spring-loaded clamp. The SUS316L barrel withstands washdown environments in food packaging lines.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X40R the Right Cylinder?
This 16mm bore provides 74.8N net push at 0.5 MPa. Stepping down to a 12mm bore drops the usable push to 42.9N, while this 16mm model maxes out at 115N at 0.7 MPa. Choose this size when your fixture needs that extra thrust margin within a slim pen-size body.
Confirm the direct M5x0.8 front-mount thread matches your bolt engagement, especially for bottom mounting. The R axial inlet keeps plumbing in-line. Remember the internal spring sets a 0.2MPa minimum pressure before motion begins. No magnet is fitted on this variant.
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 PSBR16X40R FAQ
The net push force is 74.8N at 0.5MPa and 115N at 0.7MPa. Because it is single-acting push with a return spring, a minimum pressure of 0.2MPa is required before the rod moves. The rod fails safe to the retracted position on air loss.
It mounts directly via an M5x0.8 front-cover thread, eliminating separate brackets. The barrel is made of SUS316L stainless steel for corrosion resistance. It uses an R axial air inlet and has no built-in magnet.
