Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X30R
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X30R is a single acting, push type (spring return) pen-size mini cylinder with direct front-cover mounting (M4×0.7 thread). A single air port drives the push stroke on a Ø10mm bore, 30mm stroke; the return spring resets the rod when air is released.

About the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X30R
The AirTAC PSBR10X30R is a single-acting push-type pen cylinder featuring a 10 mm bore and 30 mm stroke. It supplies 29.8 N of net push at 0.5 MPa and 45.5 N at 0.7 MPa. A built-in return spring ensures the rod retracts automatically upon air loss, providing a fail-safe retracted state. The R suffix indicates an axial back cover inlet for streamlined in-line plumbing.
This model mounts directly via its front-cover M4x0.7 thread, eliminating extra brackets to save space in tight jigs. The SUS316L stainless barrel resists corrosion in damp environments. Air enters through the M5x0.8 port to extend the rod, while a fixed TPU bumper cushions the stroke ends. Plan for a safe working load of roughly 18 N, which accounts for seal friction and smooth travel.

|---|---|
| Series | PSBR JIS pen-size front-mount cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Stroke | 30 mm |
| Acting type | Single acting, push type (spring return) |
| Front-mount thread | M4×0.7 |
| 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 60 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 (M4×0.7); barrel is SUS316L. Forces below are NET spring-deducted values. Confirm against the product label.
Net Push Force (Ø10mm)
| Pressure | Net push force |
|---|---|
| 0.5 MPa | 29.8 N |
| 0.7 MPa (max) | 45.5 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 PSBR10X30R Is Used
Part Ejector
Pushes machined pins out of a chuck using 29.8 N net force. The spring-return design guarantees the ejector pin clears the workspace if air pressure drops.
Panel Pusher
Advances a lightweight electronic panel into a test socket. The direct M4x0.7 front mount threads directly into the slim test fixture without extra hardware.
Clamp Release
Overrides a mechanical latch to release a packaged component. The axial R inlet keeps pneumatic plumbing perfectly in line with the body.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X30R the Right Cylinder?
When sizing this spring-return unit, consider the adjacent bores. Dropping to the Ø8 version yields 18.7 N net push at 0.5 MPa, whereas stepping up to the Ø12 provides 42.9 N. This PSBR10X30R sits comfortably in the middle at 29.8 N, making it ideal for moderate ejection tasks. Remember the internal spring sets a 0.2 MPa minimum pressure before motion begins.
The direct M4x0.7 front-mount thread bolts straight to your fixture. Because the rod is a slender Ø4 mm, use an external guide or linear bearing for any off-axis loads. Confirm your ordering code specifies the R axial inlet and 30 mm stroke to match your assembly.
Quick checklist
- ✓ Net push force at your working pressure
- ✓ Bolt directly through the front cover (M4×0.7)
- ✓ Only one air line / solenoid needed
- ✓ Fail-safe retract on air loss
- ✓ Magnet (S) for sensors?
- ✓ Stroke ≤ 60 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 PSBR10X30R FAQ
The net push force is 29.8 N at 0.5 MPa and 45.5 N at 0.7 MPa. Because it is single-acting push with a return spring, there is a 0.2 MPa minimum pressure required before the rod can extend. The rod fails safe to the retracted position on air loss.
It mounts directly via an M4x0.7 thread on the front cover, which bolts straight into your jig. The barrel is constructed from SUS316L stainless steel for excellent corrosion resistance. Note that this specific model does not include a sensor magnet.
