Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X40R
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X40R 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, 40mm stroke; the return spring resets the rod when air is released.

About the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X40R
The AirTAC PSBR10X40R is a JIS pen-size single-acting push cylinder with a 40mm stroke. Air entering the M5x0.8 port extends the rod, while an internal spring retracts it. This fail-safe design ensures the rod returns home on air loss, requiring only one solenoid line. It delivers 29.8 N of net push at 0.5 MPa and 45.5 N at 0.7 MPa.
The SUS316L stainless barrel provides corrosion resistance for damp environments. You bolt this actuator straight to a fixture via the direct M4x0.7 front-cover thread, saving space. The fixed TPU bumper decelerates the rod at stroke ends.

|---|---|
| Series | PSBR JIS pen-size front-mount cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Stroke | 40 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 PSBR10X40R Is Used
Part Ejector
Pushes light machined components off a conveyor lane with 18 N of safe working force before spring-retracting for the next cycle.
Panel Pusher
Extends 40mm to index thin electronic panels into a test nest, using the direct M4x0.7 front thread to save fixture space.
Clamp Release
Overcomes a mechanical latch to release a clamped part, then failsafe retracts when air pressure drops to clear the workspace.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X40R the Right Cylinder?
This 10mm bore provides 29.8 N net push at 0.5 MPa. If you need less force, the 8mm bore offers 18.7 N. If your jig requires more power, step up to the 12mm bore yielding 42.9 N. The internal return spring sets a 0.2 MPa minimum pressure before motion begins.
The PSBR10X40R uses an R axial back cover inlet for inline plumbing. It lacks a sensor magnet. The thin 4mm rod handles coaxial thrust well, but over this 40mm stroke you should add an external guide to prevent side load binding.
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 PSBR10X40R FAQ
The net usable push force is 29.8 N at 0.5 MPa and 45.5 N at the 0.7 MPa maximum. Because it is spring-return, the internal spring sets a 0.2 MPa minimum pressure before the rod can extend. The rod failsafe retracts if air loss occurs.
It mounts directly via the M4x0.7 thread on the front cover, eliminating separate brackets. The R back cover provides an axial inline air inlet. The SUS316L stainless barrel suits damp environments, and this specific model lacks a sensor magnet.
