Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X25R
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X25R 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, 25mm stroke; the return spring resets the rod when air is released.

About the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X25R
The AirTAC PSBR10X25R is a JIS pen-size single-acting push cylinder with a 10mm bore and 25mm stroke. Air entering the M5x0.8 port extends the rod, while an internal spring retracts it on air release. This single-line design is fail-safe retracted on air loss. You get about 29.8 N of net push at 0.5 MPa, with a maximum of 45.5 N at 0.7 MPa. The return spring sets a 0.2 MPa minimum pressure before motion begins.
This mini actuator features a SUS316L stainless barrel and a slim profile for tight jigs. The direct M4x0.7 front-cover mounting thread bolts straight to your fixture, eliminating extra brackets. A fixed TPU bumper decelerates the rod at stroke ends. The thin Ø4 mm rod handles coaxial thrust; add an external guide for any off-axis loads.

| Model | Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X25R |
|---|---|
| Series | PSBR JIS pen-size front-mount cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Stroke | 25 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 PSBR10X25R Is Used
Panel Pusher
Uses the 29.8 N net push to index light panels. The direct M4x0.7 front mount threads into tight machine frames.
Part Ejector
Spring retract drops the rod clear on air loss. The R axial inlet keeps plumbing flush for conveyor edges.
Clamp Release
Single-acting push holds a clamp open under power; the spring safely closes it when air drops.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X25R the Right Cylinder?
This 10mm bore provides 29.8 N net push at 0.5 MPa. Stepping down to the Ø8 bore drops the usable push to 18.7 N, while the larger Ø12 bore raises it to 42.9 N. The fail-safe retract and direct front mount suit compact ejection tasks.
Confirm your ordering essentials: this PSBR10X25R variant has an R axial inlet for inline plumbing and no built-in magnet. It uses an M5x0.8 air port and an M4x0.7 front-mount thread. The fixed TPU bumper handles light loads; meter-out the exhaust or add an external shock absorber if cycling faster with heavy tooling.
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 PSBR10X25R FAQ
The net push force is 29.8 N at 0.5 MPa and 45.5 N at the 0.7 MPa maximum. Because it is single-acting push with a return spring, a minimum pressure of 0.2 MPa is required before the rod moves.
It mounts directly via an M4x0.7 thread on the front cover, separate from the M5x0.8 air port. The barrel is SUS316L stainless steel, and this specific model has no magnet and an R axial air inlet.
