Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X50SU
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X50SU 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, 50mm stroke; the return spring resets the rod when air is released.

About the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X50SU
The AirTAC PSBR10X50SU is a JIS pen-size single-acting push cylinder with a 50 mm stroke. Air entering the M5x0.8 port extends the rod, while an internal spring retracts it on air loss for a fail-safe retracted hold. It supplies 29.8 N of net push at 0.5 MPa, reaching 45.5 N at the 0.7 MPa maximum.
You bolt this slim SUS316L stainless body straight to your jig via the direct M4x0.7 front-cover thread, eliminating separate brackets. A fixed TPU bumper decelerates the stroke ends. For smooth travel, plan for a safe working load of about 18 N, which lifts roughly 1.5 kg vertically with a 2:1 margin.
Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X50SU Technical Specifications

|---|---|
| Series | PSBR JIS pen-size front-mount cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Stroke | 50 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 PSBR10X50SU Is Used
Part Ejector
Pushes machined pins out of a fixture using the direct front-mount thread, relying on the spring to retract safely when air pressure drops.
Panel Separator
Protrudes 50 mm to index thin electronic panels along a conveyor, saving space with its slim SUS316L stainless pen-size body.
Clamp Release
Overrides a mechanical latch in tight assembly jigs, using the 90-degree side inlet to keep pneumatic plumbing flat against the machine frame.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X50SU the Right Cylinder?
This 10 mm bore outputs 29.8 N net push at 0.5 MPa. Stepping down to an 8 mm bore yields 18.7 N, while a 12 mm bore provides 42.9 N if you need more force. The direct M4x0.7 front mount and fail-safe spring return suit compact ejection tasks.
At 50 mm stroke, the slender Ø4 mm piston rod requires an external guide or linear bearing to prevent off-axis side load binding. The U suffix provides a 90-degree side air inlet for flat plumbing, and the S suffix adds a piston magnet for reed or electronic switches.
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 PSBR10X50SU FAQ
It delivers 29.8 N net push at 0.5 MPa and 45.5 N at 0.7 MPa. Because a return spring counteracts the air pressure, a minimum of 0.2 MPa is required before the rod moves, and the cylinder fails safe to the retracted position on air loss.
It mounts directly via the M4x0.7 thread on the front cover, requiring no separate bracket. The S suffix denotes a built-in piston magnet that works with both reed and electronic solid-state switches for position sensing.
