Airtac PSB Single Acting Compact Cylinder PSB6X15SR
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB6X15SR is a single acting, push type (spring return) pen-size mini cylinder with a Ø6mm bore and 15mm stroke. A single air port drives the push stroke; the built-in return spring resets the rod when air is released, so only one solenoid line is needed.

About the Airtac PSB Single Acting Compact Cylinder PSB6X15SR
The AirTAC PSB6X15SR is a JIS pen-size single-acting push cylinder with a 6 mm bore and 15 mm stroke. Air entering the single M5x0.8 port extends the Ø3 mm rod, while an internal spring ensures fail-safe retraction upon air loss. Because the spring counteracts the air stroke, it provides 10.6 N of net usable push force at 0.5 MPa, requiring a minimum 0.2 MPa operating pressure to overcome the spring. The -S suffix indicates a built-in piston magnet for position detection.
Built with a SUS304 stainless steel barrel and rod, this slim mini body fits tight jigs and light end-of-arm tooling. It uses a fixed TPU bumper at each end to decelerate motion over the final few millimeters. For real-world sizing, plan for a safe working load of about 6 N (roughly 60 percent of the 0.5 MPa rating) to account for seal friction and smooth travel.
Airtac PSB Single Acting Compact Cylinder PSB6X15SR Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB6X15SR |
|---|---|
| Series | PSB JIS pen-size mini cylinder |
| Bore size | Ø6 mm |
| Rod diameter | Ø3 mm |
| Stroke | 15 mm |
| Acting type | Single acting, push type (spring return) |
| Port size | M5×0.8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| 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. Forces below are the NET spring-deducted values from the AirTAC thrust table. Confirm against the product label before installation.
Net Push Force (Ø6mm)
| Pressure | Net push force |
|---|---|
| 0.5 MPa | 10.6 N |
| 0.7 MPa (max) | 16.3 N |
These are the usable push forces after the return spring is subtracted, taken directly 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 PSB Single Acting Compact Cylinder PSB6X15SR Is Used
Small Part Ejection
Pushes lightweight plastic components out of an inspection fixture on a packaging line, using the spring to safely retract the pin when air is removed.
Sorting Diverter
Acts as a compact gate actuator on a narrow conveyor, briefly extending to deflect small hardware items into a secondary chute before returning home.
Lab Sample Clamp
Holds a delicate test vial in place on a testing rig with a soft 6 N working load, releasing it instantly if the compressed air supply drops.
Is the Airtac PSB Single Acting Compact Cylinder PSB6X15SR the Right Cylinder?
When sizing this 6 mm bore model, consider the neighboring options. Stepping down is not available below Ø6, but stepping up to the Ø10 bore raises the net push to 29.8 N at 0.5 MPa for heavier tasks. The internal return spring sets a 0.2 MPa minimum pressure before motion begins and holds the rod safely retracted without live air. Confirm your ordering essentials: 6 mm bore, 15 mm stroke, built-in magnet (-S), and the R axial back cover for in-line plumbing.
Quick checklist
- ✓ Net push force at your working pressure
- ✓ Only one air line / solenoid needed
- ✓ Fail-safe retract on air loss
- ✓ Magnet (S) for sensors?
- ✓ Stroke ≤ 60 mm (single-acting limit)
- ✓ Keep the load coaxial — avoid side load
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 Do not add an external return mechanism.
- check Keep the load coaxial; avoid side load on the thin rod.
- check Do not dismantle the front or back cover.
Airtac PSB Single Acting Compact Cylinder PSB6X15SR FAQ
It delivers 10.6 N of net push force at 0.5 MPa and 16.3 N at the 0.7 MPa maximum. Because it is spring-return, a minimum of 0.2 MPa is required to overcome the spring and extend the rod. The spring ensures the rod retracts to a safe home position on air loss.
The -S suffix provides a built-in piston magnet compatible with AirTAC reed or electronic switches for end-of-stroke detection. Deceleration is handled by a fixed TPU bumper at each end; it is not adjustable, so at high speeds with real tooling mass you should meter-out the exhaust or add an external shock absorber.
