Airtac PSB Single Acting Compact Cylinder PSB6X15R
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB6X15R 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 PSB6X15R
The AirTAC PSB6X15R is a JIS pen-size single-acting push cylinder that extends via one M5x0.8 air port and retracts automatically via an internal spring. It yields 10.6 N of net push at 0.5 MPa and 16.3 N at 0.7 MPa, utilizing a slim SUS304 stainless body and a Ø3 mm rod with an M5x0.8 end thread. This fail-safe design ensures the rod pulls home whenever air pressure drops.
Because the return mechanism constantly opposes the air stroke, a minimum of 0.2 MPa is required before motion begins. The R suffix denotes an axial inlet for inline plumbing, simplifying tubing in dense layouts. A fixed TPU bumper cushions the stroke ends, and since no magnet is installed, positioning requires external mechanical stops.
Airtac PSB Single Acting Compact Cylinder PSB6X15R Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB6X15R |
|---|---|
| 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 PSB6X15R Is Used
Small Part Ejector
Pushes lightweight stamped electronics from a die on an assembly line, relying on the spring to safely retract the pin when air is cut.
Package Diverter Gate
Acts as a compact routing flap actuator on a packaging conveyor, using the single air line to extend and block flow before springing back.
Lab Test Clamp
Secures delicate glass vials during a filling process with a soft 6 N working force, releasing instantly upon pneumatic exhaust.
Is the Airtac PSB Single Acting Compact Cylinder PSB6X15R the Right Cylinder?
Selecting this 6 mm bore over the smaller Ø4 grants higher thrust, while stepping up to a Ø10 bore provides 29.8 N at 0.5 MPa for heavier tooling. At 0.5 MPa, plan for a safe working load of roughly 6 N, which translates to lifting about 0.5 kg vertically with a sane 2:1 margin. The Ø3 mm rod is built for coaxial thrust, so add an external linear bearing if side loads are present.
Confirm your ordering essentials: 6 mm bore, 15 mm stroke, no magnet, R axial back cover, and standard mounting. Remember the internal spring sets the 0.2 MPa minimum operating pressure, and max pressure is 0.7 MPa.
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 PSB6X15R FAQ
The net usable push force is 10.6 N at 0.5 MPa and 16.3 N at 0.7 MPa. Because the internal spring opposes extension, a minimum operating pressure of 0.2 MPa is required to move the rod.
It uses a fixed TPU bumper at the stroke ends to decelerate motion over the last few millimeters. The spring automatically retracts the rod on air loss for a fail-safe home position, but it is not a locking brake for external loads.
