Airtac PSB Single Acting Compact Cylinder PSB6X35SR
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB6X35SR is a single acting, push type (spring return) pen-size mini cylinder with a Ø6mm bore and 35mm 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 PSB6X35SR
The AirTAC PSB6X35SR is a JIS pen-size single-acting push cylinder that extends via one M5x0.8 air port and retracts via a built-in spring. It provides 10.6 N of net push at 0.5 MPa, with a slim SUS304 stainless body suited for tight jigs. Because the spring constantly opposes the air stroke, the rod remains safely retracted if air pressure drops.
This model includes a built-in piston magnet for position sensing and an axial R back cover for in-line plumbing. A fixed TPU bumper cushions the stroke ends. For reliable operation, plan for a safe working load of roughly 6 N, which accounts for seal friction at 60 percent of the rated force.
Airtac PSB Single Acting Compact Cylinder PSB6X35SR Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB6X35SR |
|---|---|
| Series | PSB JIS pen-size mini cylinder |
| Bore size | Ø6 mm |
| Rod diameter | Ø3 mm |
| Stroke | 35 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 PSB6X35SR Is Used
Small Part Ejector
Pushes lightweight plastic components out of a machining fixture, with the spring safely pulling the rod back when air is cut.
Package Diverter Gate
Acts as a compact routing flap on a packaging line, using the single air line to extend and block flow momentarily.
Lab Sample Marker
Depresses a stamping head onto test tubes in a damp environment, relying on the stainless build and fail-safe retract.
Is the Airtac PSB Single Acting Compact Cylinder PSB6X35SR the Right Cylinder?
This 6 mm bore generates 10.6 N net push at 0.5 MPa, sitting between the smaller 4 mm bore (4.1 N) and the larger 10 mm bore (29.8 N). The internal return spring demands a minimum operating pressure of 0.2 MPa before the rod begins moving. When ordering, verify the 35 mm stroke, the S magnet option, the R axial inlet, and your required mounting bracket.
The slender Ø3 mm piston rod handles coaxial thrust well but requires an external linear bearing if subjected to off-axis loads over this 35 mm stroke. With a 2:1 safety margin, expect to lift about 0.5 kg vertically.
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 PSB6X35SR FAQ
It delivers 10.6 N net push at 0.5 MPa and 16.3 N at 0.7 MPa maximum. Because an internal spring returns the rod, a minimum pressure of 0.2 MPa is required to overcome the spring before extension begins.
It uses a fixed TPU bumper at each end to decelerate the last few millimeters of travel; at higher speeds with real tooling mass, meter-out the exhaust or add an external shock absorber. The S suffix denotes a built-in magnet compatible with reed or electronic switches.
