Airtac PSB Single Acting Compact Cylinder PSB10X30CB
The AirTAC Airtac PSB Single Acting Compact Cylinder PSB10X30CB is a single acting, push type (spring return) pen-size mini cylinder with a Ø10mm bore and 30mm 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 PSB10X30CB
The AirTAC PSB10X30CB is a JIS pen-size single-acting push cylinder with a 10 mm bore and 30 mm stroke. Air entering the single M5x0.8 port extends the Ø4 mm rod, while an internal spring ensures fail-safe retraction upon air loss. It delivers 29.8 N of net push force at 0.5 MPa, rising to 45.5 N at the 0.7 MPa maximum. The CB double clevis back cover accommodates pivoting loads.
Built with a SUS304 stainless barrel and rod, this slim mini body fits tight jigs and light end-of-arm tooling. A fixed TPU bumper cushions the stroke ends. Plan for a safe working load of about 18 N, which is roughly 60 percent of the 0.5 MPa rating, to account for seal friction. The thin rod handles coaxial thrust, so add an external guide for any off-axis loads.
Airtac PSB Single Acting Compact Cylinder PSB10X30CB Technical Specifications
| Model | Airtac PSB Single Acting Compact Cylinder PSB10X30CB |
|---|---|
| Series | PSB JIS pen-size mini cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Stroke | 30 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 (Ø10mm)
| Pressure | Net push force |
|---|---|
| 0.5 MPa | 29.8 N |
| 0.7 MPa (max) | 45.5 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 PSB10X30CB Is Used
Pivoting Part Ejector
Uses the CB double clevis to swing and push completed plastic parts off a conveyor line, relying on the spring to safely retract the pin during air loss.
Carton Flap Folder
Deploys the rod to fold minor flaps on a packaging machine, with the fail-safe return preventing jams if the air supply drops unexpectedly.
Clamp Release Gate
Acts as a pusher to open a lightweight sorting gate on an assembly line, using the single air line to simplify tubing and reduce valving costs.
Is the Airtac PSB Single Acting Compact Cylinder PSB10X30CB the Right Cylinder?
This 10 mm bore provides 29.8 N net push at 0.5 MPa. If your task needs less force, the Ø6 bore offers 10.6 N; for heavier pushing, the Ø12 bore yields 42.9 N. The internal spring demands a minimum 0.2 MPa operating pressure before motion begins. When ordering, confirm the 30 mm stroke, the CB double clevis inlet, and whether you require the S magnet option for switch sensing.
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 PSB10X30CB FAQ
The net push force is 29.8 N at 0.5 MPa and 45.5 N at the 0.7 MPa maximum. Because the internal return spring opposes the air stroke, a minimum operating pressure of 0.2 MPa is required before the rod moves. The spring ensures the rod fails safe in the retracted position.
It uses a fixed TPU bumper at each end to decelerate the stroke over the last few millimeters. This bumper is not adjustable, so at higher speeds with real tooling mass you should meter-out the exhaust or add an external shock absorber. The CB double clevis back cover allows the cylinder to pivot on its mounting point.
