AirTAC PSB Series Single-Acting Pen-Size Cylinders
The AirTAC PSB series is a single-acting, spring-return push pen-size mini cylinder spanning 4-16mm bores, built for compact clamping and ejecting where a fail-safe retracted rod is required.
inventory_2208 models availableSeries Overview
The AirTAC PSB series is a single-acting, spring-return push pen-size mini cylinder. Air pressure extends the slim rod through one port, while an internal spring returns it. If air pressure is lost, the spring fails-safe to the retracted position, requiring only one solenoid line to operate.
The range spans five bores: 4, 6, 10, 12 and 16mm. Because it is single-acting, strokes are short and limited by bore size. Net extend force is the air force minus the return-spring force, and a minimum pressure is required before motion begins. Size your specific model from the manufacturer force figure.
Shared design features include a stainless barrel and a fixed TPU bumper that decelerates the piston near stroke end. The series is not a tie-rod, ISO 6432 or ISO 15552 cylinder. Max operating pressure is 0.7 MPa. An -S magnet option is available for position switches. For direct front-mounting and SUS316L material, consider the related PSBR series; for pull action, see PTB; for double-acting, see PB.

Typical Applications
Small Part Ejection
Ejecting small molded or machined parts from tight fixtures. The PSB pen-size footprint fits where standard cylinders cannot, and the spring-return retraction ensures the ejector clears the work area on air loss.
Light Clamping and Gating
Holding lightweight cardboard or thin materials during packaging cycles. The single-acting push design simplifies plumbing to one air line, while the fixed TPU bumper reduces end-of-stroke impact.
Compact Sorting Diverters
Actuating small diverters or gates on high-speed sorting conveyors. The stainless barrel provides durability in space-constrained machinery, and the fail-safe retracted state prevents jams during emergencies.
How to Choose the Right Model
Choose within the PSB series by matching the bore (4-16mm) to your required net extend force, keeping in mind the return-spring deduction and the minimum pressure floor. Select the -S magnet option if you need position confirmation via reed or solid-state switches. Always confirm the specific model figure for exact force output.
Step out of the PSB series to a neighboring AirTAC family if you need double-acting motion (PB series), single-acting pull action (PTB series), or direct front-mounting with SUS316L stainless steel (PSBR series). Before ordering, confirm these 5 points: bore size, required stroke or spec, port/thread, mounting style, and magnet (-S) option.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and available mounting space
- ✓ Port / thread type (PT / NPT / G)
- ✓ Sensor / magnet option (-S)?
- ✓ Side load — consider a guided model
Frequently Asked Questions
The PSB series spans five bores: 4, 6, 10, 12 and 16mm. It is a single-acting push cylinder, so net extend force is the air force minus the return-spring force. A minimum pressure is required before motion begins. Always size from the specific model figure in the datasheet.
PSB is single-acting push (spring-return retracted). PB is double-acting. PTB is single-acting pull. PSBR is also single-acting push but features direct front-mounting and SUS316L stainless steel construction. Choose PSB for standard small clamping and ejecting where a fail-safe retracted rod is required.
The maximum operating pressure is 0.7 MPa. The series uses a fixed TPU bumper for deceleration only. It does not have an adjustable air cushion. The cylinder is not a tie-rod, ISO 6432 or ISO 15552 cylinder.
Yes. The PSB series offers an -S magnet option for use with position switches. If you need to confirm the rod position electrically, specify the -S variant when requesting a quote.
