The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X30SU is a single acting, push type (spring return) pen-size mini cylinder with direct front-cover mounting (M5×0.8 thread). A single air port drives the push stroke on a Ø16mm bore, 30mm stroke; the return spring resets the rod when air is released.
The AirTAC PSBR16X30SU is a single-acting push, spring-return pen-size mini cylinder. It supplies 74.8 N of net push at 0.5 MPa and 115 N at the 0.7 MPa maximum. A single M5x0.8 air port extends the rod, while the internal spring ensures a fail-safe retracted state on air loss. The U back cover provides a 90-degree side inlet for flat plumbing.
You mount this cylinder directly via its M5x0.8 front-cover thread, eliminating extra brackets in tight jigs. The SUS316L stainless barrel resists corrosion in damp environments. A fixed TPU bumper decelerates the stroke near the ends. For real-world sizing, plan for a safe working load of about 45 N, which is roughly 60 percent of the 0.5 MPa figure. This equates to lifting about 3.8 kg vertically with a sane 2:1 margin.

The spring holds the rod retracted; applying air pushes the rod out, and removing air lets the spring return it. Front cover carries the mounting thread (M5×0.8); barrel is SUS316L. Forces below are NET spring-deducted values. Confirm against the product label.
| Pressure | Net push force |
|---|---|
| 0.5 MPa | 74.8 N |
| 0.7 MPa (max) | 115.0 N |
These are usable push forces after the return spring is subtracted, 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.

Mounting: direct front-cover thread (M5×0.8). Related PBR-family variants: PBR (double acting), PTBR (single-acting pull).
Uses the 74.8 N push stroke to eject machined parts from a fixture, with the spring ensuring the arm retracts safely when air pressure drops.
Bolts directly via the M5x0.8 front thread to push lightweight panels into a machining cell, saving space in compact assembly lines.
Applies forward thrust to release a secondary clamp, relying on the fail-safe retract design to secure the clamp during an air loss event.
This 16 mm bore yields 74.8 N net push at 0.5 MPa. Stepping down to a 12 mm bore drops the usable push to 42.9 N, while this 16 mm unit maxes out at 115 N at 0.7 MPa. The 30 mm stroke fits well within the 100 mm limit for this bore. The direct M5x0.8 front-mount thread bolts straight to your fixture, and the spring guarantees a fail-safe retracted position.
Confirm the U code for the 90-degree side inlet and the S code for the built-in piston magnet. The magnet works with reed or electronic switches. Because the rod is a slender 5 mm, use an external linear bearing for off-axis loads. The fixed TPU bumper only absorbs the last few millimeters, so meter-out the exhaust if moving heavy tooling at mid speed.
Quick checklist
The net push force is 74.8 N at 0.5 MPa and 115 N at the 0.7 MPa maximum. The internal return spring sets a minimum pressure of 0.2 MPa before the rod can move. On air loss, the spring holds the rod fail-safe retracted.
It mounts directly via an M5x0.8 thread on the front cover, separate from the M5x0.8 air port. The S designation indicates a built-in piston magnet compatible with reed or electronic solid-state switches. The SUS316L stainless barrel suits damp environments.
