The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR10X40SR is a single acting, push type (spring return) pen-size mini cylinder with direct front-cover mounting (M4×0.7 thread). A single air port drives the push stroke on a Ø10mm bore, 40mm stroke; the return spring resets the rod when air is released.
The AirTAC PSBR10X40SR is a JIS pen-size single-acting push cylinder with a 10 mm bore and 40 mm stroke. Air entering the M5x0.8 port extends the rod, while an internal spring retracts it automatically. This fail-safe design ensures the rod returns home on air loss. It supplies 29.8 N of net push at 0.5 MPa and 45.5 N at 0.7 MPa.
The body features a SUS316L stainless barrel and a slim profile for tight jigs. You mount it directly via the front-cover M4x0.7 thread, eliminating extra brackets. A fixed TPU bumper cushions the stroke ends. The built-in -S magnet supports reed or electronic switches for position sensing. Plan for a safe working load of about 18 N, which is roughly 60 percent of the 0.5 MPa rating.

| 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. Front cover carries the mounting thread (M4×0.7); barrel is SUS316L. Forces below are NET spring-deducted values. Confirm against the product label.
| Pressure | Net push force |
|---|---|
| 0.5 MPa | 29.8 N |
| 0.7 MPa (max) | 45.5 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 (M4×0.7). Related PBR-family variants: PBR (double acting), PTBR (single-acting pull).
Pushes finished parts off a conveyor line with 29.8 N net force at 0.5 MPa, retracting safely when air stops.
Uses the direct M4x0.7 front-mount thread to secure inside a tight jig, extending 40 mm to index panels.
Overcomes spring tension to open a holding clamp, relying on the fail-safe retract to reset the mechanism.
For this 10 mm bore, the 29.8 N net push at 0.5 MPa handles light ejecting tasks. If you need less force, the 8 mm bore version offers 18.7 N. For heavier jobs, the 12 mm bore provides 42.9 N. This PSBR10X40SR uses a 40 mm stroke, safely under the 60 mm single-acting limit.
The direct M4x0.7 front-cover thread bolts straight to your fixture. The internal spring sets a 0.2 MPa minimum pressure before motion begins. The R axial inlet keeps plumbing in-line. Remember the thin 4 mm rod is for coaxial thrust; add an external guide for off-axis loads.
Quick checklist
The net push force is 29.8 N at 0.5 MPa and 45.5 N at the 0.7 MPa maximum. The internal return spring requires a minimum of 0.2 MPa before the rod extends, and the cylinder fails safely retracted on air loss.
It mounts directly via the front-cover M4x0.7 thread. The SUS316L stainless barrel resists damp environments. The included -S magnet works with AirTAC reed or electronic switches for position confirmation.
