The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR12X60SR 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 Ø12mm bore, 60mm stroke; the return spring resets the rod when air is released.
The AirTAC PSBR12X60SR is a JIS pen-size single-acting push cylinder with a 60mm stroke. Air entering the M5x0.8 port extends the rod, while an internal spring retracts it on air release. This fail-safe design keeps the rod retracted during pressure loss, requiring only one solenoid line. It provides 42.9 N of net push at 0.5 MPa and 65.5 N at 0.7 MPa.
You mount this cylinder directly via its front-cover M5x0.8 thread, saving space in tight jigs. The SUS316L stainless barrel and slim body suit light end-of-arm tooling. A fixed TPU bumper decelerates the rod at stroke ends. Because the return spring sets a minimum pressure of 0.2 MPa, plan for a safe working load of about 26 N (roughly 60% of the 0.5 MPa rating) to account for seal friction. This equates to lifting about 2.2 kg vertically with a 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 | 42.9 N |
| 0.7 MPa (max) | 65.5 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.

| 12 | Bore size in mm. |
| ×60 | Stroke length in mm. |
| S | Built-in magnet for magnetic-switch position sensing (omit = no magnet). |

Mounting: direct front-cover thread (M5×0.8). Related PBR-family variants: PBR (double acting), PTBR (single-acting pull).
Extends to push a light panel into a machining nest, with the internal spring safely pulling the rod back when air drops.
Uses the 42.9 N net push at 0.5 MPa to kick completed parts off a conveyor line before retracting into a compact footprint.
Mounts directly via the front M5x0.8 thread to release a secondary clamp, saving space in dense tooling arrays.
This 12mm bore, 60mm stroke model sits near the single-acting limit of 75mm. Stepping down to a 10mm bore yields 29.8 N net push at 0.5 MPa, while the larger 16mm bore offers 74.8 N. Choose the PSBR12X60SR when your fixture needs moderate push force and fail-safe spring retraction. The direct front-cover M5x0.8 thread bolts straight to your bracket, and the R axial inlet allows inline plumbing.
The built-in magnet (-S) supports reed or electronic switches for position sensing. Remember the thin Ø5 mm rod handles coaxial thrust well but requires an external guide for off-axis loads over this 60mm stroke. Confirm your air line filters to 40 um and verify the M5x0.8 port matches your fittings.
Quick checklist
It delivers 42.9 N of net push at 0.5 MPa and 65.5 N at the 0.7 MPa maximum. Because it is single-acting push with a return spring, it requires a minimum pressure of 0.2 MPa to overcome the spring before the rod moves, and it fails safe to the retracted position on air loss.
It mounts directly via a front-cover M5x0.8 thread, eliminating separate brackets. The -S suffix indicates a built-in piston magnet compatible with AirTAC reed or electronic solid-state switches. The SUS316L stainless barrel provides durability in tight, lightweight jigs.
