Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X15R
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X15R 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, 15mm stroke; the return spring resets the rod when air is released.

About the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X15R
The AirTAC PSBR16X15R is a single-acting push pen cylinder that extends via air pressure and retracts via an internal spring. It provides 74.8 N of net push force at 0.5 MPa and 115 N at the 0.7 MPa maximum. The fail-safe spring ensures the rod pulls home on air loss.
This compact actuator features a SUS316L stainless barrel and bolts directly to a fixture via its front-cover M5x0.8 thread. The M5x0.8 air port handles inlet plumbing, while a fixed TPU bumper absorbs end-of-stroke impacts. Plan for a safe working load of about 45 N, which accounts for seal friction and smooth travel.

|---|---|
| Series | PSBR JIS pen-size front-mount cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Stroke | 15 mm |
| Acting type | Single acting, push type (spring return) |
| Front-mount thread | M5×0.8 |
| Port size | M5×0.8 |
|---|---|
| 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 100 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 (M5×0.8); barrel is SUS316L. Forces below are NET spring-deducted values. Confirm against the product label.
Net Push Force (Ø16mm)
| 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.

Where the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X15R Is Used
Part Ejector
Pushes finished components off a machining bed with 74.8 N net force, relying on the spring to retract safely when air pressure drops.
Panel Pusher
Uses the direct M5x0.8 front-mount thread to secure the body tightly against a fixture while indexing light panels down the line.
Clamp Release
Overcomes spring pressure to release a holding clamp, with the fixed TPU bumper softening the impact at the end of the 15mm extension.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X15R the Right Cylinder?
This 16mm bore generates 74.8 N net push at 0.5 MPa. Stepping down, the 12mm bore yields 42.9 N, while stepping up is not possible as 16mm is the largest pen size. The direct front-cover M5x0.8 thread simplifies jig mounting.
The internal spring sets a 0.2 MPa minimum pressure before motion begins. With a 2:1 margin, this model lifts about 3.8 kg vertically. The thin Ø5 mm rod handles coaxial thrust well, but add an external guide for any off-axis loads. Confirm the R axial inlet and 15mm stroke for your build.
Quick checklist
- ✓ Net push force at your working pressure
- ✓ Bolt directly through the front cover (M5×0.8)
- ✓ Only one air line / solenoid needed
- ✓ Fail-safe retract on air loss
- ✓ Magnet (S) for sensors?
- ✓ Stroke ≤ 100 mm (single-acting limit)
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 Match bolt size and engagement to the front thread.
- check Do not add an external return mechanism.
- check Keep the load coaxial; avoid side load on the thin rod.
Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X15R FAQ
The cylinder delivers 74.8 N net push at 0.5 MPa and 115 N at the 0.7 MPa maximum. Because an internal spring returns the rod, a minimum pressure of 0.2 MPa is required before the piston moves.
The SUS316L stainless barrel houses a direct front-cover M5x0.8 mounting thread, allowing straight bolt-on installation without extra brackets. Air enters through a separate M5x0.8 port on the R axial inlet.
