Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X80SR
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X80SR 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, 80mm stroke; the return spring resets the rod when air is released.

About the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X80SR
The AirTAC PSBR16X80SR is a single-acting push pen cylinder with an 80mm stroke. Air entering the M5x0.8 port extends the rod, while an internal spring ensures fail-safe retraction on air loss. It supplies 74.8N of net push at 0.5MPa, reaching 115N at the 0.7MPa maximum. The return spring is already deducted from these figures.
This model features a SUS316L stainless barrel and a slim mini body that bolts directly to a fixture via the front-cover M5x0.8 thread. A built-in magnet (-S) enables position sensing with reed or electronic switches. The fixed TPU bumper decelerates the stroke end, but with an 80mm travel and real tooling mass, you should meter-out the exhaust or add an external shock absorber.
Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X80SR Technical Specifications
| Model | Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X80SR |
|---|---|
| Series | PSBR JIS pen-size front-mount cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Stroke | 80 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 PSBR16X80SR Is Used
Part Ejector
Pushes machined parts off a conveyor line. The spring retract saves air, using one solenoid line to extend and automatically returning home when air cuts out.
Panel Pusher
Indexes lightweight electronic panels into a testing jig. The direct front-cover thread mounts flush to the machine frame, saving space in tight assemblies.
Clamp Release
Overrides a mechanical latch to release clamped stock. The fail-safe spring retract ensures the clamp locks securely back into place if pneumatic pressure drops.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X80SR the Right Cylinder?
At 0.5MPa this 16mm bore provides 74.8N net push. Stepping down, a 12mm bore yields 42.9N. For higher force, this is the largest pen-size option at 115N on the 0.7MPa max. Plan for a safe working load of about 45N, which is roughly 60% of the 0.5MPa rating to account for seal friction. This equates to lifting about 3.8kg vertically with a 2:1 margin.
The direct M5x0.8 front-mount thread simplifies jig integration without extra brackets. The internal spring sets a 0.2MPa minimum pressure before motion begins and holds the rod retracted safely during air loss. Note the R axial inlet configuration and the 5mm rod diameter when ordering.
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 PSBR16X80SR FAQ
The net push force is 74.8N at 0.5MPa and 115N at the 0.7MPa maximum. Because it is single-acting push with a return spring, it requires a minimum of 0.2MPa to overcome the spring and extend the rod.
It mounts directly via an M5x0.8 thread on the front cover, eliminating separate brackets. The -S suffix indicates a built-in piston magnet compatible with reed or electronic switches for end-of-stroke detection.
