Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X100R
The AirTAC Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X100R 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, 100mm stroke; the return spring resets the rod when air is released.

About the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X100R
The AirTAC PSBR16X100R is a JIS pen-size single-acting push cylinder with a 16mm bore and 100mm 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, requiring only one solenoid line. It supplies about 74.8 N of net push at 0.5 MPa.
The body bolts directly to a fixture via the front-cover M5x0.8 thread, saving space in tight assemblies. Built with a SUS316L stainless barrel, it handles damp environments. A fixed TPU bumper cushions the stroke ends. Plan for a safe working load of roughly 45 N, which is about 60 percent of the rated figure, to account for seal friction and smooth travel.

| Model | Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X100R |
|---|---|
| Series | PSBR JIS pen-size front-mount cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Stroke | 100 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 PSBR16X100R Is Used
Part Ejection
Uses the spring-return push to eject machined parts from a fixture, guaranteeing the arm pulls back safely if air pressure drops.
Panel Pusher
Bolts directly via the front M5x0.8 thread to push lightweight panels into a nesting spot within compact assembly machinery.
Clamp Release
Lifts or releases a holding clamp vertically, providing up to 3.8 kg of lift with a 2:1 margin at 0.5 MPa.
Is the Airtac PSBR Single Acting Square Head Compact Cylinder PSBR16X100R the Right Cylinder?
This 16mm bore provides 74.8 N net push at 0.5 MPa and 115 N at the 0.7 MPa maximum. If you need less force, the 12mm bore yields 42.9 N at 0.5 MPa. For higher force within the series, you would need a double-acting PBR alternative, as 16mm is the largest pen-size option. The internal return spring sets a 0.2 MPa minimum pressure before motion begins.
The direct front-cover M5x0.8 thread mounts straight to your jig. This specific configuration uses an R axial inlet for in-line plumbing and lacks a sensor magnet. The thin 5mm rod handles coaxial thrust well, but over this 100mm stroke you should add an external guide to prevent side load binding.
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 PSBR16X100R FAQ
The spring is already deducted, yielding 74.8 N net push at 0.5 MPa and 115 N at the 0.7 MPa maximum. Because of the return spring, a minimum pressure of 0.2 MPa is required before the rod extends.
It mounts directly via an M5x0.8 front-cover thread, separate from the M5x0.8 air port. The barrel is SUS316L stainless steel, and this specific model lacks a sensor magnet.
