Airtac PTBR Single Acting Square Head Compact Cylinder PTBR16X10SR
The AirTAC Airtac PTBR Single Acting Square Head Compact Cylinder PTBR16X10SR is a single acting, pull type (spring extend) pen-size mini cylinder with direct front-cover mounting (M5×0.8 thread). A single air port drives the pull stroke on a Ø16mm bore, 10mm stroke; the return spring resets the rod when air is released.

About the Airtac PTBR Single Acting Square Head Compact Cylinder PTBR16X10SR
The AirTAC PTBR16X10SR is a JIS pen-size single-acting pull cylinder with a 16mm bore and 10mm stroke. Air entering the M5x0.8 port retracts the rod, while a spring extends it out, ensuring a fail-safe extended state on air loss. It provides 65 N of net pull at 0.5 MPa and 101.2 N at 0.7 MPa.
You mount it directly via the front-cover M5x0.8 thread into your fixture. The SUS316L stainless barrel keeps the body slim. Because the pull acts on the rod-side area, this output is lower than a matching push cylinder. The built-in magnet (-S) supports reed or electronic switches.

|---|---|
| Series | PTBR JIS pen-size front-mount cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Stroke | 10 mm |
| Acting type | Single acting, pull type (spring extend) |
| 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 (pull by air) |
| Max standard stroke | Up to 100 mm |
The spring holds the rod extended; applying air retracts it, and removing air lets the spring push the rod back out. 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 Pull Force (Ø16mm)
| Pressure | Net pull force |
|---|---|
| 0.5 MPa | 65.0 N |
| 0.7 MPa (max) | 101.2 N |
These are usable pull 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 PTBR Single Acting Square Head Compact Cylinder PTBR16X10SR Is Used
Fail-Safe Hold-Down Clamp
Holds a workpiece extended during normal operation and releases tension automatically if air pressure drops, keeping the clamp safely open.
Retract-to-Open Gate
Uses the 65 N pull to draw a lightweight diverter gate closed against a spring, defaulting to an open path when the air supply stops.
Spring-Return Tensioner
Maintains steady belt tension by pulling back on a mount block, with the internal spring pushing the rod out to slacken the line on shutdown.
Is the Airtac PTBR Single Acting Square Head Compact Cylinder PTBR16X10SR the Right Cylinder?
This 16mm bore yields 65 N net pull at 0.5 MPa. If you need less force, the 12mm bore offers 33.1 N. If you need more, you are at the top of this pen-size range. Plan for a safe working load of about 39 N, which is roughly 60 percent of the rated figure, to account for seal friction.
A spring requires a minimum 0.2 MPa pressure before motion begins. The direct front-cover M5x0.8 thread bolts straight to your jig, and the separate M5x0.8 air port handles plumbing. Confirm you have the R axial inlet back cover and the -S magnet for your sensing needs.
Quick checklist
- ✓ Net pull force at your working pressure
- ✓ Bolt directly through the front cover (M5×0.8)
- ✓ Only one air line / solenoid needed
- ✓ Fail-safe extend 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 PTBR Single Acting Square Head Compact Cylinder PTBR16X10SR FAQ
It provides 65 N of net pull at 0.5 MPa and 101.2 N at 0.7 MPa. Because it is spring-extended, a minimum pressure of 0.2 MPa is required to overcome the spring and retract the rod. The rod fails safe to the extended position on air loss.
It bolts directly to your fixture via the front-cover M5x0.8 thread. The -S suffix indicates a built-in piston magnet compatible with reed or electronic switches. The SUS316L stainless barrel houses the M5x0.8 air port on the R axial back cover.
