Airtac PTBR Single Acting Square Head Compact Cylinder PTBR16X100SR
The AirTAC Airtac PTBR Single Acting Square Head Compact Cylinder PTBR16X100SR 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, 100mm stroke; the return spring resets the rod when air is released.

About the Airtac PTBR Single Acting Square Head Compact Cylinder PTBR16X100SR
The AirTAC PTBR16X100SR is a single-acting pull-type pen cylinder with a 16mm bore and 100mm stroke. A built-in spring holds the rod extended, while supplying air to the M5x0.8 port retracts it. It delivers 65 N of net pull at 0.5 MPa, acting on the smaller rod-side area. The direct M5x0.8 front-cover thread mounts straight to your fixture.
Fail-safe extended on air loss, it uses a SUS316L stainless barrel and a fixed TPU bumper. The S suffix adds a piston magnet for reed or electronic switches. Plan for a safe working load of about 39 N, roughly 60% of the rated figure, to account for seal friction.

| Series | PTBR JIS pen-size front-mount cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Stroke | 100 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 PTBR16X100SR Is Used
Tensioning Jig
Pulls a part taut with 65 N net force; the spring automatically returns the rod out if air pressure drops.
Retract-to-Open Gate
Air retracts the 100mm stroke to open a small access gate; removing air springs it safely closed.
Hold-Down Clamp
Bolts via the front M5x0.8 thread to pull a cover down; fail-safe extension lifts the clamp on air loss.
Is the Airtac PTBR Single Acting Square Head Compact Cylinder PTBR16X100SR the Right Cylinder?
This 16mm bore provides 65 N net pull at 0.5 MPa and 101.2 N at 0.7 MPa. Stepping down to a 12mm bore yields 33.1 N, while this 16mm unit is the largest pen-size option. The spring requires a 0.2 MPa minimum pressure to move. For vertical lifts, expect to hold or pull about 3.3 kg with a sane 2:1 safety margin.
The direct front-cover M5x0.8 thread simplifies mounting, and the R axial inlet keeps plumbing in line. The 100mm stroke is the maximum for this bore. Because the 5mm rod is slender over long strokes, add an external guide for off-axis loads.
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 PTBR16X100SR FAQ
It provides 65 N net pull at 0.5 MPa and 101.2 N at 0.7 MPa. The internal spring requires a minimum 0.2 MPa to retract the rod, and the cylinder fails safe to the extended position on air loss.
It mounts directly via the M5x0.8 front-cover thread. The SUS316L stainless barrel resists corrosion, and the S suffix indicates a built-in magnet compatible with reed or electronic switches.
