Airtac PTBR Single Acting Square Head Compact Cylinder PTBR16X75R
The AirTAC Airtac PTBR Single Acting Square Head Compact Cylinder PTBR16X75R 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, 75mm stroke; the return spring resets the rod when air is released.

About the Airtac PTBR Single Acting Square Head Compact Cylinder PTBR16X75R
The AirTAC PTBR16X75R is a JIS pen-size single-acting pull cylinder with a 16 mm bore and 75 mm stroke. Air entering the M5x0.8 port retracts the rod, while an internal spring pushes it back out, ensuring a fail-safe extended state upon air loss. It provides 65 N of net pull at 0.5 MPa and 101.2 N at the 0.7 MPa maximum, with the spring force already deducted.
You bolt this actuator directly to a fixture via its M5x0.8 front-cover thread, eliminating extra brackets. The SUS316L stainless barrel shrinks the footprint for light end-of-arm tooling. Because the fixed TPU bumper only decelerates the final few millimeters, metering out the exhaust is recommended when moving real tooling mass at higher speeds.

| Stroke | 75 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 PTBR16X75R Is Used
Vertical Hold Jig
Use the spring-extend action to lift a 3.3 kg fixture safely. The direct front mount bolts right to the frame, keeping the assembly compact.
Tensioning Station
Apply steady pulling force on a belt or wire. Releasing air lets the spring push the rod out, maintaining tension during an emergency stop.
Retract-to-Open Gate
Pull a small access gate open with 65 N at 0.5 MPa. Air loss automatically extends the rod to close the gate for secure fail-safe operation.
Is the Airtac PTBR Single Acting Square Head Compact Cylinder PTBR16X75R the Right Cylinder?
This 16 mm bore yields 65 N net pull at 0.5 MPa. Stepping down to a 12 mm bore drops the usable pull to 33.1 N, while the 16 mm remains the largest standard option in this pen series. Plan for a safe working load of roughly 39 N, which is about 60 percent of the rated figure, to account for seal friction and smooth travel.
The direct front-cover thread and fail-safe extend behavior suit tensioning and hold-down duties. Confirm your plumbing uses the R axial back cover inlet, and note this specific model ships without a sensor magnet.
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 PTBR16X75R FAQ
It delivers 65 N net pull at 0.5 MPa and 101.2 N at 0.7 MPa maximum. A minimum pressure of 0.2 MPa is required to overcome the spring and move the rod. The spring holds the rod extended if air pressure drops.
It mounts directly via the M5x0.8 front-cover thread. Air plumbing enters through the R axial back cover inlet. The SUS316L stainless barrel provides durability in tight spaces.
