Airtac PTBR Single Acting Square Head Compact Cylinder PTBR16X60R
The AirTAC Airtac PTBR Single Acting Square Head Compact Cylinder PTBR16X60R 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, 60mm stroke; the return spring resets the rod when air is released.

About the Airtac PTBR Single Acting Square Head Compact Cylinder PTBR16X60R
The AirTAC PTBR16X60R is a single-acting pull pen-size mini cylinder with a 16mm bore and 60mm stroke. Air entering the M5x0.8 port retracts the rod, while an internal spring pushes it back out, ensuring fail-safe extension on air loss. It delivers 65N of net pull at 0.5MPa and 101.2N at the 0.7MPa maximum.
You bolt this directly to a fixture via the M5x0.8 front-cover thread, while the R back cover provides a tidy axial inline air inlet. The SUS316L stainless barrel resists corrosion in tight jigs. For practical sizing, plan for a safe working load of about 39N (roughly 60% of the 0.5MPa figure) to account for seal friction. The fixed TPU bumper decelerates the final few millimeters of travel.

|---|---|
| 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 PTBR16X60R Is Used
Hold-Down Clamping
Pulls a clamp down onto a workpiece under air pressure; the spring automatically releases the clamp upward if the air supply drops.
Retract-to-Open Gate
Uses the 65N pull to draw a diverter gate closed for routing parts, then vents air so the spring pushes the gate open for a safe default state.
Web Tensioner
Maintains tension on a filament or web by pulling a guide pulley back against a stop, returning to a relaxed position upon air loss.
Is the Airtac PTBR Single Acting Square Head Compact Cylinder PTBR16X60R the Right Cylinder?
This 16mm bore yields 65N net pull at 0.5MPa. Stepping down to a 12mm bore drops the usable pull to 33.1N, while 16mm is the largest available pen-size option in this series, offering the highest 101.2N at 0.7MPa. Choose this model when you need maximum pull force in a compact footprint.
The spring requires a minimum 0.2MPa to function. Because the rod is a slender 5mm diameter, add an external guide for off-axis loads over this 60mm stroke. The R suffix specifies the axial inlet back cover, and this configuration ships without a 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 PTBR16X60R FAQ
It provides 65N net pull at 0.5MPa and 101.2N at 0.7MPa maximum. Because it is a single-acting pull cylinder, a minimum 0.2MPa is required to overcome the spring and retract the rod; removing air leaves the rod fail-safe extended.
It mounts directly via the M5x0.8 thread on the front cover, eliminating separate brackets. The R back cover features an axial inline air inlet, and the body uses a SUS316L stainless barrel. This specific SKU does not include a sensor magnet.
