Airtac PTBR Single Acting Square Head Compact Cylinder PTBR16X30SR
The AirTAC Airtac PTBR Single Acting Square Head Compact Cylinder PTBR16X30SR 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, 30mm stroke; the return spring resets the rod when air is released.

About the Airtac PTBR Single Acting Square Head Compact Cylinder PTBR16X30SR
The AirTAC PTBR16X30SR is a JIS pen-size single-acting pull cylinder featuring a direct M5x0.8 front-cover mounting thread. 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 supplies 65 N of net pull at 0.5 MPa and 101.2 N at 0.7 MPa.
Built with a SUS316L stainless barrel and a slim Ø5 mm rod, this unit saves space in tight jigs. The fixed TPU bumper decelerates the stroke at both ends. Because the -S suffix denotes a built-in magnet, you can track position with reed or electronic switches.

|---|---|
| Series | PTBR JIS pen-size front-mount cylinder |
| Bore size | Ø16 mm |
| Rod diameter | Ø5 mm |
| Stroke | 30 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 PTBR16X30SR Is Used
Hold-Down Clamping
Uses spring pressure to hold a workpiece extended, then air pulls the clamp back to release the part for automated machining.
Retract-to-Open Gate
Maintains a gate closed via spring force for fail-safe routing, applying air to pull the gate open when items need to pass.
Web Tensioner
Keeps a tensioning roller extended into a material web, using the single-acting pull to retract and slacken the line for splicing.
Is the Airtac PTBR Single Acting Square Head Compact Cylinder PTBR16X30SR the Right Cylinder?
When sizing this model, compare its 65 N net pull at 0.5 MPa against adjacent bores: the Ø12 version yields 33.1 N, while there is no larger bore in this pen series. The spring requires a minimum 0.2 MPa operating pressure to move the rod. This fail-safe extend behavior is ideal for hold-down or tensioning tasks where rod-out is the safe state.
The direct front-cover M5x0.8 thread bolts straight to your fixture, eliminating separate brackets. Confirm your plumbing uses the R axial inlet back cover, and verify the 30 mm stroke fits your fixture travel. The thin Ø5 mm rod handles coaxial thrust well, but add an external guide for any 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 PTBR16X30SR 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 air pressure to retract the rod. If air loss occurs, the spring pushes the rod out to a fail-safe extended position.
It mounts directly via the M5x0.8 front-cover thread. The -S suffix indicates a built-in piston magnet compatible with reed or electronic switches. The SUS316L stainless barrel provides durability in tight spaces.
