Airtac PTBR Single Acting Square Head Compact Cylinder PTBR10X30SR
The AirTAC Airtac PTBR Single Acting Square Head Compact Cylinder PTBR10X30SR is a single acting, pull type (spring extend) pen-size mini cylinder with direct front-cover mounting (M4×0.7 thread). A single air port drives the pull stroke on a Ø10mm bore, 30mm stroke; the return spring resets the rod when air is released.

About the Airtac PTBR Single Acting Square Head Compact Cylinder PTBR10X30SR
The AirTAC PTBR10X30SR is a JIS pen-size single-acting pull cylinder with a 10mm bore and 30mm stroke. Spring pressure holds the rod extended by default, while supplying air to the M5x0.8 port retracts it. This fail-safe extended behavior ensures your tooling returns to a safe home position if air pressure drops. It delivers 23.5N of net pull at 0.5 MPa.
You mount this actuator directly via its front-cover M4x0.7 thread, eliminating extra brackets to save space on tight jigs. The SUS316L stainless barrel resists corrosion, and a fixed TPU bumper cushions the stroke ends. The -S suffix adds a piston magnet for position sensing.

|---|---|
| Series | PTBR JIS pen-size front-mount cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Stroke | 30 mm |
| Acting type | Single acting, pull type (spring extend) |
| Front-mount thread | M4×0.7 |
| 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 60 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 (M4×0.7); barrel is SUS316L. Forces below are NET spring-deducted values. Confirm against the product label.
Net Pull Force (Ø10mm)
| Pressure | Net pull force |
|---|---|
| 0.5 MPa | 23.5 N |
| 0.7 MPa (max) | 36.7 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 PTBR10X30SR Is Used
Hold-Down Clamping
Uses spring pressure to keep a workpiece clamped securely. Air retracts the rod to release the part, ensuring the clamp stays engaged during an air loss event.
Retract-to-Open Gate
Spring force holds a diverter gate closed across the belt. Pneumatic pressure pulls the gate back to open the lane, automatically closing if the air supply stops.
Tensioner Mechanism
Maintains steady tension on a film or wire strand. The spring-extended rod pulls back automatically, providing consistent tension without continuous air consumption.
Is the Airtac PTBR Single Acting Square Head Compact Cylinder PTBR10X30SR the Right Cylinder?
When sizing this 10mm bore, note it yields 23.5N net pull at 0.5 MPa and 36.7N at the 0.7 MPa maximum. If your task needs less force, the 8mm version provides 12.4N at 0.5 MPa. For heavier pulling, step up to the 12mm bore offering 33.1N. Remember the internal spring requires a minimum 0.2 MPa pressure to overcome before motion begins.
This PTBR10X30SR variant includes the -S magnet for reed or electronic switches and the -R axial inlet for inline plumbing. The direct M4x0.7 front-mount thread bolts straight to your fixture. Because the rod is a slender 4mm diameter, use an external guide for any off-axis loads to prevent bending.
Quick checklist
- ✓ Net pull force at your working pressure
- ✓ Bolt directly through the front cover (M4×0.7)
- ✓ Only one air line / solenoid needed
- ✓ Fail-safe extend on air loss
- ✓ Magnet (S) for sensors?
- ✓ Stroke ≤ 60 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 PTBR10X30SR FAQ
It provides 23.5N net pull at 0.5 MPa and 36.7N at 0.7 MPa. A minimum of 0.2 MPa is required to overcome the spring and retract the rod. If air is lost, the spring pushes the rod back out to a fail-safe extended position.
It mounts directly via the front-cover M4x0.7 thread. The -S suffix indicates a built-in piston magnet compatible with reed or electronic switches. It features a SUS316L stainless barrel and an R axial air inlet for inline plumbing.
