Airtac PTBR Single Acting Square Head Compact Cylinder PTBR12X10SR
The AirTAC Airtac PTBR Single Acting Square Head Compact Cylinder PTBR12X10SR 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 Ø12mm bore, 10mm stroke; the return spring resets the rod when air is released.

About the Airtac PTBR Single Acting Square Head Compact Cylinder PTBR12X10SR
The AirTAC PTBR12X10SR is a JIS pen-size single-acting pull cylinder with a 12mm bore and 10mm stroke. Air entering the M5x0.8 port retracts the rod, while a spring pushes it back out, providing fail-safe extension on air loss. It yields about 33.1N net pull at 0.5 MPa.
You bolt this directly to a fixture via the front-cover M5x0.8 thread, saving space in tight jigs. The SUS316L stainless barrel resists corrosion, and the -S suffix adds a built-in magnet for reed or electronic switches. A fixed TPU bumper cushions the stroke ends.

|---|---|
| Series | PTBR JIS pen-size front-mount cylinder |
| Bore size | Ø12 mm |
| Rod diameter | Ø5 mm |
| Stroke | 10 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 75 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 (Ø12mm)
| Pressure | Net pull force |
|---|---|
| 0.5 MPa | 33.1 N |
| 0.7 MPa (max) | 51.8 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 PTBR12X10SR Is Used
Hold-Down Clamping
Pulls a small workpiece against a stop during machining. Air retracts the clamp, and loss of pressure safely pushes the rod out to release the part.
Retract-to-Open Gate
Controls a lightweight diverter gate on a conveyor line. The spring holds the gate open by default, while air pulls it closed to divert product.
Wire Tensioning
Maintains steady tension on a filament or wire spool. The cylinder pulls back against the tension, and the fail-safe extend releases the load on air loss.
Is the Airtac PTBR Single Acting Square Head Compact Cylinder PTBR12X10SR the Right Cylinder?
This 12mm bore provides 33.1N net pull at 0.5 MPa and 51.8N at 0.7 MPa. If you need less force, the 10mm bore offers 23.5N at 0.5 MPa; for heavier pulling, the 16mm bore provides 65.0N.
The spring requires a 0.2 MPa minimum pressure to move the rod. The direct front-cover M5x0.8 thread simplifies mounting, and the fail-safe extended position is ideal when rod-out is your safe state. Confirm your bolt engagement and plumbing for the R axial inlet back cover when ordering.
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 ≤ 75 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 PTBR12X10SR FAQ
The net pull force is 33.1N at 0.5 MPa and 51.8N at 0.7 MPa. Because it is single-acting pull, these figures already have the spring force deducted. It requires a minimum pressure of 0.2 MPa to overcome the spring and retract the rod.
It mounts directly via the front-cover M5x0.8 thread, eliminating the need for a separate bracket. The SUS316L stainless barrel provides excellent corrosion resistance for harsh or washdown environments. The -S option includes a magnet for position sensing.
