Airtac PTBR Single Acting Square Head Compact Cylinder PTBR10X60SR
The AirTAC Airtac PTBR Single Acting Square Head Compact Cylinder PTBR10X60SR 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, 60mm stroke; the return spring resets the rod when air is released.

About the Airtac PTBR Single Acting Square Head Compact Cylinder PTBR10X60SR
The AirTAC PTBR10X60SR is a JIS pen-size single-acting pull cylinder that bolts directly via its front-cover M4x0.7 thread. Air entering the M5x0.8 port retracts the rod, while an internal spring pushes it back out, providing 23.5 N of net pull at 0.5 MPa. Because the pull acts on the rod-side annular area, this force is lower than a matching push cylinder. The SUS316L stainless barrel keeps the body slim for tight jigs.
This 60 mm stroke model is fail-safe extended on air loss, making it ideal for tensioning or return-to-home tasks. It includes a built-in magnet for position sensing and a fixed TPU bumper. For smooth operation, plan for a safe working load of about 14 N, which accounts for seal friction. The thin Ø4 mm rod is built for coaxial thrust, so over this long stroke add an external guide to prevent side load damage.

| Rod diameter | Ø4 mm |
| Stroke | 60 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 PTBR10X60SR Is Used
Tension Hold-Down
Pulls a lightweight clamp back against a stop with 23.5 N force, automatically releasing to a safe extended position if air fails.
Retract-to-Open Gate
Uses the direct M4x0.7 front mount to secure a small diverter gate that springs open to a home position when the 0.7 MPa air supply stops.
Light Tensioner
Maintains steady pulling tension on a wire or tape web, leveraging the SUS316L barrel for durability in tight assembly spaces.
Is the Airtac PTBR Single Acting Square Head Compact Cylinder PTBR10X60SR the Right Cylinder?
This 10 mm bore provides 23.5 N net pull at 0.5 MPa (36.7 N at 0.7 MPa max). If you need less force, the Ø8 bore offers 12.4 N; if you need more, the Ø12 bore provides 33.1 N. The direct front-cover M4x0.7 mount simplifies fixture integration, and the fail-safe spring-extend design ensures the rod stays out when air pressure drops.
Confirm your space constraints, as this 60 mm stroke is the maximum for this bore. The R axial inlet keeps plumbing in line. The built-in magnet works with reed or electronic switches, and the M5x0.8 air port requires filtered air.
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 PTBR10X60SR FAQ
It provides 23.5 N net pull at 0.5 MPa and 36.7 N at 0.7 MPa. A minimum pressure of 0.2 MPa is required to overcome the spring and move the rod. If air is lost, the spring pushes the rod out to a fail-safe extended state.
It mounts directly via the front-cover M4x0.7 thread, eliminating brackets. The S suffix indicates a built-in piston magnet compatible with reed or electronic switches. The fixed TPU bumper decelerates the stroke, but at high speeds with real mass, meter-out the exhaust or add an external shock absorber.
