Airtac PTBR Single Acting Square Head Compact Cylinder PTBR10X60R
The AirTAC Airtac PTBR Single Acting Square Head Compact Cylinder PTBR10X60R 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 PTBR10X60R
The AirTAC PTBR10X60R is a JIS pen-size single-acting pull cylinder with a 60mm stroke. Air entering the M5x0.8 port retracts the rod, while an internal spring pushes it back out. This provides 23.5N of net pull at 0.5 MPa. Because the spring holds the rod extended, the cylinder fails safe on air loss.
It bolts directly to a fixture via the front-cover M4x0.7 thread. The SUS316L stainless barrel and slim body save space in tight jigs. A fixed TPU bumper cushions the stroke ends. Plan for a safe working load of about 14N, which is roughly 60% of the 0.5 MPa rating.

|---|---|
| Series | PTBR JIS pen-size front-mount cylinder |
| Bore size | Ø10 mm |
| 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 PTBR10X60R Is Used
Hold-Down Clamp
Pulls a clamp back to release a part, with the spring automatically pushing the clamp out to secure the part if air pressure drops.
Retract-to-Open Gate
Uses the 23.5N pull to retract a diverter gate on a conveyor, letting the spring extend it closed as a default safety position.
Wire Tensioner
Maintains steady tension on a filament or wire line, pulling back under air and extending smoothly when air is released.
Is the Airtac PTBR Single Acting Square Head Compact Cylinder PTBR10X60R the Right Cylinder?
This 10mm bore at its 60mm maximum single-acting stroke provides 23.5N net pull at 0.5 MPa. If you need less force, the 8mm bore offers 12.4N. If you need more, the 12mm bore yields 33.1N. All three require the 0.2 MPa minimum spring pressure to move.
The direct M4x0.7 front-cover mount eliminates separate brackets. Remember the thin 4mm rod is for coaxial thrust only; over this 60mm stroke, add an external guide for any off-axis loads. This PTBR10X60R variant includes the R axial inlet back cover but no sensor magnet.
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 PTBR10X60R FAQ
It provides 23.5N net pull at 0.5 MPa and 36.7N at the 0.7 MPa maximum. It requires at least 0.2 MPa to overcome the spring and move the rod. The spring holds the rod extended on air loss.
It mounts directly via the front-cover M4x0.7 thread. The R back cover provides an axial M5x0.8 air inlet for in-line plumbing. The SUS316L barrel resists corrosion in tight jigs.
