Airtac PTBR Single Acting Square Head Compact Cylinder PTBR8X10R
The AirTAC Airtac PTBR Single Acting Square Head Compact Cylinder PTBR8X10R 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 Ø8mm bore, 10mm stroke; the return spring resets the rod when air is released.

About the Airtac PTBR Single Acting Square Head Compact Cylinder PTBR8X10R
The AirTAC PTBR8X10R is a JIS pen-size single-acting pull cylinder. Air entering the M5x0.8 port retracts the rod, while an internal spring pushes it back out. This provides a fail-safe extended state on air loss, ideal for tensioning or hold-down tasks. It delivers 12.4 N of net pull at 0.5 MPa.
You bolt this actuator directly to a fixture via its M4x0.7 front-cover thread, saving space without extra brackets. The SUS316L stainless barrel resists corrosion in tight jigs. A fixed TPU bumper cushions the stroke ends. For smooth travel, plan a safe working load of about 7 N, which is roughly 60 percent of the rated force.

| Rod diameter | Ø4 mm |
| Stroke | 10 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 (Ø8mm)
| Pressure | Net pull force |
|---|---|
| 0.5 MPa | 12.4 N |
| 0.7 MPa (max) | 19.9 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 PTBR8X10R Is Used
Hold-Down Clamp
Uses spring pressure to keep a part extended and clamped, retracting only when air is applied to release the workpiece.
Retract-to-Open Gate
Holds a diverting gate closed by default and pulls it open on signal, returning to the closed position if air pressure drops.
Wire Tensioner
Maintains steady pulling tension on a filament or wire spool, backing off pneumatically when the tension needs relaxing.
Is the Airtac PTBR Single Acting Square Head Compact Cylinder PTBR8X10R the Right Cylinder?
Select this 8 mm bore, 10 mm stroke model when you need 12.4 N of net pull at 0.5 MPa or 19.9 N at the 0.7 MPa maximum. If your task requires less force, stepping down to a 6 mm bore yields 7.1 N at 0.5 MPa. For heavier pulling, stepping up to a 10 mm bore provides 23.5 N.
The spring sets a 0.2 MPa minimum pressure before motion begins. The direct front-cover mount simplifies installation, and the R axial back cover keeps plumbing in line. The thin 4 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 (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 PTBR8X10R FAQ
It provides 12.4 N of net pull at 0.5 MPa and 19.9 N at 0.7 MPa. Because it is single-acting pull, a minimum of 0.2 MPa is required to overcome the spring and move the rod. The spring ensures the rod stays fail-safe extended on air loss.
It mounts directly via the M4x0.7 thread on the front cover, eliminating brackets. The R back cover features an axial M5x0.8 air inlet for in-line plumbing. The SUS316L stainless barrel provides durability in compact spaces.
