Airtac PTBR Single Acting Square Head Compact Cylinder PTBR16X10R
The AirTAC Airtac PTBR Single Acting Square Head Compact Cylinder PTBR16X10R 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 Ø16mm bore, 10mm stroke; the return spring resets the rod when air is released.

About the Airtac PTBR Single Acting Square Head Compact Cylinder PTBR16X10R
The AirTAC PTBR16X10R is a JIS pen-size single-acting pull cylinder with a 16 mm bore and 10 mm stroke. Air entering the M5x0.8 port retracts the rod, while an internal spring pushes it back out, ensuring a fail-safe extended state upon air loss. It delivers 65 N of net pull at 0.5 MPa and 101.2 N at 0.7 MPa.
This model bolts directly to a fixture via its M5x0.8 front-cover thread, saving space in tight assemblies. The SUS316L stainless barrel provides corrosion resistance, and a fixed TPU bumper cushions the stroke ends. For smooth operation, plan for a safe working load of about 39 N, which accounts for seal friction.

| 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 100 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 (Ø16mm)
| Pressure | Net pull force |
|---|---|
| 0.5 MPa | 65.0 N |
| 0.7 MPa (max) | 101.2 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 PTBR16X10R Is Used
Hold-Down Clamp
Uses spring pressure to keep a workpiece extended, then air-pulls to release the clamp for automated tooling changes.
Retract-to-Open Gate
Spring holds a small access gate closed safely; applying air retracts the rod to open the gate for part transfer.
Tensioner Arm
Maintains constant outward tension on a belt or web, pulling back only when pneumatic pressure is applied.
Is the Airtac PTBR Single Acting Square Head Compact Cylinder PTBR16X10R the Right Cylinder?
When sizing this 16 mm bore unit, compare its 65 N net pull at 0.5 MPa against the smaller 12 mm bore (33.1 N) or the larger 20 mm bore if available. The spring requires a minimum 0.2 MPa pressure to retract the rod. This fail-safe extend behavior is ideal for tensioning or hold-down tasks where rod-out is the safe state.
The direct front-cover M5x0.8 thread simplifies mounting without extra brackets. It uses the R axial-inlet back cover for inline plumbing. Confirm your fixture thread engagement and note that no magnet is installed on this variant.
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 ≤ 100 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 PTBR16X10R FAQ
It provides 65 N net pull at 0.5 MPa and 101.2 N at 0.7 MPa. Because it is single-acting pull, a minimum of 0.2 MPa is required to overcome the spring and retract the rod. If air is lost, the spring forces the rod back out to a fail-safe extended position.
It mounts directly via the M5x0.8 front-cover thread and uses an R axial-inlet back cover. The barrel is made of SUS316L stainless steel for durability. This specific model does not include a sensor magnet.
