Airtac PTBR Single Acting Square Head Compact Cylinder PTBR10X10R
The AirTAC Airtac PTBR Single Acting Square Head Compact Cylinder PTBR10X10R 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, 10mm stroke; the return spring resets the rod when air is released.

About the Airtac PTBR Single Acting Square Head Compact Cylinder PTBR10X10R
The AirTAC PTBR10X10R is a single-acting pull-type pen cylinder featuring a 10mm bore and 10mm stroke. It provides 23.5N net pull at 0.5MPa and 36.7N at 0.7MPa. Air entering the M5x0.8 port retracts the rod, while a spring extends it out. This fail-safe extended behavior ensures the rod pushes out automatically upon air loss.
You mount it directly via the front-cover M4x0.7 thread, saving space in tight jigs. The SUS316L stainless barrel resists corrosion, and a fixed TPU bumper cushions the stroke ends. Plan for a safe working load of roughly 14N, which is about 60% of the rated 0.5MPa pull force, to account for seal friction.

| 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 (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 PTBR10X10R Is Used
Hold-Down Clamping
Pulls a clamp down onto a workpiece with 23.5N net force. The spring-extend design automatically releases the clamp upward when air pressure drops.
Retract-to-Open Gate
Uses the M4x0.7 front-mount thread to bolt directly to a conveyor diverter gate. Air pulls the gate closed, and the spring opens it safely during shutdown.
Light Tensioner
Applies steady tension to a film or wire strand. The SUS316L barrel prevents corrosion in packaging environments, and the fixed TPU bumper softens the stroke end.
Is the Airtac PTBR Single Acting Square Head Compact Cylinder PTBR10X10R the Right Cylinder?
When sizing this 10mm bore option, consider the neighboring bores. If you need less force, the 8mm version yields 12.4N net pull at 0.5MPa. If your task requires more power, stepping up to the 12mm bore provides 33.1N. This PTBR10X10R gives 23.5N at 0.5MPa. The spring requires a minimum 0.2MPa pressure before motion begins.
Because the unit fails safe extended, it suits hold-down and tensioning tasks where rod-out is the secure state. The direct front-cover M4x0.7 thread eliminates extra brackets. For vertical lifting, expect it to hold or pull about 1.2kg with a sane 2:1 margin. Confirm your plumbing uses the R axial inlet back cover.
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 PTBR10X10R FAQ
It delivers 23.5N net pull at 0.5MPa and 36.7N at 0.7MPa maximum. Because it is spring-extended, a minimum 0.2MPa is required to overcome the spring and retract the rod.
It mounts directly via the front-cover M4x0.7 thread. Air connects through the R axial inlet back cover using an M5x0.8 port. The SUS316L stainless barrel provides a slim, corrosion-resistant body.
