Airtac PTBR Single Acting Square Head Compact Cylinder PTBR10X30R
The AirTAC Airtac PTBR Single Acting Square Head Compact Cylinder PTBR10X30R 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, 30mm stroke; the return spring resets the rod when air is released.

About the Airtac PTBR Single Acting Square Head Compact Cylinder PTBR10X30R
The AirTAC PTBR10X30R is a JIS pen-size single-acting pull cylinder. Air entering the M5x0.8 port retracts the rod, while a spring pushes it back out, ensuring a fail-safe extended state on air loss. It delivers 23.5 N net pull at 0.5 MPa and 36.7 N at 0.7 MPa, with the spring force already deducted.
This model bolts directly to a fixture via its front-cover M4x0.7 thread, saving space without extra brackets. The SUS316L stainless barrel resists corrosion, and a fixed TPU bumper cushions the stroke ends. Because the 4 mm rod is slender, use an external guide for off-axis loads.

| Rod diameter | Ø4 mm |
| Stroke | 30 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 PTBR10X30R Is Used
Hold-Down Clamp
Pulls a small part down against a fixture during machining, with the spring automatically lifting the clamp safely when air is removed.
Retract-to-Open Gate
Uses the front M4x0.7 thread to mount directly on a conveyor diverter, pulling the gate open on signal and springing it closed on air loss.
Web Tensioner
Maintains light pulling tension on a filament or wire, offering a fail-safe extended position that keeps material slack-free if pressure drops.
Is the Airtac PTBR Single Acting Square Head Compact Cylinder PTBR10X30R the Right Cylinder?
This 10 mm bore provides 23.5 N usable pull at 0.5 MPa. If you need less force, the 8 mm bore yields 12.4 N; for heavier pulling, the 12 mm bore offers 33.1 N.
The spring ensures the rod stays out safely during air loss. It mounts directly via the M4x0.7 front-cover thread, and the back cover uses an R axial inlet. Confirm your pressure stays within the 0.2-0.7 MPa range needed for motion.
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 PTBR10X30R FAQ
It provides 23.5 N net pull at 0.5 MPa and 36.7 N at 0.7 MPa. Because it is spring-extended, a minimum pressure of 0.2 MPa is required to overcome the spring and retract the rod.
It mounts directly via the M4x0.7 front-cover thread, eliminating brackets. The barrel is SUS316L stainless steel, and the back cover features an R axial air inlet for inline plumbing.
