Airtac PTBR Single Acting Square Head Compact Cylinder PTBR10X15R
The AirTAC Airtac PTBR Single Acting Square Head Compact Cylinder PTBR10X15R 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, 15mm stroke; the return spring resets the rod when air is released.

About the Airtac PTBR Single Acting Square Head Compact Cylinder PTBR10X15R
The AirTAC PTBR10X15R is a JIS pen-size single-acting pull cylinder with a 10mm bore and 15mm 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. The fail-safe extended design ensures the rod stays out during air loss, making it inherently safe for return-to-home tasks.
It features a direct M4x0.7 front-cover mounting thread and a SUS316L stainless barrel. A fixed TPU bumper cushions the end of travel. Because pulling acts on the rod-side annular area, this cylinder yields lower force than a matching push type. Plan for a safe working load of about 14N, which is roughly 60% of the rated figure, to account for friction.

|---|---|
| Series | PTBR JIS pen-size front-mount cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Stroke | 15 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 PTBR10X15R Is Used
Hold-Down Clamping
Uses spring pressure to keep a workpiece extended and clamped, retracting only when air is applied to release the part.
Tensioning Mechanism
Maintains constant pulling tension on a belt or filament, snapping back to the extended home position if the air supply drops.
Retract-to-Open Gate
Spring-extends to block a conveyor lane by default, pulling the gate open only during active sorting cycles.
Is the Airtac PTBR Single Acting Square Head Compact Cylinder PTBR10X15R the Right Cylinder?
When sizing this 10mm bore model, compare it to adjacent options. Dropping to an 8mm bore yields 12.4N net pull at 0.5 MPa, while stepping up to a 12mm bore provides 33.1N. This PTBR10X15R sits in the middle with 23.5N at 0.5 MPa and 36.7N at the 0.7 MPa maximum. The spring requires at least 0.2 MPa to overcome internal resistance before motion begins.
The direct front-mount M4x0.7 thread bolts straight into your fixture, eliminating extra brackets. For vertical lifting, the 23.5N pull safely holds or pulls about 1.2kg with a 2:1 safety margin. Confirm your plumbing uses the R axial inlet back cover 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 (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 PTBR10X15R FAQ
It provides a net pull of 23.5N at 0.5 MPa and 36.7N at the 0.7 MPa maximum. A minimum of 0.2 MPa is required to overcome the spring before the rod retracts. If air is lost, the spring fails safe to the extended position.
It mounts directly via an M4x0.7 thread on the front cover, plumbing air through an R axial inlet on the back cover. The SUS316L stainless barrel resists corrosion. The thin 4mm rod is built for coaxial thrust, so use an external guide for any side loads.
