About the Airtac PBR Pencil Type Cylinder PBR10X125SR
The AirTAC PBR10X125SR is a double-acting, single-rod pen-size mini cylinder with a 10mm bore and 125mm stroke. It delivers 39.3N of push force at 0.5MPa. The front cover features M4x0.7 threads, letting you bolt the body straight to a fixture without adding a separate bracket. The SUS316L stainless barrel resists damp and mildly corrosive environments better than a plain body.
Air connects via the M5x0.8 port, while the R back cover provides an axial inlet for clean in-line plumbing. A fixed TPU bumper at each end decelerates the piston near stroke end. Because the -S option includes a built-in piston magnet, you can track position with reed or electronic switches.
Airtac PBR Pencil Type Cylinder PBR10X125SR Technical Specifications
| Model | Airtac PBR Pencil Type Cylinder PBR10X125SR |
|---|---|
| Series | PBR JIS pen-size front-mount cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm |
| Stroke | 125 mm |
| Front-mount thread | M4×0.7 |
| Port size | M5×0.8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 0.7 MPa |
| Proof pressure | 1.2 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 50 – 800 mm/s |
| Cushion | Elastic bumper (both ends) |
| Max standard stroke | Up to 200 mm |
The front cover carries the mounting thread (M4×0.7) so the cylinder bolts directly to a fixture. Barrel is SUS316L stainless. Confirm bore, stroke and back-cover option against the product label before installation.
Theoretical Output Force (Ø10mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 39.3 N | 33.0 N |
| 0.7 MPa (max) | 55.0 N | 46.2 N |
Values are taken from the AirTAC PB/PBR thrust table. Pull acts on the smaller rod-side area, so pull force is lower than push. Size with a friction margin.

Where the Airtac PBR Pencil Type Cylinder PBR10X125SR Is Used
Panel-Mounted Pusher
Bolts directly through the M4x0.7 front thread to push lightweight parts along a conveyor from a fixed panel.
Washdown Test Jig
The SUS316L barrel survives damp testing environments while the compact pen body fits inside small lab fixtures.
In-Line Diverter
Uses the R axial inlet for straight plumbing along a machine frame, actuating a small diverter arm in tight spaces.
Is the Airtac PBR Pencil Type Cylinder PBR10X125SR the Right Cylinder?
For a 10mm bore at 0.5MPa, this model pushes 39.3N and pulls 33N. Stepping down to an 8mm bore drops the push to 25.2N, while a 12mm bore raises it to 56.5N. When bolting this cylinder directly through the front cover, match your fastener size and thread engagement carefully to the M4x0.7 mounting thread, especially on bottom-mounted setups.
The Ø4mm piston rod is built for coaxial thrust; over this 125mm stroke, add an external linear guide to prevent side-load wear. Confirm your bore, stroke, S magnet, and R axial inlet when ordering.
Quick checklist
- ✓ Bolt directly through the front cover (M4×0.7)
- ✓ No room for a separate mounting bracket
- ✓ Force at your working pressure
- ✓ Back cover: U side or R axial inlet
- ✓ Magnet (S) for sensors?
- ✓ SUS316L barrel for damp / corrosive areas
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 0.7 MPa operating pressure.
- check Match bolt size and engagement to the front thread.
- check Take extra care with bolt length on bottom mounting.
- check Keep the load coaxial; avoid side load on the thin rod.
- check Do not dismantle the front or back cover.
Airtac PBR Pencil Type Cylinder PBR10X125SR FAQ
At 0.5MPa, the push force is 39.3N and the pull force is 33N. At the maximum operating pressure of 0.7MPa, the push force is 55N and the pull force is 46.2N. Push force is always greater than pull force because of the single rod.
The front cover has M4x0.7 threads for bolting straight to a fixture, eliminating separate brackets. The S in the model code denotes a built-in piston magnet, allowing you to use reed or electronic switches for position sensing.
