Airtac PBR Pencil Type Cylinder PBR10X125SU
The AirTAC Airtac PBR Pencil Type Cylinder PBR10X125SU is a double-acting pen-size mini cylinder with threaded holes in its front cover for direct mounting — no separate bracket needed. It has a Ø10mm bore, 125mm stroke, M4×0.7 front-mount thread and a SUS316L stainless barrel for corrosive settings.

About the Airtac PBR Pencil Type Cylinder PBR10X125SU
The AirTAC PBR10X125SU is a double-acting, single-rod pen-size mini cylinder. It provides about 39.3 N of push force and 33 N of pull force at 0.5 MPa. You bolt it straight to your fixture using the front-cover M4x0.7 thread, which cuts part count and saves space versus a bracketed build. The SUS316L stainless barrel resists damp and mildly corrosive environments better than a plain body.
Air connects via the M5x0.8 port, while the U back cover gives a 90-degree side inlet for flat plumbing. A fixed TPU bumper at each end decelerates the piston near stroke end. The built-in magnet (-S) works with reed or electronic switches. Plan for a safe working load of about 24 N, which is roughly 60% of the 0.5 MPa push figure, to account for seal friction.
Airtac PBR Pencil Type Cylinder PBR10X125SU Technical Specifications
| Model | Airtac PBR Pencil Type Cylinder PBR10X125SU |
|---|---|
| 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 PBR10X125SU Is Used
Panel-Mounted Pusher
Bolts directly through the front cover to push small parts along a conveyor in tight machinery.
Fixture Clamp
Secures delicate electronic components during assembly using the 39.3 N extend force.
In-Line Diverter
Uses the U side inlet for flat plumbing to divert lightweight packages on a high-speed line.
Is the Airtac PBR Pencil Type Cylinder PBR10X125SU the Right Cylinder?
This 10 mm bore yields 39.3 N push at 0.5 MPa. Stepping down to an 8 mm bore drops push to 25.2 N, while moving up to a 12 mm bore raises it to 56.5 N. Match your bolt size and thread engagement to the M4x0.7 front-mount thread, especially on bottom mounting, to prevent loosening. Confirm your ordering essentials: 10 mm bore, 125 mm stroke, S magnet, and U side inlet.
The thin Ø4 mm piston rod handles coaxial thrust well, but over this 125 mm stroke you should add an external guide or linear bearing to prevent side load. The U cover provides a 90-degree side air inlet for flat routing.
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.
