Airtac PBR Pencil Type Cylinder PBR10X125U
The AirTAC Airtac PBR Pencil Type Cylinder PBR10X125U 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 PBR10X125U
The AirTAC PBR10X125U is a double-acting single-rod pen-size mini cylinder that provides 39.3 N push and 33 N pull at 0.5 MPa. You bolt it straight to your fixture via the M4x0.7 front-cover thread, eliminating separate brackets to save space. The M5x0.8 air port feeds the chamber, while the SUS316L stainless barrel resists damp or washdown environments better than a plain body.
A fixed TPU bumper at each end decelerates the piston near stroke end. Because the rod is only Ø4 mm, use an external guide for off-axis loads over this 125 mm stroke. Plan for about 24 N of real work at 0.5 MPa to account for seal friction, which lets you lift roughly 2 kg vertically with a safe margin.

| Model | Airtac PBR Pencil Type Cylinder PBR10X125U |
|---|---|
| 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 PBR10X125U Is Used
Panel-Mounted Pusher
Bolts directly through the front cover to push light parts across a tight inspection panel.
Fixture Clamp
Secures small electronic components inside a machining fixture using the direct front thread.
In-Line Diverter
Mounts flat to a conveyor rail to divert small products with its 125 mm stroke.
Is the Airtac PBR Pencil Type Cylinder PBR10X125U the Right Cylinder?
This 10 mm bore outputs 39.3 N push at 0.5 MPa. Stepping down to the 8 mm bore drops push to 25.2 N, while the 12 mm bore raises it to 56.5 N. Match your bolt size and thread engagement to the M4x0.7 front thread, especially on bottom mounting. Confirm your ordering essentials: 10 mm bore, 125 mm stroke, no magnet, and the U 90-degree side inlet for flat plumbing.
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 PBR10X125U FAQ
At 0.5 MPa the push is 39.3 N and pull is 33 N. At the maximum 0.7 MPa operating pressure, push is 55 N and pull is 46.2 N.
The front cover features an M4x0.7 thread for direct fixture mounting. The SUS316L stainless barrel handles damp environments better than standard materials. This model has no sensor magnet and uses a U 90-degree side air inlet.
