Airtac PB Pen-type Cylinder PB10X70SR
The AirTAC Airtac PB Pen-type Cylinder PB10X70SR is a double-acting pen-size (mini) air cylinder with a Ø10mm bore and 70mm stroke. Its slim round barrel and back cover are stainless steel, the M5×0.8 ports keep plumbing compact, and the fast, low-friction piston suits high-cycle small-part handling.

About the Airtac PB Pen-type Cylinder PB10X70SR
The AirTAC PB10X70SR is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It features a 10mm bore and a 70mm stroke, generating 39.3 N of push and 33 N of pull at 0.5 MPa. The slim SUS304 stainless barrel and piston rod provide corrosion resistance for damp environments while keeping mass low for end-of-arm tooling. The R axial inlet allows direct in-line plumbing.
Equipped with a built-in magnet (-S), this unit supports AirTAC reed or electronic switches for precise position detection. It uses an M5x0.8 air port and an M8x1.0 rod-end thread. Deceleration relies on a fixed TPU bumper at each end, which is not adjustable. Plan for a safe working load of roughly 24 N (about 60% of the 0.5 MPa push) to account for seal friction and smooth travel.

| Rod diameter | Ø4 mm |
| Stroke | 70 mm |
| Acting type | Double acting |
| 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) |

Specifications follow the official AirTAC PB pen-size datasheet. Piston rod and barrel are stainless steel. 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 thrust table. Because pull acts on the rod-side annular area, pull force is always lower than push. Actual usable force is reduced by friction — size with a margin.

Where the Airtac PB Pen-type Cylinder PB10X70SR Is Used
PCB Depaneling Jig
Actuates a routing blade fixture in tight electronics assembly cells, utilizing the slim stainless body to fit between conveyor rails without collision.
Pouch Sealing Press
Closes a lightweight heated jaw on small medical pouches, applying consistent coaxial pressure via the M8x1.0 threaded rod end.
Lab Dispenser Valve
Toggles a micro-dispense valve for reagent dosing, benefiting from the axial R inlet that keeps plumbing flat against the machine frame.
Is the Airtac PB Pen-type Cylinder PB10X70SR the Right Cylinder?
When sizing this 10mm bore actuator, stepping down to a 6mm bore yields 14.2 N push at 0.5 MPa, while stepping up to a 12mm bore provides 56.5 N. This model includes the -S magnet for sensing and the R axial back cover for straight-line air supply. Confirm your required 70mm stroke, M5x0.8 port, and M8x1.0 rod thread during ordering.
Note that a standard PB cylinder drifts when air pressure is lost or the valve is centered; the end bumpers only decelerate the piston near stroke completion and do not act as a locking mechanism. For vertical loads requiring fail-safe holding, an external rod lock or mechanical stop is necessary. Additionally, the 4mm rod is built for coaxial thrust—avoid side loading or add an external linear guide to prevent bending over the 70mm travel.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Slim pen body vs. a standard round cylinder
- ✓ Back cover: CB / U / R inlet direction
- ✓ Magnet (S) for sensors?
- ✓ Mounting: LB / FA / CJ or front thread
- ✓ Keep the load coaxial — avoid side load
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 0.7 MPa operating pressure.
- check Keep the load coaxial; avoid side load on the thin rod.
- check Do not dismantle the front or back cover.
- check Fit dust caps to ports during long-term storage.
- check Installation by qualified personnel per AirTAC docs.
Airtac PB Pen-type Cylinder PB10X70SR FAQ
At 0.5 MPa, the push force is 39.3 N and the pull force is 33 N. At the maximum operating pressure of 0.7 MPa, the push is 55 N and the pull is 46.2 N. The operating pressure range is 0.15-0.7 MPa, with a speed of 50-800 mm/s and a proof pressure of 1.2 MPa.
This model uses fixed TPU bumpers at both ends to decelerate the piston over the last few millimeters; they are not adjustable, so meter-out the exhaust or add an external shock absorber for heavy high-speed loads. The built-in magnet (-S) allows you to mount AirTAC reed or electronic switches along the body for position detection.
