Airtac PB Pen-type Cylinder PB10X70SU
The AirTAC Airtac PB Pen-type Cylinder PB10X70SU 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 PB10X70SU
The AirTAC PB10X70SU is a JIS pen-size double-acting mini cylinder engineered for compact, high-frequency motion. It features a 10mm bore and a 70mm stroke, generating 39.3 N of push force and 33 N of pull force at 0.5 MPa. The slim SUS304 stainless steel barrel and piston rod provide excellent durability in damp or mildly corrosive environments while keeping end-of-arm tooling extremely light.
This specific configuration includes a built-in piston magnet (-S) for position detection and a U-type back cover with a 90-degree side air inlet for flat plumbing along the machine frame. Air connects via an M5x0.8 port, and the rod end utilizes an M8x1.0 thread. Deceleration is handled by a fixed TPU bumper at each end, which absorbs impact over the final few millimeters of travel.

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 PB10X70SU Is Used
PCB Pick & Place
Drives a small vacuum nozzle to lift electronic components, utilizing the 2 kg vertical lift capacity and slim profile to fit densely packed SMT machinery.
Blister Pack Sorting
Pushes lightweight plastic blister packs into a diverting chute, where the fixed TPU bumpers quietly absorb the impact of high-frequency cycling.
Lab Reagent Dispensing
Actuates a micro-valve for precise fluid dosing, relying on the SUS304 build to resist humidity and the U-type side inlet to keep plumbing flush against the cabinet wall.
Is the Airtac PB Pen-type Cylinder PB10X70SU the Right Cylinder?
When sizing this actuator, plan for a safe working load of about 24 N (roughly 60% of the 0.5 MPa theoretical push) to account for seal friction and smooth travel. This equates to lifting about 2 kg vertically with a sane 2:1 safety margin. If your application requires less force, stepping down to the 6mm bore yields 14.2 N of push at 0.5 MPa, while moving up to the 12mm bore provides 56.5 N. Remember that the thin 4mm piston rod is built for coaxial thrust, so over this 70mm stroke you should add an external guide or linear bearing if the load is off-axis.
A standard double-acting cylinder does not hold its position if air pressure is lost or the valve is centered, as the piston will drift and the bumper only decelerates near the stroke end. For a fail-safe hold, specify an external stop or rod lock. To order, confirm the 10mm bore, 70mm stroke, M5x0.8 port, S magnet, U 90-degree side inlet, and your required mounting bracket.
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 PB10X70SU 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 force is 55 N and the pull force is 46.2 N. The operating pressure range is 0.15-0.7 MPa, with a speed of 50-800 mm/s.
The built-in magnet supports AirTAC reed or electronic switches for end-of-stroke detection, and fixed TPU bumpers decelerate the piston at the ends. However, it does not function as a lock; if air is lost, the load will drift. You must add an external rod lock for fail-safe holding, and at high speeds with real mass, consider metering out the exhaust or adding a shock absorber.
