Airtac PB Pen-type Cylinder PB10X70U
The AirTAC Airtac PB Pen-type Cylinder PB10X70U 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 PB10X70U
The AirTAC PB10X70U is a JIS pen-size double-acting single-rod mini cylinder engineered for compact, high-frequency small-part motion. It generates 39.3 N of push force and 33 N of pull force at 0.5 MPa, utilizing a 10 mm bore and a 70 mm stroke. The slim SUS304 stainless barrel and piston rod provide reliable durability in damp or mildly corrosive work areas while keeping end-of-arm tooling weight to an absolute minimum.
This specific configuration includes a U-type back cover, providing a 90-degree perpendicular air inlet for flat plumbing in space-constrained jigs. Air connects via an M5x0.8 port, and the Ø4 mm rod features an M8x1.0 end thread for secure load coupling. Deceleration is handled by a fixed TPU bumper at each end, which absorbs impact over the final few millimeters of travel rather than acting as a locking mechanism.

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 PB10X70U Is Used
PCB Pick-and-Place
Drives a small vacuum gripper to lift and position delicate printed circuit boards within an electronics assembly line, utilizing the 39.3 N push force to overcome spring-loaded fixture resistance.
Carton Flap Folding
Actuates a lightweight folding arm to tuck minor flaps on small pharmaceutical cartons before sealing, fitting easily into tight machinery gaps thanks to the slim stainless barrel.
Connector Sorting
Pushes plastic wire connectors into designated chutes on a high-speed sorting carousel, relying on the fixed TPU bumpers to absorb impact at the end of the 70 mm extension.
Is the Airtac PB Pen-type Cylinder PB10X70U the Right Cylinder?
Selecting this 10 mm bore yields 39.3 N push at 0.5 MPa, sitting neatly between the smaller Ø6 bore (14.2 N push) and the larger Ø12 bore (56.5 N push). For real-world work, plan for a safe working load of about 24 N (roughly 60% of the theoretical 0.5 MPa force) to account for seal friction and smooth travel, or expect to lift about 2 kg vertically with a sane 2:1 margin.
When ordering, confirm the 10 mm bore, 70 mm stroke, M5x0.8 port, and the U-type 90-degree side inlet. Because the thin Ø4 mm piston rod is designed strictly for coaxial thrust, add an external linear guide if your jig imposes any side load. Note that a plain PB body does not hold its position if air pressure drops; the piston will drift, so an external rod lock is required for fail-safe holding.
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 PB10X70U FAQ
This double-acting cylinder delivers 39.3 N push and 33 N pull at 0.5 MPa. At the maximum operating pressure of 0.7 MPa, it yields 55 N push and 46.2 N pull. It operates between 0.15-0.7 MPa, runs at speeds of 50-800 mm/s, and has a proof pressure of 1.2 MPa.
It uses a fixed TPU bumper at each end to decelerate the piston over the last few millimeters; this is not an adjustable air cushion or a locking brake. If moving high masses at speed, meter-out the exhaust or add an external shock absorber. The cylinder will drift and lose its position if air is lost, so an external stop is needed for fail-safe holding.
