Airtac PB Pen-type Cylinder PB10X20SULB
The AirTAC Airtac PB Pen-type Cylinder PB10X20SULB is a double-acting pen-size (mini) air cylinder with a Ø10mm bore and 20mm 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 PB10X20SULB
The AirTAC PB10X20SULB is a JIS pen-size double-acting single-rod mini cylinder engineered for compact, high-frequency motion. It features a slim SUS304 stainless steel round barrel and piston rod, offering excellent durability in damp or mildly corrosive environments while keeping weight low for end-of-arm tooling. Delivering 39.3 N of push force at 0.5 MPa, this 10 mm bore unit uses an M5x0.8 port and an M8x1.0 rod-end thread to drive small loads efficiently.
This specific configuration includes a built-in piston magnet (S) for position sensing with AirTAC reed or electronic switches, a U-type 90-degree side air inlet for flat plumbing, and an LB mounting bracket. It operates at speeds of 50-800 mm/s with fixed TPU bumpers at both ends. Because the bumper only decelerates the final few millimeters of travel, high-speed cycles with real tooling mass may require metering out the exhaust or adding an external shock absorber.

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 PB10X20SULB Is Used
PCB Pick-and-Place
Drives a small vacuum nozzle on a pick-and-place head to lift electronic components, utilizing the 2 kg vertical lift capacity and slim body to fit between adjacent circuit boards.
Carton Flap Folding
Extends a narrow metal finger to tuck minor flaps on small pharmaceutical cartons before sealing, relying on the 24 N safe working load to push light cardboard without stalling.
Lab Dispenser Actuation
Moves a micro-pump plunger for precise fluid dispensing in analytical equipment, where the SUS304 build resists humid lab conditions and the U inlet keeps plumbing flat against the chassis.
Is the Airtac PB Pen-type Cylinder PB10X20SULB the Right Cylinder?
When sizing this actuator, plan for a safe working load of roughly 24 N, which is about 60% of the 39.3 N theoretical push at 0.5 MPa, ensuring smooth travel after accounting for seal friction. For vertical lifts, this translates to lifting about 2 kg with a sane 2:1 safety margin. If you need less force, stepping down to the 6 mm bore yields 14.2 N push at 0.5 MPa, while stepping up to the 12 mm bore provides 56.5 N. Note that the thin 4 mm rod is built for coaxial thrust; over long strokes or off-axis loads, add an external guide or linear bearing to prevent side-loading damage.
This PB-type cylinder does not hold its position or load when air is lost or the valve is centered—the piston drifts, and the bumper only decelerates it near stroke end, acting as neither a lock nor a brake. If your application must hold a load without live pressure, an external stop or rod lock is required. Confirm your ordering essentials: 10 mm bore, 20 mm stroke, M5x0.8 port, S magnet, U 90-degree inlet, and LB mount.
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 PB10X20SULB FAQ
This double-acting 10 mm bore cylinder delivers 39.3 N push and 33 N pull at 0.5 MPa, with maximums of 55 N push and 46.2 N pull at 0.7 MPa. The maximum operating pressure is 0.7 MPa, proof pressure is 1.2 MPa, and the operating speed ranges from 50-800 mm/s.
It uses fixed TPU bumpers at both ends, which are not field-adjustable and only decelerate the last few millimeters of travel. The built-in S magnet allows position detection using AirTAC reed or electronic switches, and the LB bracket provides a robust mounting interface for the pen-size body.
