Airtac PB Pen-type Cylinder PB12X90U
The AirTAC Airtac PB Pen-type Cylinder PB12X90U is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 90mm 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 PB12X90U
The AirTAC PB12X90U is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency motion. It features a 12mm bore and a 90mm stroke, generating 56.5 N of push force and 46.7 N of pull force at 0.5 MPa. The slim SUS304 stainless steel barrel and piston rod provide durability in damp or mildly corrosive environments while keeping weight low for end-of-arm tooling. This configuration includes a U-type back cover, orienting the M5x0.8 air inlet 90 degrees to the side for flat plumbing in space-constrained machinery.
End-of-stroke deceleration relies on a fixed TPU bumper at each end rather than an adjustable air cushion. Because the bumper only absorbs energy over the final few millimeters, high-speed cycles with heavy tooling mass may require metering out the exhaust or adding an external shock absorber. The 5mm piston rod utilizes an M10x1.0 end thread for secure load coupling and is designed strictly for coaxial thrust to prevent side-loading damage.

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 (Ø12mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 56.5 N | 46.7 N |
| 0.7 MPa (max) | 79.1 N | 65.4 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 PB12X90U Is Used
PCB Depaneling Jig
Actuates a small cutting blade or clamping fixture in tight electronics assembly equipment where the 90-degree side inlet keeps plumbing flush against the machine frame.
Label Applicator Tamp
Provides 56.5 N of extend force at 0.5 MPa to press adhesive labels onto lightweight cartons, benefiting from the fixed TPU bumper to soften the tamp impact at high cycling speeds.
Sorting Diverter Arm
Pushes small parcels on a packaging line; the SUS304 stainless body resists humid washdown environments while the 90mm stroke moves parts cleanly between adjacent belts.
Is the Airtac PB Pen-type Cylinder PB12X90U the Right Cylinder?
If you need slightly less force, the neighboring 10mm bore provides 39.3 N of push at 0.5 MPa; stepping up to the 16mm bore yields 100.5 N for heavier moves.
To confirm your ordering essentials for this model: verify the 12mm bore, 90mm stroke, M5x0.8 port, and the U-type 90-degree side inlet. Note that a plain PB 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. An external rod lock or mechanical stop is required for fail-safe load 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 PB12X90U FAQ
At 0.5 MPa, this 12mm bore double-acting cylinder provides 56.5 N of push (extend) force and 46.7 N of pull (retract) force. At the maximum operating pressure of 0.7 MPa, the push force is 79.1 N and the pull force is 65.4 N. The operating pressure range is 0.15-0.7 MPa, with a speed range of 50-800 mm/s.
The U back cover features a 90-degree side air inlet (M5x0.8) that allows flat plumbing in tight spaces. Instead of an adjustable air cushion, it uses a fixed TPU bumper at each end to decelerate the piston over the final few millimeters. For high-speed or heavy loads, you should meter-out the exhaust or add an external shock absorber, as the bumper is not adjustable.
