Airtac PB Pen-type Cylinder PB12X90SR
The AirTAC Airtac PB Pen-type Cylinder PB12X90SR 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 PB12X90SR
The AirTAC PB12X90SR is a JIS pen-size double-acting single-rod mini cylinder engineered for tight spaces. It features a 12mm bore and a 90mm stroke, producing 56.5 N of push force and 46.7 N of pull force at 0.5 MPa. The slim SUS304 stainless barrel and piston rod provide excellent durability in damp or mildly corrosive environments, keeping end-of-arm tooling lightweight.
This specific configuration includes an S-coded piston magnet for position sensing with AirTAC reed or electronic switches, and an R axial air inlet for in-line plumbing. Air connects via an M5x0.8 port, and the rod-end features an M10x1.0 thread. Operating speed ranges from 50-800 mm/s, with fixed TPU bumpers at both ends to absorb end-of-stroke impact.

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 PB12X90SR Is Used
PCB Depaneling Router
Actuates a cutting head guide on an electronics assembly line, utilizing the 90mm stroke and slim profile to maneuver within dense fixture layouts.
Blister Pack Sealing
Provides consistent downward pressure on small medical blister packs, using the 56.5 N push force to secure foil lids without crushing the plastic cavities.
Lab Sample Dispenser
Drives a pipetting mechanism in diagnostic equipment where the compact stainless body resists humidity and the S magnet confirms fluid delivery positions.
Is the Airtac PB Pen-type Cylinder PB12X90SR the Right Cylinder?
When sizing this actuator, stepping down to the Ø10 bore yields 39.3 N push at 0.5 MPa, while stepping up to the Ø16 bore provides 100.5 N. For the PB12X90SR, plan for a safe working load of roughly 34 N (about 60% of the 56.5 N theoretical force) to account for seal friction and smooth travel. This equates to lifting approximately 2.9 kg vertically with a sane 2:1 safety margin. Remember that a plain cylinder drifts when air is lost or the valve is centered; an external rod lock is required for fail-safe holding. Confirm your ordering essentials: 12mm bore, 90mm stroke, S magnet, R axial inlet, and M5x0.8 port.
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 PB12X90SR FAQ
At 0.5 MPa, the push force is 56.5 N and the pull force is 46.7 N. 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 of 50-800 mm/s.
It uses a fixed TPU bumper at each end that decelerates the piston over the last few millimeters; it is not an adjustable air cushion or a locking brake. For high-speed cycles with heavy tooling, meter-out the exhaust or add an external shock absorber. The built-in S magnet allows tracking by AirTAC reed or electronic switches.
