Airtac PB Pen-type Cylinder PB12X100SR
The AirTAC Airtac PB Pen-type Cylinder PB12X100SR is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 100mm 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 PB12X100SR
The AirTAC PB12X100SR is a JIS pen-size double-acting single-rod mini cylinder engineered for tight jigs and light end-of-arm tooling. It features a slim SUS304 stainless barrel and piston rod, offering excellent durability in damp or mildly corrosive environments. Delivering 56.5 N of push force at 0.5 MPa, this 12 mm bore unit uses an M5x0.8 port and an M10x1.0 rod-end thread. The R axial air inlet supports clean in-line plumbing.
This 100 mm stroke model includes a built-in piston magnet (-S) for position detection using AirTAC reed or electronic switches. It relies on a fixed TPU bumper at each end to decelerate impact. Because the rod is a slender Ø5 mm, maintaining coaxial thrust is critical over this longer stroke—add an external guide if the load is off-axis.

| Model | Airtac PB Pen-type Cylinder PB12X100SR |
|---|---|
| Series | PB JIS pen-size mini cylinder |
| Bore size | Ø12 mm |
| Rod diameter | Ø5 mm |
| Stroke | 100 mm |
| Acting type | Double acting |
| Port size | M5×0.8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 0.7 MPa |
| Proof pressure | 1.2 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 50 – 800 mm/s |
| Cushion | Elastic bumper (both ends) |
| Max standard stroke | Up to 300 mm |
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 PB12X100SR Is Used
Blister Pack Sealing
Cycles a 100 mm stroke to lower a thin heat-seal head onto blister card stock, where the fixed TPU bumper softens the final impact at high frequency.
Lab Sample Dispenser
Actuates a fluid valve probe in a compact diagnostic machine, benefiting from the SUS304 stainless construction to resist mild chemical splashes.
Is the Airtac PB Pen-type Cylinder PB12X100SR 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.
A plain pen-type body does not hold its load if air pressure drops or the valve is centred; the piston will drift, and the bumper only decelerates near stroke end. For fail-safe holding, specify an external rod lock. Confirm your ordering essentials: 12 mm bore, 100 mm stroke, M5x0.8 port, S magnet, and R axial inlet.
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 PB12X100SR FAQ
The PB12X100SR generates a push force of 56.5 N and a pull force of 46.7 N at 0.5 MPa. At the maximum operating pressure of 0.7 MPa, it yields 79.1 N push and 65.4 N pull. The operating pressure range is 0.15-0.7 MPa, with a speed of 50-800 mm/s.
The -S code indicates a built-in piston magnet compatible with AirTAC reed or electronic switches. End damping is handled by a fixed TPU bumper at each end; it is not adjustable, so for high-speed tooling mass you should meter-out the exhaust or add an external shock absorber.
