Airtac PB Pen-type Cylinder PB16X120SCB
The AirTAC Airtac PB Pen-type Cylinder PB16X120SCB is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 120mm 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 PB16X120SCB
The AirTAC PB16X120SCB is a JIS pen-size double-acting single-rod mini cylinder engineered for compact automation. It delivers a robust 100.5 N push and 90.7 N pull at 0.5 MPa, scaling to a maximum 140.7 N push at 0.7 MPa. The slim SUS304 stainless steel barrel and screwed-in covers provide excellent durability in damp or mildly corrosive environments, while keeping weight low for end-of-arm tooling. This specific configuration includes a built-in piston magnet (-S) for position sensing and a CB double clevis back cover for pivoting loads.
Air connections are made via an M5x0.8 port, and the Ø5 mm piston rod features an M10x1.0 rod-end thread for secure load coupling. Traveling at speeds of 50-800 mm/s, the unit relies on a fixed TPU bumper at each end to decelerate the stroke. Because this bumper is not adjustable, high-energy cycles with heavy tooling 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 (Ø16mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 100.5 N | 90.7 N |
| 0.7 MPa (max) | 140.7 N | 126.9 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 PB16X120SCB Is Used
Pivot Actuated Gripper
Ideal for swinging a small parts gripper on a packaging machine, utilizing the CB double clevis to accommodate the pivoting arc while providing 100.5 N of extend force.
Divert Gate Mechanism
Drives a lightweight sorting flap on a conveyor line where the SUS304 stainless build resists washdown moisture and the compact pen-size body fits within tight transfer gaps.
PCB Test Fixture
Moves a testing probe array into position on an electronics assembly line, using the built-in S magnet to trigger an electronic switch and confirm the 120 mm stroke completion.
Is the Airtac PB Pen-type Cylinder PB16X120SCB the Right Cylinder?
When sizing this actuator, plan for a safe working load of about 60 N at 0.5 MPa, which accounts for roughly 60% of the theoretical force to overcome seal friction and ensure smooth travel. Vertically, this translates to lifting about 5.1 kg with a sane 2:1 safety margin. If you need to step down, the Ø12 bore offers 56.5 N push at 0.5 MPa; there is no larger bore in this pen-size family. Keep in mind the thin Ø5 mm rod is designed for coaxial thrust, so over the 120 mm stroke or under off-axis loads, adding an external linear bearing prevents side-load damage. Also, a plain PB body does not hold its position if air pressure drops or the valve is centered—the piston will drift, so an external rod lock is required for fail-safe holding.
Confirm your ordering essentials: 16 mm bore, 120 mm stroke, M5x0.8 port, S magnet for reed or electronic switches, and the CB double clevis mount for your pivoting application.
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 PB16X120SCB FAQ
This 16 mm bore double-acting cylinder provides 100.5 N push and 90.7 N pull at 0.5 MPa, reaching maximums of 140.7 N push and 126.9 N pull at 0.7 MPa. The operating pressure range is 0.15-0.7 MPa, with a proof pressure of 1.2 MPa. It operates at speeds between 50-800 mm/s.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper only decelerates the rod near the stroke end and does not act as a lock. For fail-safe vertical holding, you must add an external stop or rod lock.
