Airtac PB Pen-type Cylinder PB16X35SCB
The AirTAC Airtac PB Pen-type Cylinder PB16X35SCB is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 35mm 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 PB16X35SCB
The AirTAC PB16X35SCB is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It generates 100.5 N of push and 90.7 N of pull at 0.5 MPa, driven through an M5x0.8 port. The slim SUS304 stainless round barrel and screwed-in covers provide excellent durability in damp or mildly corrosive work areas while keeping end-of-arm tooling lightweight.
This variant includes a built-in piston magnet (-S) for position detection using AirTAC reed or electronic switches. It features a CB double clevis back cover for pivoting loads and relies on a fixed TPU bumper at each end to decelerate the stroke. Because the bumper is not adjustable, metering out the exhaust or adding an external shock absorber is recommended when moving real tooling mass at higher speeds.

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 PB16X35SCB Is Used
PCB Depaneling Pivot
Actuates a pivoting cutting blade on an electronics assembly line, utilizing the CB double clevis to maintain smooth angular motion while routing small circuit boards.
Pouch Sealing Clamp
Provides the 100.5 N extend force needed to hold a flexible packaging film steady against a heated sealing bar in a high-speed form-fill machine.
Sorter Diverter Arm
Drives a lightweight routing flap on a package handling conveyor, where the slim stainless body resists ambient humidity and the -S magnet confirms flap position.
Is the Airtac PB Pen-type Cylinder PB16X35SCB the Right Cylinder?
When sizing this 16 mm bore, stepping down to the 12 mm bore yields 56.5 N push at 0.5 MPa, while there is no larger standard bore in this pen-size family. A good practice is to plan for about 60 N of real work at 0.5 MPa (roughly 60% of the theoretical 100.5 N force to account for seal friction), which equates to safely lifting a 5.1 kg vertical load with a 2:1 margin. If your process must hold a load when air is lost or the valve is centered, note that this cylinder will drift and requires an external stop or rod lock.
Confirm your ordering essentials: 16 mm bore, 35 mm stroke, M5x0.8 port, M10x1.0 rod-end thread, -S magnet for sensors, and CB double clevis mount. The Ø5 mm piston rod is designed for coaxial thrust, so for off-axis loads or longer strokes, incorporate an external linear bearing guide to prevent side-loading damage.
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 PB16X35SCB FAQ
At 0.5 MPa this 16 mm bore cylinder provides 100.5 N push and 90.7 N pull. At the maximum operating pressure of 0.7 MPa, it yields 140.7 N push and 126.9 N pull. It operates between 0.15-0.7 MPa, runs at speeds of 50-800 mm/s, and has a proof pressure of 1.2 MPa.
The CB back cover is a double clevis designed for pivoting mountings. Impact deceleration is handled by a fixed TPU bumper at each end rather than an adjustable air cushion, so for heavy tooling at high speeds you should meter-out the exhaust or add an external shock absorber. The cylinder does not hold its position on air loss and will drift without an external rod lock.
