Airtac PB Pen-type Cylinder PB16X35CB
The AirTAC Airtac PB Pen-type Cylinder PB16X35CB 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 PB16X35CB
The AirTAC PB16X35CB is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It features a 16mm bore and a 35mm stroke, generating 100.5 N of push force and 90.7 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 variant includes a CB double clevis back cover, allowing the body to pivot smoothly on a pin mount. Air connects via an M5x0.8 port, and the Ø5 mm rod ends in an M10x1.0 thread. End-of-stroke deceleration is handled by a fixed TPU bumper at each end, which absorbs impact over the final few millimeters of travel rather than providing adjustable cushioning.

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 PB16X35CB Is Used
Pivoting Clamp Arm
Swings a lightweight lever to clamp electronic housings on a PCB assembly line, utilizing the CB double clevis to accommodate the arc of the moving fixture.
Flap Folder Mechanism
Actuates a hinged folding blade on a small carton erector, relying on the 100.5 N extend force to tuck corrugated flaps cleanly at high cycling speeds.
Diverter Gate
Pushes a small routing flap on a parcel sorting conveyor to redirect lightweight poly-bagged goods into a packing chute without adding bulk to the frame.
Is the Airtac PB Pen-type Cylinder PB16X35CB the Right Cylinder?
When sizing this actuator, plan for a safe working load of about 60 N (roughly 60% of the 100.5 N theoretical push at 0.5 MPa) to account for seal friction and smooth travel. If your application requires lifting a vertical mass, this unit safely handles around 5.1 kg using a standard 2:1 safety margin. If you need to step down, the adjacent Ø12 bore offers 56.5 N push at 0.5 MPa; there is no larger bore in this pen-size family, so heavier demands require a different profile series.
Because the CB clevis allows pivoting, ensure the rod remains coaxial to avoid side loading the slender Ø5 mm rod. A plain double-acting cylinder does not hold position if air pressure drops or the valve is centered—the piston will drift, and the fixed bumper only decelerates near the end of stroke, so fit an external rod lock for fail-safe holding. To order, confirm the 16mm bore, 35mm stroke, M5x0.8 port, CB clevis back cover, and the absence of a sensor magnet.
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 PB16X35CB FAQ
At 0.5 MPa, this 16mm bore cylinder provides 100.5 N of push (extend) force and 90.7 N of pull (retract) force. At the maximum operating pressure of 0.7 MPa, the push force is 140.7 N and the pull force is 126.9 N. It operates on filtered air between 0.15 and 0.7 MPa, supports speeds from 50 to 800 mm/s, and functions in environments from -20 to +70 C.
The CB back cover is a double clevis designed for pivoting mounts, allowing the cylinder body to swing as the load moves. Instead of adjustable air cushioning, the ends rely on a fixed TPU bumper that absorbs impact over the final few millimeters of travel. For high-speed cycles with heavy tooling mass, you should meter-out the exhaust or add an external shock absorber, as the bumper cannot be field-adjusted.
