Airtac PB Pen-type Cylinder PB16X220SU
The AirTAC Airtac PB Pen-type Cylinder PB16X220SU is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 220mm 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 PB16X220SU
The AirTAC PB16X220SU is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency motion. It features a slim SUS304 stainless steel round barrel and piston rod, providing excellent durability in damp or mildly corrosive environments. Delivering 100.5 N of push force at 0.5 MPa, this model integrates a built-in piston magnet for position sensing and a U-type 90-degree side air inlet for flat plumbing in space-constrained setups.
With a 16 mm bore and 220 mm stroke, the unit 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 extended length; adding an external guide or linear bearing prevents side-load wear. Air connections use an M5x0.8 port, and the rod-end features an M10x1.0 thread for secure load coupling.

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 PB16X220SU Is Used
PCB Depaneling Router
Drives a low-friction cutting head across 220 mm to singulate printed circuit boards, utilizing the slim stainless body to fit within dense electronics manufacturing machinery.
Pouch Forming Pusher
Actuates a sealing jaw assembly on a vertical form-fill-seal machine, where the 90-degree side inlet keeps plumbing flush against the frame and the 100.5 N thrust firmly folds packaging film.
Sorting Diverter Arm
Extends a lightweight paddle to deflect small parcels on a logistics belt, relying on the built-in magnet to confirm full extension before the next item arrives.
Is the Airtac PB Pen-type Cylinder PB16X220SU the Right Cylinder?
When sizing this actuator, plan for a safe working load of roughly 60 N at 0.5 MPa, which accounts for seal friction and smooth travel. For vertical lifts, this translates to lifting about 5.1 kg safely with a 2:1 margin. If you need slightly less force, stepping down to the 12 mm bore yields 56.5 N push at 0.5 MPa, while staying at 16 mm gives you the maximum standard thrust in this family.
Confirm your ordering essentials: 16 mm bore, 220 mm stroke, M5x0.8 port, S magnet for reed or electronic switches, and the U perpendicular inlet. Note that a plain pen-size 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. Furthermore, at high cycling speeds with real tooling mass, the fixed bumper may bottom out, so metering out the exhaust or adding an external shock absorber is advised.
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 PB16X220SU FAQ
This double-acting cylinder generates 100.5 N push and 90.7 N pull at 0.5 MPa. At the maximum operating pressure of 0.7 MPa, it produces 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 tolerates temperatures from -20 to +70 C.
The S suffix denotes a built-in piston magnet compatible with AirTAC reed or electronic switches for position detection. For end-of-stroke damping, it uses a fixed TPU bumper at each end rather than an adjustable air cushion. If cycling heavy loads at high speeds, you should meter-out the exhaust or add an external shock absorber, as the bumper only decelerates the final few millimeters.
