Airtac PB Pen-type Cylinder PB16X20SCB
The AirTAC Airtac PB Pen-type Cylinder PB16X20SCB is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 20mm 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 PB16X20SCB
The AirTAC PB16X20SCB is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency motion. It delivers a robust 100.5 N push and 90.7 N pull at 0.5 MPa, making it the highest force class in this slim family. The SUS304 stainless barrel and piston rod provide reliable durability in damp or mildly corrosive environments, while the lightweight round body saves payload on fast end-of-arm tooling.
This specific configuration includes an S-coded piston magnet for position sensing using AirTAC reed or electronic switches, and a CB double clevis back cover that accommodates pivoting loads. The M5x0.8 port and M10x1.0 rod-end thread simplify plumbing and load coupling. Because it uses a fixed TPU bumper at each end rather than an adjustable air cushion, you should meter-out the exhaust or add an external shock absorber when cycling heavy tooling at high 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 PB16X20SCB Is Used
Pivoting Clamp Arm
Ideal for actuating a short pivoting clamp arm on a CNC fixture, utilizing the CB double clevis to swing and secure aluminum housings during machining.
Carton Flap Folder
Drives a compact folding blade on a packaging line to tuck corrugated carton flaps, taking advantage of the 100.5 N extend force to overcome board stiffness.
Light Part Ejector
Ejects molded plastic parts from a vertical chute, where the short 20mm stroke and integrated S magnet confirm ejection completion for the pickup robot.
Is the Airtac PB Pen-type Cylinder PB16X20SCB the Right Cylinder?
Selecting the PB16X20SCB gives you the maximum thrust available in this mini series. If you need slightly less force, stepping down to the Ø12 bore yields a 56.5 N push at 0.5 MPa; as this is the largest standard pen-size option, there is no larger bore to step up to within the PB family. For this 16mm bore, plan for a safe working load of about 60 N (roughly 60% of the 0.5 MPa theoretical force) to account for seal friction and smooth travel. You can also estimate it will lift about 5.1 kg vertically with a sane 2:1 safety margin.
Keep in mind the thin Ø5 mm piston rod is designed for coaxial thrust, so if your application involves off-axis loading, add an external guide or linear bearing to prevent binding. A plain double-acting cylinder like this does not hold its position if air pressure is lost or the valve is centered—the piston will drift, and the bumper only decelerates near the stroke end, so an external rod lock is required for fail-safe holding. When ordering, confirm the 16mm bore, 20mm stroke, M5x0.8 port, S magnet, and CB double clevis mount.
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 PB16X20SCB FAQ
At 0.5 MPa, this double-acting 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 increases to 140.7 N and the pull to 126.9 N. It operates on filtered air at 0.15-0.7 MPa with a speed range of 50-800 mm/s.
The CB back cover is a double clevis joint designed for applications requiring a pivoting load connection. At the stroke ends, the cylinder relies on a fixed TPU bumper to decelerate the piston. This bumper is not adjustable and does not act as a brake, so for high-speed cycling with heavy tooling, you should meter-out the exhaust or install an external shock absorber.
